As described above, the electrical equipment cover 20 downside cover plate 21 and face side cover plate 22 combined, as shown in Figure 8 in the past Surface lateral indoor set 100 is installed.Figure 17 is the major part longitudinal section related to the installation of electrical equipment cover 20, shows lower side cover The long side sidepiece pawl 21b of plate 21 card hangs state.As shown in figure 17, the preceding surface lower portions of water-collecting tray assembly 6 compare electric appliance unit 30 protrude downwards, and towards face side.Moreover, in the front end for the part that it is protruded downwards, with side prominent upward Formula hangs projection 6c formed with card.The card hangs projection 6d can be in left and right directions and multiple long side sidepiece pawl 21b of downside cover plate 21 Be provided with separating same intervals it is multiple, can also be continuous on the longer ground of left and right directions.

In addition, in the front-surface side of water-collecting tray assembly 6, thermal insulation barriers 6c is provided with a manner of being contacted with water-collecting tray 6a, So as to avoid in cooling operation because of the water-collecting tray 6a of cool condensation water cooling that water-collecting tray 6a is dropped onto from heat exchanger 2, And the moisture in room air is condensed in the front-surface side of water-collecting tray assembly 6.Card is hung projection 6c and exposed from thermal insulation barriers 6c. Wherein, the polystyrene foam formed using foam injection molding is carried out to polystyrene (PS), as thermal insulation barriers 6c.

As shown in figure 17, the long side sidepiece pawl 21b of downside cover plate 21 is made first by the lower section of electric appliance unit 30, will all Long side sidepiece pawl 21b blocks in a covered manner is hung on card extension projection 6d.In this condition, the deadweight of electrical equipment cover 20 hangs projection by card 6d is supported, therefore even if operator for example lets go from electrical equipment cover 20, electrical equipment cover 20 will not also depart from from indoor set 100.Then, with The short side sidepiece pawl 21a of downside cover plate 21 be respectively at be formed at right side faceplate panels 13 and left side faceplate panels 14 lower flange before The mode of the position of the square hole 44 of lateral incline 421, the positioning of the left and right directions of downside cover plate 21 is carried out, and will be each from the state Individual short side sidepiece pawl 21a is inserted in corresponding square hole 44.

Operator by the left and right sides of downside cover plate 21, respectively from the side of decorative appearance face 211 towards lower flange on front side of tilt Face 421 presses, so as to the short side sidepiece pawl 21a of side two respectively to corresponding square hole 44 peritreme press, be allowed to Inner elastic deforms and enters square hole 44.Figure 18 is the main portion for the pawl fixture construction for representing short side sidepiece pawl 21a and square hole 44 Divide sectional view.As shown in figure 18, to inner side (center side of left and right directions) elastic deformation and the short side sidepiece pawl 21a of insertion, if The front end hook part of convex by square hole 44, then releases elastic deformation, rear side card of the front end hook part in square hole 44 laterally Peritreme is hung on, so as to complete pawl fixture construction.

Thus, the left and right sides of downside cover plate 21 respectively with before the lower flange of right side faceplate panels 13 and left side faceplate panels 14 Lateral incline 421 is overlapping, and downside cover plate 21 is overall to be tilted forwards with the identical angle of inclined plane 421 on front side of lower flange.And And pass through the short side sidepiece pawl 21a of the left and right sides and the pawl fixture construction of square hole 44 and multiple long side sidepiece pawls of rear side The construction that 21b hooks to the raised 6c of card extension, is fixed on indoor set 100 by downside cover plate 21.

After downside cover plate 21 to be installed to fixation, face side cover plate 22 is fixed on indoor set 100.Downside cover plate 21 is To be fixed, face side cover plate 22 is connected via hook 21c with downside cover plate 21, thus relative to the right flank of face side cover plate 22 The positioning of the front flange 43 of panel 13 and left side faceplate panels 14 has been completed.Therefore if operator divides from the side of decorative appearance face 221 The left and right sides forward flanges 43 of face side cover plate 22 are not pressed, then by the respective upper jaw 21a in the left and right of positive mask plate 22 The front square hole 45 on the top of forward flanges 43 inserts.

Figure 19 is the main portion sectional view for the pawl fixture construction for representing upper jaw 22a and front square hole 45.Upper jaw 22a While to inner side elastic deformation, while enter front square hole 45 in the same manner as the short brink pawl 21a of downside cover plate 21, if convex Front end hook part is laterally by front square hole 45, then elastic deformation is released from, and front end hook part is at the back side of front square hole 45 Side card is hung on peritreme, so as to complete pawl fixture construction.

Though the pawl fixture construction for the upper jaw 22a and front square hole 45 for passing through the left and right sides, face side cover plate 22 is installed It is fixed, but further according to the reasons why aftermentioned, screw also is applied to face side cover plate 22 and fixed.As shown in figure 8, utilize screw 47 Three positions of bottom and central upper to the left and right sides are fixed.Pass through the screw at the bottom Liang Ge positions of the left and right sides Screw 47 after through hole 22d is screwed into screw 46, and the screw 46 is formed at right side faceplate panels 13 and left side faceplate panels 14 are respective The bottom of front flange 43 so that face side cover plate 22 is screwed to front flange 43.In addition, led to by the screw of central upper Screw 47 after the 22d of hole, the screw (not shown) on the preceding surface for being arranged at filter unit 9 is screwed into, so that positive side cover Plate 22 is screwed to filter unit 9.The screw threads for fastening of the central upper can also be configured to, and screw is formed at into electrical equipment list The mounting substrate 30 of member 30, and make face side cover plate 22 and the screw threads for fastening of mounting substrate 31.

More than, the installation of electrical equipment cover 20 terminates.In top view, in rectangular-shaped blow-off outlet 4, the downside of electrical equipment cover 20 The back side side end face of cover plate 21 undertakes to form its leading edge, and the anterior end surface of web 15 is undertaken to form its back edge, right side faceplate panels 13 and the respective lower flange 42 of left side faceplate panels 14 end undertake to be formed its left and right lateral margin.

Afterwards, front appearance decoration panel 16 is installed on to the front surface of indoor set 100, so as to the group of indoor set 100 Install into.Figure 20 is the stereogram for representing to install front appearance decoration panel 16.It is (outer at the back side of front appearance decoration panel 16 See decorative cover reverse side) left and right sides top, be integrally formed with rotary shaft 16a, above-mentioned rotary shaft 16a respectively and pass through insertion And be installed on bearing 431, the bearing 431 be formed at right side faceplate panels 13 and the respective front flange 43 of left side faceplate panels 14 it is upper Portion.

Rotary shaft 16a can rotatably be supported on bearing 431, and front appearance decoration panel 16 is with the rotary shaft 16a on top Rotated for fulcrum in above-below direction, so as to which the preceding surface of indoor set 100 is opened and closed.In front appearance decoration panel In the case that 16 close, the static pawl 16b of the lower backside of the left and right sides of front appearance decoration panel 16 is formed at, by preceding The capture unit 432 that the bottom of flange 43 is formed clamps, so as to maintain stable inactive state.The front appearance decoration that can be opened and closed Panel 16 is located at the front surface of indoor set 100.

If front appearance decoration panel 16 rotate upward as defined in angle and open, on the construction of bearing, rotate Axle 16a is maintained at the position, so as to maintain the state opened with the defined angle.In this condition, user can be carried out The cleaning operation of filter unit 9.In the indoor set 100, the rule of the open state of its front appearance decoration panel 16 are maintained Fixed angle (being set to maintain open angle below), turns into 70 degree upward from the state of closing.If further beaten than the angle Open, then rotary shaft 16a can dismount relative to bearing 431, thus allow for removing, pacifying for front appearance decoration panel 16 Dress.

Fig. 1 is the state for the metope that the indoor set 100 so assembled is arranged at interior by simulation, and seen from front obliquely downward Examine the stereogram of indoor set 100.Front appearance decoration panel 16 is closed, and in stopped process is operated, up-down wind direction board 7 is also switched off Blow-off outlet 4, this corresponds to Fig. 8 longitudinal section.As shown in Fig. 1, Fig. 8, the electrical equipment cover 20 of the lower section of electric appliance unit 30 is covered Downside cover plate 21, the front appearance decoration panel in the state of the front end for the blow-off outlet 4 closed by up-down wind direction board 7 and closing Between 16 lower end, in its faced chamber of decorative appearance face 211, infrared ray sensor 37a is filled by gauge hole 21d from outward appearance Facing 211 protrudes, but electric appliance unit 30 does not expose.It is unrelated with the open and-shut mode of front appearance decoration panel 16, downside cover plate 21 Decorative appearance face 211 expose to interior.

By the way that the downside cover plate 21 is formed as filling with right side faceplate panels 13 and left side faceplate panels 14 or front appearance The identical color of decoration panel 16, thus indoor set 100 can turn into the design with unified sense, and be used as different colours, It is used as emphasizing colour in the design of indoor set 100.Downside cover plate 21 is as previously mentioned towards front obliquely downward, but electric appliance unit 30 Remote controller signal receiving and transmitting part 34 be formed as its preceding surface with display device 35 and downside cover plate 21 is almost parallel.That is, remote control Signal transmitting and receiving portion 34 and the preceding surface of display device 35, with almost parallel state and the reverse side in the decorative appearance face of downside cover plate 21 212 is relative.Therefore display content caused by display device 35, lower side cover can be passed through in the operation process of machine 100 indoors Plate 21, so as to which indoor user can identify the display content.In addition, can equally pass through downside cover plate 21, carry out using red The remote control of outside line signal and the two-way communication of indoor set 100.

Moreover, user is for example in order to carry out the maintenance of filter unit 9, and open front appearance decoration panel 16.Herein, The maintenance of filter unit 9 refers to：The disposal box of filter cleaning means is removed, the dust for being stranded in inside is thrown away and pacifies again Dress removes installation etc. again after air cleaner is washed to it and is allowed to dry.Figure 21 is front appearance decoration panel 16 maintain open angles open in the state of indoor set 100 stereogram, it is same with Fig. 1 carried out from front obliquely downward from.

As shown in figure 21, even if front appearance decoration panel 16 opens, face side cover plate 22 also covers electric appliance unit 30 Front, therefore electric appliance unit 30, and electrical equipment list are configured in the front of heat exchanger 2 (being herein lower front heat exchanger 2b) Member 30 is not exposed to front.The emergency operation switch 36 only from window 22e.Emergency operation switch 36 also occurs in remote control sometimes Utilize, therefore will not be blocked by face side cover plate 22 for user during failure, but user can be made from window 22e to from front Know its presence, and be in exercisable state.

Face side cover plate 22 includes the various distributions of access and exit control substrate housings 32, and electric appliance unit 30 is hidden in into its back side Side, therefore user will not touch electric appliance unit 30 during maintenance filter unit 9.Therefore card it will not hang and pull out by mistake Go out distribution or cut-out distribution, so as to safely implement maintenance operation.

In addition, the face side of synthetic resin same with right side faceplate panels 13, left side faceplate panels 14 and downside cover plate 21 Cover plate 22 exposes to front, therefore compared with the situation that surface is exposed for metal control base board housing 32, various distributions etc., Aesthetic property is increased substantially, even if in order to which the indoor set 100 of a part for the indoor design to undertaking room carries out maintenance operation, And front appearance decoration panel 16 is in open state, it user is noticed electronic unit, distribution, so as to damage The aesthetic property higher in the state of closing of evil front appearance decoration panel 16.

By the way that positive side cover 22 is formed as into same with right side faceplate panels 13 and left side faceplate panels 14 or downside cover plate 21 Color, so as in the state of the opening of front appearance decoration panel 16, can also ensure that the design with unified sense.In addition, Even if be formed as with above-mentioned part not identical color, also can be used in emphasizing colour.

Downside cover plate 21 is the board member of the resin forming of the elongated substantially rectangular shape of left and right directions, but is not based only on left and right The short side sidepiece pawl 21a of both sides fixture construction, and the overleaf long side sidepiece of side, multiple long side sidepiece pawl 21b are in left and right The card that direction is hung on the preceding surface of water-collecting tray assembly 6 with the spacing card of appropriateness hangs projection 6d, in addition, the long side sidepiece of face side The face side cover plate 22 of right side faceplate panels 13 and left side faceplate panels 14 is fixed in screw, is formed as in left and right directions with appropriateness Interval hung by multiple hook 21c under state, therefore will not in the lateral direction bend because of aging and bloat downwards, from And aesthetic property can be maintained for a long time.In addition, in the indoor set 100, respectively using six long sides sidepiece pawl 21b and hook 21c, but The number of above-mentioned part, at intervals of design item, properly selected according to the size of downside cover plate 21.

In addition, face side cover plate 22 is also the board member of the resin forming of the elongated substantially rectangular shape of left and right directions, but not The upper jaw 22a of left and right sides fixture construction is only used at an upper portion thereof, and it is tight in center and the progress screw thread of filter unit 9 Gu and be threadably secured respectively with front flange 43 in bottom and in the left and right sides, and multiple hook 21c of downside cover plate 21 The retaining wall 22c of the reverse side 222 in decorative appearance face is hung on the interval of appropriateness, card in left and right directions, to bear downside cover plate 21 Deadweight, therefore will not in the lateral direction bend and bloat forwards due to aging.

Face side cover plate 22 can using in the bottom that hinge connection constructs as fulcrum, forward downward rotate, but not only with Pawl fixture construction, and being fixed using screw 47 at three positions, therefore even if user maintenance filter unit 9 mistake Cheng Zhong, misconnection contact face side cover plate 22 or some positions of collision, are also not in that upper jaw 22a departs from from front square hole 45, And the situation that face side cover plate 22 is rotated, opened occurs, from situation about surprisingly exposing without electric appliance unit 30.

In addition, the long side sidepiece of front side is fixed on the face side cover plate of screw fixation by downside cover plate 21 via hook 21c 22, so as to coordinate the overleaf long side sidepiece pawl 21b that side is carried out fixation, make the downside cover plate 21 under the state can not elasticity change Shape, so as to which hooks of the short side sidepiece pawl 21a to square hole 44 can not be released.Therefore in the state of the fixation of face side cover plate 22, under Side cover plate 21 without departing from.User will not remove the positive side cover unrelated with filter unit 9 in maintenance filter unit 9 The screw 47 of plate 22, therefore be not in the situation that user surprisingly departs from electrical equipment cover 20.

Moreover, the wiring operation related to electric appliance unit 30, inspection are carried out after indoor set 100 is set to indoor wall Look into, the maintenance of reconditioning work when, the electrical equipment cover 20 plays huge effect.Machine 100 checks indoors, there occurs the situation of failure During lower repairing, attendant implements the work of the investigation, repairing, replacing of the various electronic units of electric appliance unit 30 etc Industry.Attendant is first turned on or removed front appearance decoration panel 16 when carrying out the maintenance of electric appliance unit 30, repairing.This Sample face side cover plate 22 exposes, therefore pulls down the screw 47 at three positions of fixed face side cover plate 22.

In the state of the fastening carried out by screw 47 is released from, the top of face side cover plate 22 is only with by the left and right sides Upper jaw 22a carry out fixation, as long as therefore attendant hold top and be pulled to nearby, then with insertion when on the contrary, on Portion pawl 22a front end hook part while by the peritreme pressing of front square hole 45 and to inner side elastic deformation, while from front square hole 45 extract.Thus upper jaw 22a pawl fixture construction is released from.

If upper jaw 22a fixation is released from, face side cover plate 22 can be via the hook constructed as hinge connection 21c, relative to using short side sidepiece pawl 21a and long side sidepiece pawl 21b and the downside cover plate 21 of fixation rotates, therefore can be near Topple over front side.So turning into makes face side cover plate 22 to the state for nearby rotating and opening, can be by the preceding table of electric appliance unit 30 Surface side opens.Figure 22 is the stereogram for the state for representing to make face side cover plate 22 rotate and open.In the figure, taken in operation Lower front appearance decoration panel 16, in Figure 22 and Figure 23 described later, front appearance decoration panel 16 is not shown.

Face side cover plate 22 tilts to the downside cover plate 21 and the reverse side 212,222 in mutual decorative appearance face shown in Figure 16 Formed obtuse angle turns into 165 degree or so.So by making face side cover plate 22 rotate to tilt, so as to as shown in figure 22, electrical equipment The front surface opened of unit 30, therefore attendant can confirm the situation of electric appliance unit 30 from oblique upper, can carry out range estimation tune Look into.But in this condition, can not carry out preceding surface turns into the remote control receiving and transmitting signal dress for being abreast configured at downside cover plate 21 Put the 34 range estimation investigation with the preceding surface of display device 35.

In addition, if attendant applies from the state is pulled to power nearby by face side cover plate 22, via hook 21c under Side cover plate 21 acts on the power for being intended to pull open downside cover plate 21 from inclined plane 421 on front side of lower flange, so as to the short brink of the left and right sides Portion pawl 21a respectively while to inner side elastic deformation, while being extracted from square hole 44.Thus short side sidepiece pawl 21a pawl fixture construction It is released from.

The long side sidepiece pawl 21b of rear side, the card to cover water-collecting tray assembly 6 carry out card extension in a manner of hanging projection 6d, Therefore the state being released from as short side sidepiece pawl 21a fixation, therefore attendant is only by downside cover plate 21 and face side Cover plate 22 lifts, it becomes possible to releases long side sidepiece pawl 21b to the raised 6d of card extension hook.Attendant is by long side sidepiece pawl 21b hook releases, and is pulled on hand, so as to complete to remove electrical equipment cover 20.

Figure 23 is the stereogram of indoor set 100 in the state of removing after electrical equipment cover 20, is removed with the same manner as Figure 22 outside front See decoration panel 16.As shown in figure 23, by removing electrical equipment cover 20, so as to which electric appliance unit 30 is located at front surface, and turn into The front of the electric appliance unit 30 and lower section opening are without the state blocked.Therefore it can substantially ensure that attendant is carried out and electricity The working space of the related inspection of device unit 30, repairing, part replacement etc., so as to easily carry out above-mentioned operation.And Attendant need not carry out the action of turns due, can from positive object of observation electronic unit, and meanwhile carry out operation, from And it can safe and accurately carry out operation.

, it is necessary to the frequency control higher than other electric components checked in multiple electric components of electric appliance unit 30 are arranged at Substrate 32a processed, only the lid 32c by removing control base board housing 32 from Figure 23 state, it becomes possible to carry out Inspection.If take Lower cover 32c, then control base board 32a exposes towards front, therefore can easily implement using Inspection of tester etc..And And detect failure even in control base board 32a and in the case of must not being changed without as new control base board, if opening lid 32c, Plug, the control base board 32a dismounting in control base board 32a various distributions can be then attached, so that also can be easy Ground carries out the replacement operation of new and old substrate.

Other electric components including the remote controller signal receiving and transmitting part 34 towards front obliquely downward, also can while from Front observation, while the operation such as checked, repaired, being changed in sufficient working space, therefore can easily carry out operation, And it can safe and accurately carry out operation.In addition, remove electrical equipment cover 20 and carry out the inspection related to electric appliance unit 30, During reconditioning work, in the example that Figure 23 is represented, though having removed front appearance decoration panel 16, it can not also remove outside front See decoration panel 16, and with maintain open angle open in the state of carry out operation.If finish the necessary of electric component Operation, then attendant the electrical equipment cover 20 removed is installed from downside cover plate 21 according to above-mentioned order, so as to again The secondary higher state of aesthetic property for returning to covering and blocking electric appliance unit 30.

In addition, in the indoor set 100, the left and right ends of electric appliance unit 30 are nearby covered in right flank face in front respectively The front flange 43 of plate 13 and left side faceplate panels 14.Because only left side faceplate panels 14 cover mounting substrate 31, therefore position is not present In the electric component of the rear side of front flange 43, but right side faceplate panels 13 cover an electric component that is, terminal board 38.The end Sub- platform 38 has function of the connection from power outlet, the distribution of outdoor unit (and not shown), but because the frequency of failure is few, Therefore the rear side positioned at front flange 43 is allowed to herein.

Thus it is not inspection, the reconditioning work that can not carry out terminal board 38.Right side faceplate panels 13 and left side faceplate panels 14 also as described above, is the part that back housing 11 is installed on before electrical equipment cover 20 is installed, the shape after electrical equipment cover 20 is removed Under state, after the metope of interior is arranged at, also it can remove from back housing 11 and install again.It is low in frequency But in the case of needing the operation related to terminal board 38, it can be implemented by removing right side faceplate panels 13.If in addition, remove The both sides of right side faceplate panels 13 and left side faceplate panels 14, then, also can be by electricity even in being arranged under the situation of metope of interior Device unit 30 is overall to be removed and installs again.

Alternatively, it is also possible to be configured to spread all over front of the whole region using the covering electric appliance unit 30 of face side cover plate 22, In this case, the pawl of face side cover plate 22 is fixed and screw threads for fastening, can be pair with the mounting substrate 31 of electric appliance unit 30 As come carry out.

In the electrical equipment cover 20 of the indoor set 100, using hook 21c as face side cover plate 22 relative to fixed lower side cover The hinge connection construction (be rotatably connected construction) of plate 21, but can also be constructed using other hinge connections.Either which kind of hinge Chain link constructs, as long as can make the face side cover plate 22 abreast installed with vertical direction attached with its lower end in the normal state Near is fulcrum, rotates forwards, can discharge the front of electric appliance unit 30.

For example, it is also possible to be connected the front end of downside cover plate 21 with the lower end of face side cover plate 22 with thin-walled piece, make this thin Wall flaps elastic deformation, face side cover plate 22 can be made to rotate forwards.Using in the case of this thin-walled hinge, if from rotation And the face side cover plate 22 for the state opened decontrols hand, then rotated because of the elastic force of thin-walled piece to closing direction so as to close.Separately Outside, in the case where removing downside cover plate 21 from the state of opening, if being intended to face side cover plate 22 being pulled to nearby, thin-walled piece has It may extend or cut off, it is therefore desirable to directly hold front end, the side of downside cover plate 21, and assign and be intended to the inclination on front side of lower flange The power that face 421 is left.If but using thin-walled hinge, the advantages of rotational angle of increase face side cover plate 22 be present.

In the case of hook 21c, constructively, in order to depart from hook 21c, face side cover plate 22 can only be turned to under The parallel nearby place of side cover plate 21, in the indoor set 100, face side cover plate 22 is from the angle that common installment state can rotate Spend for 50 degree or so.But if using thin-walled hinge, the angle that can also allow to rotate is more than 90 degree, can be significantly The preceding surface of electric appliance unit 30 is discharged, can more easily be carried out so as to the Inspection of attendant.

In addition, being constructed as other hinge connections, can also be set in a side of downside cover plate 21 and face side cover plate 22 The axle extended in left-right direction, the bearing chimeric with the axle is set in the opposing party, and front can be made in a manner of as hinge Side cover plate 22 rotates.In this case, if face side cover plate 22 will obtain more than the 90 degree angles that can be rotated, if it has to Between the respective long side sidepiece of downside cover plate 21 and face side cover plate 22 of connection, axle and bearing are configured, therefore in front The lower end of side cover plate 22 and the front end of downside cover plate 21, and gap is produced in the part without axle and bearing, so as in electricity Under 20 common installment state of device cover, it is possible to observe electric appliance unit 30 from the gap.In the decorative appearance face of either one In the case of axle and bearing are configured with reverse side, gap, but the bottom of face side cover plate 22 and downside cover plate 21 will not be produced Front end nearby contact, so as to same with hook 21c, limit excessive rotation.

In the indoor set of in general air conditioner, the upper table faceplate panels 10 of described clathrate, the right side in the indoor set 100 Side panel 13, left side faceplate panels 14, backplate 15 and downside cover plate 21, framework is integrally molded so as using resin mostly, And back housing 11 is fixed in a manner of making it from front cover heating exchanger 2, to form the construction of framework.In the situation Under, if opening front appearance decoration panel 16, the lower front heat exchanger 2b electric appliance unit 30 in front is configured to just Show out, in addition, when carrying out inspection, the reconditioning work of electric appliance unit 30, because a part for the framework is (equivalent to indoor set The part of 100 downside cover plate 21) covering electric appliance unit 30 lower section, therefore, it is difficult to carry out operation, in order to obtain sufficient work Industry space is, it is necessary to which the framework is all removed.

But the indoor set 100 of present embodiment, before the bottom of the heat exchanger 2 than 1 forward side of Air Blast fan Side, is configured with electric appliance unit 30 and possesses electrical equipment cover 20, the electrical equipment cover 20 is configured to include：Cover the lower section of the electric appliance unit 30 And the downside cover plate 21 and face side cover plate 22 in front.Moreover, the downside cover plate 21 of the lower section of covering electric appliance unit 30 is only The right side faceplate panels 13 for the framework to form the indoor set 100 and the separate part of left side faceplate panels 14 are stood on, can be removably It is installed on right side faceplate panels 13 and left side faceplate panels 14.In addition the face side cover plate 22 in the front of the electric appliance unit 30 is covered, Also right side faceplate panels 13 and left side faceplate panels 14 can be removably installed on.
