Unload the preparation of instrument, dissolved material, interface accessory, acidity detection instrument such as pH value reagent paper etc..
Extracting tool: typically have water pipe dental forceps, adjustable wrench, box spanner, inner hexagon spanner external member, cutting pliers, screw
The common tools such as cutter.
Dissolved material: for the purpose of safety, the general citric acid monohydrate granule selecting safety non-toxic, it is a kind of food
Level, the acidic leach material of the common easy buying in market, in use will not to human body produce toxic and side effects, will not be to by scale removal
Water heater is internal produces corrosiveness, just can continue normally with water cavity of clean water and pipe interior as long as scale removal is complete
Use water heater.
Interface accessory: typically have various 4 points of bores to 6 points of bores the inside and outside joint of rustless steel, double end loose joint rustless steel
Heatproof flexible pipe, raw material band, rubber cushion etc..
2, the intake-outlet joint of water heater, the dismounting of sewage draining exit: conventionally dismantle corresponding interface general
It is association installation method and the method for dismounting of grasping water supply pipe joint to the requirement that the operator using scaler is most basic
Basic general knowledge.
3, according to water heater type the most to be cleaned, the solution outlet tube 6 of corresponding type kind and return duct 7 are carried out
Connect.
Have a little it is important to note that when dismantling the sewage draining exit of Domestic water storage formula electric heater, due to hot water herein
The substantial amounts of hot water of device internal reservoir, before the incrustation scale removing this water heater, must allow client stop one evening in advance
The heating function of water heater and closedown power supply so that it is water temperature inside avoids the scald of personnel below 30 DEG C；To put on during dismounting
Raincoat, to prevent discharge outlet plug or magnesium rod from sluicing the most in a large number and clothes of getting wet when screwing out.
4, after connecting outlet tube 6 and return duct 7, acid solution bucket 1 is poured into tap water and comes according to the difference of type
The water yield of decision water, in general, is that minimum need is used to the water consumption of gas heater and instant electric water heater's scale removal

The dissolving of the internal incrustation scale of hydrophone, the effectively dissolving material i.e. citric acid monohydrate granule contained by acid solution can gradually use up, and dissolves
Ability is as well as reduction, so effect and the effect of acid solution should be monitored by operator in timing.
Note: pH value is at 1-7, and numerical value the least expression acidity is the strongest, the citric acid monohydrate granule that the water of isodose adds
The biggest acid solution of dosage is the highest with regard to concentration, the strongest to the solvability of incrustation scale；The acid solution water temperature simultaneously heated is the highest,
The strongest to the solvability of incrustation scale.
During use, a test strip of tearing from reagent paper basis, clamp by hands or tweezers and be immersed in solution tank 1, observe
Its color change, then take up the pH value relatively determining solution to the corresponding vitta in standard color comparison card.It is known that
The acidity of current solution, pH value is the least, and acidity is the strongest.
In acid solution being described when pH value acid solution being detected is reduced to 6.5-7, citric acid is by the most depleted,
At this moment to decide whether that stopping scale removal operation completes work with reference to the service life of this water heater.In general, the time is used
Water heater below 5 years, incrustation scale is not to pile up the thickest, can remove complete in the scale removal time through 2-3h；Now, may be used
To terminate the scale removal work of water heater.
If the use time is the water heater of more than 5 years, the heat pipe 2 that adds that can first stop solution tank 1 heats, return duct
Outer comb after the backflow discharging valve 11 of 7 is put at the sewage draining exit of toilet, opens backflow discharging valve 11 and allows within water heater
Useless acid solution is discharged in municipal administration drainage.
After drained for the acid pickle of this water heater, closing volume discharging valve 11, open recycle control valve 10, start against
Circulation canal；Repeat to add water and add the step of citric acid granule, and be again circulated the work dissolving incrustation scale.
From the point of view of the waste liquid color contrast of twice dissolving scale removal, general primary waste liquid color is just as dense washing water of rice
The same milky turbidity liquid is the most granular with thick incrustation scale, secondary waste liquid color be inclined brown somewhat muddy this
Time can see that the electric heating tube 2 in solution tank 1.
7, when completing above-mentioned scale removal work, complete for discharging of waste liquid after, continuation, from the continuous injected clear water of solution tank 1, allows water
4 clear water of pump pump into and are carried out remaining waste work inside water heater；To then storage-type electric water heater, preferably clear water
Again to externally discharged waste water after filling it up with.
After the water flowed out at blow-off pipe has become clarification, close power supply and stop water pump 4, pull down the outlet tube of scaler
6 and return duct 7, again take back the original corresponding water-system pipeline of water heater the most permissible.
Scale removal special purpose interface I 121 and scale removal is blocked with heatproof aging-resistant plug when routine use solar water heater
Special purpose interface II 122；Back-out when needing scale removal in the plug connection of scale removal special purpose interface I 121 and scale removal special purpose interface II 122
