  • the present invention also includes a method of cleaning the filter assembly 400 .
  • the filter cartridge 405 can be cleansed of coarse direct and debris by pressure washing, ensuring that between the pleats of the cartridge are washed. It has been found that fine particles are more easily removed from the pleats when the cartridge 405 is dry. Therefore, it is preferable that after pressure washing the cartridge 405 it should be allowed to dry and then carefully brushed. The pleats, however, should not be scrubbed. Cleaning or scrubbing the filter cartridge 405 , specifically the pleats, too vigorously will wear it much faster than simply hosing it off.
  • Suntan oils, body oils, algae, and the like can form a coat of film on the pleats of the filter cartridge 405 , which oftentimes can not be thoroughly removed by pressure washing. Such films of oils and/or algae can quickly clog the filter's pores, and thus greatly reduce filtration. Therefore, it is preferable to remove such materials from the filter cartridge as soon as possible.

  • the locking ring 740 slightly tighten the locking ring 740 and rotate the diverter fitting 735 upwardly to cause water horizontally under the water surface to point away from the housing 205 , or more specifically the skimmer intake area. It is preferable that the diverter fitting 735 not be pointed directly toward the skimmer intake area, as this will decrease the skimming and filtration, because water is not being forced about the pool 100 .
  • the locking ring 740 can then be tightened once the desired position of the diverter fitting 735 is determined.
  • the diverter fitting 735 can be positioned downwardly—towards the base 110 of the pool 100 —to assist in keeping settlement from building along the bottom of the pool 100 .

  • the vacuum hose should not be used alone, that is without the pool vacuum, as liner damage, to the bottom of the pool, can occur. Also, it is preferred that one not vacuum with the strainer basket 510 or with the filter cartridge 405 removed, as pump blockage and/or damage can occur. Further, it is preferred that the vacuum hose not be left hanging out of the pool, as a siphon can occur draining the pool.
  • the pump assembly 300 When vacuuming is complete, the pump assembly 300 , should again be turned off.
