MODULE CLEANING PRO- CEDURE

Risk of chemical burns. Do not attempt to acid clean the filter or module. If the filter re-

quires acid cleaning, have a trained pool professional do the job.

Follow all steps in the “Disassembly” section of this manual.

The filter module should be removed and cleaned when pressure rises more than 10 psi (69 kPa) above startup

When to Clean the Filter

The filter module should normally be cleaned when the pressure gauge reading increases 10 PSI over the start-up pressure (record the start-up pressure under “Owner’s Information”, Page 3).

In some pools, accessories such as fountains or pool cleaners may be noticeably affected by the normal decrease in flow as the filter becomes dirty. If so, clean the filter more frequently (that is, at a pressure increase of less than 10 PSI) in order to maintain the re- quired flow.

pressure. See also “When to Clean the Filter,” below.

NOTICE: Do not expose the filter module to sunlight for any extended period of time.

NOTICE: When sanitizing your pool using PHMB (poly- hexamethylene biquanide based) cleaners, use only PHMB cleaners to clean the module. When using PHMB sanitizers, the filter module MUST be cleaned more thor- oughly and frequently than for a pool using chlorine. Follow manufacturer’s instructions carefully. Use of any other type of cleansers with PHMB pool sanitizers will void the filter’s warranty.

NOTICE: Avoid washing filter debris into the outlet port. Remove drain plug and flush foreign material from inside of tank before removing filter module.

1.With a hose equipped with a soft flow nozzle, wash as much dirt as possible off of the filter module while it is still inside the tank. Allow tank to drain completely.

2.Make sure that the inside of the tank is clean. Lift out the module and hose it down thoroughly. Spray the en- tire module surface. Allow module to drain.

3.Inspect the module. If necessary, repeat the washing operation. If the module is damaged, replace it.

NOTICE: If this cleaning method does not remove all deposits, see “Special Cleaning Instructions” section in this manual.

4.Inspect and clean air bleed filter at top of module.

5.Follow all steps in the “Assembly” and “Initial Startup” sections of this manual.

Special Cleaning Instructions:

Use this procedure to clean scale or oils which are not re- moved by hosing down module. Be sure to dispose of spent chemicals according to all applicable codes and waste disposal ordinances. Use a soft stream nozzle to minimize flying water and spray.

Risk of fire or explosion. Isolate filter from system before chemical cleaning; rinse filter

and elements completely before returning to service. If filter cannot be isolated, remove media and clean at an- other location. Follow chemical manufacturer’s instruc- tions for use. Do not mix chemicals except as directed by manufacturer. Do not allow cleaning chemicals to mix with or to come in contact with chlorine, bromines, other chemicals, or chemical feed devices.

1.Sponge or spray the module according to chemical manufacturer’s directions.

2.If soaking is required, remove the module from the fil- ter tank and submerge it in a separate tank. Follow cleaner manufacturer’s instructions carefully.

3.After completing chemical manufacturer’s instructions, drain and rinse the module completely. Dispose of cleaners in accordance with local codes and disposal ordinances.

4.Rinse the inside of the filter tank. Drain it completely.

5.Follow instructions in the “Assembly” and “Initial Startup” sections of this manual.
