Swimming Pool Filter User Manual
MODULE CLEANING PROCEDURE
Risk of chemical burns. Do not attempt to acid clean the filter or
module. If the filter requires 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 pressure. See also “When to Clean the
Filter,” at left.
NOTICE: Do not expose the filter module to sunlight for any extended period
of time.
NOTICE: When sanitizing your pool using PHMB (polyhexamethylene bi-
quanide based) cleaners, use only PHMB cleaners to clean the module. When
using PHMB sanitizers, the filter module MUST be cleaned more thoroughly
and frequently than for a pool using chlorine. Follow manufacturer’s instruc-
tions 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 entire module surface. Allow module to drain.
3. Inspect the module. If necessary, repeat the washing operation. If the mod-
ule 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 removed by hosing
down module. Be sure to dispose of spent chemicals according to all applica-
ble 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 chemi-
cal cleaning; rinse filter and elements completely before returning to service.
If filter cannot be isolated, remove media and clean at another location. Follow
chemical manufacturer’s instructions 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 direc-
tions.
2. If soaking is required, remove the module from the filter 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.

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 foun-
tains or pool cleaners may be noticeably
affected by the normal decrease in flow as
the filter becomes dirty. If so, clean the fil-
ter more frequently (that is, at a pressure
increase of less than 10 PSI) in order to
maintain the required flow.
