FILTER CLEANING PROCEDURE
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 thoroughly and frequently than for a pool using
chlorine. Follow manufacturer’s instructions carefully.
Use of any other type of cleaners with PHMB pool sani-
tizers will void the filter’s warranty.
With hose, wash foreign material from inside of tank.
Avoid washing debris into outlet port.
Be sure inside surface of tank is clean.
Keep track of filter operating pressure. When pressure
reaches 10 PSI (70 kPa) above initial operating pres-
sure, clean filter element.
If filter is used with a spa, soak element (see “Special
Cleaning Instructions,” Page 9) at each regular clean-
ing.
Filter elements are too heavy for safe lifting
when wet and dirty. To avoid back injury, clean and
drain elements as far as possible in operating position
in filter tank. Have two people lift elements and lift with
care. Follow cleaning procedure given below.
A. Cleaning in Place Procedure:
1. Follow steps one through six under
“Disassembly”, Page 5.
2. With a garden hose, hose as much dirt as possible
off of filter elements while they are still in place in-
side the tank (See recommendations, below, right).
Allow tank to drain completely. Make sure that waste
water disposal complies with local codes and ordi-
nances.
3. Lift out center element and hose it down thor-
oughly. Allow to drain.
4. With large element still in tank, hose down both
inner and outer pleats
5. Inspect large element. If it is still dirty, allow it to
drain thoroughly, lift it out of tank and repeat wash-
ing operation; then go to Step 6. If it is clean, got to
Step 7.
Filter elements are heavy when wet and
dirty. To avoid back injury, allow filter element to
drain completely before removing from tank. Have
two people lift element and lift with care.
6. Once it is clean, allow large element to drain thor-
oughly, then reinstall in filter tank.
NOTICE: If this cleaning method does not remove
stubborn deposits, use “Special Cleaning
Instructions”, at right.
7. Reinstall center element
8. Follow steps one through eight under “Assembly”,
Page 5.
B. Special Cleaning Instructions:
Use this procedure to clean scale or oils which are not
removed by simply hosing down and scrubbing ele-
ment. 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.

Follow these recommendations for easier cleaning with a
garden hose:
1. Prepare to get wet!
2. Use a soft flow nozzle which will reduce spray around filter.
3. Move around element while spraying to reach entire sur-
face.
4. Repeat wash-down process for inside of element. Hold
nozzle as close to inside of pleats as possible.
NOTICE: BE SURE all dirt and foreign material is washed
away from INSIDE pleats of element.
5. Drain elements as much as possible before trying to lift
them.
