NOTICE: Some pool disinfectants may clog filter media.
To maximize media-life and filter cycle time, closely fol-
low disinfectant manufacturers instructions when clean-
ing pool or filter.
GENERAL
INFORMATION
Hazardous pressure. Can cause severe
injury or major property damage from tank blow up.
Release all pressure and read instructions before work-
ing on filter.
Clean a new pool as well as possible before filling pool
and operating filter. Excess dirt and large particles of
foreign matter in the system can cause serious damage
to the filter and pump.
With a cartridge filter system in place and operating cor-
rectly, clean water is returned to the pool faster than the
pool water is being contaminated. A typical pool installa-
tion will require approximately one week to obtain and
maintain the sparkle that your filter is capable of giving
you.
Keep pool water pH at recommended level (7.2 to 7.6).
Be sure clamps are in place and knobs are securely
tightened before starting filter.
Maintain pressure gauge in good working order.
Replace gauge if it fails or is damaged.
Make sure internal air bleed tube and air bleed filter
(Key Nos. 9 and 10, Page 10) are in place before oper-
ating filter. Clean air bleed periodically.
If filter is improperly disassembled or as-
sembled, it may explode under pressure! To avoid dan-
ger of severe injury or major property damage, always
follow service instructions in this manual when working
on filter!
NEVER operate this filter system at more
than 50 pounds per square inch (50 PSI/345kPa) pres-
sure!
On a new pool installation, we recommend:
1. Disassemble the filter after the initial cleanup.
To prevent severe injury or major prop-
erty damage, follow exactly “Filter
Disassembly/Assembly Procedure” on Page 5.
2. Hose down the element assembly to remove contami-
nants.
INSTALLATION -
GENERAL
Installation of filter should only be done by qualified,
licensed personnel.
Cleaning interval is based on pressure differential, not
on length of time filter is operated. Different areas and
water conditions will have different normal cleaning in-
tervals.
Filter mount must
Provide space and lighting for easy access for routine
maintenance.
Provide adequate ventilation and drainage for pump.
Be protected from weather and reasonably level.
Be less than three feet above pool water level.
Be as close to pool as possible to reduce line loss from
pipe friction.
Piping
All piping must conform to local and state plumbing and
sanitary codes.
If filter clamps are
adjusted or removed
Never use pipe joint sealing compound on pipe and fit-
tings that are plastic or may come into contact with plas-
tic. Use only Teflon tape, Plasto-Joint Stik® or Silastic
732®** on PVC pipe and fittings; pipe joint compound
may cause stress cracking of plastic components. Use
pipe joint compounds only on metal-to-metal joints.
Support pipe independently to prevent strains on filter or
pump.
Use 2” or larger pipe to reduce pressure losses.
NOTICE: High flow rates may require larger pipe to pro-
duce adequate flow through filter.
Check local codes.
Fittings restrict flow; for best efficiency use fewest pos-
sible fittings.
under pressure,
Filter pumps require
hazardous voltage
which can shock, burn,
or cause death
tank may explode,
causing severe injury or
major property damage.

filter and deforming filter elements.
NOTICE: Damaging filter elements through excessive
heat voids the warranty.
Do not use selector valves (i.e., slide or multiport etc.)
with this filter. Filter cannot be backwashed. See Page 6
for cleaning information.
Electrical
BE SURE filter grounding and bonding meets local and
National Electrical Code standards. All wiring, ground-
ing and bonding of associated equipment must meet
local and National Electrical Code standards.
Valves
Provide isolation valves to allow for easy servicing of filter.
A check valve installed between pool and filter inlet will
prevent contaminants from draining back into pool.
A check valve installed between filter and heater will
prevent hot water from heater from backing up into the

6. Being careful not to damage Cord ring (Key No. 23,
Page 10), lift upper tank half (Key No. 24, Page 10)
off of lower tank half (Key No. 22, Page 10).
INITIAL START-UP
Turn pump OFF before starting procedure.
Properly seat filter clamps and securely tighten clamp
knobs before proceeding.
Read “Warning Instructions For Clamp Assembly” decal
on tank.
Assembly:
1. Remove Cord Ring slowly to avoid stretching or tearing
it.
2. Inspect Cord Ring (Key No. 23, Page 10) for cuts,
nicks, etc. If damaged, replace with a new one.
Water pressure in filter must not exceed 50 PSI (345
kPa) under any circumstances.
3. Clean Cord Ring area of tank half (both halves) and
Cord Ring.
1. Open air release valve (Key No. 3, Page 12) located
on top of filter tank head.
2. Start pump.
3. When a steady stream of water comes from air re-
lease valve, close valve.
4. After filter is operating, record filter pressure gage
reading in owner’s manual for future use.
NOTICE: When installed on a new pool, filter element
may need cleaning after approximately 48 hours of opera-
tion.
NOTICE: A new filter may discharge foam upon initial
start-up. This non-toxic foam is a normal consequence
of the microban treatment process and should disap-
pear after a few minutes of operation.
NOTICE: A new or recently cleaned filter element may
pass some foreign material until it builds up a sufficient
coating to stop all “fines”. This is normal; a short opera-
tional period should correct the condition.
4. Carefully install Cord Ring and upper tank half (Key
No. 24, Page 10).
NOTICE: Be sure upper tank half contacts Cord Ring
surface evenly and seal area is clean and free from dirt.
Do not lubricate Cord Ring; lubricants may cause the
Ring to swell.
5. Install clamps. Do not tighten clamps yet.
6. See Figure 3 for clamp tightening sequence. Tighten
all clamp knobs securely hand tight.
NOTICE: To equalize stresses on tank, be sure to
tighten clamps in sequence shown. DO NOT work your
way around the filter tightening adjacent clamps.
7. Open isolation valves.
8. Follow directions under “Initial Startup”.
Check pressure gauge; if pressure has risen more than 10
PSI (70 kPa) above startup pressure, remove and clean el-
ement.

B. Special Cleaning Instructions:
FILTER CLEANING PROCEDURE
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.
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.
Figure 3 - Hose down elements thoroughly.
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.
Figure 4 - Clean inside as well as outside of elements.
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.
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.
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.
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.
7. Reinstall center element
8. Follow steps one through eight under “Assembly”,
Page 5.

THE WARRANTY!
Risk of fire or explosion. Isolate filter from
system before chemical cleaning; rinse filter and ele-
ments 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 manu-
facturer. Do not allow cleaning chemicals to mix or to
come in contact with chlorines, bromines, other chemi-
cals, or chemical feed devices.
Winterizing
1. Stop pump.

5. Disassemble filter.
3. Sponge or spray elements according to chemical
manufacturer’s directions. Leave elements in operat-
ing position or remove and clean elsewhere, de-
pending on filter location, chemicals used, and
chemical manufacturers instructions (see warning
above).
4. If soaking is required, remove elements from filter
body and submerge in a separate tank. Follow
cleaner manufacturer’s instructions to mix enough
chemical cleaner to soak element. Soaking may
require four to six hours or more.
To avoid severe injury or major prop-
erty damage, exactly follow instruc-
tions under “Disassembly” (Page 5)!

C. Pool Water Not Clear:
TROUBLESHOOTING
GUIDE
1. Chlorine dosage too low; maintain adequate
chlorine residual (consult pool professional for
recommendation).
A. Short Cycle:
Time between cleanings will vary with each installa-
tion and between different areas of the country. The
following causes and remedies are for cycle times
shorter than normal for your area.
NOTICE: Some pool disinfectants may clog filter
media. To maximize media-life and filter cycle time,
closely follow disinfectant manufacturers instructions
when cleaning pool or filter.
1. Chlorine residual too low; maintain proper residual
(consult pool professional for recommendation).
2. Flow rate too high; restrict flow to rated capacity of
filter (see instruction decal on filter).
3. Filter too small; install larger filter or additional filter.
4. Unstable water; consult pool professional.
5. Filter element not cleaned properly or plugged with
algae, iron, calcium, etc. - see “Special Cleaning
Instructions”, Page 6.
2. Element cloth torn or punctured; replace element.
3. Filter too small, flow too low, or daily operating
time too short, giving inadequate turnover rate;
consult dealer to verify that equipment is properly
sized for your pool.
4. Pump too large - overpumping - reduce flow rate.
5. Filter installed backward - replumb.
D. Long Recovery Time After Heavy Usage:
1. Residual Chlorine level is too low - add chlorine.
2. Filter too small - replace with larger unit.
3. Pump too large - reduce flow rate.
E. Filter Bypasses Dirt:
To avoid severe injury or major prop-
erty damage, exactly follow instruc-
tions under “Disassembly” and
“Assembly” (Page 5)!
6. Iron in water - use oversize filter running at a flow
rate of 3/8 to 1/2 GPM/sq. ft.; see cleaning instruc-
tions, Page 6.
7. Heavy or improper application of powdered chlo-
rine or chlorine pills using a binder; see “Special
Cleaning Instructions”, Page 6.
8. Algae in pool - Apply heavy dose of chlorine or al-
gaecide as recommended by pool manufacturer.
Continue until algae is controlled.
1. Air bleed tube and/or tube filter not in position.
Exactly follow instructions in “Filter
Disassembly/Assembly Procedure”, Page 5, and
reinstall correctly.
2. Element cloth torn or punctured; replace element.
3. Filter element is not seated properly in lower tank
half; follow instructions under “Filter
Disassembly/Reassembly”, Page 5, and reposition
properly.
4. Filter is plumbed backwards and element cloth is
ruptured - replumb properly and replace element.
5. Colloidal fines (very small suspended dirt particles)
are present and passing through element cover-
ing. Floc with alum, or if fines have already settled,
vacuum to waste.
B. Low flow:
1. Element is plugged; see “Special Cleaning
Instructions”, Page 6.
2. Pipe blocked downstream from filter; remove ob-
struction.
3. Piping too small; replace with larger pipe (consult
dealer for recommendation).
4. Pump hair and lint trap is plugged - empty and
clean.
5. Pump impeller and diffuser worn - replace with new
parts. Consult pump owner’s manual for informa-
tion.
