Incorrectly installed or tested equipment may fail, causing
severe injury or property damage. Have a trained pool professional perform all pressure tests. Read and follow instructions in
owner's manual when installing and operating equipment.
1. Do not connect system to a high pressure or city water system.
2. Use equipment only in a pool or spa installation.
3. Trapped air in system can cause explosion. BE SURE all air is out of system
before operating or testing equipment.
Before pressure testing, make the following safety checks:
• Check all clamps, bolts, lids, and system accessories before testing.
• Release all air in system before testing.
• Tighten Sta-Rite trap lids to 30 ft. lbs. (4.1 kg-cm) torque for testing.
• Water pressure for test must be less than 25 PSI (172 kPa).
• Water Temperature for test must be less than 100o F. (38o C).
• Limit test to 24 hours. After test, visually check system to be sure it is ready
for operation. Remove trap lid and retighten hand tight only.
NOTICE: These parameters apply to Sta-Rite equipment only. For
non-Sta-Rite equipment, consult manufacturer.
BEFORE WORKING
ON FILTER:
If filter clamp is
adjusted under pressure, tank will blow
off of base, causing
severe injury or major
property damage.

1. Stop pump.
2. Open air release
valve.
3. Release all pressure
from system.
GENERAL INFORMATION
Hazardous pressure. If filter is improperly disassembled or assembled, it will explode under pressure. To avoid danger of severe injury or
major property damage, always follow service instructions in this manual
(Pages 8 to 10) when working on filter.
Risk of explosion. Never operate this filter system at more than
50 pounds per square inch (50 PSI/345kPa) pressure!
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 correctly, clean water is
returned to the pool faster than the pool water is being contaminated. A typical pool installation 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 both 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. 13 and 14,
Page 14) are in place before operating filter. Clean air bleed periodically.
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 intervals.
NOTICE: Some pool disinfectants may clog filter media. To maximize media
life and filter cycle time, closely follow disinfectant manufacturer’s instructions when cleaning pool or filter.
On a new pool installation, we recommend:
1. Turn to Page 8 for instructions and disassemble the filter after the initial
cleanup.
2. Remove and hose down the element assembly to remove contaminants.

INSTALLATION - GENERAL
Installation of filter should only be done by qualified, licensed personnel.
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.
Never use pipe joint sealing compound on pipe and fittings that are plastic or
may come into contact with plastic. To seal threaded connections on PVC
pipe and fittings, use only Teflon tape, Plasto-Joint Stik* or Silastic RTV
#732**; 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 1-1/2” or 2” pipe to reduce pressure losses.
Before installing,
open filter to make
sure internal air
bleed tube and air
bleed filter (Key
Nos. 13 and 14,
Page 14) are in
place. Clean air
bleed periodically.
WARNING
NOTICE: Filter locations remote from pool are possible but may require larger
pipe to produce adequate flow through filter.
Check local codes if considering a remote installation.
Fittings restrict flow; for best efficiency use fewest possible fittings.
Keep piping tight and free of leaks: pump suction line leaks may cause
trapped air in filter tank or loss of prime at pump; pump discharge line leaks
may show up as dampness or jets of water.
Valves
A check valve installed between pool and filter outlet will prevent contaminants from draining back into pool.
NOTICE: A check valve between filter and pool will also prevent possible
backflow which could dislocate element from its seat.

head.
NOTICE: Air trapped inside the filter greatly increases the explosion hazard.
The air release valve allows you to get accumulated air out of the filter tank.
At startup, open the air release valve and make sure that it is running a solid
stream of water before putting the filter in service.
2. Start pump.
3. When a steady stream of water comes from air release valve, close valve.
4. After filter is operating, record filter pressure gauge 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 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 operational period will correct the condition.
Check pressure gauge; if pressure has risen more than 10 PSI (70kPa) above
startup pressure, remove and clean element.

FILTER CLEANING PROCEDURE
NOTICE: Keep track of filter operating pressure. When pressure reaches 10
pounds per square inch (PSI) (70kPa) above initial operating pressure, clean
filter element.
NOTICE: When sanitizing your pool using PHMB (polyhexamethylene biquanide based) sanitizers, 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 sanitizers will void the filter’s warranty.
NOTICE: If filter is used with a spa, soak element (see Step 2, “Special
Cleaning Instructions”) at each regular cleaning.
With hose, wash foreign material from inside of base. Try to avoid washing
debris into outlet port (see Figure 12).
NOTICE: Be sure inside surface of base is clean.
Washing Filter Element (See Figures 13 and 14):
1. Use a garden hose with straight flow nozzle to wash down filter element
(Figure 13).
2. Work from the top down; wash down all pleats. Wash between all pleats.

TROUBLESHOOTING GUIDE
A. Short Cycle:
2. Element cloth torn or punctured; replace element.
NOTICE: Time between cleanings will vary with
each installation and between different areas of the
country. The following causes and remedies are for
cycle times shorter than normal for your area.
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.
NOTICE: Some pool disinfectants may clog filter
media. To maximize media life and filter cycle time,
closely follow disinfectant manufacturer’s 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 10.
6. Heavy or improper application of powdered
chlorine or chlorine pills using a binder; see
“Special Cleaning Instructions”, Page 10.
7. Algae in pool - Apply heavy dose of chlorine or
algaecide as recommended by pool manufacturer. Continue until algae is controlled.
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 property damage, exactly follow instructions under
“Disassembly” and “Assembly” (Pages 8 and 9)!
1. Air bleed tube and/or tube filter not in position.
Exactly follow instructions in “Filter
Disassembly/Assembly Procedure”, Pages 8 and
9, and reinstall correctly.
2. Element cloth torn or punctured; replace element.
B. Low flow:
1. Element is plugged; see “Special Cleaning
Instructions”, Page 10.
2. Pipe blocked downstream from filter; remove obstruction.
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 information.
3. Filter element is not seated properly in filter base;
follow instructions under “Filter
Disassembly/Reassembly”, Pages 8 and 9, and
reposition properly.
4. Filter is plumbed backwards and element cloth is
