before operating or testing equipment.
4. DO NOT pressure test with compressed air!
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 equipment manufacturer.
BEFORE WORKING
ON FILTER:
If filter clamps are
adjusted or removed
under pressure,
tank may explode,
causing severe injury or
major property damage.
1. Stop pump.
2. Open air release
valve.
3. Release all pressure
from system.
BEFORE WORKING
ON PUMP OR MOTOR
Filter pumps require
hazardous voltage
which can shock, burn,
or cause death.
3
Disconnect power
to motor at main
circuit breaker.
Discharge motor
capacitor to ground.
GENERAL INFORMATION
• 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 diatomaceous earth (DE) filter system in place and operating correctly, clean water is returned to the pool faster than 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.
• DO NOT use more than the recommended amount of DE in your filter. To
do so can cause a buildup of DE and "bridging" between the elements
which will plug the filter.
If filter is improperly disassembled or assembled, it can explode under
pressure! To avoid danger of severe injury or major property damage,
always follow service instructions in this manual when working on filter!
Hazardous pressure.
Can cause severe
injury or major
property damage
from tank blow up.
Release all pressure
and read instructions
before working on filter.
NEVER operate this filter system at more than 50 pounds per square
inch (50 PSI/345kPa) pressure! Be sure filter pressure gauge operates
when system is operating. If pressure gauge is damaged or does not work,
replace it.
Purge all air from system before operating system. NEVER operate filter
with air trapped inside.
• On a new pool installation, we recommend:
1. Disassemble the filter after the initial cleanup.
To prevent severe injury or major property damage, exactly follow “Filter
Disassembly/Assembly Procedure” on Page 8.
2. Remove and hose down the module to remove contaminants.
• It is a good idea to remove the module once a year and soak it in a filter
cleaning solution to remove accumulated body oils, etc.; see Page 11,
“Special Cleaning Instructions”.
• Cleaning interval is based on pressure differential, not on length of time filter is operated. Different water conditions will have different normal cleaning intervals. If backwashing filter is not possible, use “Module Cleaning
Procedure”, Page 10, at regular intervals to clean filter.
• Check local codes for restrictions on backwash to waste piping, separation
tank requirements and spent D.E. disposal requirements.
4
INSTALLATION
Installation of filter should only be done by qualified, licensed personnel.
Filter mount must:
• Provide weather and freezing protection.
• Provide space and lighting for easy access for routine maintenance. (See
Figure 1 and Table II, Page 6, for space requirements.)
• Be on a reasonably level surface and provide adequate drainage.
• Be as close to pool as possible to reduce line loss from pipe friction.
Piping:
• Piping must conform to local/state plumbing and sanitary codes.
• Use Teflon tape or Plasto-Joint Stik' on all male connections of plastic pipe and
fittings. DO NOT use pipe compounds on plastic pipe; it will cause the pipe
to crack. Do not use sealant on unions—assemble them dry and hand tight.
• Support pipe independently to prevent strains on filter or valve.
• Use 2" (51mm) pipe to reduce pressure losses as much as possible.
NOTICE: Filter may be located away from pool, but for adequate flow larger
pipe may be needed. Check local codes for 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.
• NOTICE: Overtightening can crack filter ports.

NOTICE: Use of valves
other than those listed
above could cause
reversed water flow
through filters and
damage to internal filter components.
• A check valve installed ahead of filter inlet will prevent contaminants from
draining back into pool.
• A check valve installed between filter and heater will prevent hot water
from backing up into filter and deforming internal components.
• For installation allowing backwashing, install Sta-Rite Two Position Slide
Valve or Multiport Selector Valve with filter. See Table I. If you intend to
clean your filter according to “Module Cleaning Procedure”, Page 10, no
slide or multi-port valve is required. See Figures 1 and 2, Page 6, for correct
water flow when connecting pipe.
• Filter ports and valve ports are furnished with union connections.
DO NOT use pipe sealants on union collar (nut).
• Use care before assembly not to damage union sealing surfaces or O-Ring.
• To allow recirculation during precoat (if precoat pot is used), install a recirculation line with shut-off between pad return line and pump suction.
Electrical
• All wiring, grounding and bonding of associated equipment must meet local
and/or National Electrical Code standards.

MODULE CLEANING
PROCEDURE
Hazardous pressure.
Can cause severe
injury or major
property damage
from tank blow up.
Release all pressure
and read instructions
before working on filter.
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 in a convenient place).
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 required flow.

WINTERIZING
Explosion hazard. Purging the system with compressed air can
cause components to explode, with risk of severe injury or death to anyone
nearby. Use only a low pressure (below 5 PSI), high volume blower when air
purging the pump, filter, or piping.
NOTICE
The filter outlet piping will not empty
through the filter drain. Make sure that
the outlet piping has a separate drain for
winterizing.
NOTICE: Protect the filter from freezing. Allowing the filter to freeze will damage it and will void the warranty.
1. Clean the filter according to instructions (Page 10) before winterizing. Do
not winterize with DE precoat on cartridge or with residual in tank.
2. Stop the pump.
3. Open the air release valve; open all the system valves.
4. Remove the drain plugs from the trap, pump, and filter.
5. Drain the system piping.
A. Gravity drain system as far as possible.
B. Protect areas which retain water with non-toxic propylene glycol
antifreeze (“RV antifreeze”).
6. Loosen the union nuts (if used) to drain all water from the filter interior.
Leave these nuts loose until the system is restarted.
7. Disassemble the filter (follow instructions under “Filter Disassembly”, Page
8). Remove the filter module and store it in a warm, dry area. Be sure to
store the cartridge where it will not be in sunlight.
8. Be sure to allow any water trapped in the tank to drain out.
