IMPORTANT SAFETY INSTRUCTIONS
When installing and using electrical equipment, basic safety precautions should always be followed,
including the following:
SAVE THESE INSTRUCTIONS
1. READ AND FOLLOW ALL SAFETY INSTRUCTIONS.
2. To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at
all times.
3. Risk of electrical shock. Connect only to a
grounding type receptacle protected by a ground-fault circuit-interrupter (GFCI). Contact a qualified electrician if you
cannot verify that the receptacle is protected by a GFCI.
4. Do not bury cord. Locate cord to minimize abuse from lawn
mowers, hedge trimmers, and other equipment.
5. To reduce the risk of electrical shock,
replace a damaged cord immediately.
6.
To reduce the risk of electrical shock, do not
use an extension cord to connect unit to electrical supply; provide a properly located outlet.
7. Permanent pumps are for use with permanently installed pools and may also be used with hot tubs and
spas if so marked. Do not use with storable pools. A permanently installed pool is constructed in or on the ground or in a
building such that it cannot be readily disassembled for storage. A storable pool is constructed so that it may be readily
disassembled for storage and reassembled to its original integrity.
8. Storable pool pumps are for use with storable
pools only. Do not use with permanently installed pools. A
storable pool is constructed so that it is capable of being
readily disassembled for storage and reassembled to its original integrity. A permanently installed pool is constructed in
or on the ground, or in a building, such that it cannot be readily disassembled for storage.

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.
NEVER test this filter with compressed air.
Do not operate filter at water temperatures
above 95°F (35°C).
NEVER operate this filter system at more than
50 pounds per square inch (50 PSI/345 kPa)
pressure!
Plug system into electrically isolated, Ground
Fault Circuit Interrupter protected circuit
ONLY!
• 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.
• Keep pool water pH at recommended level (7.2 to
7.6) to avoid irritation to eyes and skin.
• The Hi-Rate Sand Filter System is designed for use
with above ground swimming pools only.
• Use only #20 Silica sand with a screen mesh of .45
to .55mm. Use of other sands will reduce filter
performance.
To reduce risk of electric shock, install
pump at least 10 feet from the inside wall of the pool.
Do not use an extension cord.
INSTALLATION
Trap to Pump Assembly:
Using four 5/16” cap screws, flat washers and lockwashers, mount trap to pump body; be sure to install gasket
between trap and pump body. Tighten cap screws to 80
inch-lbs
(92 cm-kg) torque; do not overtighten.
Filter Mount Must:
• Provide weather and freezing protection.
• Provide space and lighting for easy access for routine
maintenance. (See Table I and Figure 1, Page 4, for
space requirements.)
• Be on a reasonably level surface and provide ade-
quate drainage.
• Be as close to pool as possible to reduce line loss
from pipe friction.
• Be solid – level– rigid – vibration free.
• Be installed so that trap suction inlet is below pool
water level at all times. This allows pump to prime.
• Have adequate ventilation to prevent motor
overheating.
Piping:
• Use teflon tape or Plasto-Joint Stik1on all male connections of plastic pipe and fittings except unions.
DO NOT use pipe compounds on plastic pipe; it
will cause the pipe to crack. Do not use sealant or
tape on unions – assemble them dry and hand tight.
• Do not damage union sealing surfaces and “O” Rings.
• Support pipe independently to prevent strains on filter
and valve.
• Use 1-1/2 or 2" pipe to reduce pressure losses as
much as possible. If flex hose is used, use the type
with smooth internal walls.
• 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.
• When unions are provided, use as follows for leak
free connections:
1. O-Ring and sealing surfaces must be clean.
2. Assemble hand tight only (no wrenches).
3. No pipe compound or teflon tape on unions.
Valves:
• For servicing filter system and for cleaning pump trap,
install ball or gate valves
A. Between pump trap and pool skimmer, and
B. Between selector valve and return pipe to pool.
• A check valve installed between filter and heater will
prevent hot water from backing up into filter and deforming internal components.
• Use care before assembly not to damage union sealing surfaces or O Ring.
Wastewater:
• Be sure all provisions for waste water disposal meet
applicable local, state or national codes. 100 gallons
(379 liters) or more of pool water will be discharged
during filter backwashing. Do not discharge where
water will cause flooding or damage.

Filter Setup
Assembly: See Figures 2 through 5 for filter assembly.
Loading Sand Media
1. To keep sand out of collector assembly, place plastic
sand shield over top of collector tube before pouring
sand into filter (See Figure 5).
2. To support laterals and prevent lateral breakage during loading, fill tank about half full of water before
loading sand.
3. Pour sand into filter tank. See “Recommended Sand
Grades”, Page 4, for correct type and quantity of
sand to use.
NOTICE: Make sure gasket area on top of tank is
free of sand before installing valve and clamp.
4. Before installing valve, double-check that correct
quantity of sand has been loaded (see Page 4).
5. Remove plastic sand loading shield and keep for future use.
Valve Installation:
See Figures 6, 7, and 8
1. Install O-Ring on valve flange; make sure O-Ring is
clean, dry, and has no nicks, tears, or scrapes.
2. Make sure tank and valve flanges are clean and free
of sand; put valve on top of tank. Vertical pipe of collector assembly inserts into base of valve.
3. Install clamp; make sure knob is positioned for easy
access for filter maintenance. Valve port labeled
“PUMP” should point toward pump.
4. Tighten clamp knob until clamp ends (under bolt) are
1/4" (6mm) apart. Tap around outside of clamp with
a mallet to help seat clamp.
Hazardous pressure. Clamp will not
hold unless it is seated properly! DO NOT START
PUMP until clamp ends are 1/4" (6mm) apart or
less.
5. If clamp will not pull up to 1/4" (6mm) gap, wait
15-30 minutes and retighten. Tap clamp gently with
mallet to help seat clamp.
6. Connect pipe from pump discharge to valve port labeled “PUMP”; use union half provided. Assemble
union as follows for leakfree operation:
A. O-Ring and sealing surfaces must be clean.
B. Assemble hand tight only (no wrenches).
C. NO pipe compound or teflon tape on unions.
7. Complete all plumbing connections (see Page 5 for
piping requirements).
A. Pipe from valve RETURN port to pool return.
B. Pipe from valve WASTE port to waste.
C. Suction piping from pool to trap inlet on pump.
8. System is ready for startup.
NOTICE: If there are leaks from beneath valve/clamp
area, STOP PUMP, release all pressure, remove
clamp and valve and clean sealing surfaces.
B. Insert assembly
into top of
filter tank.

ELECTRICAL
Risk of electrical shock.
Plug pump into a
grounded, GFCI-protected 115
Volt circuit only. Incorrect voltage can cause fire or seriously
damage motor and voids warranty. Protect cord from water
and physical damage.
GFCI tripping indicates
an electrical problem. If
GFCI trips and will not reset,
have a qualified electrician inspect and repair electrical
system.
Risk of electrical
shock. Unplug
motor before servicing or repairing pump or motor.
Wiring:
Install a Ground Fault Circuit Interrupter (GFCI) in circuit; it will sense a short-circuit to ground and disconnect power before it becomes dangerous to pool users.
For size of GFCI required and test procedures for
GFCI, see manufacturer’s instruction.
In case of power outage, check GFCI for tripping (which
will prevent normal water circulation). Reset if necessary.
Match circuit breaker size to Table III, Page 8.
• Do not modify cord, plug, or receptacle. If an existing
circuit must be used and the receptacle and plug do
not match exactly, consult a licensed electrician.
• Do not use an extension or drop cord with this system; it could cause a fire hazard or low voltage problems. Wet cords cause shock hazards. Extension
cords can easily become cut or frayed and dangerous when placed across yard areas or walkways.
Voltage:
Voltage at motor must be not more than 10% above or
below motor nameplate rated voltage or motor may
overheat, causing overload tripping and reduced component life. If voltage is less than 90% or more than
110% of rated voltage when motor is running at full
load, consult power company.

Hazardous pressure. To avoid explosion and possible severe or fatal injury, filter system pressure must not exceed 50 PSI (345 kPa)
under any circumstances. NEVER test this filter
system with compressed air; never operate system
with water temperature above 95° F (35° C).
To prevent equipment damage and possible injury, turn pump OFF before changing valve
position.
NOTICE: Do not add chemicals directly into the pool
skimmer. Adding undiluted chemicals may damage
equipment and void warranty.
1. Open system valves and make sure pump is filled
with water.
Make sure pool water level is above skimmer or the
suction outlet.
2. With pump OFF, set valve to ‘BACKWASH’ position.
3. Start pump, circulating water backwards through filter to waste.
4. Backwash until water runs clear (3-5 minutes).
5. Stop pump; set valve to ‘RINSE’ position.
6. Start pump; run pump for one minute.
7. Stop pump; set valve to ‘FILTER’ position.
8. Filter is now ready for service.
9. Record clean starting filter pressure gage reading
as a reference.
10. When pool is first filled, backwash once a day until
pool water is sparkling clear. After that, backwash
when pressure gage shows 5 to 7 PSI (34.5 to 48
kPa) higher than starting pressure.
MAINTENANCE
General:
• Wash outside of filter with a mild detergent and water.
Rinse off with hose.
NOTICE: DO NOT use solvents to clean filter; solvents may damage plastic components in system.
• Inspect sand bed at least once a year to remove foreign material which has not been backwashed out of
system.
NOTICE: When the sand bed gets hard and crusty
on top, remove all the old sand and replace it with
new sand.
Weekly Pool Equipment Inspection:
1. Check pressure during operation. When pressure is
5 to 7 PSI (34.5 to 48 kPa) higher than initial operating pressure, backwash filter (see instructions under
“Startup/Operation”).
2. Except during hot weather with heavy swimmer loads,
operating filter 6 to 12 hours per day should be sufficient. Carefully monitor water chemical balance and follow recommendations of your local pool professional.
Water Maintenance
• Keep water level at least two inches above bottom of
skimmer opening when system is not in operation.
Failure to do so can allow air to enter system, causing pump to lose prime and filter to entrap air.
• Maintain pH at 7.2 to 7.6 in pool.
To prevent damage to system components,
keep water temperature below 95° F (35° C) at
all times.
Vacuum Pool:
1. Fill vacuum hose by submerging in water from one
end to the other.
2. To vacuum, insert hose into skimmer suction mani-
fold or into vacuum line in pool wall. See instructions
provided by pool builder or pool manufacturer. Start
pump, making sure it is primed and pumping.
3. After vacuuming, clean pump trap to remove accu-
mulated debris, then check filter pressure gage. If
reading is 5 to 7 PSI (34.5 to 48 kPa) higher than initial operating pressure, backwash filter
Lower or Drain Pool
(See Figure 10, Page 10)
1. Turn pump ‘OFF’; set valve handle to ‘WASTE’.
2. Use vacuum cleaner hose and head.
3. Start pump; run until pool is lowered to desired level.
4. Turn pump ‘OFF’; set valve handle to ‘FILTER’.
5. Start pump.

STORAGE/
WINTERIZING
Pool chemicals may give off corrosive
fumes. Store chemicals away from system in a well
ventilated area.
NOTICE: Allowing water to freeze will damage filter and
void warranty. If antifreeze is needed, use propylene glycol; it’s plastic compatible and non-toxic. Follow manufacturers instructions. Do not use ethylene glycol based
anti -freeze – it’s toxic and it may damage plastic components.
1. Open all system valves. Set multiport valve at ‘WIN-
TERIZE’ to allow air passage to all ports (Figure 11).
2. Remove drain plug from filter.
3. Drain filter tank completely and replace drain cap
(Figure 12).
4. Cover with plastic or tarpaulin to protect from
weather.
5. Remove drain plugs from pump.
6. Protect from freezing.
Startup for Winterized Equipment:
1. Remove any temporary weather protection placed
around system for shutdown.
2. See “Startup”, Page 8, for reactivation of the filter.
3. Inspect all electrical wiring to pump for damage or
deterioration over the shutdown period. Have a qualified serviceman repair/replace wiring as needed.
Inspect and tighten all watertight connections.
4. Open all valves in suction and return piping.
5. Remove any winterizing plugs in system.
6. Drain all winterizing chemicals (if used) from system;
flush system.
7. Close all drain valves and replace all drain plugs in
system.
8. Fill pool with water to proper level (see pool maufac-
turer’s instructions).
Drain Fitting Installation/Removal
NOTICE: If pool is above height of filter, first close
valves in pump suction and return lines to prevent
draining pool. If there are no shutoff valves installed,
disconnect suction and return lines and raise ends
above pool water level.
1. Installation: See Figure 12.
2. To Drain Filter:
A. Remove drain cap. Lateral tube should remain in
place inside drain opening to prevent sand from
draining out.
B. Open union coupling on backwash port of Multi-
Port valve. This will allow air into filter and allow
water to drain from filter tank.
C. Replace cap when tank is empty.
3. Removing Sand From Filter:
A. Remove both drain cap and slotted lateral tube
(see Figure 12). Sand and water will drain from
tank.
B. To completely flush filter tank of sand,
remove top clamp and multiport valve and flush
the inside of the tank with a hose.
C. Thoroughly clean sand from all parts and from
tank drain opening before reassembling drain fitting.
