ADANGER: ELECTROCUTION
OR ELECTRICAL SHOCK RISK.
DISCONNECT ELECTRICITY BEFORE
WORKING ON PUMP, OR SHOCK, BURN
OR ELECTROCUTION CAN RESULT.
Always disconnect pool pump power at the circuit breaker
before servicing the pump. Death or serious injury to
service people, pool users or others due to electric shock
could result from failure to avoid the high danger risk.
ADANGER: For continued protection against possible
electrical shock, this unit is to be mounted to the base in
accordance with the installation instructions.
NOTE: Always turn o󰀨 all power to the pool pump before
installing the cover or working on any suction outlet.
NOTE: This pump operates with electrical voltage, and
can generate both vacuum and pressure in the water
system. When properly wired and plumbed, this pump
will operate in a safe manner.
ACAUTION: This pump is for use with permanently
installed pools and may also be used with hot tubs and
spas. Do not use with storable pools unless the pump
is protected by a factory-installed double-insulated
enclosure. 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.
AWARNING: To reduce the risk of electrical shock,
replace any damaged electrical cord immediately.
AWARNING: Never work on the pump while it is
running or the power is still connected. High voltage
and cause serious or fatal injury. A suitable ground
fault interrupter (GFCI) should always be installed at
the power supply source of this unit. Article 681-31 of
the NEC requires that a GFCI be used if this pump is
used with a storage pool. Be sure to ground the motor
before connecting to electrical AC power source. Failure
to ground the motor can cause serious or fatal electrical
shock hazard. DO NOT ground to a gas supply pipe line.
AWARNING: A pool or spa pump must be installed
by a qualied pool and spa service professional in
accordance with the National Electrical Code and
all applicable local codes and ordinances. Improper
installation may cause and electrical hazard which could
result in death or serious injury to pool users, installers,
or others due to electrical shock, and also cause
property damage.
AWARNING: Pumps are not a substitute for properly
installed and secured pool drain covers. An ANSI/ASME
A112.19.8 approved anti-entrapment drain cover must
be used for each drain. Pools and spas should utilize a
minimum of 2 drains per pump. If a drain cover becomes
loose, broken, or is missing, close the pool or spa
immediately and shut o󰀨 the pump until an approved
anti-entrapment drain cover is properly installed with
the manufacturer's supplied screws.
NOTE: Always turn o󰀨 all power to the pool pump before
installing the cover or working on any suction outlet.
ACAUTION: Elevated water temperature can
be hazardous. The U.S. Consumer Product Safety
Commission has these guidelines:
1. Spa water temperatures should never exceed 104°F
(40°C). A temperature of 100°F (38°C) is considered
safe for a healthy adult. Special caution is suggested
for young children.
2. Drinking of alcoholic beverages before or during spa
or hot tub use can cause drowsiness which could
lead to unconsciousness and subsequently result in
drowning.
3. Pregnant Women Beware! Soaking in water over
102°F (39°C) can cause fetal damage during the rst
three months of pregnancy resulting in the birth of a
brain-damaged or deformed child.
4. Before entering the spa or hot tub, users should
check the water temperature with an accurate
thermometer; spa or hot tub thermostats may err
in regulating water temperatures by as much as 4°F
(2.2°C).
5. Persons with a medical history of heart disease,
circulatory problems, diabetes, or blood pressure
problems should obtain a physician’s advice before
using pools or hot tubs.
6. Persons taking medications which induce
drowsiness, such as tranquilizers, antihistamines,
or anticoagulants, should not use spas or hot tubs.
AWARNING: Pump suction is hazardous and can
trap and drown or disembowel bathers. Do not use or
operate swimming pools, spas, or hot tubs if a suction
outlet cover is missing, broken, or loose.
ADANGER: Hazardous suction can
trap hair or body parts, causing severe
injury or death. Do not block suction.
AWARNING: Risk of Electric Shock. Connect only
to a branch circuit protected by a ground-fault circuit-
interrupter (GFCI). Contact a qualied electrician if you
cannot verify that the circuit is protected by a GFCI. The
unit must be connected only to a supply circuit that is
protected by a ground-fault circuit-interrupter (GFCI).
Such a GFCI should be provided by the installer and
should be tested on a routine basis. To test the GFCI,
push the test button. The GFCI should interrupt power.
Push the reset button. Power should be restored. If
the GFCI fails to operate in this manner, the GFCI is
defective. If the GFCI interrupts power to the pump
without the test button being pushed, a ground current
is owing, indicating the possibility of an electric shock.
Do not use this pump. Disconnect the pump and have the
problem corrected by a qualied service representative
before using.

3. IMPORTANT SAFETY
INSTRUCTIONS
Entrapment Prevention
ADANGER: DO NOT BLOCK SUCTION.
ADANGER: Hazardous suction can
trap hair or body parts, causing severe
injury or death. Do not block suction.
ADANGER: Hazardous suction can
trap hair or body parts, causing severe
injury or death. Do not block suction.
SUCTION HAZARD. Suction can cause serious injury or
death. Do not use this pump for wading pools, shallow
pools, or spas containing bottom drains, unless pump is
connected to at least two functioning suction outlets.
AWARNING: Pump suction is hazardous and can
trap and drown or disembowel bathers. Do not use or
operate swimming pools, spas, or hot tubs if a suction
outlet cover is missing, broken, or loose.
The following guidelines provide information for pump
installation that minimizes the risk of injury to users of
pools, spas, and hot tubs:
Entrapment Protection
The pump suction system must provide protection against
the hazards of suction entrapment.
Suction Outlet Covers
All suction outlets must have screw-fastened covers
installed. All suction outlet (drain) covers must be
maintained. Drain covers must be listed/certied to the
latest published edition of ANSI/ASME A112.19.8 (ANSI/
APSP-16, 2011). They must be replaced if cracked,
broken, or missing.
Number of Suction Outlets Per Pump
Provide at least two hydraulically-balanced main drains,
with covers, as suction, for each circulating pump suction
line. The centers of the main drains (suction outlets) on
any one suction line must be at least 3 ft (.9 m) apart,
center to center.
The system must be built to include at least two suction
outlets (drains) connected to the pump whenever the pump
is running. However, if the two main drains run into a single
suction line, the single suction line may be equipped with a
valve that will shut o󰀨 both main drains from the pump. The
system shall be constructed such that it shall not allow for
separate or independent shuto󰀨 or isolation of each drain.
More than one pump can be connected to a single suction
line as long as the requirements above are met.
Water Velocity
The maximum water velocity through the suction tting
or cover for any suction outlet must be 1.5 ft (.5 m) per
second, unless the outlet complies with the latest published
edition of ANSI/ASME A112.19.8 (ANSI/APSP-16, 2011),
the standard for Suction Fittings For Use in Swimming and
Wading Pools, Spas, Hot Tubs, and Whirlpool Bathtub
Applications. In any case, do not exceed the suction
tting’s maximum designed ow rate.
If 100% of the pump’s ow comes from the main drain
system, the water velocity in the pump suction hydraulic
system must be 6 ft (1.8 m) per second or less, even if one
main drain (suction outlet) is completely blocked. The ow
through the remaining main drain(s) must comply with the
latest published edition of ANSI/ASME A112.19.8 (ANSI/
APSP-16, 2011), the standard for Suction Fittings For Use
in Swimming and Wading Pools, Spas, Hot Tubs, and
Whirlpool Bathtub Applications.
Testing and Certication
Suction outlet covers must have been tested by a nationally-
recognized testing laboratory and found to comply with the
latest published edition of ANSI/ASME A112.19.8 (ANSI/
APSP-16, 2011), the standard for Suction Fittings For Use
in Swimming and Wading Pools, Spas, Hot Tubs, and
Whirlpool Bathtub Applications.
Fittings
Fittings restrict ow; for the best e󰀩ciency, use the fewest
possible ttings (but at least two suction outlets).
Avoid ttings that could cause an air trap.
Pool cleaner suction ttings must conform to applicable
International Association of Plumbing and Mechanical
O󰀩cials (IAPMO) standards.
SAVE THESE INSTRUCTIONS.

4. OVERVIEW
AWARNING: Failure to operate your lter system,
or inadequate ltration, can cause poor water clarity
obstructing visibility in your pool. Poor water clarity may
obscure objects while swimming which, while swimming
and diving, could cause serious personal injury or death.
Never swim in a pool with poor water clarity.
AWARNING: This lter operates under high pressure.
When any part of the circulating system (e.g., clamp,
lter, valves, etc.) is serviced, air can enter the system
and become pressurized. Pressurized air can cause
the lid or control valve to separate which may result in
serious injury, death, or property damage. To avoid this
potential hazard, follow these instructions.
Before any service to the circulating system (repositioning
valves, beginning the assembly, disassembly, clamp
adjustment, etc.):
a. Turn off electricity going both to the pump
off and to any automatic controls to avoid
accidental system start-up during servicing;
b. Open manual air relief valve;
c. Wait until the pressure gauge reads zero (0) to
ensure all pressure is gone.
1. When, or if, installing the filter clamp, follow the filter
valve and clamp installation instructions exactly.
2. Follow the system restart instructions exactly after
service on the circulation system is complete.
3. Maintain circulation system proactively. Damaged
and worn parts must be replaced immediately (e.g.,
clamp, pressure gauge, relief valve, O-rings, etc.).
4. Mount the filter properly and position it according to
all provided instructions.
Filter
The sand lter is designed to last for years of use when
maintained properly. Its purpose is to extract suspended
particles (dirt) from the pool water to keep the water clear.
A special lter sand is used to trap and collect the particles.
The ltering action occurs as the water ows through the
unit, and the particles are trapped in the sand bed which
form the lter.
In terms of layout, water enters through a valve on the
top of the lter and then passes evenly though the lter.
The ltered water then exits through the bottom side of the
lter, up through the stand pipe, through a valve on the top,
and then back into the pool though piping or hoses.
In terms of capacity, please ensure the volume of water
cleaned in every 24-hour cycle is, at minimum, at least
double the total volume in the pool so proper cleaning can
occur.
After time, enough particles will have collected in the lter
sand to impede the easy ow of water though it and this
resistance will cause the lter pressure to build to such a
point that the lter needs cleaning (purging). That process
is called backwash.
The backwash procedure reverses the ow of water
through the lter to ush out the particles and discharge
them, not back into the pool, but into a waste line. A valve
on the unit top is set to BACKWASH. This is a manual
procedure. After running the BACKWASH cycle, reset the
value to FILTER manually to resume normal ltration.
The sand lter, while designed to remove particles and/or
other debris suspended in the water, does not adjust the
pH level or the bacterial count.
Sanitation and pH balancing are specialized and important
areas that are covered with other tools, equipment and
knowledge and as such are beyond the scope of the
manual. Roughly speaking, pH level should be in the range
of 7.2~7.6, and chlorine about 1~2 ppm, but much more
goes into water chemistry than this. Check the local codes
and with pool service specialists for required instruction.
Constant Speed Pump Models
This above-ground pool centrifugal pump is designed to
operate for years with proper maintenance. The pump
body, trap with basket, di󰀨user and impeller are made from
high quality thermoplastic materials. These materials are
made using corrosion-resistant materials. When installed,
operated and maintained in accordance with these
instructions, your pump will provide years of service.
These pumps are driven by an electric motor which is
directly attached to an impeller. When the electric motor
turns, the impeller turns too, moving water from the trap
inlet to the outlet for water circulation. The trap basket stops
debris from going into the pump to protect the impeller.
It has a transparent lid cover which can be opened for
cleaning out the trap.
Dual-Speed Pump Models
Some of the pumps feature both high-speed and low-
speed settings. At low speed, the pump runs at half of
the high speed rate and thus has a di󰀨erent performance
curve. In low-speed mode, the electrical energy savings
are 60%, based on an equal amount of circulated water.
Switch the motor to low speed for quiet operation and
electrical cost savings if circulation turnover time is not a
critical consideration. Expect that minor adjustments may
be required with the automatic chlorine dispenser, the
skimmers and the heater due to the lower ow. Refer to
the manual as necessary.
High-speed mode is ideal for vacuuming the pool, quick
ltering action, priming the system, and to keep up with
heavy bathing use.

AWARNING: Blockage of suction ttings can cause
serious or fatal injury due to drowning. To reduce the
risk of injury, do not permit children to use this product.
5. INSTALLATION
AWARNING: Chemical fumes and/or spills can cause
serious corrosion to the lter and pump structural
components. Structurally-weakened components can
cause lter, pump or valve attachments to separate and
could cause serious bodily injury or property damage.
AWARNING: The system's centrifugal pump operates
with electrical voltage, and can generate both vacuum
and pressure in the water system. When properly wired
and plumbed, this pump will operate in a safe manner.
AWARNING: Never work on the pump while it is
running or power is still connected. High voltage can
cause serious or fatal injury. A suitable ground fault
interrupter (GFCI) should always be installed at the
power supply source of this unit. Article 681-31 of the
NEC requires that a GFCI be used if this pump is used
with a storage pool. Be sure to ground the motor before
connecting to electrical AC power source. Failure to
ground the motor can cause serious or fatal electrical
shock hazard. DO NOT ground to a gas supply pipe line.
ADANGER: High-pressure release
from the sand lter can cause severe
injury or major property damage due
to parts ying open or apart. Release
all pressure in the sand lter before
doing any work on it. For example, avoid
adjusting the lter clamp under pressure
as that can cause it to separate resulting
in serious injury or property damage.
Pump
1. Only qualified, licensed personnel should install
pump and wiring.
2. Electrical Contractors Please Note: All 115VAC 60Hz
pumps must be wired to the main power supply
through an approved and correctly-rated contactor.
3. Allow for gate valve in suction piping.
Pump suction and discharge connections have molded
in thread stops,do not try to screw pipe in beyond these
stops.
Pump Mount
• Must be on a solid, level, rigid and vibration-free
surface.
• Ensure pump suction inlet height to be as close to
pool water level as possible. Ensure the use of a
short, direct suction pipe, to reduce friction losses.
• Avoid installing the pump above the water level.
Suction lifts of more than 6" (152 mm) will cause
very long priming times, and potentially damage the
pump.
• Allow for gate valves in the suction and discharge
piping. Ensure adequate floor drainage to prevent
flooding.
• Protect from excess moisture.
• Ensure adequate access for servicing the pump,
filter, and piping.
Packaging
A hose barb kit and union kit are included and needed to
make the connections.
UNION KIT HOSE BARB KIT
Figure 1. Connection Kits
Pump Assembly Steps
1. The system should be installed as close as possible
to the swimming pool and preferably at a level of 20"
(0.5 m) below the level of the water in the swimming
pool. It should be preferably in a dry, well-ventilated
area away from direct sunlight and on a hard, level
surface. Make sure there is drainage available at
the place where the filter is to be installed. Give
consideration to:
a. Drainage far away from pump.
b. Ventilation of the pump motor.
c. Access for future servicing and winterizing.
2. Bolt the pump onto the platform.
3. Connect the suction and discharge pipes to the outlet
and inlet of the swimming pool.
4. The pump motor must be wired in accordance with
the wiring diagram supplied with the motor using
the right voltage. Wiring the motor with the incorrect
voltage will cause damage to the motor. Such
damage will not be covered under warranty.
5. Install, ground and bond wire according to local or
National Electrical Code requirements.
6. Permanently ground the motor. Locate the ground
terminal located on the rear side of the motor and
use the wire gauge and type required by code to
connect the motor ground terminal to the electrical
service ground. On cord-connected circuits, check
for proper grounding.

9
7. Bond permanently-wired pumps. The National
Electrical Code requires that the motor be electrically
bonded to the appropriate permanently-installed
pool or spa/hot tub structure using a solid copper
conductor no smaller than No. 8 AWG. The bonding
wire should be connected from the accessible wire
connector on the motor shell to all metal parts of the
swimming pool, spa or hot tub structure and to all
electrical equipment, metal conduit and metal piping
within 5 feet of the inside walls of a swimming pool,
spa or hot tub. A grounding lug is provided on the
exterior of the motor shell for this purpose.
Filter Assembly
Common tools such as screwdrivers, wrenches, and
consumables like pipe sealant for plastic adapters are
required for the installation and service of the sand lter.
See the schematic for layout information, Figure 4.
Pouring Sand Filter Sand Media
1. The filter should be placed on a level concrete slab,
very firm ground, or equivalent. Locate the filter
so that the piping connections, control valve are
convenient and accessible for operation and service.
2. Filter sand media is loaded through the top opening
of the filter as follows:
a. Loosen the flange clamp and remove the filter
control valve (if previously installed).
b. Cap the internal pipe with a plastic cap to prevent
sand from entering it.
c. We recommend filling the tank approximately 1/2
full with water to provide a cushioning effect when
the filter sand is poured in. This helps protect the
under-drain laterals from excessive shock.
d. Carefully pour in the correct amount and grade
of filter sand. (Be sure the center pipe remains
centered in opening.) When done, the sand
surface should be leveled and should come to
about the middle of the filter tank. Remove the
plastic cap from the internal pipe.
Filter Control Valve Assembly
1. Assemble the filter control valve in the filter tank.
a. Insert the filter control valve (with O-ring in place)
into the tank neck, taking care that the center
pipe slips into the hole at the bottom of the valve.
b. Place two plastic clamps around the valve flange
and tank flange and tighten just enough so that
the valve may be rotated on the tank for final
positioning.
c. Carefully screw the pressure gauge (with O-ring
in place) into the tapped hole in the valve body.
Do not over-tighten.

6. START-UP
AWARNING: NEVER run the pump dry! Running
the pump dry may damage seals, causing leakage and
ooding! Fill the pump with water before starting the
motor. These pumps cannot self-prime.
AWARNING: Do not block pump suction! To do so
with body may cause severe or fatal injury. Children
using pool must ALWAYS have close adult supervision.
CAUTION: Before removing the lid:
• STOP THE PUMP before proceeding.
• CLOSE THE GATE VALVES in the suction and
discharge pipes.
• RELEASE ALL PRESSURE from the pump and
piping system.
• NEVER tighten or loosen screws while the pump is
in operation.
Priming Pump
1. Release all air from the filter and piping system (see
filter instructions below).
2. In a flooded suction system (water source higher
than the pump) the pump will prime itself when the
suction and discharge valves are opened.
3. If the pump is not in a flooded suction system,
unscrew and remove the trap cover; fill the trap and
pump with water.
4. Clean and inspect the O-Ring; re-install it on the trap
cover.
5. Replace the trap cover on the trap; turn clockwise to
tighten the cover.
NOTE: Tighten the trap cover by hand only. The pump
should prime now. Priming time will depend on vertical
length of suction lift and horizontal length of suction
piping.
Initial Start-Up
NOTE: During initial clean-up of the pool water, it may
be necessary to backwash more frequently due to a
possibly unusually-heavy initial dirt load in the water.
AWARNING: Always turn the pump o󰀨 before
changing valve positions. Changing valve positions
while the pump is running can damage the control valve,
which may cause serious injury or property damage.
1. Make sure the correct amount of filter media (specified
sand) is put into the tank and that all connections
have been connected and secured.
2. Depress the multiport valve handle and rotate it
CLOCKWISE (right) to the BACKWASH position.
Always depress the valve handle before turning it to
prevent damage to the multiport valve seal.
3. Prime and start the pump according to the pump
priming instructions above. Make sure all suction and
return lines are open to allow the filter tank to fill with
water.
NOTE: Tighten the trap cover by hand only. Pump should
prime now. Priming time will depend on vertical length of
suction lift and horizontal length of suction piping.
4. Once water is flowing out of the waste line, run the
pump for at least 1 minute. An initial backwash of
the filter is recommended to remove any impurities or
fine sand particles in the sand media.
5. Turn the pump off and set the multiport valve to the
RINSE position. Start the pump and operate it until
the water in the view glass is clear, about 30 seconds
to 1 minute. Turn the pump off and set the valve to
FILTER position and restart the pump. The filter is
now operating in the normal filter mode, filtering dirt
particles from the pool water.
6. Adjust the pool suction and return valves to achieve
the desired flow. Check the system and filter for water
leaks and tighten connections, bolts and nuts, as
required.
d. Connect the pump to the control valve opening
marked PUMP. After connections are made,
tighten the valve flange clamps with the
screwdriver, tapping around the clamp with the
screwdriver handle to help seat the valve flange
clamp.
2. Make the connection from the pool pipe to the control
valve opening marked RETURN, and complete the
other necessary plumbing connections such as the
suction lines to the pump, waste line, etc.
3. Make the electrical connections to the pump, per
pump instructions.
4. To prevent water leakage, make sure all pipe
connections are tight.
Valve Key Assembly
1. Place the valve key so that wedge opening is at TOP
port. See handle in Figure 4. The flat edge of the
cover screw lug should align with the flat edge of the
body screw lug.
2. Position the cover O-rings.
3. Secure the assembly to the body with the cover
screws. Tighten the cover screws evenly and
alternately. Do not over-tighten.
