SAFETY INSTRUCTIONS
1. DANGER：Risk of suction entrapment. Always turn off all power to the pool pump before installing the cover or
working on any suction outlet. This pump produces high levels of suction and creates a strong vacuum at the
main drain at the bottom of your pool or spa. This suction is so strong that it can trap adults or children under
water if they come in close proximity to a pool or spa drain or a loose or broken drain cover or grate. Stay off the
main drain and away from all suction outlets!
2. DANGER：Risk of suction entrapment. The use of unapproved covers or allowing use of the pool or spa when
covers are missing, cracked or broken can result in body or limb entrapment, hair entanglement, body
entrapment, evisceration and/or death. Limb Entrapment: When a limb is sucked or inserted into an opening
resulting in a mechanical bind or swelling. This hazard is present when a drain cover is missing, broken, loose,
cracked or not properly secured. Hair Entanglement: When the hair tangles or knots in the drain cover, trapping
the swimmer underwater. This hazard is present when the flow rating of the cover is too small for the pump or
pumps. Body Entrapment: When a portion of the body is held against the drain cover trapping the swimmer
underwater. This hazard is present when the drain cover is missing or broken, or the cover flow rating is not high
enough for the pump or pumps. Evisceration/Disembowelment: When a person sits on an open pool (particularly
a child wading pool) or spa outlet and suction is applied directly to the intestines, causing severe intestinal
damage. This hazard is present when the drain cover is missing, loose, cracked, or not properly secured.
Mechanical Entrapment: When jewelry, swimsuit, hair decorations, finger, toe or knuckle is caught in an opening
of an outlet or drain cover. This hazard is present when the drain cover is missing, broken, loose, cracked, or not
properly secured.
NOTICE: All suction plumbing must be installed in accordance with the latest national and local codes for
swimming pools, spas and hot tubs, including NSPI standards and CPSC guidelines.
3. DANGER：Risk of electric shock. Can shock, burn or kill. Connect only to a branch circuit protected by a ground-
fault circuit-interrupter (GFCI). Contact a qualified electrician if you cannot verify that the circuit is protected by a
GFCI. This 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 flowing, indicating the possibility of an electric shock. Do not use
this pump. Disconnect the pump and have the problem corrected by a qualified service representative before
using.

For Professional Technical Support call 1-844-242-2475 3
4. DANGER：Risk of hazardous pressure. Stand clear of pump and filter during start-up. Pool and spa circulation
systems operate under high pressure. When any part of the circulating system (i.e. locking ring, pump, filter,
valves, etc.) is serviced, air can enter the system and become pressurized. Pressurized air can cause the pump
housing cover filter lid and valves to violently separate which can result in severe personal injury or death. Filter
tank lid and strainer cover must be properly secured to prevent violent separation. Stand clear of all circulation
system equipment when turning on or starting up pump. Before servicing pool and spa equipment, make note of
the filter pressure. Be sure that all controls are set to ensure the system cannot inadvertently start during service.
Turn off all power to the pump. Place filter manual air relief valve in the open position and wait for all pressure in
the system to be relieved. Before starting the system, fully open the manual air relief valve and place all system
valves in the “open” position to allow water to flow freely from the pool and spa back to the pool or spa. Stand
clear of all pool and spa equipment and start the pump. Do not close filter manual air relief valve until all pressure
has been discharged from the valve and a steady stream of water appears. Observe filter pressure gauge and be
sure it is not higher than the pre-service condition.
5. DANGER: ALWAYS disconnect the power to the pump before servicing.
6. WARNING: Risk of harm. A clearly labeled emergency shut-off switch for the pool pump and spa jet pump must
be in an easily accessible, obvious place near the pool or spa. Make sure bathers know where it is and how to
use it in case of emergency.
7. WARNING：Risk of harm. To reduce the risk of injury, do not permit children to use this product unless they are
closely supervised at all times.
8. WARNING：Risk of hazardous pressure. Pool and spa circulation systems operate under high pressure.
Incorrectly installed or tested equipment may fail, causing severe injury or property damage. Read and follow
instructions in owner’s manual when installing and operating equipment. Have a trained pool professional perform
all pressure tests. Do not connect system to a high pressure or city water system. Use equipment only in a pool
or spa installation. Trapped air in the system can cause explosion. BE SURE all air is out of the system before
operating or testing the equipment. See the hazardous pressure warning below. Do not use compressed air to
clean, test, or purge equipment for winter.
9. WARNING：All work must be performed by a qualified pool professional, and must conform to all national, state,
and local codes.
10. WARNING：Risk of harm. Pumps improperly sized or installed or used in applications other than for which the
pump was intended can result in severe personal injury or death. These risks may include but not be limited to
electric shock, fire, flooding, suction entrapment or severe injury or property damage caused by a structural
failure of the pump or other system component.
11. CAUTION：Install to provide drainage of compartment for electrical components.
12. CAUTION：These instructions contain information for a variety of pump models and therefore some instructions
may not apply to a specific model. All models are intended for use in swimming pool applications. The pump will
function correctly only if it is properly sized to the specific application and properly installed.
13. CAUTION：Electrical controls such as on/off switches, timers, and control systems, etc. should be properly
installed to allow the operation (start-up, shut-down, or servicing) of any pump or filter without requiring the user
to place any portion of his/her body over or near the pump strainer lid or filter lid. Such installation should allow
the user to stand clear of the filter and pump during system start-up, shut down or servicing of the system. Never
open the inside of the drive motor enclosure. There is a capacitor bank that holds a 230 VAC charge even when
there is no power to the unit. The pump is not submersible. The pump is designed for use with chlorinated pools
only. For use with other applications, contact customer service. The pump is capable of high flow rates; use

caution when installing and programming to limit the pump's performance potential with old or questionable
equipment. This appliance is not intended for use by persons (including children) of reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction
concerning the use of the appliance by a person responsible for their safety.
14. CAUTION: Follow all local electrical and safety codes, along with the National Electrical Code (NEC). In addition,
all Occupational Safety and Health Administration (OSHA) guidelines must be followed.
15. IMPORTANT：To minimize the risk of injury due to suction entrapment hazard: Pools and spas should utilize a
minimum of two drains per pump. A properly installed and secured ANSI/ASMEA112.19.8 approved anti-
entrapment suction cover must be used for each drain. Each suction cover must be installed at least three (3’)
feet apart, as measured from the nearest point to nearest point. Regularly inspect all covers for cracks, damage
and advanced weathering. If a cover becomes loose, cracked, damaged, or broken, or is missing, close the pool
or spa immediately, shut off the pump, post a notice and keep the pool or spa closed until an appropriate certified
cover is properly installed. Replace drain covers as necessary. Drain covers deteriorate over time due to
exposure to sunlight, pool chemicals and weather. Avoid getting hair, limbs or body in close proximity to any
suction cover, pool drain or outlet. Disable suction outlets or reconfigure into return inlets.
16. IMPORTANT：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 pump trap lids to 30 ft. lbs.
(4.1 kg-m) torque for testing. Water pressure for test must be less than 25 PSI (7.5 kg/cm2). Water temperature
for test must be less than 100° F (38 °C). Limit test to 24 hours. After a test, visually check the system to ensure
that it is ready for operation. Remove the trap lid and re-tighten it by hand only.
NOTICE: These testing parameters apply only to the models described herein. For other equipment, consult the
manufacturer.

NOTICE: When connecting pipe to pump with union half, use PTFE tape between pipe and union adapter. Union
collar to pump should be assembled dry and hand-tightened.
Thread sealant tape instructions:
Use only new or clean PVC pipe fittings.
Wrap male pipe threads with one to two layers of PTFE tape.
Cover entire threaded portion of pipe.
Do not overtighten or tighten past thread stop in pump port!
If leaks occur, remove pipe, clean off old tape, rewrap with one
to two additional layers of tape and remake the connection.
NOTICE: Support all piping connected to pump!
Piping
Use at least 1-1/2 in. (38 mm) pipe (Use 2 in. (51 mm) pipe if
possible). Increase size if a long run is needed.
To avoid strains on the pump, support both suction and discharge pipes independently. Place these supports near
the pump.
To avoid a strain left by a gap at the last connection, start all piping at the pump and run pipe away from the
pump.
To avoid air locking, slope suction pipe slightly upward toward the pump.
NOTICE: To prevent flooding when removing pump for service, all flooded suction systems must have gate valves in
suction and discharge pipes.
Pool Pump Suction Requirements
WARNING: 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. Follow the guidelines below for a pump
installation which minimizes risk to users of pools, spas, and hot tubs.
Entrapment Protection
The pump suction system must provide protection against the hazard of suction entrapment or hair
entrapment/entanglement.
Suction Outlet Covers
All suction outlet covers must be maintained. They must be replaced if cracked, broken, or missing.
See Testing and Certification for outlet cover certification requirements.
All suction outlets must have correctly installed, screw fastened covers in place.

For Professional Technical Support call 1-844-242-2475 7
Suction Outlets per Pump
Provide at least two hydraulically balanced main drains, with covers, as suction outlets 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. apart.
The system must be built so that it cannot operate with the pump drawing water from only one main drain. There
must be at least two main drains connected to the pump whenever it is running.
However, if two main drains run into a single suction line, the single suction line may be equipped with a valve
which will shut off both main drains from the pump.
More than one pump can be connected to a single suction line as long as the requirements listed above are met.
Water Velocity
The maximum water velocity through the suction fitting or cover for any suction outlet must be 1.5 ft. per second
unless the outlet complies with the latest ASME/ANSI Specification for Suction Fittings For Use in Swimming Pools,
Spas, Hot Tubs, and Whirlpool Bathtub Applications. In any case, do not exceed the suction fitting’s maximum
designed flow rate.
If 100% of the pump’s flow comes from the main drain system, the maximum water velocity in the pump suction
hydraulic system must be 6 ft. per second or less even if one main drain (suction outlet) is completely blocked. The
flow through the remaining main drain(s) must comply with the latest ASME/ANSI Specification for Suction Fittings For
Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications.
Testing and Certification
Suction outlet covers must have been tested by recognized testing laboratory and found to comply with the latest
ASME/ANSI Specifications for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub
Applications.
Fittings
Fittings restrict flow; for best efficiency use the fewest possible fittings (but at least two suction outlets). Avoid fittings
which could cause an air trap. Pool fittings must conform to International Association of Plumbing and Mechanical
Officials (IAPMO) standards. Use only non-entrapping suction fitting or double suction.
Electrical
WARNING: Risk of electric shock. Can shock, burn or kill. Ground pump before connecting to power supply.
Ground motor before connecting to electrical power supply. Failure to ground motor can cause severe or fatal
electrical shock hazard.
To avoid dangerous or fatal electrical shock, turn OFF power to motor before working on electrical connections.
Ground Fault Circuit Interrupter (GFCI) tripping indicates an electrical problem. If GFCI trips and will not re-set,
have a qualified electrician inspect and repair electrical system.
Exactly match supply voltage to name plate voltage. Incorrect voltage can cause fire or seriously damage motor
and voids warranty. If in doubt consult a licensed electrician.

8For Professional Technical Support call 1-844-242-2475
WARNING: Risk of explosion. Do not ground to a gas supply line.
Voltage
Voltage at motor must be not more than 10% above or below motor name plate rated voltage or motor may overheat,
causing overload tripping and reduced component life. If voltage is less than 90% or more than 10% of rated voltage
when motor is running at full load, consult power company.
Grounding/Bonding
Install, ground, bond and wire motor according to local or National Electrical Code requirements. Permanently ground
motor. Use ground terminal “G” provided under motor canopy or access plate; use size and type wire required by
code. Connect motor ground terminal to electrical service ground.
Connect a No. 8 AWG (8.4 sq.mm) solid copper bonding wire to the bonding lug provided on the motor housing and to
all metal parts of the swimming pool, spa, or hot tub and to all electrical equipment, metal piping or conduit within 5 ft.
(1.5 m) of the inside walls of swimming pool, spa, or hot tub.
To Wire a Two-Speed Motor
NOTICE: Be sure power is off.
Remove the motor end cover. (FIG.1)
Using muti-function crimping pliers to press o-type grounding terminal which connected 14 AWG. (FIG. 2)
Install 1/2” connector to rear end cover. Install ground wire to ground rod. using muti-function crimping pliers to

Wire the pump as shown in the diagram below. (FIG.5)
Re-install the motor end cover.

For Professional Technical Support call 1-844-242-2475 9
Pump must be permanently connected to circuit. Table I gives correct wire and circuit breaker sizes for the pump
alone. If other lights or appliances are also on the same circuit, be sure to add their amp loads to pump amp load
before figuring wire and circuit breaker sizes. (If unsure how to do this or if this is confusing, consult a licensed
electrician.) Use the load circuit breaker as the master on-off switch.
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, see GFCI manufacturer’s
instructions.
In case of power outage, check GFCI for tripping (which will prevent normal pump operation). Reset if necessary.
NOTICE: If you do not use conduit when wiring motor, be sure to seal wire opening on end of motor to prevent dirt, bugs, etc., from
entering.

Priming Pump
Release all pressure from filter,
pump, and piping system; see the
filter owner’s manual.
In a flooded suction system (water
source higher than pump), pump will
prime itself when suction and
discharge valves are opened.
If pump is not in a flooded suction system, unscrew and remove trap cover; fill trap and pump with water. Do not
lubricate the trap cover O-ring. The original equipment O-ring contains a permanent internal lubricant.
NOTICE: If you replace the O-ring with a non-internally lubricated O-ring, you may need to apply a silicone based
lubricant. Clean and inspect O-ring; reinstall on trap cover. Replace trap cover on trap; turn clockwise to tighten cover.
NOTICE: Tighten trap cover by hand only (no wrenches)! Pump should prime now. Priming time will depend on
vertical length of suction lift and horizontal length of suction piping.
If pump does not prime within three minutes, make sure that all valves are open, suction pipe end is under water,
pump is not trying to lift water more than 10 ft. (3 m), and that there are no leaks in suction pipe. If necessary, see
Troubleshooting.
Storage/Winterizing:
NOTICE: Allowing pump to freeze will damage pump and void warranty!
NOTICE: Do not use anti-freeze solutions (except propylene glycol) in your pool/spa system. Propylene glycol, or “RV
antifreeze”, is non-toxic and will not damage plastic system components; other anti-freeze formulas are highly toxic
and may damage plastic components in the system.
Drain all water from pump and piping when expecting freezing temperatures or when storing pump for a long time (see
Draining Pump).
Keep motor dry and covered during storage.
To avoid condensation/corrosion problems, do not cover pump with plastic.
For outdoor/unprotected installations:
1. Enclose entire system in a weather proof enclosure.
2. To avoid condensation/corrosion damage, allow ventilation; do not wrap
system in plastic.
3. Use a 40% propylene glycol/60% water solution to protect pump to -50°F (-
46°C).
Draining Pump
WARNING: Risk of electric shock. Can shock, burn or kill. Disconnect power before working on pump or motor.
1. Pump down water level below all inlets to the pool.
WARNING: Risk of electric shock. Can shock, burn or kill. To avoid dangerous or fatal electrical shock hazard, turn
OFF power to motor before draining pump.
2. Remove trap cover and use low pressure air to blow accumulated water from the piping system. Never use high
pressure air to purge system.
3. Cap inlet piping after draining to keep water out of the pipes.
4. To prevent pump from freezing, remove trap cover and drain the tank body through the two drain plugs provided.
Clean pump thoroughly; replace trap cover and drain plug.
