IMPORTANT SAFETY INSTRUCTIONS
General Warnings
●Never open the inside of the drive motor enclosure.
●The pump is not submersible.
●Install this pump in a place with good drainage
●Before starting, all system valves must be in a position that allows water to return to the pool.
●Code requirements for the electrical connection differ from state to state. Install equipment
according to the National Electrical Code.
●Switch pump to OFF by disconnecting the main circuit to pump BEFORE servicing pump
WARNING- To reduce the risk of injuries, do not permit children to use this product unless
supervised.
WARNING- Risk of electrical Shock. Connect only to a circuit branch protected by
aground-fault circuit interrupter (GFCI). If you cannot verify if the circuit is protected by a GFCI, contact
a qualified technician. Pump must be permanently connected to a GFCI.

WARNING- This unit must only be connected to a supply circuit that is protected by a
ground-fault-circuit protection (GFCI). The GFCI should be provided by the installer and should be
tested on a routine basis. To test the GFCI, simply push the test button. The GFCI should interrupt
power. Push the reset button and the power should be restored. The GFCI is defective if it fails to
operate in this manner. If the GFCI interrupts the power to the pump without the test button being
pushed, this indicates a ground current is flowing and has the possibility of causing an electric shock.
Do not use the pump. Disconnect the pump and correct the issue with a qualified service technician
before using.
WARNING- To reduce the risk of electric shock, immediately replace damaged cords.
WARNING- This pump is only for use with permanently-installed pools and may 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 building, such that it is capable of being readily disassembled for
storage and reassembled to its original integrity.
WARNING- Hazardous Pressure- During startup, normal operation, and after pump shuts
off, the pool and spa water circulation system operates under hazardous pressure. Please stand clear
of the circulation system during pump start-up. Before servicing your pool equipment, make sure all
systems and pump controls are in the off position and the filter manual air relief valve is open. Also
make sure all system valves are set in a position that allows water to return to the pool. Do not change
the filter valve position while the system pump is running. All suction and discharge valves must be
open when starting the circulation system. Failure to follow safety and operational instructions could
result in damage, severe personal injury, or death.
WARNING- Separation Hazard- Please ensure the strainer cover is properly secured to
the pump housing. Do not operate pool and spa circulation systems if a system component is not
assembled properly, damaged, or missing. All suction and discharge valves must be open when starting
the circulation system. Failure to follow safety and operational instructions could result in damage,
severe personal injury, or death.

General Features
●Variable speed pumps provide maximum energy savings
●Simple interface that is easy to operate and program
●Real-time clock with 24-hour memory
●Removable strainer basket with a built-in thermal overload protection
●Totally-enclosed fan cooled (TEFC) motor
Location
Place the pump as close to the pool as it allows and run suction lines as direct as possible to reduce
friction loss. All suction lines should have a continuous slope upward from the lowest point in line.
Joints must be tight (but not over-tightened). Suction line diameter must equal or be larger than the
discharge line diameter. The suggested installation of the pump is 12” above the pool water level. The
pump should not be installed more than 30” above the pool water level.
Though the pump is designed for outdoor use, we strongly advise you to protect the electrical
components from the weather. Select a well-drained area that does not flood. Do NOT install pump in
a damp or non-ventilated area. Pump motors require free circulation and air for cooling.
Pump Mounting
Install the pump on a firm, level base or pad to meet all local and national codes. Fasten pump to base
or pad with screws or bolts to reduce vibration and stress on the pope or hose joints. The base MUST
be solid, level, rigid, and vibration free.

Pump Plumbing
There are many different ways a pool pump can be plumbed due to space requirements, existing
plumbing, water features, etc... Due to these scenarios, we have listed some general best practices to
adhere to when plumbing a pool pump.
Pool Plumbing Best Practices
●It is best to use larger plumbing on the suction side of the pump, as this will allow the pump to prime
easier and put less stress on the pump resulting in longer pump life.
○ For example, use 2” plumbing on the suction side of the pump and then use a 2” x 1.5” reducer
bushing to reduce down to the 1.5” pump suction port. If you can only install larger plumbing on
the 12” of pipe going into the pump, then this is fine, as you will still see benefits.
●Use a minimum of 12” of straight pipe going into the suction port of the pump.
●Avoid the use of 90-degree elbows within 12” of the suction port or discharge port of the pump. The
fewer 90-degree elbows, the better.
●The use of two 45-degree fittings is better than one 90-degree elbow.
●If you are having problems with your pump keeping prime after the pump shuts off, then the use of a
check valve on the suction side of the pump will help with keeping the pump primed. Make sure the
check valve is not too close to the suction port of the pump. See check valve placement
recommendations listed below.
Check Valve Placement
1.5” Plumbing - Check valve not to be placed within 7.5” of pump suction port
2” Plumbing - Check valve not to be placed within 10” of pump suction port
2.5” Plumbing - Check valve not to be placed within 12.5” pump of suction port

Check Valve Placement
• 1.5’’ plumbing, more than 7.5’’
from pump suction port
• 2’’ plumbing, more than 10’’
from pump suction port
• 2.5’’ plumbing, more than 12.5’’
from pump suction port
Suggested installation of pump is 12’’ above
water level.
The pump should not be installed more than
30’’ above water level.

Piping
1. Larger piping sizes improve pool plumbing.
2. Piping on the suction side of the pump should be the same or larger than the return port.
3. Plumbing on the suction side of the pump should be as short as possible.
4. For most installations, its is recommended you install a valve on both the pump suction and
return lines. This allows you to isolate the pump during routine maintenance. However, the valve,
elbow, or tee installed in the suction line should be no closer to the front of the pump than 5 times
the suction line diameter.
Example: A 2.5” pipe requires a 12.5” straight run in front of the suction inlet of the pump. This will help
the pump prime faster and last longer.
Note: Do NOT install 90-degree elbows directly into the pump inlet or outlet.
Fittings and Valves
1. Do not install 90-degree elbows directly into the pump outlet.
2. Flooded suction systems should have gate valves installed or suction and discharge pipes for
maintenance. However, the suction gate valve should be no closer than 5 times the suction pipe
diameter.
3. Use a check valve in the discharge line when using this pump for any application where there is
significant height to the plumbing after the pump.
4. Be sure to install check valves when plumbing in parallel with another pump. This helps prevent
reverse rotation of the impeller and motor.

Electrical Requirements
1. Install all equipment in accordance with the National Electrical Code and all applicable local
codes and ordinances.
2. A means for disconnection must be incorporated in the fixed wiring in accordance with the wiring
rules.
Voltage
The voltage at the motor must NOT be more than 10% above or below motor nameplate rated voltage
or the motor may overheat, causing the overload tripping.
Grounding and Bonding
Install, ground, bond, and wire motor in accordance with local or national electrical code. Make sure to
permanently ground the motor. Use green ground terminal provided under motor canopy or access
plate. Use the appropriate size and wire type required by code. Connect motor ground terminal to
electrical service ground.
Reference NEC codes for all wiring standards including, grounding, bonding, and general wiring
procedures.
Wiring
If the pump comes with a cord and plug, no wiring is needed. In some areas, power cords are
not provided to local electrical standards. Wire pump according to local electrician codes. Follow
the instructions below for wiring.
WARNING- All electrical wiring must be performed by a licensed electrician.
WARNING- All electrical wiring must conform to local codes and NEC regulations.
WARNING- Use copper conductors only.

Screw 1: Ground wire
Screws 2 & 3: Either of two live wires
Screws 4 & 5: Not used
CAUTION- NEVER run the pump dry. Running pump dry may damage seals, causing
leakage, flooding, and voids warranty. Fill strainer housing with water before starting the motor.
1. Remove the AC power connection terminal box cover. There are a total of 5 screws inside the
terminal box.
2. Ensure that the available electrical supply is suitable for the motor’s voltage, phase, cycle, and
that the wire size is adequate for the HP rating and distance from the power source.
3. The voltage from the power source must be within 90%-110% of the motor’s rated voltage.
Failure to keep within this range can result in overload tripping and reduced longevity.
4. Install, ground, bond, and wire the motor in accordance with local NEC requirements.
5. Ground the pump by connecting a grounding wire from the electrical service ground terminal to
the motor grounding screw.
6. Bond the motor to the pool structure. In short, this means creating an electrical connection
between the pump and swimming pool. This helps prevent potential hazards if you run into
electrical issues with the pump.
Start-Up and Operation
Prior to Start-Up
If it is necessary to perform a pressure test prior to initial use to ensure pump is functioning properly,
then the following criteria should be considered:
1. Hire a professional for the test.
2. Ensure all pump components are sealed properly to prevent leaks.
3. Remove any trapped air in the system by fully opening the filter air relief valve until a steady
stream of water is discharged.
4. Allow no more than 40 PSI at water temperature no higher than 100 F.
5. Do not run a pressure test for longer than 24 hours. Inspect all parts immediately to verify they
are intact and functioning properly.
6. Fill strainer housing with water to suction pipe level. Never operate the pump without water.
Wate acts as a coolant and lubricant for the mechanical shaft seal.
Do NOT add chemicals to the pool/spa system directly in front of pump suction. Adding undiluted
chemicals may damage pump and voids the warranty.

Priming Pump
All suction and discharge valves must be open as well as filter air relief valve when starting the circulat-
ing pump system. Failure to do so could result in severe personal injury.
Priming Pump Placed Below Water Level
● The pump will prime itself if it is placed lower than the water level.
Priming Pump Placed Above Water Level - If water level is lower than the pump, then following
these instructions for priming. The suggested installation of the pump is 12” above the pool water
level. The pump should not be installed more than 30” above the pool water level.
● Turn Power off to pool pump
● Make sure pool water is halfway up pool skimmer face
● Open suction valves
● Open discharge valves
● Open filters air release valve
● Unscrew and remove pump lid
● Remove any debris from pump basket
● Clean pool filter if needed
● Clean pool skimmer basket if needed
● Fill pump strainer basket with water from garden hose
● Clean and lubricate strainer cover O-ring each time it is removed. Inspect O-ring and place it
back on the strainer cover.
● Turn the strainer cover clockwise to tighten. NOTE: Tighten the strainer cover by hand only.
NO wrenches.
● Turn on the power to the pump and wait for the pump to prime. This may take up to five (5)
minutes. Priming time depends on the vertical length of the suction lift and the horizontal length
of the suction pipe. If the pump does not prime within five minutes, stop the motor and
determine the cause. Be sure all suction and discharge valves are open when the pump is
running.
● Once the water starts coming out of the pool filter air release close pool filter air release

Maintenance
● Clean strainer basket regularly. Do NOT strike the basket to clean. Inspect strainer cover gasket
regularly and replace as necessary.
● Pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary.
● Keep the motor clean. Ensure air vents are free from obstruction to avoid damage. Do NOT use
water to hose off the motor.
● Occasionally, shaft seals must be replaced. Replace with a genuine seal assembly kit.
Storage and Winterization
Do not purge the system with compressed air. Doing this can cause inside components to explode,
causing injury or death. Only use a low pressure (below 5 PSI), high volume blower when air purging
the pump.
