IMPORTANT SAFETY INSTRUCTIONS
General Warnings
● Never open the inside of the drive motor enclosure.
● The pump is not submersible.
● 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- Do not permit children to use this product.
WARNING- Risk of electrical Shock. Only connect to a circuit branch protected by a ground-fault
circuit interrupter (GFCI). Contact a qualified technician if you cannot verify if the circuit is protected by a
GFCI. Pump must be permanently connected to a GFCI.
WARNING- The pump is intended for use on permanently installed swimming pools and may
also be used with hot tubs and spas if so marked. Failure to bond pump to a pool structure increases the risk
for electrocution and could result in injury or death. To reduce the risk of electric shock, the electrician must
comply with installation instructions and must bond pump accordingly. Electrician must also conform to
electrical codes for bonding requirements.
WARNING- The pump can produce high levels of suction within the suction side of the plumbing
system. These high levels of suction can pose a risk if a person comes within close proximity of the suction
openings. A person can also be seriously injured by the high level of vacuum or may become trapped and
drown. It is critical that the suction plumbing is installed in accordance with the latest national and local codes
for swimming.

DANGER- Suction Entrapment Hazard. The pump produces high levels of suction, thus creating
a strong vacuum at the main drain at the bottom of your swimming pool/spa. This suction is so strong that it
can trap adults and children under water if they come in close proximity to the drain.
The use of unapproved drain covers, or allowing the use of your pool or spa when drain covers are either
missing or broken, can result in body or limb entrapment, hair entanglement, body entrapment, evisceration,
and/or death.
Hair Entrapment: When the hair tangles or knots in the drain cover, trapping the swimmer underwater. This
is typically associated with the flow rating when the flow rating of the cover is too small for the pump(s).
Limb Entrapment: A limb can be sucked or inserted into an opening in the drain, causing a mechanical bind
or swelling of the limbs. This is typically caused when the drain cover is missing, broken, cracked, or properly
secured.
Body Suction Entrapment: A portion of the body is held against the drain cover, trapping the swimmer
underwater. This typically presents itself when the drain cover is missing, broken, or the cover flow rating is
not high enough for the pump(s).
Evisceration/Disembowelment: Negative pressure that is applied directly to the intestines through an
unprotected suction outlet or suction outlet cover that is damaged, cracked, missing, or unsecured.
Mechanical Entrapment: Jewelry, clothes, hair decorations, fingers, toes, or knuckles can get caught in an
opening of a suction outlet cover.
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 circula-
tion 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
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 system 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.

Pump Dimensions
Pump Installation
Before servicing, all water circulation systems and pump controls must be in the off position, releasing all the
pressure from the system.
WARNING- This pump should be serviced and installed by licensed professionals.
Location
Place 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-ven-
tilated 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. 2” or 2.5” plumbing going into the suction port
of the pump is recommended.
○ Example 1 - Use 2.5” plumbing on the suction side of the pump and then use a 2” x 2.5” reducer bushing
to reduce down to the 2” 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.
○ Example 2 - Use 2” plumbing on the suction side of the pump. If you can only install larger plumbing on
the 12” 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 the suction port

Improper Installation
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, we recommend installing 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 mainte-
nance. 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
For Single Speed Pumps:
If the pump comes with a power cord, no wiring needed. If not, wire the pump as below:
How to wire 230v
1. Make sure switch is at the 230v side.
2. Ground wire connects to the ground terminal.
3. Hot wires connect to terminal 1 and 3, either hot wire is compatible to terminal 1 or 3. 4. Turn on the power
and run the pump.
How to wire 115v
1. Make sure switch is at the 115v side.
2. Ground wire connects to the ground terminal.
3. Hot wire connects to terminal 1 or 3, neutral wire connects to terminal 3 or 1. Either hot wire or neutral wire
is compatible to terminal 1 or 3.
4. Turn on the power and run the pump.
For Two Speed Pumps:
If pump comes with a power cord, no wiring needed. If not, wire the pump as below:

1. Ground wire connects to the ground terminal.
2. If your power supply has two hot wires, connect them to each terminal marked with “Line”; If your power
supply has one hot wire and one neutral wire, connect either of them to either of the terminal marked with
“Line”.
3. Turn on the power and run the pump.
Make sure that the electrical supply available is suitable for the motor’s voltage, phase, and cycle, and that
the wire size is adequate for the HP(KW) rating and distance from the power source.
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.

Voltage from the power must be in the range from 90% to 110% of the motor name plate rated voltage.
Otherwise, the motor may overheat and result in overload tripping and reduced component life.
Install, ground, bond, and wire motor in accordance with local or NEC requirements. Motor should be
grounded permanently by connecting ground terminal to electrical service ground.
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 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. Water acts as
a coolant and lubricant for the mechanical shaft seal.
CAUTION- NEVER run pump dry. Running pump dry may damage seals, causing leakage,
flooding, and voids warranty. Fill strainer housing with water before starting motor.
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.
ATTENTION- Before removing strainer cover:
1. STOP PUMP before proceeding.

2. CLOSE VALVES in suction and outlet pipes
3. RELEASE ALL PRESSURE from pump and piping system using filter manual air relief valve.
Priming Pump
All suction and discharge valves must be open as well as filter air relief valve when starting the circulating
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
