Pump Overview

This manual contains essential information about the installation, operation, and safe use of this pool pump. Failure to install according to the defined instructions will void your warranty.

Pump Installation

• Before servicing, all water circulation systems and pump controls must be in the off position, release all the pressure from the system.
• This pump should be serviced and installed by licensed professionals.
• Keep pump away from children.
• 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.

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

Ideal Installation

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, 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

• 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.

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.

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.

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.
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 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

ATTENTION- Wait five seconds before re-starting the pump. Failure to do so may cause reverse rotation of the motor and seriously damage the pump.

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.

WARNING- Allowing the pump to freeze will void your warranty

WARNING- Only use propylene glycol as antifreeze in your pool/spa. Propylene glycol is nontoxic and will not damage plastic system components. Other antifreeze combinations may damage plastic components in the system. Drain all water from the pump and piping whenever you are expecting freezing temperatures or when storing the pump for a long period of time.
Keep motor dry and covered during storage. To avoid condensation/corrosion issues, do NOT cover or wrap the pump with plastic film or bags.

1. Drain water level below all inlets to the pool.
2. Remove drain plus from bottom of strainer body and remove the strainer cover from the housing.
3. Disconnect pump from mounting pad, wiring system (AFTER power has been turned OFF), and piping systems.
4. Once the water is removed from the pump, re-install the strainer cover and drain plugs. Store pump in a dry area.
