WIRING

WARNING: RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. This pool pump must be installed by a licensed or certified electrician or a qualified pool serviceman in accordance with the National Electrical Code and all applicable local codes and ordinances. Improper installation will create an electrical hazard which could result in death or damage to property. Always disconnect power to the pool pump at the circuit breaker before servicing the pump. Failure to do so could result in death or serious injury to serviceman, pool users or others due to electric shock.

1. Make sure all electrical breakers and switches are turned off before wiring motor.
2. Make sure that the wiring voltage matches the motor voltage (230v or 115v). If they do not match the motor will burn up.
3. Choose a wire size from Chart 1. When in doubt use a heavier gauge (larger diameter) wire. Heavier gauge will allow the motor to run cooler and more efficient.
4. Cut wires to the appropriate length so they don’t overlap or touch when connected to the terminal board.
5. Make sure all electrical connections are clean and tight.
6. Permanently ground the motor using the correct wire size and type specified by National Electrical Code. Make sure the ground wire is connected to an electrical service ground.
7. Bond the motor to the pool structure in accordance with the National Electrical Code. Use a solid No. 8 AWG or larger copper conductor. Run a wire from the brass external bonding clamp to the pool bonding structure.
8. Connect the pump permanently to a circuit. Make sure no other lights or appliances are on the same circuit.

POWER DEFENDER 2.25 HP & 2.7 HP VARIABLE SPEED MOTOR WARNINGS & ASSISTANCE

• Please store this instruction sheet and the motor user interface booklet in a safe place for future use.
• Please carefully read the entire enclosed booklet for the operation and troubleshooting of the Power Defender 225 and 270.

PUMP STRAINER BASKET

This unit, sometimes referred to as the “Hair and Lint Pot”, is the unit in front of the volute. The lint pot must be installed using only teflon tape on the threads. Do not use liquid chemical thread sealant. The basket inside the chamber must be kept clean of leaves and debris at all times. View basket through the “See Through Lid” to inspect for leaves and debris. Regardless of the length of time between filter cleaning, it is most important to visually inspect the hair and lint pot basket at least once a week. A dirty basket will reduce the efficiency of the filter and heater and also put an abnormal stress on the pump motor which would result in a costly repair bill.\

• WARNING: DO NOT open the strainer pot if pump fails to prime or if pump has been operating without water in the strainer pot. Pumps operated in these circumstances may experience a build up of vapor pressure and may contain scalding hot water. Opening the pump may cause serious personal injury. In order to avoid the possibility of personal injury, make sure the suction and discharge valves are open and strainer pot temperature is cool to touch, then with extreme caution.
• CAUTION: To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer baskets regularly.
• WARNING: THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATION SYSTEM (e.g. LOCK RING, PUMP, FILTER, VALVES, ETC) IS SERVICED, AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED. PRESSURIZED AIR CAN CAUSE THE LID TO BLOW OFF WHICH CAN RESULT IN SEVERE INJURY, DEATH, OR PROPERTY DAMAGE. TO AVOID THIS POTENTIAL HAZARD, FOLLOW THESE INSTRUCTIONS.

RESTARTING INSTRUCTIONS & PRIMING THE PUMP

CAUTION: DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking. If this occurs, the damaged seal must be replaced. ALWAYS maintain proper water level in your pool. If the water level falls below the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the pump to run dry, resulting in a damaged seal.

If the pump is installed below the water level of the pool, close return and suction lines prior to opening hair and lint pot on pump. Make sure to re-open valves prior to operating.
The pump strainer pot must be filled with water before the pump is initially started. Follow these steps to prime the pump. For 2-speed pumps: Pump should run on high-speed for priming.

1. Remove the pump lid.
2. Fill the pump strainer pot with water.
3. Reassemble the pump lid onto the strainer pot. The pump is now ready to prime.
4. Open the manual air relief valve on top of the filter, and stand clear of the filter.
5. Turn on the switch or time clock.
6. When water comes out of the manual air relief valve, close the valve. The system should now be free of air and circulating water to and from the pool.
   NOTE: Self-priming pump may take up to 3 1/2 minutes to reach a lift height of 10 feet.
