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.

1. Turn off motor.

2. Relieve pressure in the system.

3. Turn the lid in a counter-clockwise direction until it stops.

4. Lift lid and remove basket.

5. Put the debris from the basket into the trash and rinse out the basket. If the basket is cracked, it should be replaced.

6. Replace the basket and fill the pump pot and volute up to the inlet port with water.

7. Clean the cover, O-ring and sealing surface of the pump pot.
   Grease the O-ring with Teflon or silicone.

8. Reinstall the lid (Figure 2).

9. Make sure the lid O-ring is properly placed. Seat the lid then turn clockwise until hand tight (DO NOT over tighten with tools) (Figure 3).

10. Turn the power “ON” at the house circuit breaker. Reset the pool time clock to the correct time.

11. Open the manual air relief valve on top of the filter.

12. Stand clear of the filter. Start the pump.

13.  Bleed air from the filter until a steady stream of water comes out.
    Close the manual air relief valve.

WINTERIZING

If the air temperature drops below 35º F. the water in the pump can freeze and cause damage. Freeze damage is not warrantable.

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.

TROUBLESHOOTING
