Always disconnect power to the pump at the circuit breaker and relieve pressure in the filtration system 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. Do NOT attempt to adjust or
service without consulting your dealer or a qualified pool technician. Read the entire Installation and Maintenance Guide before attempting to use, service, or
adjust the pool filtering system or heater.
Do NOT open the pump 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, ensure the suction and return valves are open and strainer pot temperature is cool
to touch, then open with extreme caution.
To prevent damage to the pump and for proper operation of the system, clean pump strainer and skimmer baskets regularly.

Cleaning the Pump Strainer Basket

The strainer pot is located at the front of the pump and
houses the pump strainer basket.
The strainer basket can be viewed through the strainer
pot lid and should be visually inspected at least once
a week. Regularly emptying and cleaning the strainer
basket will lead to higher filter and heater efficiency and
prevent unnecessary stress on the pump motor.
TO CLEAN THE STRAINER BASKET:
1. Press ON/STOP to stop the pump and disconnect
all power to the pump at the circuit breaker.
2. Open the filter's air relief valve and relieve all
pressure from the filtration system.
3. Turn the strainer pot lid counter-clockwise and
remove it from the pump.
4. Remove the strainer basket and rinse out all debris.
Replace the basket if it is cracked or damaged.
5. Place the strainer basket back into the strainer pot.
Ensure the opening in the front of the strainer basket
is aligned with the suction outlet.
6. Fill the strainer pot up to the suction port with water.
7. Clean the lid O-ring and sealing surface of the
strainer pot.
Note: It is important to keep the lid O-ring clean.
8. Reinstall the lid by placing it onto the strainer pot
and tightening clockwise until the lid handles are
perpendicular to the suction port.
Note: Ensure the lid O-ring is properly placed and
is not being pinched between the lid and strainer
pot.
9. Open the filter air relief valve and stand clear of the
filter.
10. Reestablish power to the pump at the circuit breaker
and start the pump.
11. When a steady stream of water flows from the filter
air relief valve, close the valve.
THIS SYSTEM OPERATES UNDER HIGH PRESSURE. When
any part of the circulating system is serviced, air can enter the
system and become pressurized. Pressurized air can cause the
lid to separate which can result in serious injury, death, or property
damage. To avoid this potential hazard, follow above instructions.

MAINTENANCE

Winterizing

Do NOT rely solely on Thermal Mode to protect
your filtration system from freezing temperatures.
Thermal Mode is based on the internal drive temperature and may not
reflect actual air temperature.
You are responsible for determining when freezing
conditions may occur. If freezing conditions are
expected, take the following steps to reduce the risk of
freeze damage. Freeze damage is not covered under
warranty.
In mild climate areas, when temporary freezing
conditions may occur, run your filtering equipment all
night to prevent freezing.
TO PREVENT FREEZE DAMAGE:
1. Press ON/STOP to stop the pump and disconnect
all power to the pump at the circuit breaker.
2. Open the filter's air relief valve and relieve all
pressure from the filtration system.
3. Remove both drain plugs from the bottom of the
strainer pot and drain the pump. Store the plugs in
the strainer basket.
4. Cover the motor to protect it from severe rain, snow
and ice.
Note: Do not wrap motor with plastic or other air
tight materials during winter storage. Never cover
the motor when operating or expecting operation.
