Winterizing

To protect the IntelliFlo 4 pump electronics from damage due to freezing conditions, the pump will switch it self on to generate internal heat when the air temperature drops below 40° F. This feature is not intended to protect the system plumbing from freezing.

1.If the air temperature drops below 40° F the water in the pump can freeze and cause damage. Freeze damage is not warrantable.

2.To prevent freeze damage follow the procedures listed below.

•Shut off electrical power for the pump at the circuit breaker.

•Drain the water out of the pump by removing the two thumb-twist drain plugs located at the bottom of the volute. Store the plugs in the pump basket.

•Cover the motor to protect it from severe rain, snow and ice.

•Do not wrap the motor in plastic. It will cause condensation and rust on the inside of the motor.

Note: In mild climate areas, when temporary freezing conditions may occur, run your filtering equipment all night to prevent freezing.

Priming the pump after service

Before a system start-up, the pump and system must be manually primed. Make sure to reopen valves before operating. To prime IntelliFlo 4, the strainer pot must be filled with water.

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. Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal.

For instructions about how to prime the IntelliFlo 4 pump, refer to “Priming the pump for the first time or after servicing,” on page 7.
