Winterizing

The IntelliFlo's internal anti-freeze protection is disabled when connected to an IntelliTouch. Freeze
protection is provided by selecting YES at the ON WITH FREEZE portion of the IntelliTouch's
appropriate circuit function menu. To re-enable the IntelliFlo's internal anti-freeze protection, the power
to the drive must be cycled off then back on.
1. If the air temperature drops below 35° 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.

Manual Priming and Initial Start-up 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, the strainer pot must be filled with water.
CAUTION —
To prime the IntelliFlo pump:
1. Turn the pump clamp and lid in a counterclockwise direction until it stops and remove them.
2. Fill the pump strainer pot with water.
3. Reinstall the pump clamp and lid onto the strainer pot. The pump is now ready to prime.
IntelliFlo VF Installation and User's Guide
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.
