PUMP OPERATION

WARNING
Pump Damage.
Do not start the pump until it has been filled with
water and the system has been purged of air.

7. Starting the pump

• Do not start the pump until it has been filled with water
and the system has been purged of air.
• Open the service valves on both sides of the pump to fill
the system with water. Check for leaks.
• Turn the air vent screw in the middle of the housing
counterclockwise until you hear air escape from the
system. Placing a rag under the vent holes will help collect
water.

pump has been running, the pump can become very
hot.
