SERVICING
Be sure that disconnect power to the Variable Speed Pump at the circuit breaker and disconnect the communication
cable before servicing the pump. Electrical shock can cause serious or fatal injury. Read all servicing instructions
before working on the pump.
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 open with extreme
caution.
Be sure not to scratch or mar the polished shaft seal faces; seal will leak if faces are damaged. The polished and
lapped faces of the seal could be damaged if not handled with care.

The pump requires little or no service other than reasonable care, however, a Shaft Seal may occasionally become
damaged and must be replaced.
