SERVICING
Always disconnect power to the pump at the circuit breaker before servicing the pump. Failure to do so could result in death or serious
injury to service people, users or others due to electric shock. Read all servicing instructions before servicing 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.
