Maintenance
Always disconnect the electrical supply
before attempting to install, service, relocate or perform any maintenance. If the power source is out of sight, lock and tag in the open (off) position to prevent unexpected power application. Failure to do so could result in fatal electrical shock. Only qualified electricians should repair this unit. Improper repair could result in fatal electrical shock.
1 . Let the pump cool for a minimum of two hours before servicing because the pump contains hot oil under pressure and the motor is hot.
2 . Disassembly of the motor prior to expiration of warranty will void the warranty. If repairs are required, see troubleshooting chart.
3 . Inlet should be kept clean and free of all foreign objects and inspect annually. A clogged inlet will damage pump.
4 . Pump should be checked monthly for proper operation. Pump can be checked for proper operation by briefly removing pump power cord from the back of the water sensor plug and inserting directly into the
grounded outlet. In this condition, the pump will run continuously. Once pump operation is verified, replace pump power cord into the back of the water sensor plug (see Figure 2).
5 . Wipe water sensor surface regularly to prevent silt or other coatings from building up on sensor face (see Figure 2).
This pump contains dielectric oil for
cooling. This oil can be harmful to the environment. Check the state environmental laws before disposing this oil.
