Warning: Make certain that the system is disconnected from the power
source in compliance with all local and national codes before attempting
to service or remove any components. Never run the pump when dry.
Maintenance:
Inspection: Pump should be periodically checked for proper operation. If the system has changed
or if the pump is operating noisily or erratically, then the pump should be removed and examined.
It should be repaired and parts replaced as necessary.
Cleaning: Remove oil, dust, dirt, water, chemicals from exterior of pump and motor. Blow out
interior of open motors with clean compressed air at low pressure. Regularly drain moisture from
TEFC motors.

drained when not in operation or add sufficient antifreeze.
