(5) Safety Interlocks
Motor thermostat protect the pump motor from overheating due to extended current draws in excess
of the motor rating. Under a persistent overload condition, motor thermostat opens a contact, which
interrupts the motor run circuit. A brief cool down interval permits restarting the pump.
WARNING
Check Safety Interlock functions periodically (every 6 months) to confirm the interlocks
will work correctly.
