Page 6: Pump Operation
operation Main Circuit Breaker: Operating handle for the main breaker is located behind the outer door which is pad-lockable for lock out/tag out. Rotating the handle to the OFF position turns power off to the panel. Rotating the handle to the ON position provides power to the control panel. If servicing the panel hot (door open and main breaker in energized position) be sure to align the keyed slot on back of the operating handle with the key on the main breaker shaft before closing the door. - Page 7 Integrated Basin Heater Control Circuit Option The Marley ABHi basin heater package controls the ON and OFF operation of the basin heater device providing freeze protection in the cold-water col- lection basin of the fluid cooler. The stand-alone control package includes a main circuit breaker disconnect that feeds a contactor providing power for the heater element.
- Page 8 operation Solid-state Water Level Control and Alarm Circuit Option The number of probes depends on the number of optional circuits being furnished. Each water level event requires one card. The card includes an on- board relay with (1) form “C” dry contact. Contacts are wired to a user terminal strip for connection to remote devices such as makeup solenoids and alarms.
