Limited Service Fire Pump Controller
I Introduction
The Hubbell Limited Service Fire Pump Controller provides automatic and manual control of small electric motor driven fire pumps and booster pumps of 30 horsepower or less.
All Controller components are inside the cabinet with indicating lights and switch handles located next to the door. A pressure switch initiates automatic starting of the pump motor. The Controller monitors the power phases and voltage. The CIRCUIT BREAKER DISCONNECTING MEANS handle has a door interlock feature to prevent opening the door when the switch is closed. The Controller also has an EMERGENCY MANUAL CONTROL handle to start the fire pump manually.

III Receiving, Handling, and Storage
1.Immediately upon receipt, carefully unpack and inspect the Controller for damage that may have occurred in shipment. If damage or rough handling is evident, file a damage claim with the transportation carrier.
2.If the Controller must be stored, cover it and place in a clean, dry location. Avoid unheated locations where condensation can result in damage to the insulation or corrosion of metal parts.
IV Installation
1.Consult the motor nameplate to determine voltage, current, and horsepower rating and compare with the Controller nameplate for matching data.
2.Release the door interlock by moving the CIRCUIT BREAKER DISCONNECTING MEANS to the OFF position.
3.Inspect the control transformer’s primary connections for agreement with the line voltage of the incoming power.
4.Exercise all switches and contactors, without power, to see that they operate freely.
5.Choose a location or base for the Controller that is non-combustible and within site of the motor. The base should not be subject to excessive vibration that may cause erratic operation of the PS (pressure switch). The Controller should be leveled so that the PS is level. Sight across the PS cover screws.
