Operation

The MiniPac ECU is controlled by a thermostat that senses the internal cabinet temperature. When cooling is desired, the compressor, evaporator blower and condenser blower are energized. Cool air is discharged near the bottom of the MiniPac into the cabinet. When two MiniPacs are used on the same cabinet, the Marvair LL357A provides temperature control of the redundant units and equal run time on both units. A field installed jumper wire on the voltage control board in the MiniPac will permit the evaporator blower to run continuously. The MiniPac can also be immediately shut off when used in cabinets with a fire or smoke alarm system. Please refer to the Installation Manual for details.
