DocumentDocumentQuick Start Guide Universal Field-Mount Refrigeration Controller JULY 2023 PART NO. 25011701 intelliGenTM Field Mount (iFM) Kit for Unit Coolers The intelliGenTM Field Mount Kit is designed to install in the field for new unit coolers without factory mounted controls or retrofit of existing unit coolers with mechanical control to electronic control. The intelliGen control can be remote mounted away from the unit cooler at a convenient location for easy access. It is pre-assembled in a IP65 rated housing for both indoor and outdoor applications. Components Included The iFM kit comes with the intelliGen controller, 3 temperature sensors, 1 pressure transducer with wire harness, 1 terminal board and mounting accessories. The temperature sensors and pressure transducer harness are 25 feet in length. Other wire lengths are available as optional kit in separate part numbers. Components Not Included Individual system dependent components are not included in the kit but required for each installation. These components include the 24VAC control power transformer, the electronic expansion valve (EXV), the field wires for control power, fan motors, defrost heaters and solenoid valve. Field wire runs between the intelliGen controller and the unit cooler should be in conduits and have to meet local building and electric code requirements. Conduit fittings are needed for the conduit runs. Please conduct a site survey and review your local codes for detail requirements prior to installation.
