    The system uses a thermostatic expansion valve (TXV) metering device and is critically charged. Access fittings are not provided. Temporary piercing valves are required to work on the refrigeration system. Follett recommends that if hoses are ever connected to the refrigeration system for service, the refrigerant should be recovered, permanent access valves should be installed and the system evacuated, and recharged by weighing in the correct refrigerant charge (10.6 oz.

  • Page 24: Controller Operation

    After defrost terminates, there is a 2 minute drip time delay to allow excess condensation to drip off the evaporator coil before the compressor and condenser fan motor cycle on. The evaporator fan motor is off during defrost and is delayed an additional 4 minutes for a total delay of 6 minutes after defrost terminates before cycling on. The heat from the compressor, condenser and hot gas discharge line along with the airflow from the condenser fan evaporates any condensate in the drain pan as well as providing preliminary cooling of the high pressure vapor prior to entering the condenser.
