Service

The temperature controller and evaporator probe indicate when the refrigeration system is required to turn on andoff.

The refrigeration system removes heat from the cabinet interior and rejects it to the surrounding room air. When the evaporator probe temperature reaches 5.0 C (9.0 F) above the controller set point, the probe signals the controller to turn the refrigeration system on. The normally open controller contacts close and energize the condenser fan motor and compressor. The compressor uses a current-style starting relay and a starting capacitor to start the compressor motor.

When the evaporator temperature falls to 5.0 C (9.0 F) below the set point, the probe signals the controller to turn the refrigeration system off. The controller contacts reopen, which de-energizes the condenser fan motor and the compressor. The evaporator fan motor runs continuously.

Any accumulated frost on the evaporator coils melts during the off cycle. The condensate drains to a drain pan mounted in the base of the refrigeration unit. The pan is located under the compressor. The heat from the compressor, condenser and fan evaporates any condensate in the drain pan as well as providing preliminary cooling of the high pressure vapor prior to entering the condenser.

Refrigeration system

The REF20/25 series refrigeration system is designed to give many years of trouble-free service. Except for routine cleaning of the air-cooled condenser and related parts, the refrigeration system requires no service or maintenance. The system uses a capillary tube metering device and is critically charged. Access  ttings 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.

Note: Do not charge the system by pressures.

Controller operation

ATTENTION

BEFORE MAKING ANY CHANGES TO FACTORY-DEFAULT REFRIGERATION SETTINGS, CONTACT FACTORY.

The controller displays product temperatures in degrees C or F (C is factory default) to 1 decimal point.

The controller is pre-programmed with a 0.5 C (32.9 F) set point which provides a compressor cut-in at 5.5 C (41.9 F) evaporator coil temperature and cut-out at -4.5 C (23.9 F) evaporator coil temperature. This will correlate to a product temperature of approximately 4.0 C (39.2 F).

All set points have a 5 C (9.0 F) differential. The 5.0 C (9.0 F) differential means that with a 0.5 C (32.9 F) set point, for example, the compressor will turn off at -4.5 C (23.9 F) evaporator temperature and turn on when the evaporator temperature reaches 5.5C (41.9 F).

Product temperature will be displayed on the digital temperature display and chart recorder (if equipped).
