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
(refrigerant R134a, 11.4 oz (322g).
Note: Do not charge the system by pressures.
Ambients
Intended for indoor use where ambient temperature, measured at the condenser inlet, does not exceed 80 F
(27C) and ambient relative humidity does not exceed 60% RH. A heated door is recommended for higher humidity
ambients.
Clearances
The top of the refrigerator must have 10 inches (25.4 cm) of clear space above the refrigerator to ensure proper
ventilation of the refrigeration system.
The back of the refrigerator should have 1 inch (2.5 cm) of clearance to allow for power cord clearance on unit and
an additional 1 inch (2.5 cm) if the unit is to be plugged in directly behind the refrigerator.
