Wiring Diagram
Refrigeration System
The EREF 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 and is critically charged. Access fittings are provided for ease of service. However, the connection
of refrigeration service hoses to the fittings will almost invariably result in a significant change in the system charge.
This change can adversely affect the performance of your refrigerator. Therefore, Follett recommends that if hoses are
ever connected to the refrigeration system for service, the refrigerant should be recovered, the system evacuated, and
recharged by weighing in the correct refrigerant charge.
Note: Do not charge the system by pressures.
