Electric Defrost Sequence - Low Temperature

1. Power from the defrost contactor energizes Defrost Heaters and 208V Evaporator Fan Relay Coil (7). Relay Contacts open the

fan circuit and energizes the Drain Pan Heater.

2. If the Defrost Heater raises internal air temperature above 90°F, the Defrost Limit Thermostat (4) will open.

3. Temperature rise of the evaporator closes the Relay Control Thermostat (5) at about 35°F, energizing 120V A.S. Relay Coil (6).

This relay’s contacts open the Frame and Door Heater Circuits.

4. When Defrost Termination Thermostat ends defrost period, the defrost contactor opens the Defrost Heater and Evaporator Fan

Relay Coil Circuits. The Drain Pan Heater goes off and fans are on.

5. Temperature fall of the evaporator opens the Relay Control Thermostat (5) at about 20°F, de-energizing 120V A.S. Relay Coil (6).

A.S. Relay Contacts close the Frame and Door Heater Circuits.

Gas Defrost Sequence - Low Temperature

1. Defrost vapor enters evaporator causing a rise in temperature. At about 35°F the Control Relay Thermostat (5)

closes the Fan Relay Coil (7) and Control Relay Coil (6) circuit. The Coil opens the Fan, Door Heater,

and Frame Heater circuits, while energizing the Drain Pan Heater (9).

2. If the Drain Pan Heater (9) raises internal air temperature above 90°F, the Heater Limit Thermostat (4) will open.

3. When the defrost timer ends a defrost period, the evaporator temperature will start to fall. At about 20°F, the Control

Relay Thermostat will open, de-energizing the Control Relay Coil and Fan Relay Coil (7). Control and Fan Relay’s

will open the Drain Pan Heater circuits, and will close the Fan, Door Heater, and Frame Heater circuits.
