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 Coils (6).
These relays’ contacts open the Frame and Door Heater Circuits, and prevent the Fan Circuit from energizing upon defrost
termination.
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.
5. Temperature fall of the evaporator opens the Relay Control Thermostat (5) at about 20°F, de-energizing 120V A.S. Relay Coils (6).
A.S. Relay Contacts close the Frame and Door Heater Circuits, and Fan Circuit.

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 and Control Relay Coil (6) circuit. The Coil opens the Fan, Door Heater, and Frame Heater circuits,
while energizing the Drain Pan, Bottom, and Plenum Heaters
(9), (10) and (11).
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.
