Defrost vapor enters evaporator causing a rise in temperature.At about 35°F the Control Relay Thermostat(5) <br /> closes the Fan Relay Coil(7)and Control Relay Coil(6)circuit. The Coil opens the Fan,Door Heater, <br /> and Frame Heater circuits,while energizing the Drain Pan Heater(9). <br /> 2. If the Drain Pan Heater(9)raises internal air temperature above 90°F,the Heater Limit Thermostat(4)will open. <br /> 3. When the defrost timer ends a defrost period,the evaporator temperature will start to fall. At about 20eF,the Control <br /> Relay Thermostat will open,de-energizing the Control Relay Coil and Fan Relay Coil(7).Control and Fan Relay's <br /> will open the Drain Pan Heater circuits,and will close the Fan,Door Heater,and Frame Heater circuits. <br /> Wiring Diagram is per side—two circuits required per case. <br /> P/N 0435492_J HUSSMANN CORPORATION•BRIDGETON,MO 63044-2483 U.S.A.•WWW.HUSSMANN.COM 7 of 8 <br /> Equip #1, 4, 5 -Page 7 <br />
