Power from the defrost contactor energizes Defrost Heaters and 208V Evaporator Fan Relay Coil(7). Relay Contacts open <br /> the fan circuit and energizes the Drain Pan Heater. <br /> 2. If the Defrost Heater raises internal air temperature above 90a17,the Defrost Limit Thermostat(4)will open. <br /> 3. When Defrost Termination Thermostat ends defrost period,the defrost contactor opens the Defrost Heater and Evaporator <br /> Fan Relay Coil Circuits. The Drain Pan Heater goes off and fans are on. <br /> 4. Standard low temperature Reach In cases with Innovator I doors are shipped with the DASH controller for door anti-sweat <br /> heater control installed. Do not connect the DASH controller input to a centralized anti-sweat system. It must be connected <br /> to a continuous 120V circuit for proper operation. <br /> 5. If the case is connected to a centralized anti-sweat controller that meets DOE compliance requirements,the DASH controller <br /> is not installed on the case. Feed the 120V controller output into terminal#12. <br /> 6. Options may be installed that have additional or replacement wiring diagrams. <br /> 7. Reach In cases with Innovator III doors do not have the DASH controller. <br /> 6 of 7 U.S.&CANADA 1-800-922-1919•MEXICO 1-800-890-2900 RLN with Innovator Doors or Innovator III Doors <br /> Technical Data Sheet <br /> Equip #2, 3 -Page 6 <br />
