Electrical Connections - Evaporator(s)

Installation

Route the Evaporator Harness from the V-520 condenser into the cargo
box and make the following connections:

Host Evaporator

1. Defrost Termination Switch (12, CHB) to mating connector.

2. Hot Gas Defrost Solenoid (26, CHM) to mating connector.

3. Liquid Solenoid (B3-01,CHZ) to mating connector.

4. Temperature Sensor (PNK, BLK) to mating connector.

5. Drain Heaters (27, CHF) and (27A, CHG) to each mating connector.

See “Installation - Evaporator Drain Hoses” on page 52 regarding the
drain hoses and the correct placement of the drain pan heater wires.

6. Fan Motor 1 (EFI, CHC) to the mating connector.

7. Fan Motor 2 (EF2, CHD) to the mating connector.

OPTION - Door Switch (DSW1, CHH) to door switch connector.

NOTE: Make sure all harness are neatly routed and secured to prevent
rubbing or chafing against sharp edges inside the evaporator assembly.

Remote Evaporator

8. Defrost Termination Switch (12A, CHB2) to mating connector.

9. Hot Gas Defrost Solenoid (28, CHS) to mating connector.

10. Liquid Solenoid (33, CHY) to mating connector.

11. Temperature Sensor (G, B) to mating connector.

12. Drain Heaters (27B, CHF2) and (27C, CHG2) to each mating

connector. See “Installation - Evaporator Drain Hoses” on page 52
regarding the drain hoses and the correct placement of the drain pan
heater wires.

13. Fan Motor 3 (EF3, CHE) to the mating connector.

14. Fan Motor 4 (EF4, CHR) to the mating connector.

OPTION - Door Switch (DSW2, CHH2) to door switch connector.
