Removal of Output Inductors (1

st 

Gen GP4 Classic Compressor 
Only)

Physically remove output inductor from each circuit. 
Remove thermal cutout limit switch connections 1B3 

(circuit 1) or 1B4 (circuit 2); connect wires 431D to wire 
433A (circuit 1); or connect wires 424D to wire 425A (circuit 
2). Bypass or cap off coolant lines that pass through the 
inductor. Reconnect the power conductors together with 
recommended POLARIS insulated in-line splice connector 
(See 

Step 6

).
