— All control box internal wiring is supplied

from the factory in a harness assembly. Connect the coil of

HGBPR-A in series between TB5-3 and TB5-7. (Connect

the wires marked HGBPR-A-C1, HGBPR-A-C2 to the appro-

priate terminals.) See Fig. 7 (top section). Wire the coil of

HGBPR-B in series between TB5-4 and HGBPR-A-C2. (Con-

nect the wires marked HGBPR-B-C1 and HGBPR-B-C2 to the

appropriate terminals.) See Fig. 7 (top section).

For hot gas bypass on circuit A, locate a black wire in the

control harness with the label HGBPR-A-1, which originates at

TRAN 1. Connect the wires to the HGBPR-A-B, HGBPR-B-1,

HGBPR-B-2, TDR-HGA-1, TDR-HGA-4, and TB5-5 to the

correct terminals. See Fig. 7 (bottom section). For hot gas

bypass on circuit B, connect the wires labeled HGBPR-A-1,

HGBPR-A-4, HGBPR-A-5, HGBPR-B-4, HGBPR-B-6,

TDR-HGB-1, TDR-HGB-4, and TB5-6 to their correct termi-

nals. See Fig. 7 (bottom section). Connect the 620,000-ohm,

-w, field-supplied resistor across terminals 2 and 3 of the

time-delay relay. Repeat this procedure for the other time-delay

relay.

Wire in the solenoid valves. Terminal blocks are provided

for easy field wiring. Wiring external to the control box must

be run in field-supplied conduit. Use one of the

-in. (22-mm)

holes in the control box with a strain relief to run the wires to

the solenoid A (HGBPS-A) between TB5-5 and TB5-8. Con-

nect hot gas bypass solenoid B between TB5-6 and TB5-8. See

Fig. 7. Check all electrical connections for proper location and

tightness. Close and secure control box door.
