4.Remove and save two screws holding J-Box. (See Fig. 24.)

5.Pull furnace power wires out of 1/2-inch (12 mm) diamet- er hole in J-Box. Do not loosen wires from strain-relief wire-tie on outside of J-Box.

6.Route furnace power wires through holes in casing and electrical box and into electrical box.

7.Pull field power wires into electrical box.

8.Remove cover from furnace J-Box.

9.Route field ground wire through holes in electrical box and casing, and into furnace J-Box.

10.Reattach furnace J-Box to furnace casing with screws re- moved in Step 4.

11.Secure field ground wire to J-Box green ground screw.

12.Complete electrical box wiring and installation. Connect line voltage leads as shown in Fig. 23. Use best practices (NEC in U.S. for wire bushings, strain relief, etc.

13.Reinstall cover to J-Box. Do not pinch wires between cover and bracket.

POWER CORD INSTALLATION IN FURNACE J-BOX

NOTE: Power cords must be able to handle the electrical requirements listed in Table 7. Refer to power cord manufacturer’s listings.

1. Remove cover from J-Box.

2.Route listed power cord through 7/8-inch (22 mm) dia- meter hole in J-Box.

3.Secure power cord to J-Box bracket with a strain relief bushing or a connector approved for the type of cord used.

4.Secure field ground wire to green ground screw on J-Box bracket.

5.Connect line voltage leads as shown in Fig. 23.

6.Reinstall cover to J-Box. Do not pinch wires between cover and bracket.

BX. CABLE INSTALLATION IN FURNACE J-BOX

1.Remove cover from J-Box.

2.Route BX cable into 7/8-inch (22 mm) diameter hole in J-Box.

3.Secure BX cable to J-Box bracket with connectors ap- proved for the type of cable used.

4.Secure field ground wire to green ground screw on J-Box bracket.

5.Connect line voltage leads as shown in Fig. 23.

6.Reinstall cover to J-Box. Do not pinch wires between cover and bracket.

24-V WIRING

Make field 24-v connections at the 24-v terminal strip. (See Fig. 33.) Connect terminal Y/Y2 as shown in Fig. 26-32 for proper cooling operation. Use only AWG No. 18, color-coded, copper thermostat wire.

The 24-v circuit contains an automotive-type, 3-amp. fuse located on the control. Any direct shorts during installation, service, or maintenance could cause this fuse to blow. If fuse replacement is required, use ONLY a 3-amp. fuse of identical size.
