TYPICAL WIRING DIAGRAM NOTES (SEE FIGURES 14 THRU 17)

1.All field wiring to be accomplished following city, local and/or national codes in effect at time of installation of this unit.

2.Caution: Label all wires prior to disconnection when ser- vicing controls. Wiring errors can cause improper and dangerous operation. If any of the wire as supplied with this unit must be removed it must be replaced with type 105°C, 600V wire or equivalent clearly renumbered for identification. Verify proper operation after servicing.

3.Motors inherently protected.

4.Factory wired for 460V operation.

5.See unit nameplate for maximum fuse size and/or circuit breaker size and minimum circuit ampacity.

6.If both LR and ASCT are present, wire 801/BL and 805/ BL are connected to ASCT-3. If only LR is present wire 801/BL and 805/BL are connected to M1 coil. If only

291627-YTG-B-0807

ASCT is present wire 202/Y is connected to ASCT-3. If neither LR or ASCT are present, wire 202/Y is connected to M1 coil as shown.

7.Shunt contact also used with crankcase heater. (optional)

8.Unit factory wired for low or medium speed indoor blower operation. To change motor speed, connect speed tap wires from indoor blower motor, per Detail A (Figure 19). Tape unused speed tap wires to prevent shorting and secure.

9.Select indoor blower speed to remain within the temper- ature rise range on the nameplate in heating.

Open all disconnects before servicing this unit.
