WARNING!
WARNING! To avoid possible injury or death due to
electrical shock, open the power supply disconnect switch
and secure it in an open position during installation.
CAUTION!
CAUTION! Use only copper conductors for fi eld installed
electrical wiring. Unit terminals are not designed to accept
other types of conductors.

Electrical - Line Voltage

All fi eld installed wiring, including electrical ground, must
comply with the National Electrical Code as well as all
applicable local codes. Refer to the unit electrical data for
fuse sizes. Consult wiring diagram for fi eld connections that
must be made by the installing (or electrical) contractor.
All fi nal electrical connections must be made with a length of
fl exible conduit to minimize vibration and sound transmission
to the building.
General Line Voltage Wiring
Be sure the available power is the same voltage and phase
shown on the unit serial plate. Line and low voltage wiring
must be done in accordance with local codes or the National
Electric Code, whichever is applicable.
Power Connection
Max
Line voltage connection is made by connecting the incoming
Fuse/
line voltage wires to the "L" side of the contactor as shown in
HACR
Figure 21. Consult Tables 7a through 7b for correct fuse size.

208 Volt Operation
35
All residential 208-230 Volt units are factory wired for 230
40
Volt operation. The transformer may be switched to the 208V
45
tap as illustrated on the wiring diagram by switching the red
50
(208V) and the orange (230V) wires at the contactor terminal.
