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
Line voltage connection is made by connecting the incoming
line voltage wires to the “L” side of the contactor as shown
in Figures 21a through 21c. Consult Tables 8a through 8c for
correct fuse size.
208-230 Volt Operation
Verify transformer tap with air handler wiring diagram to
insure that the transformer tap is set to the correct voltage,
208V or 230V.
