Step 5 -- Complete Electrical Connections
Installation of wiring must conform with local building codes,
or in the absence of local codes, with the National Electric
Code ANSI!NFPA (American National Standards Institute/
National Fire Protection Association) 70, current editions.
Units must be electrically grounded in conformance with the
code. In Canada, wiring must comply with CSA (Canadian
Standards Association) C22.1, Electrical Code.
Electrical shock can cause personal injury and death. Dis-
connect power supply before making wiring connections.
There may be more than one disconnect switch. Tag all dis-
connect locations to alert others not to restore power until
work is completed.
All units must be wired strictly in accordance with the wir-
ing diagram furnished with the unit. Any wiring different
from the wiring diagram could result in personal iniury and
property damage.
Any original factory wiring that requires replacement must
be replaced with wiring material having a temperature rat-
ing of at least 221 E
Ensure supply voltage to the unit, as indicated on the serial
plate, is not more than 10% over the rated voltage or 10%
under the rated voltage.
Failure to follow these recommendations may result in
equipment damage.
This equipment in its standard form is designed for an elec-
trical supply of 208/230-1-60. Any damage to or failure of
units caused by incorrect wiring or voltage is not covered by
warranty.
Electric wiring must be sized to carry the full load amp
draw of the motor, starter, and any other controls that are used
with the unit. See Table 3 for electrical data.

After the pipe work is complete, the electrical supply can be
connected by routing the cable through the appropriate casing
holes or knockouts and connecting the supply and ground ca-
bles to the unit's power terminal.
Be sure the power wiring and control wiring do not cross, as
this might cause disturbance on the controls side. See Fig. 10
for wiring diagram.
NOTE: The indoor unit requires its own power supply. Indoor
units are not powered through outdoor units.
