ELECTRICAL POWER CONNECTION
Field wiring to the unit must conform to and be grounded in
accordance with the provisions of the National Electrical
Code ANSI/NFPA No. 70 - latest edition, Canadian Electric
Code C22.1 Part 1 - (latest edition) and/or local codes. Elec-
trical wires which are field installed shall conform with the
temperature limitation for 63F/35C rise wire when installed in
accordance with instructions. Specific electrical data is given
on the furnace rating plate.
Provide a power supply separate from all other circuits. Install
overcurrent protection and disconnect switch per local/
national electrical codes. The switch should be reasonably
close to the unit for convenience in servicing. With the dis-
connect switch in the OFF position, check all wiring against
the unit wiring label. Also, see the wiring diagram in this
instruction.
Connect the power supply as shown on the unit wiring label
on the inside of the blower compartment door. The black fur-
nace lead must be connected to the L1 (hot) wire from the
power supply.
The white furnace lead must be connected to neutral. Also,
the green equipment ground wire must be connected to the
power supply ground.
Remove the screws retaining the wiring box cover. Route the
power wiring through the unit side panel with a conduit con-
nector or other proper connection. Make wiring connections,.
Replace the wiring box cover and screws. Refer to Figure
11.
An alternate wiring method is to use a field provided 2 x 4 box
and cover on the outside of the furnace. Route the furnace
leads into the box using a protective bushing where the wires
pass through the furnace panel.
NOTE: The power connection leads and wiring box on upflow
units may be relocated to the left side of the furnace. Remove
the screws and cut wire tie holding excess wiring. Reposition
on the left side of the furnace and fasten using holes pro-
vided.
NOTE: The furnace’s control system depends on correct
polarity of the power supply and a proper ground connec-
tion. Refer to the furnace control diagnostics section for
symptoms of reversed power supply polarity.
Use copper conductors only.
