14.2 Make Electrical Connections
STEP 1
- Route High Voltage wiring to unit.
STEP 2
- The conduit entry point is located on the top
of the unit when in the Upflow configuration. Drill a
hole for the desired conduit size (up to 3/4””) on units
without a plug. A locating target is identified on the
unit.
Note: If a hole is already present, remove the plug
from the entry point and use as is.
STEP 3
- Route conduit (if used) to the entry point and
connect.
1. Use one hand to secure the conduit nut from inside of
the heater compartment.
2. Connect field supplied conduit (up to 3/4”) to conduit nut.
Note:
Reducing bushings may be required for your
application.
STEP 4
- If an electric heater IS NOT being installed,
remove the pigtail harness from the documentation
pack and connect it to the plug on the inside of the
Heater Compartment in the cabinet.
If an electric heater IS being installed, see the Install-
er’s Guide shipped with the electric heater.
Connect L1, L2, and ground wiring to pigtail harness
in Heater Compartment using wire nuts. The incoming
ground wiring will mate up with the green wire shown
