Install low voltage wiring from outdoor to indoor unit and from
thermostat to indoor unit as illustrated.
HIGH VOLTAGE / GROUND WIRES
Any excess high voltage field wiring should be trimmed and
secured away from any low voltage field wiring. To facilitate a
conduit, a cutout is located in the bottom of the control panel.
Connect conduit to the control panel using a proper conduit
fitting.
CONTROL WIRING
NOTE — Wire tie provides low voltage control wire strain relief and to maintain
separation of field installed low and high voltage circuits.
NOTE — For proper voltages, select thermostat wire (control wires) gauge per
table below
.
NOTE — Do not bundle any excess 24VAC control wires inside control panel.
A
Run 24VAC control wires through hole with grommet and secure
with provided wire tie.
B
Make 24VAC thermostat wire connections. Locate the two wires
from the contactor and make connection using field provided wire
