l
service-industry safety standards and methods.
NOTICE
Setting a voltage other than what is listed on the heat pump's data plate can damage equipment and is not covered
l
under warranty.
If a three-phase unit fails to operate at start-up, the orientation of the line voltage "field" wiring may need to be
adjusted.
Three-phase models are equipped with a Three-Phase Monitor or the ICM Digital Three-Phase Monitor.
l
Units equipped with the ICM Digital Three-Phase Monitor will display a "Back Phase Rev" fault code on the
l
phase monitor display.
There is no display on the standard three-phase monitor.
l
The phase monitor is located inside the electrical panel.

1. Deactivate power to the unit. Confirm that power is off to all three legs
using an electrical test meter set for the correct voltage.
2. Switch position of the incoming power wires at each leg as follows, re-
connect power and attempt to restart the unit. If the unit fails to start,
disconnect power. Verify off and proceed to the next leg.
Switch incoming power wires at L1 and L2 on the line side to the
l
contactor.
Switch incoming power wires at L1 and L3 on the line side to the
l
contactor.
Switch incoming power wires at L2 and L3 on the line side to the
l
contactor.
