1.3.d Verifying Transformer Setting (Select Units)
Transformer voltage must be confirmed and set correctly depending on the measured voltage found on the
site. Incorrect settings may cause heat pump damage. The following procedure will allow the installer to
set the heat pump's transformer for the appropriate site voltage.
DANGER
Deactivate power while routing wiring to control board.
l
Follow all National Electric Codes (NEC) and/or State and Local guidelines.

WARNING
The information contained in this section is intended for use by qualified technicians, familiar with electrical
l
service-industry safety standards and methods.
1. Turn heat pump on by adjusting the thermostat to call for heating or cooling.
If more than one heat pump is on-site, turn them all on. Allow time for all
heat pump compressors to activate.
2. Measure the running site voltage.
3. Confirm transformer tap is set for the measured site voltage. If more than
one voltage tap is shown, select the voltage nearest to the running site
voltage.
PLEASE NOTE -
If more than one voltage is shown on the equipment's data plate, the factory default setting
l
is usually the higher voltage on the transformer.
As an example, a "208/230" voltage will be set to "240" from the factory.
