1.5.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
Failure to heed the following will result in injury or death.
l
Deactivate power while routing wiring to control board.
l
Follow all National Electric Codes (NEC) and/or State and Local guidelines.
WARNING
Failure to heed the following may result in injury or death.
l
The information contained in this section is intended for use by qualified technicians, familiar with electrical
service-industry safety standards and methods.
Example of heat pump
transformer
(Varies between models)
1. Turn heat pump on by adjusting the thermostat to call for heating . 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 -
l
If more than one voltage is shown on the equipment’s data plate, the factory default setting is
usually the higher voltage on the transformer.
l
As an example, a "208/230" voltage will be set to "240" from the factory.
