3.4.e Verifying Transformer Setting
Transformer voltage settings 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 pumps transformer for the appropriate site voltage.
WARNING - Failure to heed the following may result in injury or death.
The information contained in this section is intended for use by qualified electrical installation technicians,
l
familiar with electrical service-industry safety standards and methods.
CAUTION - Failure to heed the following may result in equipment damage.
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.
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. Final
adjustments must be made with all heat pumps running.
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 is usually the higher voltage on the transformer. As an example, a
"208/230" voltage will be set to "240" from the factory.
3.4.f Three-Phase Adjustment
If a three-phase unit fails to operate at start up, the orientation of the line voltage "field" wiring may need to
be adjusted.
WARNING - Failure to heed the following may result in injury or death.
The information contained in this section is intended for use by qualified electrical installation technicians,
l
familiar with electrical service-industry safety standards and methods.
CAUTION - Failure to heed the following may result in equipment damage.
Setting a voltage other than what is listed on the heat pump's data plate can damage equipment and is not
l
covered under warranty.
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.
