OPERATING VOLTAGES
WARNING
USE EXTREME CAUTION WHEN CHECKING HIGH VOLTAGE.
Use a voltmeter, check the voltage at the outlet.
The reading must be within the minimums and maximums shown below for the operating voltage.

Operating Voltages
NOTE:
1. All 265 volt models must use subbase or hard wire kit.
2. Minimum branch circuit ampacity ratings conform to the National Electric Code. However, local codes should apply
if in conflict.
3. Minimum voltage on 230/208 volt models is 197 volts; maximum is 253 volts. Minimum on 265 volts is 238 volts;
maximum is 291 volts.
4. Overcurrent protection for all units without electric heaters is 15 amps. Overcurrent protection on 265 volt models
must be cartridge-style time delay fuses (included and factory installed on chassis).
5. Heating capacity and efficiency is based on unit operation without condensate pump. Unit automatically switches to
electric heat at 25° F outdoor coil temperature.
6. Total watts for 15,000 BTUH models; subtract 30 watts for PT*12*E**** and 70 watts for PT*07/09*E****.
7. Please specify 2-digit heater kW size to compete model number.
8. Total amps for 12,000 and 15,000 BTUH models; subtract 0.2 amps for PT*07/09*E****.

LCDI or AFCI Power Cords
- Underwrites Laboratories and the National Electric Code (NEC) now require power cords
that sense current leakage and can open the electrical circuit to the unit on units rated at 250 volts or less. In the
event that unit does not operate, check the reset button located on or near the head of the power cord as part of
the normal troubleshooting procedure.
