HIGH VOLTAGE COMPARTMENT
Required Transformer Line Side Leg Change for 208 Voltage
The high voltage side of the 24 volt transformer must be rewired for 208 voltage. The orange 240 volt
lead should be swapped with the unused red 208 volt lead connected to the line side of the main contactor.
If the transformer is not rewired, the transformer will not produce an adequate amount of voltage to
operate the contactor coils in the various relays of the heater. This can cause intermittent contact and
damage to the compressor and contactors. Trace the orange wire to the terminal board, remove it and
replace it with the red wire. Cap and secure the orange wire.
NOTE: If the unit has the factory optional dual thermostat kit and motorized plumbing valve kit, you
must rewire the transformer on the motor valve kit as well. Damage due to improper low voltage instal-
lation is not covered under the warranty.
Always review the wiring schematic shipped with the heater located inside the heaters electrical
compartment, since it may have changed after this manual was printed ! Note 3 phase specifica-
tions available upon request @ 239-768-1555.
