Any original factory wiring that requires replacement must
be replaced with wiring material having a temperature
rating of at least 105 C.
Ensure supply voltage to the unit, as indicated on the serial
plate, is not more than 10% over the rated voltage or 10%
under the rated voltage.
Failure to follow these recommendations may result in
equipment damage.
This equipment in its standard form is designed for an
electrical supply of 208/230-1-60. Any damage to or failure of
units caused by incorrect wiring or voltage is not covered by
warranty.
Electric wiring must be sized to carry the full load amp
draw. See Table 17 for main unit electrical data and Table 18
for sub unit electrical data.
