MANUFACTURED HOUSING
In manufactured housing applications, the Code of Federal Regulations,
Title 24, Chapter XX, Part 3280.714 requires that supplemental electric
heat be locked out at outdoor temperatures above 40°F (4°C), except for
a heat pump defrost cycle. Refer to
with outdoor thermostat.
TRANSFORMER INFORMATION
Transformer is factory wired for 230V operation. For 208V
applications, disconnect the black wire from the 230V terminal on
transformer and connect it to the 208V terminal

HEATER STAGING
If electric heat staging is required, a multi-stage heating room thermostat
is required. Consult your equipment supplier for a suitable thermostat.
GROUND CONNECTIONS
NOTE: Use UL listed conduit and conduit connectors for connecting
supply wire(s) to unit to obtain proper grounding. Grounding may also
be accomplished by using grounding lugs provided in control box.
ELECTRICAL SHOCK HAZARD
Failure to establish uninterrupted or unbroken ground could result in
personal injury and/or death.
A160010A
According to NEC, NFPA 70, and local codes, the cabinet must have an
uninterrupted or unbroken ground to minimize personal injury if an
electrical fault should occur. The ground may consist of electrical wire
or metal conduit when installed in accordance with existing electrical
codes. If conduit connection uses reducing washers, a separate ground
wire must be used.
MINIMUM CFM AND MOTOR SPEED SELECTION
The fan speed selection is done at the motor connector. Units with or
without electric heaters require a minimum CFM. Refer to the unit
wiring label to ensure that the fan speed selected is not lower than the
minimum fan speed indicated.
A160011A
