WARNING
Electric shock hazard! - Disconnect all
power supplies before servicing.
Replace all parts and panels before
operating.
Failure to do so can result in death or
electrical shock.
WARNING
ELECTRIC SHOCK HAZARD
Can cause injury or death.
Foil-faced insulation has conductive characteristics
similar to metal. Be sure there are no electrical
connections within a 1/2" of the insulation. If the foil-
faced insulation comes in contact with electrical voltage,
the foil could provide a path for current to pass through
to the outer metal cabinet. While the current produced
may not be enough to trip existing electrical safety
devices (e .g. fuses or circuit breakers), the current can
be enough to cause an electric shock hazard that could
cause person al injury or death.
•
All field wiring must be done in accordance with National
Electrical Code, applicable requirements of UL and local
codes, where applicable.
•
Electrical wiring, disconnect means and over-current
protection are to be supplied by the installer. Refer to
the air handler rating plate for maximum over-current
protection, minimum circuit ampacity, as well as
operating voltage.
•
The power supply must be sized and protected
according to the specifications supplied on the product.
•
This air handler is factory-configured for 240 volt, single
phase, 60 cycles. For 208-volt applications, see "208
Volt Conversion" later in this section.
•
For optional field-installed electric heat applications,
refer to the instructions provided with the accessory for
proper installation.

Making Electrical Connections
208 VOLT CONVERSION
1. Disconnect all power supplies.
2. Remove the air handler access panel.
3. Using the wiring diagram located on the unit access
panel as a reference, move the 2 connected black
transformer leads from the 240 volt terminal on the
transformer to the 208 volt terminal on the transformer.
Electrically ground air handler. Connect
ground wire to ground terminal marked
"GND".
Failure to do so can result in death or
electrical shock.
