• 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.
Select the proper supply circuit conductors in
accordance with tables 310-16 and 310-17 in the
National Electric Code, ANSI/NFPA No. 70 or tables 1
through 4 in the Canadian Electric Code, Part I, CSA
Standard C22.1.
• The power supply must be sized and protected
according to the specications supplied on the product.
• This air handler is factory-congured for 240 volt,
single phase, 60 cycles. For 208-volt applications, see
“208 Volt Conversion” later in this section.
• Separate openings have been provided for 24V low
voltage and line voltage. Refer to the dimension
illustration of specic location.
• This unit is provided with holes for conduit. Use
provided caps to seal holes not used.
• Typical unit wiring (as well as wiring of optional eld-
installed electric heat) is given in Figure 14. Refer to
the instructions provided with the electric heat section
for proper installation.
USE COPPER CONDUCTORS ONLY
WARNING
1. Disconnect all power supplies.
2. Remove the air handler access panel.
3. Route the eld supply wires to the air handler electrical
connection box.
4. Use UL-listed wire nuts to connect the eld supply
conductors to the unit black and yellow leads, and the
