HIGH VOlT ElECTRICAl WIRING
(SEE ThE aPPROPRIaTE aIR haNDLER SECTION FOR
SPECIFIC WIRING INFORMaTION.)
All wiring should be in accordance with the National Electric
Code (NEC) and the local building codes.
1. Inspect the existing wiring for any deficiencies
such as cut or frayed wires. Replace such wiring
if found.
2. Check the unit rating plate for circuit ampacity and
breaker or fuse size.
Use only HACR type break-
ers.
Select the proper wire for the ampacity rating.
3. Each unit must have a separate branch circuit pro-
tected by a fuse or breaker. Refer to the unit rating
plate for the proper wire and breaker or fuse size.
4. Connect the power wire to Black (L1) and the other
wire to Red/White (L2) at the power connector loca-
tion. Connect the ground wire to the ground lug or
lead at the same location in the control box.
IMpORTANT: When wiring the WCp 18–36 only:
If the job site voltage is 208V, the WCp high-low
fan speed switch may be rewired to increase air
speed. Replace the black and red fan motor wire
connections with the blue and orange fan motor
wires respectively.
See unit wire diagram for specific details.
ITEMS FOR CONSIdERATION
Determine the best location for mounting the unit for
room air circulation.
Determine how power wire (high and low voltage)
condensate drainage, and water supply piping may
be run to and from unit. Knockouts on the air handler
may be used for this purpose.
Serviceability should be considered when locating
the unit. The cabinet service panels must be able
to be removed without obstruction.
CCp -
units can be equipped with hot water coil.
Unit mount control panel
(standard on and WCP
optional on CCP) includes:
• ¾” backlit LCD display
• Adjustable operational range from 55° F to 95° F (in
one-degree increments)
• 60 second fan purge
• Freeze protection
• Audio feedback on control setting changes
Fan operation:
Auto (cycling), high and Low (constant)
• Dry Mode (operates cooling and electric heat simul
-
taneously to remove humidity when optional electric
heat is selected)
• Test Operation for ease of testing after installation (all
timers reduced)
• Non-volatile Backup Memory (control settings main
-
tained indefinitely during power outages)
• 24V
Low Voltage Transformer
OpTIONAl CONTROlS & COMpONENTS
• Infrared hand held remote control
• Condensate pump (field or factory installed)
• Chilled water control valve (field installed)
• Wiring for normally closed/power open valve (24V
AC, 20VA max. or 8VA max. on units with conden-
sate pumps)
CONTROlS ANd COMpONENTS
Factory Installed or Supplied
IMpORTANT:
Unit mounted controls are fully func
-
tional without the hand-held remote. See page 5
COMMON TO All AIR HANdlERS

NOTE:
On units rated 208/230V, the primary side of
the transformer is factory wired for 230V. For a 208V
power supply, the transformer tap must be changed
from orange to red. Refer to the wiring diagram located
on the unit.
• Open wire electric heaters in 3 sizes
(factory
installed ONLY)
with automatic reset high tem-
perature cutout and redundant high temperature
fuse link
• Hydronic heat coil with sweat connections (consult
factory) CCP only
• 24V wall thermostat compatibility
• 24V thermostat
