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 WHP 18–36 only: If
the job site voltage is 208V, the WHP high-low fan
speed switch must be rewired. 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. Locate outdoor and indoor
units as close together as possible.
Determine how power wire (high and low voltage)
condensate drainage, and refrigerant or water sup-
ply piping (for chilled water units) may be run to and
from unit. Knockouts on the air handler may be used
for this purpose.
FHP, WHP, and CHP ONLY
- Ensure that intercon-
nect tubing is within the maximum allowable length
of 100’ including a maximum 35’ lift.
Serviceability should be considered when locating
the unit. The cabinet service panels must be able
to be removed without obstruction.
FCP/FHP/CCP/CHP -
units can be equipped with
hot water coil.
Unit mount control panel
(standard on FHP/FCP
and WHP/WCP optional on CCP/CHP) includes:
• ¾” backlit LCD display
• Adjustable operational range from 55° F to 95° F (in
one-degree increments)
• Anti-short cycle compressor protection
• Minimum compressor run time
• 60 second fan purge
• Freeze protection
• Audio feedback on control setting changes
• Universal control board for straight cool or heat pump
condenser operation
• Two-stage heating w/optional electric heat and heat
pump condenser
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 eliminated)
• 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)
• 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) FCP/FHP and CCP/CHP only
• 24V wall thermostat compatibility
• 24V thermostat
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.
