See submittal drawings for unit configurations, dimensions,
clearances, and pipe connections. Refer to unit wiring label for
all electrical connections; follow NEC (National Electrical
Code) and local codes.

PREINSTALLATION
Unpack and Inspect UnitsRemove shipping wraps
from all units. Check the shipment against shipping order. If
shipment is damaged or incomplete, file claim with transportation company and advise Carrier immediately.
Protect
Units From Damage -- To maintain warranty, protect units against adverse weather, theft, vandalism,
and debris on jobsite. Do not allow foreign material to fall into
drain pan. Prevent dust and debris from being deposited on
motor and fan wheels.
If the equipment is stored for any length of time before installation, it should remain in its shipping container in a clean,
dry, and climate controlled area.

Prepare Jobsite

for Unit Installation -To save
time and to reduce the possibility of costly errors, set up a complete sample installation in a typical room at jobsite. Check all
critical dimensions such as pipe, wire, and duct connection
requirements. Refer to job drawings and product dimension
drawings as required. Insmlct all Wades in their part of the
installation.

Manufacturer reserves the Hght to discontinue, or change at any 11me,specifications or designs wi_out notice and without incurring obligatlot_.s.

INSTALLATION

Units must be installed level and plumb. Failure to do so
may result in excessive vibration and/or premature failure.

Placing Vertical
l.

Units in Position
Select the unit location; ensure that service clearance is
provided. Allow enough grille clearance to maintain
unrestricted airflow. See submittal drawings and Fig. 1
and 2 for dimensions.

2. Make sore wall behind unit is smooth and plumb; ff
necessary, install furring strips on walls with irregular
surfaces or mullions. Furring strips must be positioned
behind mounting holes in unit. Fasteners, furring strips,
and other seals (if required) must be field supplied.
3. Remove all wall and floor moldings from behind the unit4. Move unit into position. Unit must be snug against wall
and furring strips.

5. Adjust unit leveling legs so unit is level. Unit must be
level for proper operation and condensate drainage.
6. Using field-supplied fasteners, reach into unit and attach
unit to the wall using the 3/4 in. mounting holes in the
back panel.
7. Protect the unit from jobsite debris. Do not allow foreign
material to fall into drain pan. Prevent dust and debris
from being deposited on motor or fan.

Placing Horizontal

Units

in Position

l. Select the unit location; ensure that service clearance is
provided. Allow enough grille clearance to maintain ura'estricted airflow. Make sure that ceiling is able to support
the weight of the unit. See Fig. 3-5 for nominal unit weight.
See submittal drawings and Fig. 3_5 for dimensions.
NOTE: See page 23 for additional requirements for units
ducted to multiple openings.
2. Ensure that bottom panels have been removed from unit_
When unit is lifted, access to the 3/4in. mounting holes is
through the bottom of the unit- Hanger rods and fasteners
and other required hardware must be field supplied.
3. Using a forklift or other mechanical lifting device, raise
the unit to the mounting position. If forklift or other
lifting device is likely to contact a painted wall surface,
protect the surface as necessary.
4. Use rods and fasteners to suspend the unit at the mounting
holes on the top of the unit. The unit must be suspended at
the 3/4in. mounting holes; do not use any other locations.
5. If desired, install field-supplied vibration isolators. Adjust
isolators so unit is uniformly suspended and pitched.
6. To ensure proper drainage and operation, ensure unit is
level and tighten all fasteners. DO NOT mount the unit
on a slope. Pitch of horizontal suspended units can
change after coil is filled; recheck after filling coil.
7. Protect the unit from jobsite debris. Do not allow foreign
material to fail into drain pan. Prevent dust and debris
from being deposited on motor or fan.

Make Piping Connections -- Access to piping is
available through the access panels at the front, top, or end of
the vertical unit (horizontal access from bottom or side). Route
piping through the pipe tunnel or the unit's back panel or floor
panel. Metal blank-off panels must be trimmed to complete
piping installation. All piping connections must be performed
by qualified personnel in accordance with local and national
codes.
DRAIN CONNECTIONS
-- Condensate drain connections
are located on each end of the drain pan near the bottom of the
unit. Condensate drain line must be 3/4 in. copper tubing,
.galvanized pipe, PVC or similar plastic pipe. Install drain line
m accordance with all applicable codes. Insulate the drain
line to prevent sweating. See Fig. 6 for typical drain trap
construction.
Units with cooling coils require traps to prevent air from
entering the condensate fitting and preventing proper drainage.
Drain must flow downhill from the unit a minimum of 1/_in.
per ft. Drain must be flee and clear at all times.

SENSING BULB (CLAMPED TO
SUCTION LINE AND INSULATED)

__

Insulate drain lines to prevent condensate. Care must be
taken to avoid interference with control panel on left side
drain.
WATER SUPPLY/RETURN CONNECTIONS -- Install pipmg in accordance with all apphcable codes. All piping must be
supported separately from coils.
Water supply must be connected so that entering water is on
leaving-air side of coil. See the connection labels on the unit to
locate the inlet. Coils must be adequately vented to prevent air
binding. Be sure valves are in proper operating position and are
easily accessible for adjustment.
If coil and valve package connections will be made with a
solder joint, care should be taken to ensure that components in
the valve package are not subjected to high temperatures which
may damage seals or other materials. Many 2-position electric
control valves are provided with a manual operating lever. This
lever should be in the OPEN position during all soldering
operations.
If coil connection is made with a union, the coil side of the
union must be prevented from turning (it must be backed up)
during tightening. Do not overdghten? Overtightening will distort (egg shape) the union seal surface and destroy the union
NOTE: A freezestat is factory-installed when a hot water/steam
coil is installed.
STEAM CONNECTIONS
-- On units with steam heating
coils, the maximum steam pressure applied to the unit should
never exceed 10 psig (operating pressure 6 psig).
DIRECT EXPANSION REFRIGERANT PIPING -- Use the
condensing unit manufacturer's recommended line sizes and
requirements. Perform leak test using nitrogen. Evacuate and
charge per recommended heating, ventilation, and air conditioning (HVAC) procedures and all applicable codes. Insulate
suction line after leak test up to the coil section end plate for
correct operation and to ehminate sweating. Use refrigerantgrade copper lines only. The unit is NOT to be apphed as a
heat pump.
See Fig. 7 for refrigerant piping connections with recommended locations for the thermostatic expansion valve (TXV)
and sensing bulb.
HYDRONIC COIL PIPING -- When all joints am complete,
perform hydrostatic test for leaks. Vent all coils at this time.
Cheek interior unit piping for signs of leakage from shipping
damage or mishandling. If leaks are found, notify a Carrier
representative before initiating any repairs. Release trapped air
from system (refer to Make Final Preparations section).

LIQUID LINE

NOTE: FollowTXV manufacturer's
instructions.
Fig. 7 -- Typical TXV (Thermostatic
Valve) Installation

Expansion

All water coils must be protected from freezing after initial
filling with water. Even if system is drained, unit coils may
still have enough remaining water to cause damage when
exposed to temperatures below freezing.
Following the hydrostatic test, insulate all piping up to the
coil section end plate to prevent sweating.
To ensure compliance with building codes, restore the structtue's original fire resistance rating by sealing all holes with
material carrying the same fire rating as the structure.
Make Electrical
Connections -- Refer to unit serial
plate for required supply voltage, fan and heater amperage, and
required circuit ampacities. Refer to unit wiring diagram for
unit and field wiring. See Tables 24 for electrical data.
All input power wiring connections are accessed through
the electrical panel on front right-hand side of the unit. Use the
openings that am for the piping connections. See the dimensional drawings Fig. 1-5 for electrical box connections.
The fan motor should never be controlled by any wiring or
device other than the factory-supplied switch or thermostat/
switch combination unless prior factory authorization is obtained. Fan motor may be temporarily wired for use during
construction only with prior factory approval and only in strict
accordance with the instructions issued at that time.
All electrical connections should be made by qualified personnel and be in accordance with governing codes and ordinances. Any modification of unit wiring without factory authorization
will invalidate all factory warranties and nullify any agency listings. See Fig. 8A and 8B for typical wiring connections for basic
unit with CCN (Carrier Comfo_ Network®) controls.

Actuators (Field-Supplied) -- Field-supplied actuators
must be mounted on l/z in. diameter damper shafts.
