Unit Installation
Installation Considerations
For proper installation and operation,
check each of the following before
mounting the units:
1. Allow adequate space for the unit
installation and service clearances.
For servicing and routine
maintenance, provide access to
the unit through removable panels
in the ceiling.
2. Before installing any unit make
sure proper preparation has been
made at each unit location for
piping and electrical connections.
3. If adding external accessories to
the unit, additional clearance must
be considered for the overall space
needed.
4. Check the supporting structure
(ceiling) should be strong enough
to support unit weights. All units
must be mounted level to assure
proper drainage and operation.
5. Ducting connected to units should
not exceed the external static
pressure rating of the unit.
6. Condensate protection for the
chilled water valves and piping
must be provided by installer
should be located under the valves
or else the valves and piping
should be throughly insulated.
Note: The general location of the Fan
Coil Unit is normally selected by the
architect, contractor, and/or buyer.
For proper installation, the following
items must be considered.
Installation Procedure
To proper installation procedure, Trane
HFCC/HFCD Chilled Water Fan Coil
follow these steps:
Coil Connections
Coil connection for HFCC model is 5/8
inch, HFCD model is 3/4 inch copper
tube. To complete piping connections,
attach the water pipe to the coil
connection at header. The water inlet
is on lower tube and the water outlet is
on upper tube of the header. Coil
connection size and coil connection
locations are given on dimensional
data. For coil connection, as shown in
Figure 1.
Connecting the unit with brazing
procedure
To braze the copper tube, use a
coupling between the copper tube of
Fan Coil Unit and water pipe as
shown in Figure 2.
Note: Before brazing a copper tube to
a solder coupling or a copper tube to
an expanded tube, do not forget to
keep them tight.
Condensate Drain Connections
1/2 inch PVC pipe (or flexible pipe)
connection can be used as a drain
line. Attach the drain line to the drain
connection with tape-sealant to
prevent leakage. To conveniently drain
the system, the drain piping must slant
downward, with a slope of at least
1:50 to prevent leakage. Figure 3 show
the unit in the ceiling mounted
position.
There should be no water traps in the
drain system. Avoid putting the end of
the drain pipe in water and the drain
pipe should run straight down the wall
to a level where the run off will not
stain the wall.
Note: When the drain pipe is placed in
the room, should insulate the pipe with
foam polyethylene to avoid damage to
the ceiling or furniture.
Mounting
The Trane model HFCC/HFCD units
are designed to be suspended from
the ceiling on threaded rods furnished
by the installer. Holes are provided at
the top of the units, see dimensional
data for cutout dimensions and
locations.
1. Install the suspension rods or other
suspension devices that must be
provided by installer.
2. Put the upper W 3/8" nuts and W
3/8" lock washers on suspension
rods to prevent unit from upward
tilting during unit operation or duct
installation, as shown in Figure 4
Typical Installation.
3. Hoist the unit into position. See
dimensional data for unit weights.
4. Put on the lower W 3/8" lock
washers and then 3/8" nuts to
secure the unit, as shown in
Figure 4, Typical Installation.
5. Level the unit casing to avoid poor
condensate drainage by adjusting
lower nuts up/down, and then
tighten the upon nuts.
Caution: Level the unit by checking
on the unit casing. Do not use the coil
or drain pan for leveling as they are
pitched to provide proper drainage.

Unit Installation
Duct Connections
Minimum 24 gauge galvanized sheet
metal duct (supplied by the installer)
can be attached to duct collars
provided at the unit air outlet and
inlet, see Figures 6 for duct collar
dimensions. To attach, slip the duct
over the outlet collar and fasten the
duct and collar together with screws.
Field-supplied transition fittings
should be used in installations
where unit duct collars do not match
discharge air-grille collars.
Two approaches can be used to
attach an air supply chamber and
flexible ducts. One approach is to
remove the unit outlet collar, slip the
collar into flexible duct and then
attach the duct and collar by fastening
the screws on two vertical sides of
collar, as shown in Figure 5, Duct
Work - A.
The other approach is to slip the duct
over the unit outlet collar and then
fasten the duct and collar together
with screws or rivets, as shown in
Figure 5, Duct Work - B.
A return duct can be attached to the
return air collar provided at the unit. To
attach, slip the return duct over the
return air collar and fasten the duct
and collar together with screws.
Note: All ductwork should be properly
insulated to prevent condensation
installation site.
Electrical Connections
Check the unit nameplate for
electrical rating. Be sure wiring is
done according to local codes and
wiring diagrams and available power
supply must agree with electrical
data on component nameplate.
Available power supply must be
compatible with electrical
characteristics specified on
component nameplates.
For wiring and installation, refer to the
wiring diagram decal on each unit.
Caution: Use only copper conductors
for wiring connections. Unit terminals
are not designed to accept other
types of wiring. Aluminum or other
conductors may cause overheating
and unit damage.
Note: The manufacturer will accept no
responsibility for problems caused by
unauthorized changes in the internal
wiring.
Tools required for installation
(not supplied)
1. Standard screwdriver
2. Phillips head screwdriver
3. Knife or wire stripper
4. Tape measure
5. Level
6. Hole saw or keyhole saw
7. Drill
8. Adjustable wrench
9. Torque wrench
10. Anchor bolts for ceiling mounting
Caution: Check local electrical codes
and regulation before buying any wire.
Also check for any specific wiring
instructions or limitations.

Installation Checklist
The following checklist is provided as
an abbreviated guide to the detailed
installation procedures given in this
manual. Complete this checklist once,
the unit is installed to verify that all
recommended procedures have been
accomplished before the system is
started.
Caution: Verify that the unit electrical
power is disconnected.
• Inspect all fields wiring connections.
All connection should be clean and
tight.
• Inspect unit ground connection.
Ground must comply with all
applicable codes.
• Unit casing is level. Remove any
tools or debris found in or near
the unit.
• Inspect duct outlets. Ductwork
connections are completed and
outlets must be open and
unrestricted.
• Coil connections are completed
and tight.
• Condensate drain pan connections
must be tight and drain
unrestricted.
• Inspect fan assembly to insure all
moving parts move freely.
• Inspect unit for proper filters,
securely installed. All cabinet
panels must be secured.
Caution: Disconnect electrical power
sources and secure in disconnected
position before servicing the unit.
Failure to do so may result in personal
injury or death from electrical shock.
Coil Venting
When water is first introduced into a
coil, air is sometime trapped in the
coil tube. This trapped air has a
tendency to collect at the highest
point in the coil. When there appears
to be air trapped in the coil, resulting
in “bubbling” or “clanking” noises
within the unit. Therefore, a manual air
vent is installed at the highest point of
the header as shown in Figure 6.
To release air from the manual air vent
by rotating the knob. A pair of pliers
can be used if the knob is too tight to
turn by hand. Turn knob counter
clockwise 1-2 turns and allow air to
flow out of the air vent until a steady
stream of water appears. Then
retighten knob.
