Installation Clearances
Provide enough space around the unit
to allow unrestricted access to all
service points. Refer to unit space
clearance data for minimum required
service and free air clearances.
Observe the following points to insure
proper unit operation.
Refer to table 2 for reccomended
spacing.
a. Don't install the unit under low shield.
Keep discharge air freely.
Ground Level Mounting
The unit base should be adequately
supported and hold the unit near level.
Any ground level location must comply
with the required clearances. Place the
unit on a 102 mm cement support plate.
The support should extend 51mm
beyond the unit base channel at all
points. The unit and support should be
Isolated from any adjacent structure to
prevent possible noise or vibration
problem.
Important: Don't block discharge air.
This can result in warm air recirculation
through the coil.
b. Don't locate the unit in a position
where runoff water can drop into the fan
discharge openings.
c. Intake air can be supplied from 2
sides of unit.
Rooftop Mounting
If the unit is roof mounted, be sure the
structure is strong enough to support
the overall weight of the unit and all
accessories. Refer to Table 1 for unit
weight details.
Warning: Ensure the structure is strong
enough to support the gross weight of
unit and its accessories. Failure to do
will result in severe injury or death and
can seriously damage the unit and
building.
The unit should be elevated on a
horizontal, field-fabricated 102 mm steel
frame or 100 X 100 mm wooden
mounting frame. Complete the frame
and fix it firmly on the roof. The frame
must support a minimum of three of the
unit' s four sides and can span the roof
supports to distribute the load on the
roof.

Installation Consideration
For proper installation and operation,
check each of the following before
mounting the units.
a. Space Requirement and
Clearance
Allow adequate space for the unit and
free air or service clearance. See Figure
1a.
lnstallation, Limitation and
Important Recommendation
The general location of the air handler
is normally selected by the architect,
contractor, and/or buyer. For proper
installation, the following items must be
considered.
a. Available power supply must agree
with electrical data on component
nameplate.
b. Air handler shipped wired for 380-415
volt applications.
c. lf external accessories are installed
on the unit, additional clearance must
be provided.
d.All duct work should be properly
insulated to prevent condensation
and heat loss.
e.Refrigerant gas piping must be
insulated.
Caution
Properly insulate all refrigerant gas
piping to prevent possible water
damage due to condensation and to
prevent capacity loss and possible
compressor damage.
- It is recommended that the outline
drawings provided be studied and
dimensions properly noted and
checked against selected installation
site. By noting in advance which
knockouts are to be used, proper
clearance allowances can be made for
installation and possible future
service.
lf adding external accessories to the
unit, additional clearances must be considered
for the overall space needed.
Lifting Recommendation
Before preparing the unit for lifting, the
center of gravity should be determined
for lifting safety. Because of placement
of internal components, the unit weight
may be unevenly distributed.
Approximate total unit weight and
corner weights are given in Table 5.
(and Figure 2a, 2b)
Warning
On site lifting equipment must be
capable of lifting the weight of the unit
with an adequate safety factor. The use
of under-capacity lifting devices may
result in personal injury or death and
cause damage to the unit.
The crated unit can be moved using a
forklift of suitable capacity. For lifting
the unit into an elevated mounting
position, run lifting straps or slings
under the unit and attach securely to
the lifting device. Use spreader bars to
protect the unit casing from damage.
Test lift the unit to determine proper
balance and stability.
Caution
Use spreader bars to prevent straps
from damaging the unit. Install the bars
between lifting straps, both underneath
the unit and above the unit. This will

b. Location, Mounting and
Positioning
Before installing any unit make sure
proper preparation has been made at
each unit locating for piping and
electrical connections.
Figure 2a
Figure 2b
Horizontal Suspension
lf the air handler will be suspended, use
a suspension mounting kit to isolate the
unit from the structure. This is usually
accomplished through the use of spring
or rubber isolators. Mounting rods must
be field supplied. Isolator selection is
dependent upon total unit weight,
including accessories. Approximate
unit weights are provided in Table 5.
See Figure 2b (for horizontal
configuration) and see Figure 2a (for
vertical configuration).
Caution
Before hanging the unit on suspension
rods, reinforce the cabinet around the
knockouts, using a large washer inside
the cabinet. Washer should be between
the skin of the air handler and the nut
on the suspension rod.
Align holes (knockouts) in the cabinet
with structural supports and secure
suspensions rods to the structure, then
to the air handler cabinet. If knockout
locations do not permit proper
alignment with existing structure, it may
be necessary to field fabricate cross
members on existing structural beams.
Note
When other that bottom return is to be
used, side panel removed for return
duct installation, must be secured over
the bottom opening.
Auxiliary Drain Pan
A field fabricated auxiliary drain pan
should be installed under the unit for
all horizontal applications, and when air
handlers are installed above ceilings or
in other locations where condensate
overflow may cause damage. This drain
pan will eliminate any excess
condensation that may be due to
extreme humidity or an obstructed drain
in the primary drain pan. Drain lines
from this pan must be installed, but
should not be connected to the primary
drain line from the unit, isolate the
auxiliary drain pan from both the air
handler and the structure.
Positioning and Installation
The final position must be dictated by
required service access to unit, weight
distribution over structural supports,
and by the locations of electrical,
refrigerant and condensate drainage
connections. All refrigerant piping
connections are made inside the
cabinet. They may enter the cabinet
through factory provided knockouts.
Note
TTH/V 150~240
The air handler is designed so that
refrigerant piping can only from the
right hand side.
Caution
• Protect adjacent surfaces from heat
damage, when brazing in and around
the air handler.
• These air handlers are shipped with
a holding charge in the coil. Do not
bleed holding charge until refrigerant
lines ready to be connected.

TRANE ®
Unit Installation - Indoor Unit
On air handlers that will have refrigerant
lines entering the cabinet from the right
side, the bulb(s) should be attached to
the suction tube(s) inside the cabinet,
in the same manner as above,
approximately 10" from the right end of
the unit.
After attaching to the suction line(s),
either inside or outside of the cabinet,
wrap the cork impregnated insulation
around the bulb(s) and suction tube(s).
Refrigerant piping should then be
insulated.
Important
Ensure that the refrigerant lines passing
through the cabinet are not resting on
sharp sheet metal edges.

Structural Preparation for
Outdoor Unit
Holes must be made in the structure to
run refrigerant lines. For the majority
of ground-level installations, the holes
can be made in the header that rests
on top of the foundation. Alternatively,
these holes may also be made in the
foundation itself. On roof-mounted
units, refrigerant lines should enter the
building as close to the unit as possible;
preferably within 76 to 102mm of the
refrigerant connection on the unit, plus
a 152 mm (long radius) 90 degree ell
entering the building (See Figure 8).

Guidelines
a.Maximum recommended line
lengths: (per circuit)
Maximum linear length 200 Ft.
Maximum suction line lift 60 Ft.
Maximum liquid line lift 60 Ft.
e. Avoid creating large oil traps in
horizontal suction lines as this will
reduce oil circulating in the system
and may eventually lead to failure of
the compressor.
f. A small oil trap at the end of a
horizontal suction line before a long
vertical riser (of more that 4 meters)
has the advantage of assisting the
high velocity gas to carry the oil up
the vertical pipe.
b. Maximum allowable pressure drops
(R-22):

System Refrigerant Piping
Refrigerant Piping
Procedures (Outdoor Unit)
Each unit ships with a dry nitrogen. Due
to this, the charge has to be removed
and the entire system evacuated (at the
proper time) to avoid possible
contamination.
1. Remove the compressor service
access panel.
2. Find the liquid and suction line
service valves. Check that the
piping connection stubs on the
valves line up properly with the
holes in the unit cabinet.
3. Puncture the seal cap on the service
connection stubs to release
remaining refrigerant and nitrogen
(See Figure 9)
5. Cut, fit and braze tubing, starting at
the outdoor unit and work toward the
indoor unit.
Note: Use long radius ells for all 90-
degree bends. All brazing should be
done using 14 to 56kPa dry nitrogen
purge flowing through the pipe being
brazed (See Figure 10).
Caution: Wet-wrap all valves and
protect painted surfaces from excessive
heat. Heat can damage system
components and the units finish.
Note: Install a pressure-regulating valve
between the nitrogen source and the
gauge manifold (See Figure 10).
Unregulated pressure will damage the
unit components.
Leakage Test
Figure 9
Warning: Do not heat the seal caps
unless they have been punctured. If
caps are intact, application of heat may
generate excessive pressure in the
connection stub, causing personal
injury or death due to rupturing of
components and damage to the service
valve.
After the brazing operation of refrigerant
lines to both the outdoor and indoor unit
is completed, the field-brazed
connections must be checked for leaks.
Pressurize the system through the
service valve with dry nitrogen to
1.4MPa. Use soap bubbles or other
leak-checking methods to ensure that
all field joints are leak free. If not,
release pressure, repair and repeat leak
test (See Figure 10).
4. Heat and remove the seal cap and
open the service valve slowly to
release the Nitrogen from the unit.
Caution: Do not remove the seal caps
from refrigerant connections before unit
prepared to braze refrigerant lines to the
connections. Excessive exposure to
atmosphere may allow moisture or dirt
to contaminate the system, damaging
valve seats and causing ice format ion
in system components.

Charging Procedures
Unit Evacuation
1. Evacuate the unit after leakage test.
2. Attach appropriate hoses from
manifold gauge to suction and liquid line
charging port (See Figure 11).
Refrigerant Line Insulation
and Isolation
Insulate the suction line and refrigerant
tubes together, and also insulate liquid
lines exposed on extreme temperatura.
Insulate liquid and suction line
separately and isolate them from each
other. Isolate all refrigerant tubes from
the structures and air ducts.
Note: Isolate the refrigerant tubes from
the building to avoid possible noise and
vibration.
Figure 11
Note: Unnecessary switching of hoses
can be avoided and complete
evacuation of all lines leading to sealed
system can be accomplished with
manifold center hose and connecting
branch hose to a cylinder of refrigerant
and vacuum pump.
Figure 12
3. Connect the center hose of manifold
gauge to a vacuum pump.
4. Evacuate the unit to hold a 46Pa
vacuum.
5. Close the valve to the vacuum pump
and observe the gauge. If gauge
pressure rises above 66Pa within a
minute, it indicates that the vacuum
is not completed or the system has a
leak.
6. If the gauge pressure does not rise
above 66Pa within a minute, it
indicates that the vacuum is
completed.
