SAFETY WARNING
Only qualied personnel should install and service the equipment. The installation, starting
up, and servicing of heating, ventilating, and air-conditioning equipment can be hazardous and
requires specic knowledge and training. Improperly installed, adjusted or altered equipment by
an unqualied person could result in death or serious injury. When working on the equipment,
observe all precautions in the literature and on the tags, stickers, and labels that are attached to
the equipment.

Important Notice
Refrigerant Emission Control
Gas conservation and emission re-
duction should be accomplished by
adhering to operational and servi-
ce procedures recommended by
Trane, with special attention to the
following:
The refrigerant used in any type of
AC equipment must be always re-
covered and/or recycled for reuse,
reclaimed or completely destroyed
after being removed from the unit.
Never release the refrigerant to
the atmosphere.
Always consider the possibility of re-
cycling or reprocessing the refrige-
rant before starting the reclaim pro-
cess by any method.
The ARI 700 Standard covers ques-
tions about recovered refrigerant
and acceptable quality.
Use only approved and safe cylin-
ders. All applicable safety and shi-
pping standards must be met during
the transportation of refrigerant con-
tainers.
Recycling equipment should be
used to minimize emissions during
the transfer of refrigerant gas. Alwa-
ys use methods that generate the
lowest possible vacuum during the
recovery and condensation of refri-
gerant into the cylinder.

Unit Inspection
After the unit is delivered at the job
site:
- Verify that the nameplate data mat-
ches the data on the sales order, in-
voice and shipping documents (inclu-
ding electrical data).
- Verify that the power supply matches
the unit nameplate specications.
- Inspect the unit carefully for any
shipping damage.
If any damage or material shortage
is found it must be reported imme-
diately to the carrier. Specify the
type and extent of the damage on
the carrier’s delivery receipt before
signing.
- Notify Trane and/or the contrac-
tor about the damages and actions
to repair the unit. Do not attempt to
repair the unit until the damages are
inspected.
Storage
If it is not possible to install the unit
after delivery, it should be stored in
a safe location, protected from the
weather and other damages. Impro-
per equipment storage or handling
will void the equipment warranty.
Instructions for proper installa-
tion
Please consider the following items
required for proper installation befo-
re placing the unit at the mounting
location:
Unit Inspection
- The mechanical room should be
provided with proper lighting for ser-
vicing and maintenance.
- Make sure that the oor or founda-
tion is levelled, solid, and sufcient
to support the unit and accessory
weights. Level or repair the oor be-
fore positioning the unit.
- Provide the units with rubber pads
or vibration isolators.
- Install the hydraulic components
required to drain the water from the
condensate tray.
- Allow minimum recommended cle-
arances for routine maintenance
and service (see page 20).
- The same clearances should be
observed in case of several units to-
gether or condensing units.
- Provide electrical installation. The
unit has electrical inputs on both si-
des.
- Provide enough clearance to ac-
cess piping and remove covers.
The power supply must comply with
local codes and/or NEC.
- The contractor should provide and
install the refrigeration piping - both
for the liquid line and the suction
line - in order to interconnect evapo-
rator and condensing units.
General Safety
The Trane equipment is de-
signed for safe and re-
liable operation, as long
as units are operated according to
the applicable safety rules. The sys-
tem uses electrical and mechanical
parts, as well as gas pressures, that
may injury people or damage the
equipment if safety rules are not
followed. Therefore, the installation,
start-up and maintenance of this
equipment must be performed only
by qualied personnel or personnel
approved by Trane. Follow all safe-
ty standards related to the task and
warnings on unit labels, and always
use proper tools and equipment.
Hazard Identication
WARNING!
!
Warnings appear at appropriate
intervals and sections throughout
this manual to warn operators
and service personnel about a
potentially hazardous situation
which MAY result in serious injury
or equipment damage if safety
rules are not met.
CAUTION:
!
Cautions appear at appropriate
intervals and sections throughout
this manual to warn operators
and service personnel about a
potentially hazardous situation
which may result in damage to
the equipment and/or environ-
ment.

Transport and
Handling
Handling and Displacement Ins-
tructions
Proceed as follows to transport and
handle the unit:
1. Check the manual or nameplate
for the actual equipment weight.
2. For all units, place lifting cables
or chains under the skid. Other lif-
ting methods may cause serious in-
juries or equipment damage.
3. Do not allow chains, slings or ste-
el cables to touch the unit in order
to avoid damages or accidents. Use
suitable spreader bars as shown in
the gure.
4. The module packaging material
should only be removed after the
unit is placed at the nal mounting
location. Take proper care while
handling the equipment.
5. During transportation, do not
swing the unit more than 15º (fte-
en grades) in relation to the vertical
position.
6. Always test-lift the unit to ensure
proper balance and stability before lif-
ting the unit to the mounting location.
7. For horizontal displacement, use
rollers of equal diameter under the
wooden base.
Fig. 01 - Transport and Handling Instructions.
TRANSPORT
WARNING!
!
Each of the cables, chains or slings
used to lift the unit must be capable
of supporting the entire weight of
the unit.
WARNING!
!
The lifting equipment capacity
must exceed the unit weight by
a proper safety factor in order to
avoid death or equipment damage.

Installation Checklist
Complete this checklist after ins-
talling the unit to verify that all re-
commended installation procedures
are complete before start-up.
This checklist does not replace the
detailed instructions in the appro-
priate sections of this manual. Alwa-
ys read the entire section carefully
to become familiar with the procedu-
res.
Receiving
The unit and parts have been
inspected to check for shipping
damages.
The unit has been checked for
missing controls and materials.
The nameplate data matches the
order data.
Unit Location
The unit package has been re-
moved from the unit. Do not re-
move the skid until the unit is at
its nal location.
The unit location is appropriate
for the size of the unit and all air
ducts, refrigeration pipings and
electrical ducts.
There are proper access and
maintenance clearances provi-
ded around the unit.
Unit Handling
Proceed according to instruc-
tions on of this manual.
Unit Installation
The unit is located at its nal po-
sition.
The skid and screws have been
removed.
The unit is properly installed and
the drain slope is correct.
Rubber pads or isolators are
properly adjusted (if installed).
Compressor pad screws have
been re-tightened.
Component Review
Fan and motor shafts are paral-
lel.
Fan and motor sheaves are alig-
ned.
The fan belt tension is correct.
Rotors can be freely turned.
Locking screws, bearing screws
and sheaves are tightened.
Bearings do not oscillate when
turned.
Air Ducts
The unit return duct (if used) is
secured and at least 8 cm of e-
xible duct or canvas are availab-
le.
The air supply duct must not be
changed or reduced, and its di-
rection must not be altered. The
distance to the air supply dis-
charge should be at least three
times the duct diameter. Place
at least 8 cm of exible duct or
canvas.

perly installed in an area away
from lamp heat, warm or cold
air ows, direct sun light and not
behind any doors.
Wiring Diagrams
Check the wiring diagram on the
internal cover of the electrical
panel.
Power is supplied to the AC unit
by disconnecting switches or cir-
cuit breakers.
Verify that all electrical terminals
are re-tighten.
Check phase sequencing and
unit connections.

zes recommended for the intercon-
nection.
The equivalent lengths indicated al-
ready include losses due to valves,
curves, elbows, reductions, etc.
