Warranty
Warranty is based on the general
terms and conditions of the
manufacturer.The warranty is void if
the equipment is repaired or
modified without the written
approval of the manufacturer, if the
operating limits are exceeded or if
the control system or the electrical
wiring is modified. Damage due to
misuse, lack of maintenance or
failure to comply with the
manufacturer's instructions or
recommendations is not covered by
the warranty obligation. If the user
does not conform to the rules of
this manual, it may entail
cancellation of warranty and
liabilities by the manufacturer.
Refrigerant
The refrigerant provided by the
manufacturer meets all the
requirements of our units. When
using recycled or reprocessed
refrigerant, it is advisable to ensure
its quality is equivalent to that of a
new refrigerant. For this, it is
necessary to have a precise analysis
made by a specialized laboratory. If
this condition is not respected, the
manufacturer warranty could be
cancelled.
Maintenance contract
It is strongly recommended that you
sign a maintenance contract with
your local Service Agency.This
contract provides regular
maintenance of your installation by
a specialist in our equipment.
Regular maintenance ensures that
any malfunction is detected and
corrected in good time and
minimizes the possibility that
serious damage will occur. Finally,
regular maintenance ensures the
maximum operating life of your
equipment. We would remind you
that failure to respect these
installation and maintenance
instructions may result in
immediate cancellation of the
warranty.
Storage
Take precautions to prevent
condensate formation inside the
unit's electrical components and
motors when:
1. The unit is stored before it is
installed; or,
2. The unit is set on the roof curb
and temporary auxiliary heat is
provided in the building.
Isolate all side panel service
entrances and base pan openings
(e.g., conduit holes, S/A and R/A
openings, and flue openings) to
minimize ambient air from entering
the unit until it is ready for start-up.
Do not use the unit's heater as
temporary heat without completing
the start-up procedures detailed
under "Unit Start-Up".
TheTrane Company will not assume
responsibility for equipment
damage resulting from
accumulation of condensate on the

Training
To assist you in obtaining the best
use of it and maintaining it in
perfect operating condition over a
long period of time, the
manufacturer has at your disposal a
refrigeration and air conditioning
service school. The principal aim of
this is to give operators and
technicians a better knowledge of
the equipment they are using, or
that is under their charge. Emphasis
is particularly given to the
importance of periodic checks on
the unit operating parameters as
well as on preventive maintenance,
which reduces the cost of owning
the unit by avoiding serious and
costly breakdown.

Installation
RT-SVX19A-E410
Installing the unit
1) Unit mounting on roof
Fix the rooftop curb on the joint
beam of the building's structure.
Make the rooftop curb's sealing
surface level using angle brackets
adjusted by screw bolts, located
around its perimeter. Place the
adhesive seals on the curb's sealing
surface (perimeter and cross
pieces). Make the rooftop leak-tight
around the curbs before installing
the unit, in compliance with current
construction standards.
Note:The unit must be installed
perfectly level to ensure
condensates flow from the
condensate tray.
The rooftop unit nests into the curb
and is supported by it. Position the
unit, taking care to comply with the
indicated directions: the unit's
discharge and intake openings must
match those of the curb.
2) Installing the unit on the ground
To install the unit on the ground, its
base must be level and supported
securely.
For horizontal discharge units, a
support is required such as a metal
or concrete slab whose height must
be determined according to the
amount of snow cover, to prevent
problems with condensation
drainage and obstruction of the
external coil. If necessary use an
anti-vibration material between the
rooftop unit's base and the support.
Note: Unit installation must comply
to local codes

Connection of duct
network
1) Downflow discharge units
(TKD,WKD,YKD)
Using the rooftop curb
• The rooftop curb must be
insulated on the outside walls at
the discharge and intake
openings to prevent
condensation in the ducts.
• The rims around the discharge
and intake openings make it
possible to attach the flanges on
the ends of the ducts. If you are
using rigid duct ends
recommended on the rooftop
curb plan, it is essential to fix
these components before
installing the unit.
• For the design of the duct
network, comply with
recommendations currently
applicable on the market, in
particular:
. Installation of a section of
flexible ducts to limit
transmission of the unit's
vibrations
. Use of movable vanes or
deflectors to reduce the sound
level.
2) Horizontal discharge units
(TKH,WKH,YKH)
• The intake and discharge ducts
must be insulated (thermal
insulation).
• The duct section located outside
must be leak-tight.
• Provide a flexible connector to
prevent transmission of the unit
vibrations.This flexible duct
must be installed inside the
building.
Note: In case of use ofTKH, WKH or
YKH units with economizer option,
temperature and humidity sensors
must be installed in return duct.
Economizer linkage is factory
mounted but the damper position
must be adjusted on site.

from the unit to avoid long, level,
horizontal runs. Refer to Figure 7.

Installation
13RT-SVX19A-E4
Gas pipework installation
The installation must conform to all
standards and regulations.
The gas supply pipework and gas
stop valve to be installed near the
unit must be sized so as to assure
the gas pressure is sufficient at the
unit inlet when operating at full
load.
CAUTION! Should the pressure at
the unit valve gas inlet be higher
than 0.035 bar, an expansion valve
must be installed.
The pipework must be self-
supporting and the final connection
to the burner must be made by a
flexible pipe. Provide a dust
protection (filter) upstream the unit
connection.
CAUTION!The gas pipework must
not exert any stress on the burner
gas connection.
Note: Expansion valve must be
adapted to the type of gas used:
• G 20 : 20 mb
• G 25 : 25 mb
• G 31 : (Propane): 37 or 50 mb
Table 4 - Gas burner models
SeeTable 38 for burner
performance.
Gas leak check procedure
1. Vent the gas line
2. Gas supply line pressure test:
close valve 4 and open valve 2
3. Leak-check the gas pipe
Look for gas pipe leaks using
"Typol", "1000 bulles" or a similar
product. Do not use soapy water.
WARNING! Never use an open
flame to check for gas leaks.
Required gas pressure at the unit
inlet connection are given in
Table 37.

Supply fan adjustment
Use the following procedure to
determine the proper adjustment of
the supply fan for a specific
application.
1. Determine total external static
pressure about system and
accessories.
a. Obtain the design airflow rate
and the design external static
pressure drop through the
distribution system.
b. Add static pressure drop of the
accessories installed on the
unit. (Table 7,8 & 9)
c. Add the total accessory static
pressure drop (from step 1b) to
the design external static
pressure (from step 1a).The
sum of these two values is the
total system external static
pressure.
2. Using theTables 10 through 20 to
find the external static pressure
that most closely approximates
total system external static
pressure.Then locate the
appropriate airflow rate for your
unit.The value obtained
represents the brake horsepower
for the supply fan motor and the
fan RPM.
3. Adjust motor sheave according
toTable 6.
