Warranty
1.
The maximum allowable pressures for system leak
testing on low and high pressure side are given in
the chapter “Installation”. Insure to do not exceed
test pressure by using appropriate device.
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.
2.
Disconnect the main power supply before any
servicing on the unit.
Refrigerant
3.
Service work on the refrigeration system and the
electrical system should be carried out only by
qualified and experienced personnel.
4.
To avoid any risk, it is recommended to place the
unit on an area with restricted access.
Safety Recommendations
To avoid death, injury, equipment or property damage,
the following recommendations should be observed
during maintenance and service visits:
4
Consult the addendum to Manuals for units with
refrigerant, for conformity to the Pressure Equipment
Directive (PED) 97/23/EC and Machinery Directive
2006/42/EC.
RT-SVX056D-GB
General information
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:
a.
The unit is stored before it is installed; or,
b.
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, Supply Air and Return Air
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”.
• U
nits charged with refrigerant should not be stored
where temperatures exceed 68°C.
• A
t least every three months, attach a gauge and
manually check the pressure in the refrigerant circuit.
• If the refrigerant pressure is below 13 bar at 20°C
(or 10 bar at 10°C), call a qualified service organization
or Trane Sales Office.
The Trane Company will not assume responsibility for
equipment damage resulting from accumulation of
condensate on the unit electrical components.
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.

Unit Operating Principle
This section describes the overall flow chart principle for Airfinity. Detailed information for a given order is supplied
with order package documentation.

RT-SVX056D-GB
Installation
General information: The installation must conform to
all local standards and regulations.
Reception of Units
Unit Handling
The unit is supplied on wooden blocks. It is
recommended to check the machine’s condition upon
reception.
There are two ways to handle the unit:
1. Handle the machine using a forklift, in accordance
with applicable safety regulations. Handling of the
unit is prohibited unless forks are longer than the
length of the unit (not recommended as there is a
risk of damage if not done carefully).
2. Use a lifting beam correctly adjusted to fit the unit
(recommended).
Roof Curb Installation
Roof curbs are available as an accessory for “downflow”
units to support the unit and ensure the water tightness
between the rooftop and the roof. Four types of
roofcurbs are available: the standard version to allow the
installation of the unit on a flat roof with different return
flow patterns (return roofcurb down, return roofcurb
horizontal, multidirectional roofcurb) and the adjustable
version for a slope roof installation (adjustable roofcurb
down). The roofcurb characteristic is given in roofcurb
submittal drawings sent with the unit.
Figure 2 - Roofcurb down
The units are supplied on the truck but are not
unloaded. A lifting lug is provided on each corner of the
unit’s base to facilitate handling. 4 shackles and 4 slings
are required.
Use a lifting beam to prevent the cables pressing too
hard on top of the unit during lifting.
Important: For unit to fit on the roof curb the wooden
blocks must be removed.
Lifting and moving Instructions
Specific lifting method is recommended as follows:
1 - The units are supplied with four lifting points
2 - Slings and spreader bar to be provided by rigger and
attached to the four lifting points.
3 - Minimum rated lifting capacity (vertical) of each
sling and spreader bar shall be no less than the unit
shipping weight.
4 - Caution: The unit must be lifted with the utmost care.
Avoid shock load by lifting slowly and evenly.
5 - Remove slings and spreader bars when installation is
completed.
Figure 3 - Roofcurb multidirectional assembly
The detailed handling, lifting instructions including
all weights and sling lengths are given on the specific
drawings and instructions shipped with the unit.
RT-SVX056D-GB
19
Installation
Instructions for the roofcurb assembly and installation
with curb dimensions are provided with each roofcurb
kit.
In order to insure watertighness of the roofcurb
assembly, it is important to respect the schematics
below and to consult the booklet for roofcurb assembly
shipped with the roofcurb module. Be sure that gasket is
positioned on the roofcurb and without damage before
unit positioning.
To avoid any property damage or personal injury, it
is the installer’s responsibility to make sure that the
installation will not impair the function of this curb, or
the unit to be installed; and that the roofcurb and unit
must be completely sealed, preventing any water or air
leakage damage.
Installing the Unit
The structure accommodating the unit(s) must be
designed to support the equipment in operation, as
a minimum. Refer to submittals drawings supplied
with the unit for dimensions, weight and clearance
requirement around unit.
Unit support
Install the unit on a flat foundation strong enough to
support unit loading and level (within 5 mm across
the length and width of the unit).If the unit is to be
roof mounted check the building codes for weight
distribution requirements
Location and clearances
Choose a location that will enable air to circulate
freely in the condenser coil and allow air to be
discharged above the fans. The clearance distances
for air circulation and maintenance are indicated in
the submittals drawings.
Figure 4 - Waterproofing
4
Placing and rigging
The rooftop units are designed to be installed outdoor
and must be positioned horizontally (vertical air
discharge off the condenser).
3
1
Slab mount
2
For ground level installation, the unit base should be
adequately supported and hold the unit near level.
In areas where snowfall is common, the unit must
be elevated enough to ensure that the bottom of the
outdoor coil is above the height of the expected snow
accumulation.

3.
4.
Roofcurb
Roof membrane
Seal
Rooftop
Where severely cold temperatures are a consideration,
elevation of the unit is again recommended to ensure
that defrost water does not create an ice build up that
will interfere with unit operation. In addition, runoff
water from roofs, etc... must not be allowed to fall on
the outdoor coil; any blockage of airflow through the
coil can be detrimental to unit operation and reliability.
The manufacturer suggests that the bottom of the
outdoor coil be raised 30cm above grade or roof to
prevent possible ice build-up problems.
The unit frame structure is not designed to be
supported by four points (mounting on spring isolators
for instance).
The unit must therefore rest on its whole base.

Installation
Dimensions/Weights and Clearance
Attaching horizontal ductwork to unit
This information is supplied in the document package
shipped with the unit.
-A
ll conditioned air ductwork should be insulated
to minimize heating and cooling duct losses. Use
minimum of 5cm of insulation with a vapor barrier.
The outside ductwork must be weather proofed
between the unit and the building.
Connection of Duct Network
Supply and return openings have curb flanges provided
for easy duct installation. It is recommended to insulate
the circumference of the curb after the unit is mounted
to prevent condensation.
CAUTION! All ductwork must be run and attached to the
curb flanges before the unit is set into place.
Guidelines for ductwork construction
- Connections to the unit should be made with 7.5cm
canvas connectors to minimize noise and vibration
transmission.
- Elbows with turning vanes or splitters recommended
to minimize air noise and resistance.
- The first elbow in the ductwork leaving the unit should
be no closer than 60cm from the unit, to minimize
noise and resistance.
Figure 7 - Supplied trap

hen attaching ductwork to a horizontal unit, provide
a flexible watertight connection to prevent noise
transmission from the unit to the ducts. The flexible
connection must be indoors and made out of heavy
canvas.
Note: Do not draw the canvas taut between the solid
ducts.
Condensate Drain Piping
Each unit is equipped with a diameter 35 mm male
drainage connector. A P trap is supplied and must be
connected to the drainage as shown in Figure 7.
Slope the drainage pipe down at least 1% to ensure an
adequate condensate flow.
Check all the condensate drainage pipe fittings comply
with the applicable construction regulations and waste
disposal standards.

Installation
Supply fan Airflow measurement option
The airflow measurement option when selected is
associated with an air differential pressure sensor which
measures the pressure difference before the inlet nozzle
and inside the inlet nozzle.
Unit air flow can be calculated on the basis of the
differential pressure (difference in pressure of the static
pressures) in keeping with the following equation:
Qv in [m3/h] and ∆p in [Pa]
N number of fans
k takes into account the specific nozzle characteristics.
Connection on the unit side is accomplished via a premounted T tube connector. This tube connector is suited
for pneumatic hoses with an internal diameter of 4 mm.
It is recommended to install one expansion valve as
close as possible to each installed unit. The piping must
be self-supporting before the final branch connection
to the unit. Allow for a dust trap (filter) upstream of the
connection to the unit. Search for gas pipe leaks using
tensio-active product such as “Teepol” or “1000 bulles”
or another equivalent method. Soapy water must not be
used.
WARNING!
Never use a flame to search for leaks. The required gas
pressures at the unit’s inlet connection are specified
in table «Marking Category of gas section in different
countries»
CAUTION!
The piping must not exert any stress on the branch
connection to the burner.
The heating system must be isolated by the gas stop
valve on the gas supply piping during the pressure tests,
as soon as the pressure exceeds 0.060 bar (60 mbar).
If pressure greater than 0.060 bar is applied to the gas
valve inlet the unit may be damaged. In this case it is
mandatory to add a pressure reducer.
Connect condensation pipe for modulating burner.
2 stages burner is not supposed produce condensate
and the small amount of condensate possibly produced
in particular working conditions will in case evaporate

Electrical Connections
The electric panel is located on the length of the indoor
section behind the plug fan section. The unit is designed
to run with 400V (+/-10%) - 50 Hz (+/-1%) - 3 ph.
2 glands are available on each unit to be able to connect
the unit to the main supply either from the side or from
the bottom.
CAUTION!
Be sure that layout of electrical conduit is remote
enough from hot components (burner, electrical
heater...).
26
Proper phasing of the electrical power wiring is
critical for proper operation and reliability of the scroll
compressor and fans.
Proper rotation of the scroll compressor must
be established before the unit is started. This is
accomplished by confirming that the electrical phase
sequence of the power supply is correct. The motor is
internally connected for clockwise rotation with the inlet
power supply phased A, B, C.
The direction of rotation may be reversed by
interchanging any two of the line wires. It is this
possible interchange of wiring that makes a phase
sequence indicator necessary if the operator is to
quickly determine the phase rotation of the compressor
motor.
The “ABC” indicator on the face of the phase indicator
will glow if phase is ABC for terminals L1, L2, and L3.
Oil Injection Valve: This is specific for Scroll compressor
with variable frequency drive (VFD).
Compressor drive:
In case of replacement, configuration will be done by
Trane service. There is no human interface and the
configuration is done via RS485 Modbus.
Drive cabinet is cooled by a fan on the bottom behind
the door. Air entering from the bottom through a grid
with filter and leaving from the top through a grid with
filter.
Filter maintenance: clean or change the drive filters if
necessary.

Building Pressurization Control
Barometric Relief
The barometric relief allows to minimize overpressure
in the building caused by the introduction of fresh air.
This option is typically installed when fresh air intake is
below 25% of the nominal air flow and when the return
air pressure drop is below 25Pa.
Barometric damper is available as option into
economizer option on downflow and not compatible
with heat recovery module unit only.
When the pressure of the building increase, the
dampers open and relieve air to the outside.
If the return air duct pressure drop is higher than the
building overpressure, the dampers will not open.
Fresh air hood installation
If the return air duct pressure drop is lower than the
building overpressure, the dampers will open and
relieve air outside of the building.

Exhaust Fans
The exhaust axial fans are used to minimize the
overpressure in the building caused by the introduction
of fresh air.
This option is typically used when the fresh air intake
needed is between 40 to 50% of the nominal air flow or
when the return air duct pressure drop is higher than
25Pa (<70Pa or 150Pa according to option selected).
This option includes hoods, gravity dampers and axial
fans.
Optional service Terminal allow to adjust exhaust fans
start and stop value according to fresh air damper
position.
When the supply air fan is ON, the exhaust fans turn on
whenever the position of the fresh air dampers meet or
exceed the exhaust fan set point. (If the potentiometer is
set at 40%, the exhaust fans will start when the fresh air
dampers will meet or exceed 40% opening).
Configured for Return roofcurb
(ESP=250 PA)
2 types of return roofcurbs modules have been
developped (downflow and horizontal flow) in order
to minimize overpressure in the buildng caused by
the introduction of fresh air when there is a significant
pressure drop in the return duct (250 Pa maximum) and
when supply fan is not enough to overcome both supply
and return external static pressure.
The module is fully controlled and powered by the
rooftop control. The assembly detail is given in the
submittal shipped with the document package sent
with the unit.
Figure 18 - Return roofcurb downflow
Operation
• When the exhaust fans are OFF :
- The barometric dampers open when the air pressure
inside the building increases.
As the building pressure increases, the pressure in
the unit return section also increases, opening the
dampers and relieving the air.
- If return air pressure drop>building overpressure
(∆P>Pb – Patm) → barometric damper is closed.
- If return air pressure drop<building overpressure
(∆P< Pb – Patm) → barometric damper opens and
a maximum of 25% of the nominal airflow can be
exhausted.
Figure 19 - Return roofcurb horizontal flow
• When the exhaust fans turn ON :
- Around 50% of airflow can be exhausted, depending
on the pressure drop in the return air duct.
- The two fans work always together, on stage ON-OFF.
- Each fan has two speeds, which makes 2 configurable
speeds by changing the wiring on site.
- The exhaust fan is started when fresh air dampers
meet or exceed a preset percentage of fresh air.

HWC applies when additional heat is required. Hot
water comes from external boiler or other device. HWC
provides heating with a coil located after the indoor coil
and offer full modulation heating control through the
use of a 3 ways valve. Control is based on mixed air
temperature and zone temperature.
Factory setting is given to heat pump operation. Hot
water is called in addition. Priority can be switched on
site.
Antifreeze protection opens the 3 ways valve when the
coil temperature is closed to the freezing point (2°C).
In antifreeze mode, unit operating, indoor fan is stopped
and unit locked out in manual reset. Fresh air damper
is closed and the modulating valves open. The freeze
protection works with manual reset.
Important notice: it is important that the pump
circulating hot water is permanently working to
avoid water to freeze in the coil. Otherwise, in order
to prevent water from freezing in the coil during
unoccupied period or shutdown limited period, it is
recommended to use ethylene glycol. The service of a
water treatment specialist is recommended as water
used can cause scaling deposits, erosion or corrosion.
Insulate and proceed to heater wire installation on
all the water piping likely to be exposed to freezing
temperatures in order to avoid freeze up of the coil
and heat losses. The water distribution network must
be fitted with vents in places where air is likely to
be trapped.

CO2 sensor
Clogged filter detector
CO2 sensor can be either in air return duct or wall
mounted. It maintains a CO2 concentration below a
preset value to ensure acceptable comfort.
This device is mounted in the filter section. The sensor
measures the difference in pressure before and after
the filter section. The information is sent to the optional
service terminal or the BMS.
Controls the opening of the fresh air damper of the
economizer. The outside air damper will modulate in
order to maintain the CO2 concentration below the
setpoint.
To open damper it should combine the amount of
desired fresh air and the free cooling mode to modulate
from 0 to 100% maximum opening of the dampers.
It is possible to preset a minimum opening during
commissioning.
The CO2 sensor is set for 0-10V analog outputs and
provide sensing of carbone dioxide over a range of
0-2000 ppm. The sensor requires a 24 VDC power
supply. Consult wiring diagram supplied with the unit
for details.
The resolution of analog outputs reaches 10 ppm CO2.
The information is then sent to the controller CH536 to
control the opening position of the fresh air damper.
Avoid locating the duct sensor on surfaces with an
uncooled, unheated area behind them or in “dead”
spot behind doors or in corners. The CO2 wall mounted
sensor should be placed on a flat surface, 1.4 m from
the floor in an area of the room where there is free air
circulation.

Economizer control
Opening Airflow Damper
Demand Control Ventilation
The mechanical opening of the damper is managed by
the actuator which is adjusted by Trane controller. In
Free cooling mode, fresh air flow can be adjusted thru
optional terminal but the maximum opening airflow
damper minimum position is set at 50% by default
and maximum factory setting is 95%. At installation,
Minimum Fresh Air Percentage during occupied time
have to be adjusted.
The 10 I/O for economizer allow 4 strategies for Demand
control ventilation
#1: Fixed Ventilation (design ventilation)
It is based on design occupancy of the zone.
Occupied standby setpoint = 0.6L/s per m2
(ASHRAE62.1) x Surface
Occupied setpoint = 4.72L/s per person
(ASHRAE62.1) x DesignOccupants# + Occupied
standby setpoint
#2: Occupancy-based ventilation – requires an
occupancy sensor
During occupied hours, depending on
occupancy sensor, we can switch between
2 setpoints
no people detected: Occupied Standby Setpoint
= 0.6L/s per m2 x Surface
people detected: Occupied Setpoint = 4.72L/s
per person x DesignOccupants# + Occupied
Standby Setpoint
#3: CO2-based ventilation – requires a space CO2 level
information (sensor or BAS)
Modulates between Occupied setpoint and Occupied
Standby setpoint with Damper control.
Emergency Ventilation override
Three possible external requests, with following priority
order
1. Pressurize
2. Purge
3. Exhaust
When those override modes are activated, heating or

Maintenance
End user Routine Maintenance
Some of the periodic maintenance functions for the
unit can be undertaken by the end user. This includes
replacing (disposable) or cleaning (permanent) air filters,
cleaning unit cabinet, cleaning the condenser coil, and
carrying out a general unit inspection on a regular basis.
WARNING! Disconnect the power supply before
removing access panels to service the unit. Failure to
disconnect power before attempting any servicing can
result in severe injury or death.
Air filters
It is very important for the central duct system air filters
and drive box filters to be kept clean.
These should be inspected at least once a month when
the system is in constant operation (in new buildings,
the filters should be checked every week for the first
four weeks). If disposable-type filters are used, they
should only be replaced with ones of the same type and
size.
The economizer fresh air filter should be inspected
(washed if needed) at least once a month.
Note: Do not attempt to clean disposable filters.
Permanent filters can be cleaned by washing with a
mild detergent and water. Ensure that the filters are
thoroughly dry before reinstalling them in the unit (or
duct system).
•
•
•
Unit duct connections, to ensure they are physically
sound and sealed to the unit casing
Unit mounting support, to ensure that it is sound
The unit, to ensure there is no obvious deterioration
Before the heating season, your service technician may
examine the following areas of your unit:
• The unit, to ensure that the condenser coil can
receive the required airflow (that the condenser fan
grille is not obstructed)
• The control panel wiring, to verify that all electrical
connections are tight, and that wire insulation is
intact
Troubleshooting Alarm and Warnings
The optional control display has the ability to provide
the service personnel with some unit diagnostics and
system status information.
1. Step the system through all of the available modes,
and verify operation of all outputs, controls, and
modes. If a problem in operation is noted in any
mode, proceed to troubleshooting search.
2. Refer to the individual component test procedures if
other microelectronic components are suspect.
3.In addition review carefully the components which
can lead to the alarm: temperature sensor, zone
temperature sensor, clogged filter switch
Note: Replace permanent filters when required or at
least annually if washing fails to clean them, or they
show signs of deterioration. Be sure to use the same
type and size as were originally installed.
Condenser coil
Unfiltered air circulates through the unit’s condenser
coil and can cause the coil’s surface to become clogged
with dust, dirt, etc. To clean the coil, brush the coil
surface in the direction of the fins with a soft bristled
brush.
Keep all vegetation away from the condenser coil area.
Hot water coil (option)
Stop the unit. Do not disconnect the main supply to the
unit. This will permit the anti-frost protection to continue
to operate, and avoid water to freeze-up in the coil.
Service Technician Maintenance
Before the cooling season, your service technician may
examine the following areas of your unit:
• Filters, for cleaning or replacement
• Motors and drives system components
• Economizer gaskets, for replacement if necessary
• Condenser coils, for cleaning
• Safety controls, for mechanical cleaning
• Electrical components and wiring, for replacement
and tightening of connections as necessary
• Condensate drain, for cleaning
