CAUTION! Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices or for equipment or property-damage-only accidents.
Safety Recommendations
To avoid death, injury, equipment or property damage, the following recommendations should be observed during maintenance and service visits:
1. The maximum allowable pressures for system leak testing on low and high pressure side are given in the chapter "Installation". Insure to do note exceed test pressure by using appropriate device.
2. Disconnect the main power supply before any servicing on the unit.
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.

Reception
On arrival, inspect the unit before signing the delivery note. Specify any visible damage on the delivery note, and send a registered letter of protest to the last carrier of the goods within 7 days of delivery.
Notify the localTRANE sales office at the same time.The delivery note must be clearly signed and countersigned by the driver.
Any concealed damage shall be notified by a registered letter of protest to the last carrier of the goods within 7 days of delivery. Notify the localTRANE sales office at the same time.
Important notice: No shipping claims will be accepted by TRANE if the above mentioned procedure is not respected. For more information, refer to the general sales conditions of your localTRANE sales office.
Note: Unit inspection in France. Delay to send registered letter in case of visible and concealed damage is only 72 hours.
Loose Parts Inventory
Check all the accessories and loose parts that are shipped with the unit against the shipping list. Included in these items will be the all kind of sensors, thermostat and electrical diagrams, service literature, which are placed inside the control panel and/or indoor section for shipment.
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
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-SVX056A-GB

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". · Units charged with refrigerant should not be stored
where temperatures exceed 68°C. · At 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 orTrane 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
Figure 1

RT-SVX056A-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).
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.
The detailled handling, lifting instructions including all weights and sling lengths are given on the specific drawings and instructions shipped with the unit.

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 submitalls drawings sent with the unit. Figure 2 - Roofcurb down
Figure 3 - Roofcurb multidirectionnal assembly

RT-SVX056A-GB

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 positionned on the roofcurb and without damage before unit positionning.
To avoid any property damage or personal injury, it is the installer's reponsibility 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 completly sealed, preventing any water or air leakage damage.
Figure 4 - Waterproofing

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, weigth 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.
Placing and rigging
The rooftop units are designed to be installed outdoor and must be positioned horizontally (vertical air discharge off the condenser).
Slab mount
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.
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
This information is supplied in the document package shipped with the unit.
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

Attaching horizontal ductwork to unit
- All 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.
- When 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 1 1/4" female drainage connector. A P trap is supplied and must be connected to the drainage as shown in Figure 5.
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 plug fan airflow adjustment
1) Order write up (OWU) indicate design airflow, supply and design air pressure drop.
2) Verify on site supply fan airflow. It should match OWU design airflow.
3) If on site airflow is different from OWU design airflow the actual supply and design air pressure drop should be different from design values, Trane service technician should be mandated to perform air flow adjustement and optimization.

According to the option chosen, airflow or fan RPM can be read directly on the optional display or should be determined by connecting a pressure drop meter to the pre mounted T connector.
Setup is -20%/+30% variation versus factory setting (190m3h-1/kW @ 250 Pa).

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 acomplished via a premounted T tube connector. This tube connector is suited for pneumatic hoses with an internal diameter of 4 mm.

Installation
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! After completion of wiring, check all electrical connections, and ensure all connections are tight. Replace and secure all electrical box covers and access doors before leaving unit or connecting power to circuit supplying unit.
Scroll compressors
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.

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 integrated as standard 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.
If the return air duct pressure drop is lower than the building overpressure, the dampers will open and relieve air outside of the building. Figure 12 - Barometric relief

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).
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.
· 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.

Figure 18

HWC applies when addtional heat is required. Hot water comes from external boiler or other device. HWC provides heating with a coil located after the indoir 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 services of a water treatment specialist are recommended if water used can cause scaling deposits or erosion. 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 maintenance
This CO2 sensor has excellent stability and requires no maintenance. In most environments the recommended calibration interval is five years. A trained service technician can use a portable CO2 meter to certify sensor calibration. If, when checking the sensor, the reading differs too much from the reference value, the sensor can be recalibrated in the field. A calibration kit, software, and calibration gases are required. If certified accuracy is required, the sensor must be calibrated against accurate and traceable calibration gases in a laboratory. Consult Trane BAS for further details.
Fire thermostat
U12 is the dedicated I/O. Optional fire thermostat should be configured if present according to wiring diagram.

CO2 sensor
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.
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.

Clogged filter detector
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.
Smoke Detector
This device is used to detect smoke in the air stream. It includes a factory mounted detector located in the control panel. When smoke is detected, it shuts off the unit.
Other accessories available
- DTS : duct mounted wired temperature sensor - TZS01 : wall mounted wired temperature sensor - THS04 : wall mounted thermostat Refer to separate documentation for more information.
Alarm and Warnings
Alarms stop the unit or reduce the heating/cooling capacity. Alarm can be either manual reset (requires human intervention to re-start the unit) or automatic reset. Warning run the unit in fall-back mode. Example : if outdoor air humidity sensor is not working, the economizer runs in dry-bulb mode. Events are accessible through optional local service terminal which display the current events and display history of past events (up to 99 alarms and 99 warnings).

Demand Control Ventilation
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.

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 minmum 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.

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 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).
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.
