General information
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".
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.

Figure 5
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

Installation
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 of TKH, 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.

Installation
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 selfsupporting 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

Filter installation
To gain access to filters, remove the supply fan access panel on downflow units and the filter access panel on the end for horizontal units.
Each unit ships with 40 or 50 mm thick filters. Number and size of filters is determined by size and configuration of the unit.
CAUTION! Do not operate unit without filters in place.
The maximum pressure drops allowable on filters are:
EU2/G2: 120 Pa
EU4/G4: 150 Pa

Installation
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 the Tables 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 to Table 6.
