Pre-installation Checklist Jobsite Inspection Always perform the following checks before accepting a unit: 1. Verify that the nameplate data matches the data on the sales order and bill of lading (including electrical data). 2. Verify that the power supply complies with the unit nameplate specifications. 3. Visually inspect the exterior of the unit, for signs of shipping damage. Do not sign the bill of lading accepting the unit(s) until inspection has been completed.
General Information Unit Nameplate The unit nameplate is located in the left hand end pocket, behind the control box. It includes the unit model number, serial number, electrical characteristics, and other pertinent unit data. nance (oiling is not needed), and/or bearing replacement. Factory Shipment Before shipment, each unit is leak tested, and run tested for proper control operation.
General Information OA/RA Actuator (Option) The OA/RA actuator provides true spring return operation for positive close-off of the OA/RA damper. The spring return system of the actuator closes the outside damper if power is lost to the building. When ordered with factory controls, the actuator is a 3-point floating design. A 2 to 10 VDC actuator is available when other than Trane controls are specified. See Table 1 for OA/RA technical data.
Dimensions/Weights/ Clearance ! WARNING Improper Unit Lift! Test lift unit approximately 24 inches to verify proper center of gravity lift point. To avoid dropping of unit, reposition lifting point if unit is not level. Failure to properly lift unit could result in death or serious injury or possible equipment or property-only damage.

Installation Wall Box Installation The following instructions are general recommendations for installing wall intake boxes. Consult the architectural plans for specific requirements. Additional materials required to complete any specific installations (such as duct connections, metal mounting plates, or flanges) are not furnished by Trane. For best results, all air intake boxes should be removable from outside of the building. Weep holes must be at the bottom to permit free drainage.
Installation General Installation Checks The checklist below is a summary of the steps required to successfully install a unit. This checklist is intended to acquaint the installing personnel with procedures required in the installation process. It does not replace the detailed instructions called out in the applicable sections of this manual. 1 Carefully remove the stretch wrap and top cardboard cover.

Installation Unit Mounting Note: All wall intake boxes should be installed prior to mounting the unit ventilator. Refer to Page 14 for wall box installation instructions. The 1/2” mounting or anchoring holes are located on the back of the unit on each end. See Figure 3. 1 2 Note: All mounting fasteners are to be provided by the installer. Check the gasket on the rear of the unit and around the fresh air opening. Gaps around the openings can lead to outside air leaks into the room.
Installation Piping Installation Before installation of piping package, the shipping bracket holding the piping in place, must be removed. Proper installation of piping is necessary to provide efficient coil operation and to prevent damage during operation. Follow standard piping practices and include all accessories as necessary. Piping connection knockouts are shown pages 8 to 10. Field connection types and sizes for unit coils are listed in Table 5. These sizes are provided for field piping connection.
Installation Split System Units The following refrigerant piping and interconnecting wiring instructions apply to unit ventilators with direct expansion type cooling coils used in conjunction with air-cooled condensing units. Reference must also be made to the condensing unit installation and wiring manuals which are shipped with the condensing unit. Note: The ETL listing mark applied to a unit ventilator does not apply to any associated refrigerant condensing unit.
Installation Modulating Water Valves (Option) The actuator on the valve is a 24V, 3point floating valve. The actuator can be easily removed from the valve body by pressing in on the locking tab and rotating the actuator 45° counterclockwise (See Figure 6a). The 2-way valves are bi-directional flow. The 3way valves can be mixing or diverting (See Figure 6b). Note: The actuator must be removed if soldering is being conducted near the valve. High heat may cause damage to the actuator’s plastic body/mechanisms.
Installation Manually Opening Valve The manual opener can be manipulated only when in the up position. The A port can be manually opened by firmly pushing the white manual lever down to the midway position and pushing the lever in. In this position, both A and B ports are open. This “manual open” position may be used for filling, venting and draining the system or opening the valve during power failure.
Installation Soldering procedures are as follows: 1 Remove actuator as stated earlier. Wiring All classroom unit ventilators have 115V motor power. Motor data can be found in Tables G1. 2 Control Power 3 Place valves on the pipe. Rotate valve stem so the shaft slot points at the notch in the side of the body (90° to flow direction). This protects the plug inside the valve by removing it from the seat, Figure 14. Sweat the joints, keeping outer surface free from solder.
Installation ! WARNING Hazardous Voltage! Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.
