Installation considerations

WARNING

Hazardous Voltage w/Capacitors! Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/ tagout procedures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided by Trane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

Receiving and Handling

Upon delivery, inspect all components for possible shipping damage. See the Receiving Checklist section for detailed instructions. Trane recommends leaving units and accessories in their shipping packages/skids for protection and ease of handling until installation.

Shipping Package

UniTrane fan-coil and Force Flo cabinet heaters ship in individual cartons for handling and storage ease. Each carton has tagging information such as the model number, sales order number, serial number, unit size, piping connections, and unit style to help properly locate the unit in the floor plan. If specified, the unit will ship with tagging designated by the customer.

Receiving Checklist

Complete the following checklist immediately after receiving unit shipment to detect possible shipping damage.

!Inspect individual cartons before accepting. Check for rattles, bent carton corners, or other visible indications of shipping damage.

!If a unit appears damaged, inspect it immediately before accepting the shipment. Manually rotate the fan wheel to ensure it turns freely. Make specific notations concerning the damage on the freight bill. Do not refuse delivery.

!Inspect the unit for concealed damage before it is stored and as soon as possible after delivery. Report concealed damage to the freight line within the allotted time after delivery. Check with the carrier for their allotted time to submit a claim.

!Do not move damaged material from the receiving location. It is the receiver’s responsibility to provide reasonable evidence that concealed damage did not occur after delivery.

!Do not continue unpacking the shipment if it appears damaged. Retain all internal packing, cartons, and crate. Take photos of damaged material.

!Notify the carrier’s terminal of the damage immediately by phone and mail. Request an immediate joint inspection of the damage by the carrier and consignee.

!Notify your Trane representative of the damage and arrange for repair. Have the carrier inspect the damage before making any repairs to the unit.

!Compare the electrical data on the unit nameplate with the ordering and shipping information to verify the correct unit is received.

Jobsite Storage

This unit is intended for indoor use only. Store the unit indoors to protect the unit from damage due to the elements. If indoor storage is not possible, make the following provisions for outdoor storage:

1.Place the unit(s) on a dry surface or raised off the ground to assure adequate air circulation beneath unit and to assure that no portion of the unit contacts standing water at any time.

2.Cover the entire unit with a canvas tarp only. Do not use clear, black or plastic tarps as they may cause excessive moisture condensation and equipment damage.

Installation Preparation

Before installing the unit, consider the following unit location recommendations to ensure proper unit operation.

1.Clearances: Allow adequate service and code clearances as recommended in “Service Access” section. Position the unit and skid assembly in its final location.

2.Structural support: Ensure the structural support is strong enough to adequately support the unit. The installer is responsible for supply support rods for installation of ceiling units.

3.Level: Verify the floor or foundation is level. Shim or repair as necessary. To ensure proper unit operation, install the unit level (zero tolerance) in both horizontal axes. Failure to level the unit properly can result in condensate management problems, such as standing water inside the unit.

4.Condensate line & piping: Consider coil piping and condensate drain requirements. Verify condensate line is continuously pitched 1 inch per 10 feet of condensate line run to adequately drain condensate.

5.Wall & ceiling openings: Vertical recessed/concealed units require wall/ ceiling openings. Refer to submittal for specific dimensions before attempting to install. Horizontal recessed/concealed units must meet the requirements of the National Fire Protection Association (NFPA) Standard 90A or 90B concerning the use of concealed ceiling spaces as return air plenums. Refer to the submittal for specific dimensions of ceiling openings.

6.Exterior: Touch up painted panels if necessary. If panels need paint, sanding is not necessary. However, clean the surface of any oil, grease, or dirt residue so the paint will adhere. Purchase factory approved touch up epoxy paint from your local Trane Service Parts Center and apply.
