Pre-Startup Checklist

Complete this checklist after installing the unit to verify all recommended installation procedures are complete before unit startup. This does not replace the detailed instructions in the appropriate sections of this manual. Disconnect electrical power before performing this checklist. Always read the entire section carefully to become familiar with the procedures.

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

!Inspect unit and components for shipping damage. File damage claims immediately with the delivering carrier.

!Check unit for missing material. Look for ship-with options and sensors that may be packaged separately from the main unit. See the “Receiving and Handling” section.

!Check nameplate unit data so that it matches the sales order requirements.

Unit Location

1.Ensure the unit location is adequate for unit dimensions, ductwork, piping, and electrical connections.

2.Ensure access and maintenance clearances around the unit are adequate.

Unit Mounting

1. Ensure unit is installed level.

Component Overview

1.Ensure the fan rotates freely in the correct direction.

2.Ensure all unit access panels and air grilles are in place.

3.Verify that a clean air filter is in place.

4.Properly set the damper position to meet the fresh air requirement.

Unit Piping

1.Properly vent the hydronic coil to allow water flow through the unit.

2.Units with deluxe piping package: Tighten unions adequately.

3.Set water flow to the unit properly if unit piping has the circuit setter valve.

4.Check strainers (if supplied) for debris after apply system water.

5.Install the auxiliary drain pan and route the main drain pan hoses to the auxiliary drain pan on vertical fan-coil units.

6.Verify the condensate drain piping is complete for the unit drain pan.

7.Ensure the drain pan and condensate line are not obstructed. Remove any foreign matter that may have fallen into the drain pan during installation.

Electrical

#Check all electrical connections for tightness.

Note: Some circumstances may require the unit to run before building construc- tion is complete. These operating conditions may be beyond the design parameters of the unit and may ad- versely affect the unit.
