Checklists

Monthly Checklist

The following check list provides the recommended maintenance schedule to keep the unit running efficiently.

WARNING

Live Electrical Components! During installation, testing, servicing, and troubleshooting this equipment, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who is properly trained in handling live electrical components perform these tasks. Failure to follow all electrical components could result in death or serious injury.

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.

Monthly Maintenance

1.Inspect unit air filters. Clean or replace if airflow is blocked or if filters are dirty.

2.Check the main and auxiliary drain pans on fan-coil units to be

sure the pans are clean and do not impede the condensate flow through the drain line.

Annual Maintenance

Check and tighten all set screws, bolts, locking collars and sheaves.

1.Inspect the unit cabinetry for chips or corrosion. Clean or repair to provide unit protection.

2.Inspect the fan wheel and housing for damage. Rotate the fan

wheel manually to be sure movement is not blocked by obstructions.

3.Inspect the coil fins for excessive dirt or damage. Remove dirt and straighten fins.

4.Clean and tighten all electrical connections.

5.Inspect the strainer option for debris trapped in the filter screen.
