Trane Fan-coil FC

Keep coils clean to maintain maximum performance. For operation at its highest efficiency, clean the coil often during periods of high demand or when dirty conditions prevail. Clean the coil a minimum of once a year to prevent dirt buildup in the coil fins, where it may not be visible.

Remove large debris from the coils and straighten fins before cleaning. Remove filters before cleaning.

Clean the coil fins using steam with detergent, hot water spray and detergent, or a commercially available chemical coil cleaner. Be sure to rinse coils thoroughly after cleaning.

Coil cleaning agents can be either acidic or highly alkaline. Handle chemical carefully. Proper handling should include goggles or face shield, chemical resistant gloves, boots, apron or suit as required.

For personal safety refer to the cleaning agent manufacturer’s Materials Safety Data Sheet and follow all recommended safe handling practices. Failure to follow all safety instructions could result in death or serious injury.

Inspecting and Cleaning Drain Pans

Clean the fan-coil unit’s main and auxiliary drain pans to ensure the unit drains condensate properly.

Check the condensate drain pan and drain line to assure the condensate drains properly at least every six months or as dictated by operating experience.

If evidence of standing water or condensate overflow exists, immediately identify and remedy the cause.

Clean the drain pans of any moisture or debris.

1. To remove the auxiliary drain pan, loosen the hose clamp (installer supplied) around the drain connection collar and disconnect the drain line.

2. Remove the overflow drain line to the auxiliary drain pan if it was installed.

3. Remove the condensate overflow switch option from the auxiliary drain pan.

The capacitor for all unit motors can be replaced should it fail. Contact the local Trane service department to replace the motor capacitor in the event it fails.

However, the motor itself cannot be repaired or rewound. If the motor fails, record the model number from the unit nameplate and present to the local Trane Service Parts Center to purchase a replacement. The motor bearings are permanently lubricated and do not require any further oiling.

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

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.

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.

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

Inspect the fan wheel and housing for damage. Rotate the fan wheel manually to be sure movement is not blocked by obstructions.

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

Clean and tighten all electrical connections.

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