Trane Fan-coil FF

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.

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.

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.

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.

Keep coils clean to maintain maximum performance.

WARNING: Hazardous Chemicals! 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.

Coils become externally fouled as a result of normal operation. Dirt on the coil surface reduces it’s ability to transfer heat that can result in comfort problems, increased airflow resistance and thus increased operating energy costs.

If the coil surface dirt becomes wet, which commonly occurs with cooling coils, microbial growth (mold) may result, causing unpleasant odors and serious health-related indoor air quality problems.

Inspect coils at least every six months or more frequently as dictated by operating experience. Cleaning frequently is dependent upon system operating hours, filter maintenance, and efficiency and dirt load.

Steam and Hydronic Coil Cleaning Procedure

Disconnect all electrical power to the unit.
