Trane Fan-coil FCKB

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.

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.

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.

Sign off on the motor replacement

Change or clean air filters at least twice a year. Filters require more frequent care under high load or dirty air conditions since a clogged filter reduces airflow.

Throwaway and pleated media filters are available for all units.

All models except vertical cabinets

Remove the front panel of the vertical recessed unit and open the bottom panel door of the horizontal cabinet and horizontal recessed unit to access the filter. The front panel of the vertical cabinet unit does not require removal to change the filter.

Note: Vertical recessed, horizontal cabinet, & horizontal recessed units with a bottom return have filter guides to secure the filter in position. Also, if these unit types have a fresh air opening, they require an additional filter for the fresh air opening.

Replace all panels and filters properly!

All unit panels and filters must be in place prior to unit startup. Failure to have panels and filters in place may result in equipment damage.

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.
