Maintenance Procedures
Perform the following maintenance procedures to
ensure proper unit operation.
Live Electrical Components! During installation,
testing, servicing and troubleshooting of this product, it may
be necessary to work with live electrical components. Have a
qualified licensed electrician or other individual who has
been properly trained in handling live electrical components
perform these tasks. Failure to follow all electrical safety
precautions when exposed to live electrical components
could result in death or serious injury.
WARNING
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.
WARNING
Air Filters
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. Pleated
media filters are available for all units.
Depending on the Filter Removal Option installed in the
unit, filters can be removed from the unit in two ways:
1 - Side removal – from the either side of the coil
2 - Bottom removal – from the bottom of the coil side
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 could result in
equipment damage.
NOTICE
Inspecting and Cleaning Drain Pans
Clean the unit drain pan to ensure that any potential
condensate drains. 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.
Coil Maintenance
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.
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.
WARNING
Inspecting and Cleaning Coils
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. Follow the suggested methods in
the following paragraphs.
