WARNING
Hazardous Service Procedures!
The maintenance and troubleshooting procedures
recommended in this section of the manual could result
in exposure to electrical, mechanical or other potential
safety hazards. Always refer to the safety warnings
provided throughout this manual concerning these
procedures. When possible, disconnect all electrical
power including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized. When
necessary to work with live electrical components, have
a qualified licensed electrician or other individual who
has been trained in handling live electrical components
perform these tasks. Failure to follow all of the
recommended safety warnings provided, could result in
death or serious injury.
Service Access
To access the unit for water balancing, motor access or
other start-up and maintenance functions, use one of the
following methods:
1. Remove the entire front panel and put a blockoff over
the air chamber in the front.
2. Remove the return air grille by releasing the mounting
screws.
3. If there is no shelving or other obstructions, removing
the end panel may allow more access.
Periodic Maintenance
The following maintenance suggestions apply to all types
of unit ventilators, chilled water, hot water, split systems
and electric. Additional information for controls not
supplied by The Trane Company should be obtained from
the controls manufacturer.
Split system unit ventilators include a condensing unit and
the instructions provided with the condensing unit will
apply to the entire refrigerant system.
Filters
The air filters supplied with Trane unit ventilators are
specially designed for high lint content. Depending upon
room conditions, these filters will normally need to be
replaced every four to eight weeks. To assure proper unit
operation, inspect the filters monthly and clean or replace
as required.
Overloaded filters will reduce unit air handling capacity,
which may result in insufficient heating during the
morning warm-up period and loss of natural cooling
capacity during mild weather.
