cedures. When possible, disconnect all

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 UV's
are specially designed for high lint con-
tent. Depending upon room conditions,
these filters will normally need to be
replaced every 4 to 8 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.
Filter Replacement
The air filter on the vertical unit is locat-
ed near the bottom of the unit (Figures
48 & 49).
1. To remove the filter, begin by
unscrewing the four screws holding
the unit's return air grille in place.
2. Remove air grille and slide the filter
out of the filter rack on the bottom of
the unit.
3. Replace old filter with new one and
re-attach return air grille
CAUTION
Equipment Damage
Do not operate unit without filters or
grille in place. Failure to do so may
cause equipment failure
For horizontal units, lower the back
access panel and lift the filter out of its
channel and out of the unit.
