WARNING
Hazardous Service Procedures!
The maintenance and troubleshooting
procedures recommended in this sec-
tion of the manual could result in expo-
sure to electrical, mechanical or other
potential safety hazards. Always refer to
the safety warnings provided through-
out this manual concerning these pro-
cedures. When possible, disconnect all
electrical power including remote dis-
connects before servicing. Follow prop-
er 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 han-
dling live electrical components per-
form these tasks. Failure to follow all of
the recommended safety warnings pro-
vided, 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 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.
Figure 48:
For filter replacement, remove the screws
holding the front air grille and remove the grille.
Figure 49:
Slide out old filter and replace with new
filter. Reattach return air grille.
