Maintenance
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 end pocket front panel.
2. Remove the return air grille by releasing the mounting
screws.
3. If there is no shelving or oth
er 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 UVs 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.
Filter Replacement. The air filter on the vertical unit is
located near the bottom of the unit. Filter sizing may be
found in Table 5, p. 11.
1. To remove the filters, take-off the air section’s front
panel.
2. Slide the filter out of the filter
rack on the bottom of the
unit.
3. Replace old filter with new
filter and re-attach front
panel.
Cleaning of the Drain Pan. The unit ventilators drain
pan is removable for periodic cleaning or easy access for
maintenance/drainage issues. Use Figure 60 and
Figure 61, p. 88, and the following steps for removing the
drain pan.
1. Turn off power to the unit and remove the front panel.
2. Disconnect the condensate drai
n line from the P-trap.
3. Disconnect fan plug.
4. Remove (4) pan clips located at each end of the pan’s
front
