ing these procedures. When possi-
ble, disconnect all electrical

tions apply to all types of unit ventila-

tained from the controls manufactur-
er.
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
content. Depending upon room condi-
tions, 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 re-
place as required.
Overloaded filters will reduce unit air
handling capacity, which may result in
insufficient heating during the morn-
ing warm-up period and loss of natural
cooling capacity during mild weather.
Filter Replacement
The air filter on the vertical unit is lo-
cated near the bottom of the unit Filter
sizing may be found on Table G1.
