Application Considerations

Application of this product should be
within the cataloged airflow and
cooling considerations.
Barometric Relief
This product line offers an optional
barometric relief damper for use in
conjunction with economizer option.
This accessory consists of gravity
dampers which open with increased
pressure. As the building air
pressure increases, the pressure in
the unit return air section also
increases, opening the dampers and
relieving the conditioned space.
Note: The effectiveness of
barometric relief damper
during economizing
operation is system related.
Note: Pressure drop of the return
air system should be
considered to control
building pressurization.
Black Epoxy Coil
The coils are manufactured with a
thermoset, vinyl coating that is
bonded to the aluminum fin stock
prior to the fin stamping process.
These coils are an economical option
for protection in mildly corrosive
environments.
Note: Not to be used where
seacoast applications exist.
Clearance Requirements
The recommended clearances
identified with unit dimensions
should be maintained to ensure
adequate serviceability, maximum
capacity and peak operating
efficiency. Actual clearances which
appear inadequate should be
reviewed with the local Trane sales
personnel.
Condensate Trap
The evaporator is a draw-thru
configuration. A trap must be field
provided prior to start-up on the
cooling cycle.
Heating Operation
The heat exchanger is manufactured
with aluminized steel. To prevent
condensation within the heat
exchanger, do not exceed 50%
outside air or a minimum mixed air
temperature of 40°F .
Optional Stainless Steel Heat
Exchanger
The optional stainless steel heat
exchanger is manufactured with 304
stainless steel. To prevent corrosion
and prolong heat exchanger
reliability, the minimum mixed air
temperature allowed across the heat
exchanger is 20°F .
The stainless steel heat exchanger
option is an excellent option that
compliments the dehumidification
package. Whenever high outside air
or outside applications exist, these
options should be utilized.
Low Ambient Cooling
The Voyager™ line features, with
ReliaTel™ microprocessor controls,
low ambient cooling down to 0°F .
The following options need to be
included/considered when low
ambient applications are required:
continuous fan operation, crankcase
heaters (standard), thermal
expansion valves, frostat.
Contact your local Trane
Representative for more assistance
with low ambient cooling
applications.
Unit Pitch
These units have sloped condensate
drain pans. Units must be installed
level. Any unit slope must be toward
access side of the unit.
