Application of this product should be
within the cataloged airflow and cooling
considerations.
Low Ambient Cooling
This Voyager line features, as standard,
low ambient cooling down to 0°F. Contact
your local Trane Representative for more
assistance with low ambient cooling
applications.
Barometric Relief
This product line offers an optional
barometric relief damper included in the
downflow economizer accessory. 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.
PRESSURE DROP OF THE RETURN AIR
SYSTEM SHOULD BE CONSIDERED TO
CONTROL BUILDING PRESSURIZATION.
Power Exhaust Accessory
The power exhaust accessory is
available on all downflow units. This
accessory can be field installed and will
assist in relieving building pressurization.
Condensate Trap
The evaporator is a draw-thru
configuration. A trap must be field
provided prior to start-up on the cooling
cycle.
Clearance Requirements
The recommended clearances identified
with unit dimensions should be
maintained to assure adequate
serviceability, maximum capacity and
peak operating efficiency. Actual
clearances which appear inadequate
should be reviewed with the local Trane
sales personnel.
Unit Pitch
These units have sloped condensate
drain pans. Units must be installed level,
any unit slope must be toward access
side of unit.
