Locating the Unit
Verify that the floor is level, solid and appropriate construction to support the unit. When installing the
unit, enough space must be allowed for airflow clearance, wiring, plumbing and service access. It is
recommended that each side and front have a clearance of at least 36” (914mm) to allow the doors to
swing open and for servicing the unit.
The doors on some sides may not require as much service clearance. Refer to the specific unit
component breakdown drawings for assistance. Rear clearance is not required, but 1” to 2” (25 to
50mm) of clearance is suggested.
For the best air distribution, the unit should be centered against the longest wall, distributing the cold
air as close to heat load as possible, unless the unit is ducted. The unit should not be placed near any
corner of the room or at the end of a long, narrow room. Install the units as close as possible to the
largest heat load. Multiple units should be evenly spaced, as far apart as possible. It is recommended
to install an under-floor water detection system.
NOTE: Condensation formation and frequent humidifier flushing are
normal functions of this equipment. Proper drain connections must be
made to ensure proper removal. Unit will require water connections for
condensate removal and possibly for humidifier makeup water, chilled
water and/or hot water. Installation of units above equipment that could
sustain water damage should be avoided
Downflow Units
Downflow units will typically sit on an elevated flooring system known as a raised floor. The unit dis-
charges air downward which pressurizes the raised floor and channels upward through perforated floor
tiles. Location and quantity of perforated tiles will dictate proper air distribution. If the raised floor is
strong enough to support the unit and local codes permit, the unit can be placed directly on top with
cutouts made for the discharge openings.
Verify that the raised floor has been properly sized for the unit’s airflow and the room is free of airflow
restrictions. Perforated floor tiles in the raised floor should ensure minimal pressure loss. The raised
floor must provide a minimum of 12” (305 mm) clearance. Ensure that there is adequate clearance
above the unit for service, such as replacing filters. Optional plenums are available for downflow unit
ducting.
