stems can be attached. This allows easy movement down halls, into elevators and
through doorways. If clearance is a problem the casters may be inserted directly into

Locating the Unit

2.5
Verify that the floor is level, solid and sufficient to support the unit. When installing the
unit, sufficient 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
particular 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:
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.

2.5.1 Downflow Units

Downflow units will typically sit on an elevated flooring system known as a raised floor.
The unit discharges 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
