problem, the casters may be inserted directly into the bottom of the 1” tubular steel corner posts at

the bottom of the unit.

Warning: Improper lifting or moving of equipment may result in damage to decorative

doors, panels or frame members.

1.4 Locating the Unit

When installing the unit, sufﬁ cient space must be allowed for airﬂ ow clearance, wiring, plumbing and

service access. It is recommended that each side and front door have a clearance of at least 30” 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 inches of

clearance is suggested.

For best air distribution the unit should be centered against the longest wall, as close to the 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. Multiple units should be evenly spaced as far apart as possible.

NOTE TO INSTALLING CONTRACTOR: Condensation formation and frequent humidi-

ﬁ er ﬂ ushing are normal functions of this equipment. Proper drain connections must be

made to ensure proper removal. Unit will require water connections for condensation

removal and possibly for humidiﬁ er makeup water, condenser water and/or hot water.

Installation of units should be avoided above electronic equipment that sustain water

damage should be avoided at all times.

1.4.1 Downﬂ ow Units

Downﬂ ow units will typically sit on an elevated ﬂ ooring system commonly referred to as a raised

ﬂ oor. The unit discharges air downward which pressurizes the raised ﬂ oor area and channels air

upward through perforated ﬂ oor tiles. Location and quantity of perforated tiles will dictate proper

air distribution. If the raised ﬂ oor is strong enough to support the unit and local codes permit such

installations, the unit can be placed directly on top with cutouts made for discharge openings.

There may be additional support required in the form of adjustable (optional) jackstands. Jack-

stands are adjustable, threaded leveling rods which support the unit in each of the corners and in the

center on longer length units. Tighten the lock-nuts provided with each jackstand. The base plate

can rest on the ﬂ oor or on vibration isolation pads.

(Optional) ﬂ oorstands are also a way of supporting the unit. These are ordered to the height of the

ﬂ oor with leveling rods to allow adjustment. The ﬂ oorstand has lips at each corner to align the unit

which is place on top. It is recommended that the unit frame be bolted or screwed to the ﬂ oorstand

from below. Local codes may dictate this procedure. After installation, the raised ﬂ oor is typically

built around the unit.

The raised ﬂ oor serves as the distribution plenum for air on downﬂ ow units. Cables, pip-

ing, wiring raceways, inadequate ﬂ oor height (raised ﬂ oors less than 12 inches in height

are not recommended) and any other restrictions can inhibit proper air ﬂ ow. Care should

be taken to avoid any air restrictions.
