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,sufcientspacemustbeallowedforairowclearance,wiring,plumbingand
service access. It is recommended that each side and front have a clearance of at least 36” 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” of clear-
ance 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. Multiple units should be evenly
spaced, as far apart as possible.
Note to Installing Contractor:Condensationformationandfrequenthumidierush-
ing 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humidiermakeupwater,chilledwaterand/orhotwater.Installationof
units above equipment that could sustain water damage should be avoided.
1.4.1 Downow Units
Downowunitswilltypicallysitonanelevatedooringsystemknownasaraisedoor.Theunitdis-
chargesairdownwardwhichpressurizestheraisedoorandchannelsupwardthroughperforated
oortiles.Locationandquantityofperforatedtileswilldictateproperairdistribution.Iftheraised
oor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.
There may be additional support required in the form of adjustable jackstands. These are adjust-
able, threaded leveling rods which support the unit in each of the corners and in the center on longer
length units. Tighten the locknuts provided with each jackstand. The base plate can rest on the
oororonvibrationpads.
Floorstandsarealsoawayofsupportingtheunit.Theseareorderedtotheheightoftheoorwith
levelingrodstoallowadjustment.Theoorstandhaslipsineachcornertoalignwiththeunitwhich
isplacedontop.Itisrecommendedthattheunitframebeboltedorscrewedtotheoorstandfrom
below. Local building codes may dictate this procedure. After installation, the raised is typically built
around the unit.
Theraisedoorservesasthedistributionplenumforairondownowunits.Cables,pip-
ing,wiringraceways,inadequateoorheightandanyotherrestrictionscaninhibitproper
airow.Careshouldbetakentoavoidrestrictions.
