2.0 INSTALLATION
2.1 Room Preparation
The room should be well insulated and must have a sealed vapor barrier. The vapor barrier in the
ceiling can be a polyethylene film type. Use a rubber or plastic base paint on concrete walls and floors.
Doors should not be undercut or have grilles in them.
Outside (or fresh) air should be kept to an absolute minimum. Outside air adds to the heating, cool-
ing, humidifying and dehumidifying loads of the site. It is recommended that outside air be kept
below 5% of the total air circulated in the room and be preconditioned.
2.2 Equipment Inspection
Upon arrival of the unit, inspect all items for visible and concealed damage. Damage should be imme-
diately reported to the carrier and a damage claim filed with a copy sent to Liebert or to your sales
representative.
2.3 Location Considerations
The unit can sit on top of an accessible elevated flooring system. It may be necessary to furnish addi-
tional pedestal support below the unit to ensure maximum structural support (see Table 1). A sepa-
rate floor stand for the unit may be used as support, independent of the elevated floor and installed
prior to the flooring system.
Provide approximately 34" (864 mm) service clearance on the front of the unit.
Avoid placing units in an alcove or at the extreme end of a room that has a high aspect ratio (long,
narrow room). Ducted units can be placed in room corners or ends as long as front access is main-
tained. Placing units too close together will reduce the effectiveness of the air distribution.
2.4 Equipment Handling
2.4.1 Handling With Skid
• Always keep the unit upright, indoors and protected from damage.
• If possible, transport the unit using a fork lift; otherwise, use a crane with belts or cables, avoid-
ing pressing on the top edges of the packaging.
• If using a fork lift, make sure the forks, if adjustable, are spread to the widest allowable distance
to still fit under the skid.
NOTE
GLYCOOL units require 34" (864 mm) service clearance on the right side of the unit in
addition to front service clearance.
NOTE
Locate and remove shipping screw on fan motor base.

WARNING
The instructions listed below are to be adhered to when handling this unit with or without the
skid. There is the potential for this unit to tip over if handled improperly, which will cause
damage to the unit and could cause injury or death to the unit handler(s).
!
CAUTION
While on the skid, the unit is too tall to fit through a standard height doorway (83 inches or
2108 mm tall). Any attempt to move the unit, while on the skid, through a standard doorway
will cause damage to the unit.
