2.0 INSTALLATION (APPLICABLE TO ALL MODELS)
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,
cooling, 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
immediately reported to the carrier and a damage claim filed with a copy sent to Emerson
®
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
additional pedestal support below the unit to ensure maximum structural support (see Table 1). A
separate 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" (864mm) 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
maintained. Placing units too close together will reduce the effectiveness of the air distribution.
2.4 Equipment Handling
NOTE
GLYCOOL units require 34" (864mm) 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.
