Installation 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

Installation 2.4.2 Removal of Skid • Remove the plywood skirting that keeps the skid and unit in place. • Raise the Challenger 3000 off the skid. Liebert recommends using a fork lift (see Figure 1) or similar machine to ensure that the unit is lifted properly. • Once the unit is raised, the skid can be removed.

Installation 2.5 Piping Considerations All piping below the elevated floor must be located so that it offers the least resistance to air flow. Careful planning of the piping layout under the raised floor is required to prevent the air flow from being blocked. When installing piping on the subfloor, it is recommended that the pipes be mounted in a horizontal plane rather than stacked one above the other. Whenever possible, the pipes should be run parallel to the air flow. Condensate pumps for

Installation 2.7.2 Ducted Applications For ducted applications on units, the duct work may be attached to the top perimeter of the unit. Refer to Figure 2 for information on upflow units and to Figure 3 for downflow units. The duct work on upflow units must allow access to the motors/blowers for maintenance. The duct work on upflow units must be designed within the capacity of the unit, otherwise air flow and perfor- mance will be compromised. 2.7.3 Plenum Installation A solid plenum or plenum
