Site Preparation and Installation

5.0SITE PREPARATION AND INSTALLATION

NOTE

Before installing unit, determine whether any building alterations are required to run piping, wiring and duct work. Carefully follow all unit dimensional drawings and refer to the submittal engineering dimensional drawings of individual units for proper clearances.

5.1Installation Considerations

The evaporator unit is usually mounted above the suspended ceiling in the space to be conditioned. Ducted systems may be located in a different room. Refer to Figure 8 and Figure 9 for possible configurations. The condensing unit may be:

•Indoor Air-Cooled Centrifugal Fan Condensing Unit mounted remotely or close coupled to the evaporator in the ceiling space.

•Outdoor Air-Cooled Propeller Fan Condensing Unit.

•Water/Glycol Cooled Condensing Unit, mounted remotely or close coupled to the evaporator.

5.1.1Room Preparation

The room should be well insulated and must have a sealed vapor barrier. The vapor barrier in the ceiling and walls can be a polyethylene film. Paint on concrete walls and floors should contain either rubber or plastic.

NOTE

The single most important requirement for maintaining environmental control in the conditioned room is the vapor barrier.

Outside or fresh air should be kept to a minimum when tight temperature and humidity control is required. Outside air adds to the cooling, heating, dehumidifying and humidifying loads of the site. Doors should be properly sealed to minimize leaks and should not contain ventilation grilles.
