2.0 SITE PREPARATION AND INSTALLATION 2.1 Installation Considerations 4 Site Preparation and Installation The evaporator unit is usually mounted above the suspended ceiling using field supplied threaded rods. Refer to Figure 1 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. • Indoor Water/Glycol-Cooled Condensing Unit, mounted remotely or close coupled to the evaporator. 2.1.1 Room Preparation 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. Table 1 Application limits, evaporator and chilled-water units* Input Voltage Range of Return Air Conditions to Unit Min Max Dry Bulb Temp. Relative Humidity -5% +10% 65°F to 85°F (18°C to 29°C) 20% to 80% *Unit will operate at these conditions but will not control to these extremes.

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 be vapor resistant. 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.
2.1.2 Location Considerations ! 5 Site Preparation and Installation CAUTION Units contain water. Water leaks can cause damage to sensitive equipment below. DO NOT MOUNT UNITS OVER SENSITIVE EQUIPMENT. A field-supplied pan with drain must be installed beneath cooling units and water/glycol-cooled condensing unit. NOTE Do not mount units in areas where normal unit operating sound may disturb the working environment. Locate the evaporator unit over an unobstructed floor space if possible. This will allow easy access for routine maintenance or service. Do not attach additional devices to the exterior of the cabinet, as they could interfere with maintenance or service.
