NOTE

Before installing unit, determine whether any building alterations are required to run piping,

wiring and ductwork. Follow all unit dimensional drawings and refer to the submittal

engineering dimensional drawings of individual units for proper clearances.

Installation 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 Figures 8- 10 for possible configurations.

The system may be:

• Self-contained air-cooled with centrifugal condenser fan attached to the evaporator box.

• Split system air-cooled with outdoor propeller fan condensing units.

• Self-contained chiller water, requiring connection to building chilled water loop.

• Self-contained water/glycol-cooled, requiring water or glycol loop connection.

Room 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 vapor barrier is the single most important requirement for maintaining environmental

control in the conditioned area.

Outside or fresh air should be kept to a minimum when tight temperature and humidity control is

required. Outside air adds to the site's cooling, heating, dehumidifying and humidifying loads. Doors

should be properly sealed to minimize leaks and should not contain ventilation grilles.

NOTE

Temperature and humidity sensors are located in the wall box. Proper and efficient cooling

requires placing the wall box where discharge air does not directly blow on the sensors.
