5.0 SITE PREPARATION AND INSTALLATION
5.1 Installation Considerations
The evaporator unit is usually mounted above the suspended ceiling of the space to be conditioned.
Ducted systems may be installed in a different room.
5.1.1 System Configurations
The typical system configuration has a separate evaporator or cooling unit and a condensing unit.
Chilled water systems are self-contained units. Refer to Tables 1 and 2 and to Figures 8, 9 and 10
for different system combinations and unit configurations that are possible.
NOTE
Before installing unit, determine whether any building alterations are required to run piping,
wiring and ductwork. Carefully follow all unit dimensional drawings and refer to the
submittal engineering dimensional drawings of individual units for proper clearances.

* Unit capacity ratings are stated for 95°F (35°C) for standard units and 105°F (41°C) for high ambient PFH units only.
Exceeding these rating points by 20°F (11°C) will result in lower cooling capacities, but will not damage the equipment.
