Rigging

To ensure safe installation of the unit when a ceiling mount application is specified, estimate the
unit's approximate center of gravity. The configuration of internal components for each unit is
different and the weight is unevenly distributed.
Determine the actual center of gravity of the unit by performing a test lift. Lifting an unbalanced unit
can cause personal injury, or even death.

Installation site

Lock all electrical power supply switches in the OFF position before installing the unit. Failure to
disconnect the power supply may result in electrical shock or even death.

Location

To ensure the unit operates at maximum efficiencies, choose a dry indoor area where the
temperature is controlled between 50.0°F and 115.0°F. When choosing a location to install the
unit, consider the surrounding area. Occupants may object to common vibration and sound levels
associated with the unit.
Failure to allow adequate space between units, condenser intake and discharge may result in poor unit
performance and possible unit failure.
Install thermostats, air supplies, and returns so that each unit operates only on an individual unit
control. To assure fast drainage of the condensate run-off, the unit can be slightly pitched in the
same direction as the drain pan outlet.

Cabinet configuration options

Horizontal units have two parts: an evaporator and a condenser section. To minimize installation
costs and delays on site, it is recommended to order the units in the appropriate configuration.
Units 2–8 tons can be ordered from the factory as either packaged or split. The 10 ton unit only
comes factory-split.
Here are examples of cabinet configurations. See
