Pre-Installation
Installation Preparation
Before installing the unit, perform the following procedures to ensure proper unit operation.
1. Verify the floor or foundation is level. Shim or repair as necessary. To ensure proper unit
operation, install the unit level (zero tolerance) in both horizontal axes. Failure to level the unit
properly can result in condensate management problems, such as standing water inside the
unit. Standing water and wet surfaces inside units can result in microbial growth (mold) in the
drain pan that may cause unpleasant odors and serious health-related indoor air quality
problem.
2. Allow adequate service and code clearances as recommended in the “Service Access” section
(below). Position the unit and skid assembly in its final location. Test lift the unit to determine
exact unit balance and stability before hoisting it to the installation location.
Service Access
See Table 1, below, and Figure 2, p. 13 for recommended service and code clearances.
ƽ WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
