Pre-Installation Requirements

Outdoor Storage Considerations

Outdoor storage is not recommended; however, when outdoor storage is necessary, several things

must be done to prevent damage:

Note: Keep the equipment in the original shipping container for protection and ease of handling.

• Select a well-drained area, preferably a concrete pad or blacktop surface.

• Place the unit on a dry surface or raised off the ground to ensure adequate air circulation

beneath the unit and to ensure no portion of the unit will contact standing water at any time.

• Loosen the belt tension on the drive belts.

• Cover the unit securely with a canvas tarp.

• Do not stack units.

• Do not pile other material on the unit.

Preparing the Unit Site

NOTICE

Microbial Growth!

The roof curb or foundation must be level and the condensate drain at the proper height for

proper coil drainage and condensate flow. Standing water and wet surfaces inside the

equipment can become an amplification site for microbial growth (mold), which may cause

odors and damage to the equipment and building materials.

NOTICE

Level Foundation!

A level foundation is critical to proper unit and door alignment, operation, and sealing. Failure to

level and align sections properly can lead to structural damage.

• Ensure the installation site can support the total weight of the unit. Refer to the unit submittals

for weights.

• Allow sufficient space for adequate free air and necessary service access. Refer to submittals

for specific minimums.

• Allow room for supply and return piping, ductwork, electrical connections, and coil removal.

• Ensure there is adequate height for condensate drain requirements. See “Drain Pan Trapping”

on page 54.

Note: If unit is installed in a mechanical room on a pad, inadequate height may necessitate core-

drilling the floor to attain proper trap height. Insufficient height could inhibit condensate

drainage and result in flooding the unit and/or equipment room.

• Confirm the roof curb or foundation of the mounting platform is level and large enough to

accommodate the unit. Refer to the unit submittals for specific dimensions.

• Provide adequate lighting for maintenance personnel to perform maintenance duties.

• Provide permanent power outlets in close proximity to the unit for installation and

maintenance.

• Depending upon job requirements, the customer may need to provide 120 Vac power to the unit

controller. Refer to submittals for more information. A dedicated 15-amp circuit is

recommended.
