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.

Important: Units must be installed level for proper drainage of condensate from the drain pan

and for squareness of the sections during installation. In addition, each section in a

multi-section unit must be properly supported.

Note: Leveling each section, beginning with the first section, is critical. Failure to level and align

the sections immediately creates greater misalignment or even structural damage

afterward.

1. The end section must be installed first making sure it’s properly aligned with the remainder of

the curb. Anchor this section securely so the base lugs can be used to pull the next section for

base connections.

2. For units with curb base, remove shipping blocks (see Figure 21).
