WARNING
Level Foundation!
The floor 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 air-handling units could result
in microbial growth, which may
cause unpleasant odors, serious
health problems, or death.
