FILTER
This unit must not be operated without a filter. It comes
equipped with a disposable filter which should be
checked often and replaced if dirty. Insufficient air flow
due to undersized duct systems or dirty filters can result
in nuisance tripping of the high or low pressure control.
Refer to Table 2 for correct air flow and static pressure
requirements. (See Figure 3.)
CONDENSATE DRAIN
Determine where the drain line will run. This drain line
contains cold water and must be insulated to avoid
droplets of water from condensing on the pipe and
dripping on finished floors or the ceiling under the unit.
A trap MUST BE installed in the drain line and the trap
filled with water prior to start up. The use of plugged
tees in place of elbows to facilitate cleaning is highly
recommended.
Drain lines must be installed according to local plumbing
codes. It is not recommended that any condensate drain
line be connected to a sewer main. The drain line enters
the unit through the FPT coupling on the coil side of the
unit.
PIPING ACCESS TO UNIT
Water piping to and from the unit enters the unit casing
from the coil side of the unit under the return air filter
rack. Piping connections are made directly to the unit
and are
3/4” FPT. (See Figure 4.)
