MIST ELIMINATOR SERVICE (Optional –
only used with one of the vent options)
A mist eliminator is supplied with the wall sleeve. The
mist eliminator is constructed of aluminum frame and
mesh. The mist eliminator is located in the top section
of the wall sleeve and can be removed from the inside of
the building without removing the unit from the wall.
This requires that the ventilation package must be
removed.
The steps necessary to remove each of the vent options
are listed following.
It is recommended that the mist eliminator be inspected
annually and serviced as required. The mist eliminator
can be inspected from the outside of the building by
looking through the outdoor grille. The mist eliminator
can be serviced from the outside. The outdoor grille
must be removed to do so.
The mist eliminator can be cleaned by washing
with soap and water. The excess water should
be shaken off the mist eliminator before it is
reinstalled.
BAROMETRIC FRESH AIR DAMPER

Before start to remove make sure the power has
been turned off. The hinged return air grille
panel must be opened. The fresh air damper
assembly can be seen on the back of the unit.
Refer to Figure 9.
1. The fresh air damper is attached to the back
of the unit with one screw on either side of
the assembly. Both of the screws must be
removed.
2. Once the mounting screws are removed, tilt
the assembly down and lift it out.
The mist eliminator can be seen through the
opening. The mist eliminator must be raised up
