MIST ELIMINATOR SERVICE
A mist eliminator is supplied with the wall sleeve. The
mist eliminator is constructed of an 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.
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
by using a vacuum cleaner. The outdoor grille must be
removed. Use the vacuum to remove dirt and debris
from the surface of the mist eliminator. If additional
cleaning is required, the mist eliminator will have to be
removed from the sleeve.
The ventilation package will have to be removed to
gain access tot he mist eliminator. If the blank off plate
option is used, it is not necessary to service the mist
eliminator. The steps necessary to remove each of the
vent options are listed on the following pages.
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.
