Mist Eliminator Service; Figure 10C Rear Drain (Top View) - Bard QW2S3DA Installation Instructions Manual

The rear drain can be used with wall thickness of up
to 10" where a water trap can be installed between the
unit and the interior wall (see Figure 10B). The trap
cannot extend beyond the edge of the unit or it will
interfere with the wall mounting bracket. The drain can
be routed through the floor or through the wall. If the
drain is routed through the wall, the drain line must be
positioned such that it will not interfere with the sleeve
flange or the grille (see Figure 10C). If the drain is to
be routed through an unconditioned space, it must be
protected from freezing.

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
