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
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 re-installed.
Commercial Room Ventilator Option
Before starting the removal make sure the power has
been turned off. The hinged return air grille panel must
be opened. The commercial room ventilator (CRV) can
be seen after the panel has been removed. The CRV
must be removed to gain access to the mist eliminator.
1. The two mounting screws in the front of the CRV
must be removed.
2. The power connectors for the CRV (located on
the right side of the unit) must be disconnected.
Squeeze the tabs on the sides of the connector and
pull straight out. Unplug both of the connectors.
3. Slide the CRV straight out of the unit.
The mist eliminator can be seen through the opening
in the back of the unit. The mist eliminator must be
raised up and the bottom can be pulled toward the
front of the unit and removed.
