The rear drain can be used with wall thickness of up to
10 inches where a water trap can be installed between
the unit and the interior wall. See Figure 8B. 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 8C.
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 reinstalled.
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.
