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 below.
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.

Barometric Fresh Air Damper (Optional)

Before starting the removal 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 12 on page 16.
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 and the bottom 
can be pulled toward the front of the unit. 

Commercial Room Ventilator Option

Before starting the removal make sure the power has 
been turned off. The hinged return air grille 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.
