Fig. 2 – Air Purifier Components

Identify Mounting Location

1. Identify a mounting orientation for the air purifier in the return air

duct (

Fig. 3

 and 

Fig. 4

).

IMPORTANT:  Ensure  airflow  direction  through  the  air  purifier

matches  the  arrows  on  the  face  of  the  air  purifier  cartridge  and

those on the label on the front of the cabinet. The air purifier can be

rotated 180° to accommodate the cabinet orientation

.

2. The location of the air purifier should be readily accessible. Enough

room should be provided for periodic replacement of the air purifier

cartridges.

Mount Cabinet

1. Turn off power to the heating and cooling system.
2. Remove the existing furnace filter and discard. Excessive system

static  may  result  if  the  air  purifier  is  used  with  other  filtration

devices. 

3. Remove the air purifier cartridge and Filter Enhancement Module

(FEM) from the air purifier cabinet (

Fig. 6

 and 

Fig. 7

).

4. If the air purifier is to be mounted in a side-flow application, affix

the adhesive-backed support foot to the side of the purifier that will

be on the floor, near the rear of the purifier, as shown in 

Fig. 8

.
