Cabinets will support a maximum weight of 400 lb when
installed beneath a vertical furnace or air-handling unit. When
setting furnace on cabinet, do not drop it into place. Position
furnace correctly on cabinet to prevent a corner from slipping
down and damaging cabinet.
Prior to installing this product:
1. Read rules and instructions carefully for safe operation.
Failure to follow them could damage product or cause
hazardous condition.
2. Check ratings given on product to make sure it is suitable for
your application.
Step 2—Details
1. Remove existing furnace filter and discard.
2. Air cleaner cannot remove existing dirt from blower and
ducts. Clean area thoroughly before you begin.
3. Install supplied foam tape on side of air cleaner casing that
comes in contact with the furnace.
4. Remove unit access panel, and slide prefilters and ionizing-
collecting cells out of cabinet. Place them safely aside with
warranty registration card. Remove any cardboard pieces
before proceeding.
NOTE:
The following is a typical installation of an air cleaner on
an upflow furnace. (See Fig. 8 and 11.) You may have to alter the
installation to fit your application.
5. Locate cabinet in cold air return duct so that all of return air
flows through unit. (See Fig. 8.) If furnace and air cleaner
openings are different, use a transition. (See Fig. 4.)
6. Mounting holes are provided for duct work attachment. (See
Fig. 8.) The 0.140-in. holes are sized for No. 8 sheet metal
screws, or 1/8-in. rivets. If adjoining ductwork is flanged,
install screws so that screw heads are inside cabinet. This will
prevent damage to prefilters and optional charcoal after-filter
during removal and installation after cleaning.
7. After unit has been secured, seal seams air tight with duct tape
or caulking.
In applications with minimum airflow, it is helpful to seal any
openings on power pack assembly or cabinet.
8. Refer to "Direction of Airflow."
9. Re-install power supply on top of cabinet.
10. Install prefilters and ionizer-collector cells.
11. Re-install cabinet front panel door assembly.
Step 3—Typical Mounting Positions
Air cleaner can be mounted in any position, except with the access
door facing down.
Seal all joints in return air system with duct tape between furnace
and air cleaner to prevent dust from entering clean airstream and to
assure proper operation of electronic airflow sensor.
Step 4—Electrical Installation
All wiring must comply with applicable local and national codes.
Be sure all incoming power is OFF before beginning any
procedures.
