PLANNING THE INSTALLATION

Application and Construction

The air cleaner should be installed in the occupied space return duct opening leading to a central air handling system. All of the air circulated by the system must pass through the electronic air cleaner.

The front door of the electronic air cleaner is hinged to provide access to the internal components. See Fig. 4.

The air cleaner has one or two electronic cell(s) that must be installed with the ionizer section (side with fine wires) facing the door.

The cell(s) is held in place by metal hooks and a quarter-turn latch.

A spring contact provides the electrical connection between the solid state power supply and the electronic cell(s). An interlock switch interrupts the line voltage to the power supply when the door is opened. A rocker-type ON-OFF switch allows the air cleaner to be turned off manually. An indicator light that is on shows that the air cleaner is energized and the power supply is producing high voltage.

Review Installation Requirements

The air cleaner is installed in place of the main return grille so all the air circulated by the system passes through the air cleaner.

It can be installed in either a wall or ceiling, but not in the floor. See Fig. 5 through 7 for typical installations.

COUNTERFLOW FURNACE

Fig. 7. Typical electronic air cleaner application on counterflow (downflow) furnace.

(Dotted lines show optional ductwork.)

In a wall installation, mount the one-cell air cleaner with the door hinge on the bottom so the air cleaner fits between the two studs 16 in. (407 mm) on center. The two-cell air cleaner fits between two studs 24 in. (610 mm) on center when mounted with the hinge on either side

between three 16 in. studs, with center stud removed, when mounted with hinge on the bottom.

Do not install either unit with the hinge on the top because the cell(s) will be awkward to remove.

Determine Duct Design Requirements

The return duct should end at, or slightly behind, the finished wall surface. Do not use a standard register flange, or the door may not fit tightly against the wall.

Transitions

Transitions are needed when the duct is a different size than the air cleaner. Gradual transitions reduce air turbulence and increase efficiency. The transition should be 20 degrees or about 4 in. per running ft (100 mm per 300 linear mm) or less on each side of a transition fitting.

CAUTION

Electric Shock Hazard. Can cause electrical shock or equipment damage.

Disconnect power before installing air cleaner.

Unpack the Air Cleaner

1. Check that all components are included. The unit

consists of:

• Door assembly in separate box.

• One metal mesh prefilter.

• One or two electronic cell(s).

• Literature package.

2. Lift out and set aside the door/grille assembly and the prefilter. Turn the cell latch (Fig. 4) toward the air cleaner cabinet and remove the electronic cell(s), lifting from the side nearest the latch. Set aside.

3. Remove the four screws holding the wiring compartment cover.

4. Remove the air cleaner cabinet from the carton.

Make Wall Opening

1. Size the wall opening to fit the air cleaner as closely as

possible with the air cleaner door hinge on either side or bottom for the two-cell model, and on the bottom for the one-cell model. See Table 1 for dimensions.
