INTRODUCTION Thru-the-Walt electronic air cleaners are designed to provide maximum air cleaning in applications where a single central rectum air duct is employed, or where the central beating or air conditioning is in a limited access area. The Thru-the-Wall units may be installed in the wail such as in closet Installations or in the ceiling with attic type installations.
HOW YOUR AIR CLEANER WORKS (See figure 1.) Dirt laden air enters the unit from the room. It passes — through the screen (A) first where large particles (hair, lint, etc.) are trapped. Smaller particles {smoke, dust, pollen, tee) pass through this screen and enter the lionizing Section T {B). Here each tiny particle receives a positive electrical men charge. These charged particles then enter the Collection ce Section: {C) which consists of a series of aluminum plates . ..

FRAME Fa ws ASSEMBLY REAR VIEW OF GRILLE AND CABINET Figure 8 MECHANICAL INSTALLATION Remember that allowance must be made for the grille to swing down so that the cell can be removed by puling it straight out of the cabinet. {Figure 8}.
CAUTION: READ INSTALLATION INSTRUCTIONS COMPLETELY BEFORE STARTING THE INSTALLATION. 1. 2 1 Mark the cutout area, {See figures 8 and 12 through 14 for dimensions.) Drill holes at the comers of area to be cut out to permit insertion of saw blade, (See figure 11.) Carefully saw out wall or ceiling area exactly as marked. Remember the frame flange is only wide. It will not cover an oversize or irregular cutout.
_o/15" 8. Prepare air-cleaner cabinet for electrical connection as follows: a. Determine location of power supply source which i : will dictate the location of electrical wiring. " ft, Three knockouts {figure 15) are located in upper right-hand corner of cabinet. A builtin “J” type junction box is included. Secure wiring with accepted hardware, c. The usual knockout location is at upper rear of cabinet, If an obstruction, prohibits this location, use either of the two other knockouts, d.
11. Connect Power Wires, a. Connect black and white wires from power supply to corresponding black and white wires in the air cleaner junction box. {See figure 18.) b. Connect ground wire (green or bare wire) from power source to green grounding wire in junction box. c. install electrical enclosure cover with three screws. {See figures 2.) 12, Install the cell, a. Grasp the cell firmly, holding it at a slight angle with the cabinet {out at bottom). The arrow onto of cell should point inward. b.
OPERATION SAFETY INTERLOCK ON-OFF SWITCH . 1, Turn on furnace or air conditioner to get air flow SWITCH OPERATING LIGHT through the duct. 2. Press the lower section of “ON-OFF” rocker switch no {Figure 21}. 3. Close the grille by rotating into position on the cabinet (fig. 19). Lock in position with two knurled screws. NOTE: Your air cleaner is equipped with an air sensing device.
Figure 23 Figure 24 PREPARE THE WASH WATER: a Place enough hot water in & suitable wash container (figure 23) to cover the cell. b. Dissolve four ounces of automatic dishwasher detergent, such as Categorical, in the water, Liquid detergents used to wash dishes by hand are not strong enough for good clearing, ©. Shake the screen gently outside the house to remove heavy dirt collections. SOAK: a. Lay the cell in the container and allow it to soak for thirty minutes, Bb.
REPLACING AN IONIZING WIRE SUPPORT if one or more ionizing wires in the cell should break, usually caused by accidental damage, it can be replaced as follows: 1. Remove all pieces of broken wire. Make sure supports at each end are in good condition and not bent out of shape. 2. Hock the wire at one end onto the support. 3. Hold a finger against the support at other end {Figure 28} and hold ionizing wire between thumb and forefinger as shown.
