UNPACKING AND INSPECTIONUNPACKING AND INSPECTIONUNPACKING AND INSPECTIONUNPACKING AND INSPECTIONUNPACKING AND INSPECTION

1. Unpack and carefully remove air cleaner fromcarton.

2. Stand air cleaner upright on floor.

3. Release two knurled screws (Fig. 2) at upper edgeof grille, open grille and slide it out of hinges atbottom by moving it to the left.

4. Rotate two screen retainer latches either left orright to clear screen. Lift screen out.

5. Remove three screws, one at each end and one atcenter of electrical enclosure cover and removecover.

Dirt laden air enters the unit from the room. It passesthrough the screen (A) first where large particles (hair,lint, etc.) are trapped. Smaller particles (smoke, dust,pollen, etc.) pass through this screen and enter theIonizing Section (B). Here each tiny particle receives apositive electrical charge. These charged particles thenenter the Collection Section (C) which consists of aseries of aluminum plates...alternate plates arecharged positive. See Figure 1.

The positive charged particles are repelled by thepositive plates and attracted to the negative plateswhere they are collected — just as a magnet attractsiron filings.

LOCATING THE AIR CLEANERLOCATING THE AIR CLEANERLOCATING THE AIR CLEANERLOCATING THE AIR CLEANERLOCATING THE AIR CLEANER

Your Thru-The-Wall Electronic Air Cleaner is mountedat the return-air duct inlet. (See figures 4 through 7.) Itworks equally well in either high or low wall installa-tions, or in the ceiling. It can be used with any type offorced-air heating or cooling system.

In most cases, return-air ducts are located just insidethe wall (or ceiling) grille. When the air cleaner is flushmounted, it will extend through the wall cutout and intothe return-air duct. If the return-air duct is located at adistance from the wall (or ceiling), extend a connectingduct to the rear of air cleaner frame with sheet metalscrews.

NOTENOTENOTENOTENOTE: Always tape all ductwork joints with duct tapeto prevent dirt-laden air from entering ducts.

After deciding upon the exact location, make sure ofthe following before cutting out wall or ceiling area:

1. Exact location of return-air duct behind wall (orceiling).

2. Location is free of obstructions, such as steelsupport beams, piping or electric wiring.

3. Access to inner area for wiring connections.

4. Return-air duct is deep enough to accommodate aircleaner (6 inches, see figures 4 through 8.)

5. Enough room is left at a corner or wall offset topermit installation of the grille. (See figure 8.)

Remember that allowance must be made for the grilleto swing down so that the cell can be removed bypulling it straight out of the cabinet. (Figure 9).

DUCT WORK CONNECTIONDUCT WORK CONNECTIONDUCT WORK CONNECTIONDUCT WORK CONNECTIONDUCT WORK CONNECTION

If the duct work to be used is larger or smaller than therecommended framing sizes, a transition should beinstalled between the duct work and the air cleaner toinsure maximum filtering efficiency. The expansion orcontraction rate of the transition should not exceed theratio of 1 to 3. (See figure 10.)

Once the duct connection to the framing is completed,the air cleaner frame (cabinet) may be inserted into theframing cavity.

Before inserting the cabinet, one of the three knock-outs (figure 15) should be removed for insertion of the120 VAC input wiring.

After properly positioning the cabinet, it may be fas-tened to the framing either by using the mounting holesin the inside walls of the cabinet or the mounting holesin the front flanges of the unit.

1. Mark the cutout area. (See figures 8 and 12 through14 for dimensions.)

2. Drill holes at the corners of area to be cut out topermit insertion of saw blade. (See figure 11.)

3. Carefully saw out wall or ceiling area exactly asmarked. Remember the frame flange is only 3/4inch wide. It will not cover an oversize or irregularcutout.

4. Figures 12, 13 and 14 show several possiblesituations that will be apparent when the cutout isfinished. With standard stud spacing you will runinto either one or two studs. They must be cut andthe section removed at air cleaner location.

5. Install headers all around air cleaner opening (foursides). This will provide good support of air cleanerand restore the original wall strength. Use basicconcepts shown in figures 12 through 14 if your walldiffers from the diagrams shown.

NOTENOTENOTENOTENOTE: The same method for framing the air cleanercutout can be applied to ceiling joists, when a ceilinginstallation is required.

6. Cut out required opening in return-air duct. The ductcutout should fit air cleaner cabinet as closely aspossible. If duct is more than six inches from wallsurface, install a connecting duct between aircleaner cabinet and existing duct. (See figures 5and 6.)

7. Slide the frame assembly into the finished cutout.Make sure it fits properly, then remove it.

8. Prepare air-cleaner cabinet for electrical connectionas follows:

a. Determine location of power supply sourcewhich will dictate the location of electrical wiring.

b. Three knockouts (figure 15) are located in upperright-hand corner of cabinet. A built-in “J” typejunction box is included. Secure wiring withaccepted hardware.

c. The usual knockout location is at upper rear ofcabinet. If an obstruction prohibits this location,use either of the two other knockouts.

d. Allow at least 10 inches of wire lengths on insideof cabinet for connection to air-cleaner wires.

9. Connect air-cleaner to existing wiring.

Wiring to the air cleaner must comply with localelectrical codes. For this reason, specific wiringinstructions are not given. The color coding of wiresout of the junction box are white (120V) or red (220V)and black. They should be matched to wires of thesame color from electrical power source figure 18).Connect ground wire from power source directly tothe green grounding wire provided in the junctionbox area.

This Thru-The-Wall electronic air cleaner may beequipped with a solid state Air Flow monitor (figure16) that will automatically turn your air cleaner ONor OFF whenever the furnace fan is running.

10. Install frame assembly in wall opening:

a. Slide air cleaner cabinet into wall opening.

b. Secure the cabinet in opening with nails, orscrews, through the 12 holes provided in faceof flange (figure 17), or through holes in cabinetwalls.

CAUTION: On ceiling installations, be sure touse all 12 flange holes to support full weight ofair cleaner.

c. If an extension duct is required, install it now.

d. Reach through air cleaner cabinet and tape alljoints made into ductwork.

2. Press the upper section of “ON-OFF” rocker switch(figure 21).

3. Close the grille by rotating into position on thecabinet (figure 19). Lock in position with twoknurled screws.

NOTENOTENOTENOTENOTE: If your air cleaner is equipped with an airsensing device, it may provide a short delay before theoperating light comes on.

IMPORTANTIMPORTANTIMPORTANTIMPORTANTIMPORTANT: Occasionally, you will hear a sharpsnapping sound (called arcing) coming from the aircleaner. Arcing is a normal phenomenon. It can resultfrom the collection of especially large particles. Itoccurs more often in a new installation. Later on,arcing may occur when the cell has become loadedwith dirt and needs washing, or when still damp afterwashing. The presence (or absence) of this soundnormally does not mean that the unit is defective.

7. PREPARE THE WASH WATER:

a. Place enough hot water in a suitable washcontainer (figure 23) to cover the cell.

b. Dissolve four ounces of automatic dishwasherdetergent, such as Calgonite, in the water.Liquid detergents used to wash dishes by handare not strong enough for good cleaning.

c. Shake the screen gently outside the house toremove heavy dirt collections.

8. SOAK:

a. Lay the cell in the container and allow it to soakfor thirty minutes.

b. Then slosh the cell up and down in the solutionuntil it appears clean. Remove cell from thecontainer.

c. Ionizing wires may become coated, causing lossof cleaning ability by the collecting cell. Using adamp cloth, wipe each ionizing wire, exercisingcare not to damage them.

d. Then slosh the screen up and down in thesolution until clean. Drain out the dirty water.

9. RINSE:

a. Hold cell upright in container.

b. With a hose, rinse with warm water. (Seefigure 24.)

c. The hose nozzle should be held approximatelyten inches from cell plates and at a slight anglefor better cleaning effect. Rinse both sides ofcell until water is clear.

d. Flush cell frame along edges to dislodge anytrapped dirt or lint.

e. Flush and rinse screen on both sides.

f. Stand cell and screen up and allow them todrain for 2 hours.

10. WHITE DUST (LINT)

An Electronic Air Cleaner is designed to collect twomajor types of contaminants:

a. Irritants (Pollens Spores, Molds, Bacteria, etc.)

b. Black soiling contaminants (Dirt and Smokeparticles.)

The residue on the collecting plates of an electronic aircleaner is black, indicating it is removing dirt from theair stream. After installing an air cleaner you maynotice white dust (typically long linty particles or fibers:from carpets, cotton materials or drapery fabrics.) Thismaterial is not collected by the air cleaner because itdoes not contain the irritants or soiling contaminantslisted above or settles out of the air before reaching theair cleaner. The presence of white dust does notindicate an air cleaner requires service.

11. INSTALL CELL

CAUTIONCAUTIONCAUTIONCAUTIONCAUTION: When installing the cell in a ceiling installa-tion, make sure it is latched securely in place beforereleasing it. (See figure 20.)

a. Grasp the cell firmly, holding it at a slight anglewith the cabinet (out at bottom). The arrow ontop of cell should point inward.

b. Insert cell at the top and engage retaining pins(figure 19) into their respective cell retainingslots, then slide cell outward until retaining pinsare at bottoms of slots.

c. Allow cell to swing inward at the bottom, pushingslightly until it “clicks” over the safety spring clipat bottom center of cabinet.
