MAINTENANCE OF CELLS

Washing Cells and Prefilters

Regular washing is necessary to ensure proper performance (see

Fig. 11). A thorough wash ing once every two months will be

adequate for most installations. More frequent washing (once a

month) may be necessary on some installations (new homes for

example) where there is new carpeting, plaster dust, or excessive

cigarette smoke.

To remove cells and prefilter

1. Push air cleaner switch to the OFF position. Wait 15

seconds. Open door access panel.

2. Carefully remove cells and prefilter(s) and set aside in a safe

place.

3. Do not drop the ionizing--collector cell. This could cause

damage to the cell plates or ionizing wires and cause

excessive arcing and noise.

To wash cells and prefilter(s)

To wash cells and prefilter(s) We suggest that you follow the

instructions below to properly and thoroughly clean your collector

cells.

1. Place enough hot water in a utility tub to cover the first cell.

Dissolve 2 to 4 oz. of granulated automatic dishwasher

detergent (not laundry detergent) in the water.

2. Allow the cell to soak for 30 minutes. Agitate it up and

down in the solution until it appears clean and remove.

3. Repeat with second cell.

4. Agitate the prefilters up and down in the solution until they

appear clean.

5. With a hose, rinse the cells and prefilters. The hose should

be held about 10” (254 mm) from the cell plates and at a

slight angle for better cleaning results. Be careful not to

spray the ionizing wires directly with the hose. The water

pressure can cause the wire to snap and break. The cell

frame should be thoroughly rinsed along the edges to

dislodge any trapped lint or dirt. Carefully wipe a damp

cloth or sandpaper (not emery cloth) along the ionizing

wires.

6. Stand cells and prefilters up to drain. Let dry two hours.

You may experience a slight discoloration of the aluminum

collector cells after washing. This is a normal chemical

reaction and will not harm your unit or affect its

performance.

To replace cells in air cleaner

1. Replace prefilter and cells in cabinet. Check that arrow on

cells points in same direction as air flows through the duct

(If you have to force it past the positioning screw on

bottom, it is probably in the wrong position).

2. Replace access door (engage tabs on lower edge of door

into slots in cabinet). Carefully close door.

3. Turn air cleaner switch to ON.

TROUBLESHOOTING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury

or death.

The following procedures could expose hazardous live

components. Only a trained, experienced service person

should install this electronic air cleaner. When the circuit has

been de--energized, always discharge any residual current in

the secondary with an insulated handle screwdriver. Always

ground power supply and ionizing--collecting cell when bench

testing. Before performing installation, service or maintenance

operations on unit, turn off all power to unit. TAG

DISCONNECT SWITCH WITH LOCKOUT TAG.

WARNING

Recommended Service Tools

1. Screwdriver, 8” common with insulated handle (plastic)

2. Screwdrivers Phillips #1 and #2 with plastic insulated

handles

3. Needle nose pliers

4. Multimeter

5. High voltage probe

Indication of Electrical Trouble

The air clean er is equipped with a Red CELL ENERGIZED light

for indicating proper unit operation. When the unit is in normal

operation (with the HVAC system fan running, access door in place

and rocker switch in the ON position) and the Red CELL

ENERGIZED light is not lit, the problem is a shorted secondary.

Although failure of the indicating light itself should not be

overlooked, this condition is unusual and rather remote.

Primary Circuit with Blower Operating

If there is supply line voltage at the connections and no input

voltage to the power supply, the outage can be located by checking

operation of the safety switch and the interconnecting wiring with a

multimeter . Refer to Circuit Diagram, to check operation of the

switches. Following these steps to test for proper operation of the

circuit board and power supply assembly:

1. Ensure that the circuit breaker controlling the furnace

blower is in the ON position and the main fuse is not open.

2. The power supply board has a built-- in internal fuse to

protect the 24V transformer . It can be checked visually by

inspecting the fuse. If the fine wire inside the fuse is broken,

this indicates a problem in the 24V circuit of the power

supply board. Do NOT replace this fuse. The entire power

supply board must be replaced. The purpose of the fuse is

not to protect the power supply board, but to function as a

troubleshooting feature of the product and to protect the

transformer from damage.
