Adjust thermostat so system blower is "ON."
1. Both input indicating light (green) and output voltage light
(red) should now be on.
2. Check to assure that both lights go out when the cell access
panel is removed, when rocker switch is switched to "OFF"
position, and when system blower is not running.
MAINTENANCE
Sharp edges. Handle the cells carefully to avoid cuts from the
sharp metal edges.
Step 1—Washing Cells and Prefilters
Regular washing is necessary to insure proper performance. A
thorough washing every 2 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 carpet, plaster dust, or there is above normal cigarette
smoke. (See Fig. 16.)
1. Remove cells and prefilters.
a. Push air cleaner ON/OFF rocker switch to "OFF." Wait 15
sec. Open access door.
b. Carefully remove cells and prefilters, and set aside.
c. Avoid damage to cell plates and ionizing wires.
2. Wash in tub.
a. Place enough hot water in utility tub to cover cell.
Electronic Air Cleaner concentrate solution (Part No.
P902-2001) is recommended. (Solution is available from
your dealer through the Replacement Components Divi-
sion.) As an alternative, 2 to 4 oz of automatic dishwasher
detergent (not laundry detergent) can be used.
b. Allow cell to soak for 30 minutes. Agitate cell up and down
in solution until it appears clean, then remove.
c. Repeat with second cell.
d. Agitate prefilters up and down in solution until they appear
clean.
e. With hose, rinse cells and prefilters. Hose should be held
about 10 in. from cell plates and at slight angle for better
cleaning results. Cell frame should be thoroughly rinsed
along edges to dislodge any trapped lint or dirt. Carefully
wipe damp cloth or sandpaper (not emery cloth) along
ionizing wires.
f. Stand cells and prefilters up to drain. Let dry 2 hr.
NOTE:
We do not recommend washing electronic air cleaner
cells in the dishwasher.
Not only can collector plates and ionizing wires be easily dam-
aged, but dirt from cells and prefilters can permanently stain
plastic dishwasher linings.
3. Replace cell and prefilters.
a. Replace prefilters and cells in cabinet. Check that arrow on
cells points in same direction as air flows through duct. (If
you have to force it past the positioning screw on bottom,
it is probably in a wrong position.)
b. Reposition access door (engage tips on lower edge of door
into slots in cabinet). Carefully close door.
c. Turn air cleaner switch to "ON."
