the unit so that the flange is flush with the underside
of the ceiling.
Leave enough room around the Air Cleaner for
removal of collecting cell and prefilter.
7. Replace the cell, prefilter and cover. Hook up the
safety chain to the cover.
Do not hang the unit with chain only. This will not
give the unit the necessary stability when removing
the cells or servicing the unit.
Wiring
All wiring must comply with applicable codes and
standards. See unit rating label for correct voltage and
amperage.
1. Two knockouts are provided, one on top and one on
the side of the unit, adjacent to the wiring
compartment. For convenience, a wall switch may be
installed near the Air Cleaner, in series with the
power source, to turn the unit on and off.
2. Remove the cover of the wiring compartment to
locate the input leads and ground stud. The Air
Cleaner must be grounded for proper operation and
safety.
3. Once the unit is mounted and wired, the cover can be
replaced on the hinge and the chain replaced on the
"S" hooks. Close the cover by sliding the levers
toward the center and pushing the cover up into
place. Release levers to lock the cover into place.
For information on wiring the remote switch
control see page 7.
OPERATION & MAINTENANCE
Operation Check
1. With the cell and prefilter in place and the cover
closed, turn the system switch ON.
2. Adjust the fan speed with the slide switch. Insure the
unit functions on all speeds.
3. The performance light should be ON, which indicates
the power board is functioning properly.
4. If the unit is not functioning properly see the
"Troubleshooting Guide"
When the Air Cleaner is new it may arc or periodically
make "snapping sounds". A slight odor of ozone may be
noticeable. The arcing and odor are due to rough edges
and burrs on the cell. These symptoms will disappear
during the first few weeks of normal operation. The ozone
levels are well below government standards for indoor air
concentration.
Maintenance Schedule
The collecting cell and prefilter must be cleaned on a
regular basis for the unit to function at its peak efficiency.
The frequency of cleaning will vary from one environment
to another. The following is an average wash cycle:
Stores, Offices, Computer & Conference Rooms = 4
Weeks
Cafeterias, Restaurants, Lounges = 3-4 Weeks
Bars, Bingo halls = 1-3 Weeks
The unit should be checked on a regular basis to
determine the frequency of cleaning required in each
location and a cleaning schedule established.
Cleaning
1. Turn off the system switch and wait 15 seconds for
high voltage to dissipate.
2. Open the cover and cell access door and remove
collecting cell and prefilter. Cell plates are sharp.
Handle with care.
3. Place cell in tub and spray completely with DAX
Detergent, allowing detergent to run down both sides
of plates and ionizing wires. Let sit for 5 minutes.
Rinse cell well with hot water (140ºF / 60ºC
maximum). Repeat washing process if necessary.
4. If dirt or nicotine remains on plates, let cell soak in hot
soapy water for 30 minutes. Never use any
instrument to clean the cell, as this may damage
the ionizing wires or bend cell plates.
5. Spray prefilter with DAX Detergent and rinse well.
6. To dry cell, tilt on 45º angle against wall with the
arrow pointing sideways. Allow to dry completely for
10-24 hours. Place in sunlight for faster drying time.
7. When the cell and prefilter are dry, place them back
into the unit. The arrow on the cell points up. The red
fiberboard on the cell should line up with the contacts
in the cabinet. Close door and cover. If the cell arcs
when the switch is turned on or if the performance
light does not come on, then the cell may be still wet.
Allow more time for drying.
The use of DAX Detergent is strongly recommended
for cleaning as it is a heavy-duty solution used expressly
for removal of accumulated pollutants on cell plates. If
used as directed, DAX will not harm aluminum or steel.
Any problem arising out of the use of another cleaning
agent will void the warranty. Do not use detergents that
WARNING
Electrical shock can cause injury or death. Be certain
main line disconnect switch is off before wiring. CAUTION
Make sure Air Cleaner switch is OFF before
performing any maintenance or removing any
components.
CAUTION
Damage to cell may occur if improperly handled or
washed. Do not wash cell in a dishwasher. Never
use any object to clean between the cell plates, as this
may cause damage to plates or ionizing wires. Never
place cell in oven to dry. The edges of the cell may be
sharp - handle with care.
