MAINTENANCE
- CAUTION -
Always disconnect the power to the AutoClean before working on or near the air cleaner.
WHEN TO WASH THE ELECTRONIC
CELLS
To maintain peak performance and efficiency, the
electronic cells and spray shields in the electronic
air cleaner must be washed regularly. This
washing is necessary to remove the dirt particles
accumulated during the air cleaning process.
The cells and screens should be visually checked
for dirt or lint. Experience will probably be the best
indicator of how often the cells and screens should
be cleaned. For example, when operating in a
thick smoke or particularly dirty atmosphere, the
cells may need washing twice a week. If the dirt
accumulation is light, the period between
washings can be lengthened.
AUTOMATIC WASHING CYCLE
The cell wash cycle for the electronic air cleaner is
controlled by a built-in timer sequence and may be
activated by a master clock. The washing
assembly is operated by a motor. NOTE: For 50
Hz models, the timing will be about one-fifth
longer.
Make sure that enough hot water is available for
washing throughout the entire cycle. In
installations with multiple electronic air cleaners, it
may be necessary to stagger the timing of the
wash cycles. This is to assure adequate water
pressure for washing.
MANUALLY STARTING A WASH
CYCLE
The electronic air cleaner is equipped with an
automatic wash control box. When an extra wash
cycle is desired, it may be manually started by
pushing the labeled button.
NOTE: The complete cycle takes about 70
minutes. For the first 15 minutes when water is
being sprayed in the electronic air cleaner, the
heating or cooling system is automatically turned
off.
While the cells in the electronic air cleaner are
being washed, a musty, dirty odor combined with
the characteristic odor of the detergent may be
noticed. This is caused when the accumulated dirt
on the cells is washed off by the detergent and hot
water spray. It will disappear after the washing is
complete.
