2. Restore power to system.
3. Move ON-OFF switch on power door to ON position.
4. Set room thermostat to start blower.
5. Check to see if operation light is glowing. This indicates
proper power to the cells.
NOTE:
Leave these Installation Instructions with the owner to
enable the owner to perform routine maintenance and service.

ROUTINE MAINTENANCE AND SERVICE
Your new EAC requires periodic maintenance for optimum
performance. You may perform this service or have your service-
man handle it for you.
Cleaning of the cell assembly and pre-filter is required 2 or 3 times
a year. Frequency will depend on size of home, number of
occupants, smoking habits, etc.
The odor of ozone may be noticeable during operation of an EAC.
A somewhat higher ozone generation rate during the first week or
2 of operation may be caused by sharp edges on some of the new
high-voltage parts. Normal use dulls these sharp edges in a short
time.
The odor of ozone is detectable by an average person at levels as
low as 0.0030 to 0.010 parts per million (PPM). The concentration
of ozone produced in a home by an EAC ranges from 0.006 to
0.020 PPM. Average concentration of ozone in the air of major
cities ranges from 0.020 to 0.040 PPM and even higher. This is
well above the level produced by an EAC.
Because normal maintenance (cleaning) is so simple, most home-
owners will choose to personally perform the necessary operations.
Clean the unit where dust from air cleaner cells will not soil
carpets or floor.
CAUTION:
Before removing the electronic cells, be
sure to de-energize the system fan to avoid any possibility
of circulating unfiltered air back into the system.
To gain access to the pre-filter and air cleaner cells, simply push
power switch to OFF position and remove the power door. Lay it
to the side. Pull out the first-stage pre-filters and vacuum from
entering-air side, or wash in detergent and water. Allow to dry
thoroughly. Reinstall. Do not spray pre-filters with any filter
coatings.
