only regular maintenance suggested is emitter point cleaning, ion balance checking
and ion output checking, Emitter point cleaning takes only seconds with the patented
point cleaner. The BLOWER OVERHEAD contains an patented balancing circuit
that is inherently self balancing. This circuit compensates for dirt build – up on
emitters, emitter point wear, line voltage fluctuations and variations in air velocity.
Scheduled checking of the ion output and balance should be considered to assure
quality audit requirements.
Emitter Cleaning
To clean the ion emitter points: simply rotate the point cleaner knob located at the
center of the outlet grille clockwise to the stop (approximately one turn)and release,
The spring loaded point cleaning brush will return to its parking spot.
Recommended frequency of cleaning is once a week.
Air Inlet and Outlet Cleaning
The air inlet grille on the rear of the unit and the ionized air outlet should remain
clean to prevent restriction of air flow. They can be cleaned with a soft brush or
vacuum.
Air Filter Cleaning
Remove the air filter from the rear of the unit by unsnapping the filter retainer. Rinse
the filter in plain water while gently squeezing. If the dirt is stubborn, wash the filter
in mild soap and water then rinse. Blot the filter dry with paper towels and allow to
dry. Install filter on air inlet and secure by snapping the filter retainer in place.
IMPORTANT: If an air filter is used, clean the air filter regularly.
Ion Output Check
To test the unit for ion output the use of a charged plate monitor is recommended.
Discharge times can be measured and checked against the Ion Output tables in
Section3, Specifications. If a charged plate monitor is not available, but a static
meter such as a SIMCO handheld electrostatic field meter SHISHIDO electrostatic
Analyzer or warmbier charged plate monitor is available, ion output may be checked
with the following procedure. Take a piece of plastic and rub it with cloth until a
static charge can be read with the static meter. Turn on the BLOWER OVERHEAD
and set the fan speed to high. Hold the plastic one foot away from the ionized air
outlet for five seconds. Remove the plastic from the ionized air stream and measure
the static charge. The plastic should be neutralized.
If no instrumentation is available, the unit’s operation can be verified with the
following procedure. Tear-off about a 10 inch length of transparent tape. Approach
the nonadhesive side of the tape with your free hand note the electrostatic attraction
of the tape to your hand. Pass the tape through the ionized air stream approximately
