SECTION 7 Maintenance
The Aerostat XC has been designed with low maintenance in mind. The only regular
maintenance suggested is emitter point cleaning, ion balance checking and ion output
checking. Emitter point cleaning takes only seconds with SIMCO’s patented point
cleaner. The Aerostat XC contains a 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.
CAUTION! ELECTRICAL SHOCK HAZARD!
Do not insert objects through intake or outlet grille.
7.1 Emitter Cleaning
To clean the ion emitters, simply sweep the emitter cleaner back and forth once across
the ionized air outlet. Recommended frequency of cleaning is once a week.
7.2 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.
7.3 Optional Air Filter Cleaning
Remove the air filter from the rear of the unit by sliding the aluminum frame of the filter
towards the rear of the unit. 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. Reinstall filter on air inlet by sliding it under brackets
from rear of the unit.
IMPORTANT
: If an air filter is used, clean the air filter regularly.
7.4 Ion Output Check
To test the unit for ion output, the use of a charge plate monitor such as the SIMCO
EA-4 is recommended. Discharge times can be measured and checked against the Ion
Output tables in Section 3, Specifications. If a charge plate monitor is not available, but
a static meter such as a SIMCO handheld electrostatic fieldmeter 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 Aerostat XC.
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 XC’s operation can be verified with the following
procedure. Tear off about a 10-inch length of Scotch® brand (or equivalent) transparent
tape. Approach the non-adhesive side of the tape with your free hand and note the
electrostatic attraction of the tape to your hand. Pass the tape through the ionized air
stream approximately 1 foot from the unit and again approach the non-adhesive side of
the tape with your free hand. If the tape has been neutralized, it will not attract.
