9. MAINTENANCE
normal maintenance is confined to periodic cleaning of
the ionizer, cell and filters, including checking the drive
belt tension.
A. Cleaning Instructions
Ground the collection cell and ionizer by turning off
unit and depressing both push-to-test buttons. this will
remove any residual charge from components and open
component access door.
remove the dirty collection components (prefilter,
ionizer, cell and afterfilter) from cabinet.
While there are many methods of cleaning, certain key
cleaning criteria contribute to the effectiveness of every
method. these include the type of detergent, detergent
strength, water temperature, agitation/impingement,
duration, rinse procedure and dry-out time.
Type of Detergent.
in general, the detergent used
on most applications will be alkaline in nature. it is
extremely important that the detergent have a built-
in buffering agent to prevent deterioration to the
aluminum. Detergents are available through united air
Specialists for specific applications and contaminants.
Detergent Strength.
Detergent concentration, or
“strength,” in a mixture with water varies with the
application from 1:1 to 5:1 to even 20:1 parts water
to parts detergent, refer to detergent manufacturer’s
directions. More or less detergent may eventually be
required for effective cleaning at reasonable detergent
cost. typically, 20:1 is recommended as a starting point.
Experimentation is recommended.
Never mix acid and alkaline detergent for manual
cleaning. Detergent mixing could cause rapid
heat release, gel formation or other undesirable
conditions.
Water Temperature.
Detergents can be up to twice
as effective in hot water and hot water alone is
very effective in softening built-up residue. Water
temperature should be 130°F (54°C) to 150°F (66°C),
not to exceed 160°F (71°C).
Agitation/Impingement.
these methods are virtually
the same, with impingement being the most extreme
form of agitation. Any liquid movement over built-up
residue will dissolve some of the contaminant, allowing

CAUTION
Hazardous live and moving parts are exposed during
the following procedures. Switch off/isolate the electrical
supply to the Smog-Hog air cleaning System before
servicing.

Cleaning and servicing should only be done by qualified and trained personnel. Some collected contaminants may be
hazardous. consult factory or local safety personnel before servicing unit and for proper disposal of collected contaminants.

risk of electrical shock. a residual Dc voltage will remain
on high voltage components for a short time after power is
removed. Prior to handling, ground components using an
insulated screwdriver, refer to figures 4 and 5.
