UAS technicians are available for system service at a
daily rate plus travel and expenses.
5.2
Start-Up
Depending upon specifications (by others), the SMOG-
HOG
®
system may be electrically interlocked placing the
SMOG-HOG
®
system on-line automatically or by a push
button. At start-up, all indicator lamps should illuminate
to the power pack enclosures. If an indicator lamp(s)
fails to illuminate, check that the toggle switch is in the
on position to the power pack enclosure. If indicator
lamp still will not illuminate, refer to Section 7,
Troubleshooting.

MAINTENANCE AND MANUAL
CLEANING
THE FOLLOWING SECTIONS ARE FOR THE USE OF
TRAINED PERSONNEL ONLY.
6.1
Routine Maintenance
Once the system is operational, periodic maintenance is
necessary to assure peak performance. Follow a
common sense pattern of observation and log abnormal
conditions. Since systems reflect the process under
control, maintenance patterns will vary accordingly.
System Checklist. The following is a checklist for
maintaining your SMOG-HOG
®
:
Check Power Pack Indicator Lamps Daily. Blinking,
dim or extinguished indicator lamps indicate abnormal
functioning of an operating module. If the indicator
lamps seem abnormal, proceed with component check
below and/or refer to Section 7 “Troubleshooting.”
Check Component Appearance Weekly. With all
indicator lamps illuminated, a quick check of a few
modules could show symptoms of a growing problem or
confirm if manual cleaning is required.
To check the condition of the ionizers and collector cells,
place the system off-line. Open the component access
door and ground the ionizer wire support bar and the
collector cell, refer to Figures 2 and 3. Note the
condition of the door feed-through insulators and
cabinet walls. Experience will dictate whether
contaminant buildup seems excessive or not.
Remember, dirty insulators and components cause a
high voltage reduction. Whenever opening a component
access door, clean the door feed-through insulators.
Remove both ionizers from the module, noting the
condition of contact springs (distorted? skewed?),
standoff insulators (dirty?), and ionizer wires (broken?
sagging?). Wires should be taut and centered between
ground plates. Remove both collector cells from the
module, noting the condition of contact springs
(distorted? skewed?), cell plates (dirty? bent?
skewed?), triangular insulators (dirty?).
Ionizer and collector cell cabinet tracks should be free of
contaminant buildup, providing a good ground contact.
Aluminum filters should be clean enough to allow air to
pass through freely. They should be in line with their
frames and not sagging in the direction of airflow.
Sumps should be free of debris and any standing water.
Door flange gasket should be in place and in good
condition.
If, after following these guidelines, the problem is not
apparent, refer to Section 7, Troubleshooting, or place
the toggle switch to the power pack enclosure in the off
position, eliminating undue power pack stress. Note the
condition and schedule troubleshooting.
6.2
Manual Cleaning of SMOG-HOG
®
Components
While there are many methods of manual 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.
!
C A U T I O N
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.
!
C A U T I O N
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 2 and 3.
!
NOTICE
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.
