SPARK GUARDIAN™
SAFETY
• Observe the maintenance intervals given in this man-
ual. Overdue maintenance can lead to high costs for
repair and modifications and can render the guaran-
tee null and void.
• During service, maintenance and repair, always use
Personal Protective Equipment (PPE) to avoid injury.
This also applies to persons who enter the work area.
• Use appropriate climbing gear and safety guards
when working on a higher level than 6 feet (local
restrictions may apply).
PERIODIC MAINTENANCE
The Spark Guardian™ and the dustbin require period-
ic maintenance. You must learn from experience how
often this should take place, since the degree of pollu-
tion strongly depends on the welding process and the
intensity of use.
Cleaning of Spark Guardian™
The Spark Guardian™ can be cleaned in two ways:
1. A high-pressure cleaner with hot water
2. Industrial detergent type EFC
To clean the Spark Guardian™, proceed as follows.
1. Support the Spark Guardian™, preferably using a
hoist.
2. Demount the entire Spark Guardian™ by loosening
the duct clamps at both ends.
3. Disassemble the Spark Guardian™.
4. Clean the inlet and outlet of the housing (inside).
Let dry.
5. Assemble and mount the Spark Guardian™ in
reverse order.
Replacing The Dustbin
The dustbin cover is provided with a flexible hose to
facilitate replacement of the dustbin.
To replace the dustbin, proceed as follows.
Without manual damper:
1. Turn off the connected extraction fan.
2. Loosen the quick connect coupling (See Figure D.6,
Item C) and empty in accordance with federal, state
and local codes.
3. Close the dustbin using the lid supplied with the new
dustbin.
4. Install new dustbin and connect it in reverse order.
5. Turn on the extraction fan.
6. Dispose of the used dustbin in accordance with fed-
eral, state or local regulations.
