To install the external fan:
1. Attach one of the provided Ø150 mm
exhaust hoses directly onto the exhaust vent
on the rear of the engraver, fastening it into
place with one of the hose clamps.
The hose can be expanded to a full length of
about 5 feet (1.5 m).
2. Fastened the other end onto the external
fan’s inlet with a second hose clamp.
3. Attach the second duct onto the fan’s outlet
with a third hose clamp.
It can also be extended to a length of about
5 feet.

4. Fit the other end of the duct into a dedicated purifier, or directly place it out a window if the
fumes are not hazardous and meet local and national air safety standards.
5. If additional ducts are necessary, ONLY use metal material ducts.
Nonconductive materials such as PVC pipe cannot be safely grounded and can build dangerous
static electric charges during use.
6. Seal all seams and connections tightly.
NEVER operate the laser if the fan and ducts are not working to purify or remove
the fumes produced by the target material. Research materials before use
and never operate the laser on any (such as PVC, Teflon, and other halogen-
containing substances) that can produce corrosive, hazardous, or even deadly
fumes.
