3.4 Installing the Exhaust System

Wear work gloves to avoid cuts.
The provided exhaust pipe extends to a total length of 9.8 ft (3 m). Plan out the route that they will
take from your engraver's fan to a dedicated purifier or—if your engraving fumes and debris will
not be hazardous and meet local and national air safety standards—to any window or exterior vent.
Generally speaking, the straighter you can keep the pipes between your engraver and their outlet,
the better your system's ventilation will be and the less quickly dust and debris will build up within the
pipes over time.
To install the duct fan:
1. Slide one of the hose clamps onto one end of the exhaust pipe and directly attach the exhaust
pipe onto the exhaust vent on the rear of the engraver, fastening it into place with the hose clamp.
2. Fasten the other end onto the exhaust fan's inlet with a second hose clamp.
3. Connect another exhaust pipe to the exhaust fan's outlet with a third hose clamp.
4. Place the other end of the hose out a door, window, and so on, or—if there will be any harmful
byproducts produced as you engrave— connect the pipe to a dedicated fume extractor.
5. Seal all seams and connections tightly.
NEVER operate the laser if the exhaust system is not removing the fumes
and dust produced by your materials out of your work area. Always 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.
