5. 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 hose to a dedicated fume extractor.
6. Seal all seams and connections tightly.
7. Plug the fan into a grounded outlet. Use a circuit different from the one the engraver will be on.

(5 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. Position the duct fan behind your engraver in the correct direction as per the label on it.
2. Slide a Ø120 hose clamp onto one end of the Ø120 mm, 3 m long exhaust hose. Use it to firmly
connect the engraver’s exhaust port and the hose.
3. Slide the other Ø120 hose clamp onto the other end of the exhaust hose and slide the adapter
ring onto the fan, heating it if necessary. Use the clamp to firmly connect the fan inlet and the
hose.
4. Slide a Ø150 mm hose clamp onto one end of the Ø150 mm, 2 m long hose. Use it to firmly
connect the fan outlet and the hose.
