SETUP
Setting up Exhaust Management
Method A: Onboard Fan
Exhaust management method A uses the
Onboard Fan to vent exhaust to the
outside of the building. The Exhaust Hose
is provided for your convenience and
should only be used for temporary
operation. For permanent installations, use
smooth hard duct to decrease resistance
to exhaust flow. When using the onboard
fan be sure to choose correct ventilation
option on the Touch Screen during the
Dremel LC40 Laser Cutter startup
sequence. The instructions provided below
are for installing the materials provided by
Dremel. Consult manufacturer instructions
for all other materials.
Items supplied with Dremel LC40 Laser
Cutter: (1) 10 ft. Exhaust Hose & (2) Hose
Clamps.
Additional items needed: Exhaust Vent
Hood, building code approved sealant or
duct tape, materials as needed per Vent
Hood installation instructions and relevant
building and fire codes.
1. Identify an exhaust discharge point that
complies with exhaust discharge
requirements listed above. Ensure that
no more than 10 feet of exhaust duct is
needed between the Dremel LC40 Laser
Cutter and the discharge point.
2. Select Exhaust Vent Hood that complies
with exhaust discharge requirements
listed above. Install Exhaust Vent Hood
according to the manufacturer’s
instructions and relevant building and
fire codes.
3. Attach the Exhaust Hose to the Dremel
LC40 Laser Cutter Exhaust Shroud with
the Hose Clamp provided.
4. Extend the Exhaust Hose the required
length to reach the Exhaust Vent Hood
keeping it as straight as possible.
• All bend radii must be at least two
times the duct diameter.
• Minimize the number of 90-degree
bends; no more than two (2) 90-
degree bends may be used.
• 90-degree bends must be at least 20
inches away from Onboard Fan.
5. Cut the excess Exhaust Hose off with
wire cutters so that only the minimum
required length is used.
6. Securely connect the end of the Exhaust
Hose to the Exhaust Vent Hood with
included Hose Clamp. Stretch the duct
and keep it as straight as possible to
improve exhaust flow through the duct.
