Installation
For best results, remove the built-in fan from your engraving machine or cut its wiring and replace the fan system with this device. Make sure the machine is powered off and disconnected from the power supply before making the mentioned adjustments.
- Find a suitable location to mount the device. This should be somewhere in between your engraving machine’s vent and the desired venting device or area. Make sure the location and mounting surface are able to support the weight and dimensions of the duct.
- Use the preassembled bolts to attach the mounting bracket to the fan.
- Attach the fan by its mounting bracket to your chosen surface. Use the provided foam pads between the mount and the mounting surface. Pay attention to the exhaust and intake sides of the fan.
- Connect the fan to your venting device or area and to your machine using your ducts (not included). You either need two ducts or you have to measure and cut one long duct to attach its halves to either side of the fan, while making sure the entire duct system can reach your machine’s exhaust and your venting device or area. Use clamps (not included) to secure the connections.
Operation
Make sure that the voltage leading to the fan matches the level it is rated
for.
Plug in the fan. Turn its rotary knob clockwise until the fan activates at its
highest speed. Continue turning the knob clockwise to decrease its rotational
speed if desired. Turn the knob completely counterclockwise to turn off the
fan.
Maintenance
The exterior of this device can be cleaned with a soft damp cloth. DO NOT use
abrasive cleaners or caustic chemicals.
Any internal maintenance should be done by a trained technician. For best
results, periodically have the blades, rotors, and other internal components
dusted and cleaned. During cleaning, have the parts checked for any looseness,
wear, or damage and correct any problems before further use.
