Exhaust System (User Supplied)
We recommend you consult with a licensed contractor to meet local safety and building code requirements.1.
The exhaust system must be capable of supplying a minimum of:2.
VersaLASER VLS3.60 and VLS4.60 - • 250 CFM (cubic feet per minute) of airow while under a load of 6 inches
of static pressure (425m3/hr at 1.5kPa)
VersaLASER VLS6.60 - • 500 CFM (cubic feet per minute) of airow while under a load of 6 inches of static
pressure (850m3/hr at 1.5kPa)
Do not install forward incline, backward incline, in-line or ventilator fans because these types of air handlers 3.
are inadequate and inappropriate for this type of installation. A high-pressure blower must be used to meet
minimum airow requirements.
For personal safety and noise control, we recommend that the exhaust blower be mounted outside the building.4.
Rigid tubing should be used for the majority of the connection between the blower and the laser system. The 5.
tubing should be smooth-walled and have as few 90-degree bends as possible.
Install an exhaust gate to adjust airow and to close o the exhaust when the laser is not in use. Place this gate 6.
near the laser system within 5 to 10 feet (1.50 to 3.00 meters).
Use a short piece of industrial grade, wire-reinforced rubber tubing to connect the laser system’s exhaust port 7.
to the exhaust gate and secure with a hose clamp. This will provide some mobility for your laser system and will
isolate exhaust blower vibrations from your laser system.
Wire the exhaust blower electrically to a wall switch in the same room for easy ON/OFF control.8.
For your system’s electrical requirements, please refer to the “INPUT POWER” label near the power inlet.1.
CAUTION:2. Never remove the ground lead to the electrical cord and plug the VLS
system into a non-grounded outlet. A laser system that is not properly grounded is hazardous and
has the potential to cause severe or fatal electrical shock. Without proper grounding, the laser system may exhibit
sporadic or unpredictable behavior. Always plug the system into a properly grounded (earthed) outlet.
Noisy or unstable electricity and voltage spikes may cause interference and possible damage to the 3.
electronics of the laser system. If electrical power uctuations, brown outs or constant power outages are a
problem in your area, please contact your local Electrician to supply a power isolation and regulation module.
Electrically noisy equipment, such as equipment with large motors, can also cause interference if plugged into
the same outlet. It may be necessary to attach the laser system to a dedicated electrical line to resolve the
problem.
The laser system is designed as a Class I, Group A, pluggable device. It is also designed for connection to IT 4.
power systems which provide the most exibility to the user.
