3. Noisy or unstable electricity and voltage spikes may cause interference and possible damage to the
electronics of the laser system. If electrical power fluctuations, brownouts 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.
4. The laser system is designed as a Class I, Group A, pluggable device. It is also designed for
connection to IT Power systems which provide the most flexibility to the user.
Exhaust System (User Supplied)
1. We recommend you consult with a licensed contractor to meet local safety and building code
requirements.
2. The exhaust system must be capable of supplying a minimum of:
a. VLS3.75 and VLS4.75 - 250 CFM (cubic feet per minute) of airflow while under a load of 6 inches
of static pressure (425m3/hr. at 1.5kPa)
b. VLS6.75 - 500 CFM (cubic feet per minute) of airflow while under a load of 6 inches of static
pressure (850m3/hr. at 1.5kPa)
3. Do not install forward incline, backward incline, in-line or ventilator fans because these types of air
handlers are inadequate and inappropriate for this type of installation. A high-pressure blower must
be used to meet minimum airflow requirements.
4. For personal safety and noise control, we recommend that the exhaust blower be mounted outside
the building.
5. Rigid tubing should be used for the majority of the connection between the blower and the laser
system. The tubing should be smooth-walled and have as few 90-degree bends as possible.
6. Install an exhaust gate to adjust airflow and to close off the exhaust when the laser is not in use.
Place this gate near the laser system within 5 to 10 feet (1.50 to 3.00 meters).
7. Use a short piece of industrial-grade, wire-reinforced rubber tubing to connect each laser system
exhaust port to an exhaust gate and secure with a hose clamp. This will isolate exhaust blower
vibrations from your laser system.
8. Wire the exhaust blower electrically to a wall switch in the same room for easy ON/OFF control.
Note: The following diagram shows a typical exhaust system layout. Use this as a guideline for proper
exhaust system installation. Although this diagram serves as an example, we recommend you consult with a
licensed contractor to meet local safety, environmental and building code requirements and to also
calculate the correct size blower required for your particular installation. Length of exhaust pipe, exhaust
pipe diameter, number of 90-degree angles and other restrictions must be calculated when determining the
correct exhaust blower unit. Installing an undersized or oversized blower is not only unsafe but can also lead
to excessive wear and tear to the laser system and premature failure.
