Troubleshooting guide

2-2 Installation
• If electrical power fluctuations, brown outs, or constant power outages are a problem in your
area, an electrical line stabilizer, UPS (Uninterruptible Power Supply), or backup generator
might be required. If installing any of these devices, make sure that they meet the electrical
requirements of the laser system.
• Never remove the ground lead to the electrical cord and plug the system into a non-
grounded outlet. This is very dangerous and can lead to a severe, if not fatal, electrical
shock. Always plug the system into a 3 prong grounded outlet.
• Do not operate the laser system near devices that give off high levels of radio
frequency (RF) emission. High levels of RF will interfere with the operation of the laser
system and can damage your system or seriously effect your engraving or cutting quality.
If the above requirements cannot be met, you may need the services of a qualified, licensed
electrical contractor to certify your installation. Remember, it is your responsibility to provide a
quality electrical source. Damages to the laser system due to neglect, abuse, or improper
or unsuitable electrical supply will not be covered under warranty.
Exhaust Requirements
• The exhaust blower MUST be mounted on the OUTSIDE of the building either on the roof or
on a cement pad next to the building. It may be necessary to mount the blower on vibration
dampers.
• The exhaust system MUST be capable of supplying a minimum of 150 CFM (cubic feet per
minute) @ 6 inches of static pressure (water). In order to meet the laser system’s CFM
requirements, a high-pressure, high static pressure rated, exhaust blower must be installed.
This type of blower has self-cleaning blades and can maintain airflow even though
restrictions are introduced. 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 incorrect or undersized blower is not only unsafe, but it can
also lead to premature and excessive wear and tear to the laser system. We recommend
that you hire a certified and licensed contractor to design and install your exhaust system.
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. If your contractor has any questions concerning blower specifications or
exhaust system requirements, please contact our Service Department directly before
installation.
• Rigid tubing should be used for 90% of the distance traveled. The tubing should be smooth
and have as few 90 degree bends as possible. Use tubing with a diameter that matches the
inlet of the exhaust blower. When with tubing is within 5 feet of the laser system, attach a
airflow gate, and then use a reducer to couple the tubing down to 2.5 inches (635 mm).
NEVER connect rigid tubing directly to the laser system. Use a short piece, 2 to 5 feet
(excessive length reduces airflow) of industrial grade wire reinforced rubber tubing, to
connect to the laser system. This will provide laser system mobility and will dampen
vibrations coming from the blower.
