4. During its first use, press

to speed the activation of the compressor.
5. Once the chiller is fully operational, its cooling liquid should begin to run through your machine
and back into your tank. Pay attention to the following:
•
ALWAYS obtain visual confirmation that the liquid is flowing through the laser tube behind
the top rear access door before starting your laser.
•
Check that the water level remains in the NORMAL area of the gauge after filling the cooling
pathway for your engraver. If it has fallen to the ALARM level, check for any leaks and then
add more distilled water or laser-safe antifreeze as necessary.
•
There may be alarms from the chiller or engraver when the chiller first begins operation. This
is because of air bubbles being cleared from the line, which in normal use would pose a risk
of overheating the laser tube. The bubbles should dissipate and the alarms should cease
after a few minutes of operation. If any other alarms occur, see the Troubleshooting section
for the meaning of the specific error code.
•
NEVER allow the liquid in the tank to become too hot to cool the laser. If you have
deactivated the chiller’s automated alarms, periodically check the liquid’s actual temperature
during prolonged use. If the liquid ever begins to approach 100
℉
(38
℃
), operate the laser
at a lower power setting or pause its activity to allow time for the chiller to further cool the
machine. When the water temperature exceeds a certain range of the set temperature, the
chiller will sound an alarm. In the alarm state, the laser tube stops emitting the laser beam.
•
Your chiller includes a small amount of R-410A refrigerant. This should never present a hazard
or need replacement but, if you ever notice the chiller struggling to cool your machine during
normal operation, stop the use of the machine, make sure the area is well-ventilated, and
have a trained and skilled professional contact Customer Service for instructions on how
to check the refrigerant level, safely repair any leaks, and add additional refrigerant before
further use.
NEVER attempt to adjust the refrigerant yourself without professional
training.
6. Flip off the power switch and circuit breaker, and disconnect the power cord after checking,
setting, or each use.
