The following are types of water chillers:
Water chiller with cooling fan (CW3000)
Water chiller with gas compressor (CW5200, CW5000)
Standard temperature setting for our Co2 laser tubes is 22-24 degrees celsius. The temperature must not rise above 35 degrees celsius for operating.
Alarm:
The alarm is triggered when there is no water circulation and has nothing to do with water temperature.
Solution
To solve your problem, switch on water chiller, check inlet and outlet pipes for water circulation.
Check both pipes from the chiller to your laser tube. The pipes could be bent or constricted or there could be objects on the pipe blocking the water circulation.
The following could solve your problem...
If there is no circulation, switch off and disconnect the pipes. Use a shorter pipe to connect both ends to the chiller, preferably a clear pipe. One at the inlet and outlet of the chiller. Check for water circulation.
If water is circulating, test the alarm by pressing the pipe thus blocking the water circulation which should sound the alarm.
If the water is circulating, it could also be that the water flow switch is faulty. The switch is on the inside of the chiller behind the water outlet. The switch would need to be replaced.
However, if you are sure the water is circulating, shorten the inlet and outlet connector pipes/tubes to the shortest possible length. If they are too long, the pump in the chiller may not be able to pump as strongly and registers as no water circulating. The alarm will be triggered even though the water is circulating.
We don't suggest you disconnect the alarm siren.
If this does not solve your problem and your machine is under warranty...
Stop investigation immediately, pack in original box and send it back for us to repair.
Additional tips for troubleshooting:
Firstly, follow water chiller maintenance. When you open the chiller, you will see a small black cylinder and pump.
This pump cannot break so you can loosen the screws and check inside.
There is a small magnet inside, clean the pump with an earbud and close. Sometimes there is a small stone or dust inside this pump.
Lastly, the alarm only warns you that there is no water circulation. It has nothing to do with the temperature.
