<1> INTRODUCTION
CW-3000 Series is professional cooling machine referring to international advanced
thermolysis cooling system design, suitable for small water-cooled cooling devices
requested machinery.
1. Specific disconnection alarm security protection.
2. Hermetic type water tank, water is available for a long time used.
3. Real-time temperature monitoring, accurate knowledge of heating devices working
condition.
4. Professional air-cooled forced radiator with strong heat dissipating capacity and difficult
to be blocked up.
5. Equipped with alarm output port to protect sensitive components quickly.
6. High cost performance, low failure rate.
7. There are several options of power supply, complete in specifications.
<2> CAUTION
1. It is strictly forbidden to plug and run the cooler without feeding water.
2. Cooler should be placed in a well-ventilated, dry environment place and away from heat
sources. Please keep at least 50cm from obstructions to the air outlet which is in the back
of the cooler, and should leave at least 30cm between obstructions and air inlets of two
sides.
3. The cooling water must be drained if the cooler is out of use for long time or before being
transported.
4. To protect laser tubes , the radiator fan of cooler will suspend to work when water
temperature is lower ( about 10℃) , and it will restart to run when water temperature rises
to higher ( about 20 ℃).

2. The first installation
It is very simple to install this industrial cooling machine. The first time installation of the
new machine can be carried out by following steps.
1. Open the package to check if the machine is intact and all the necessary accessories are
completed.
2. Open the injection port, then add cooling water.
3. According to system conditions, connect the water inlet and outlet pipe well.
4. Plug in power, turn on the power switch. (Do not allow the water overflow)
5. Check the water level of the water tank again. (It should be 80-150cm from the surface of
water to the injection port)

4. Maintenance
1. To ensure good heat dissipating, please open the lid to clean the dirt after the cooler used in
long-term.
2. Working in cold north area, it is better to use noncorrosive antifreeze fluid.
