How to replace the flow switch for the industrial water chiller?
First to turn off the laser chiller, unplug the power cord, uncap the water supply inlet, remove the upper sheet metal housing, find and disconnect the flow switch terminal, use a cross screwdriver to remove the 4 screws on the flow switch, take out the flow switch top cap and the internal impeller. For the new flow switch, use the same method to remove its top cap and impeller. then install the new impeller into the original flow switch. Use the cross screwdriver to tighten the 4 fixing screws, reconnect the wire terminal and you’re done~Follow me for more tips on chiller maintenance.

How to check the room temperature and flow of industrial water chiller?
Room temperature and flow are two factors that greatly affect the industrial chiller cooling capacity. Ultrahigh room temperature and ultralow flow will affect the chiller cooling capacity. The chiller works at room temperature above 40 ℃ for a long time will cause damage to the parts. So we need to observe these two parameters in real time.First, when the chiller is turned on, take the T-607 temperature controller as an example, press the right arrow button on the controller, and enter the status display menu. "T1" represents the temperature of the room temperature probe, when the room temperature is too high, the room temperature alarm will set off. Remember to clean up the dust to improve ambient ventilation. Continue to press the "►" button, "T2" represents the flow of the laser circuit. Press the button again, "T3" represents the flow of the optics circuit. When detected a traffic drop, the flow alarm will set off. It is time to replace the circulating water, and clean the filter screen.

How to replace the heater of the industrial chiller CW-5200?
The main function of the industrial chiller heater is to keep the water temperature constant and prevent cooling water from freezing. When the cooling water temperature is lower than the set one by 0.1℃, the heater starts to work. But when the heater of the laser chiller fails, do you know how to replace it?First, turn off the chiller, unplug its power cord, uncap the water supply inlet, remove the sheet metal casing, and find and unplug the heater terminal. Loosen the nut with a wrench and take out the heater. Take down its nut and rubber plug, and reinstall them on the new heater. Lastly, insert the heater back into the original place, tighten the nut and connect the heater wire to finish.

How to replace the cooling fan of the industrial chiller CW 3000?
How to replace the cooling fan for CW-3000 chiller?First, turn off the chiller and unplug its power cord, uncap the water supply inlet, unscrew the fixing screws and remove the sheet metal, cut off the cable tie, distinguish the cooling fan’s wire and unplug it. Take away fixing clips on both sides of the fan, disconnect the fan’s ground wire, untighten the fixing screws to take out the fan from the side. Watch carefully the airfow direction when installing a new fan, don't install it backwards because the wind is blowing out of the chiller. Assemble the parts back the way you disassemble them. It is better to organize wires using a zip cable tie. Lastly, assemble the sheet metal back to finish.What else do you want to know about the maintenance of the chiller? Welcome to leave a message to us.

Water temperature of laser remains high?
Try replacing the cooling fan capacitor of the industrial water chiller!First, remove the filter screen on both sides and the power box panel. Don't get it wrong, this is the compressor starting capacitance, which needs to be removed, and the hidden one inside is the starting capacitance of cooling fan. Open the trunking cover, follow capacitance wires then you can find the wiring part, use a screwdriver to unscrew the wiring terminal, the capacitance wire can be easily taken out. Then use a wrench to unscrew the fixing nut on the back of power box, after which you can take off the starting capacitance of the fan. Install the new one on the same position, and connect wire at the corresponding position in the junction box, tighten the screw and the installation is completed.Follow me for more tips on the chiller maintenance.

Replace The Filter Screen Of The Industrial Water Chiller
During the operation of the chiller, the filter screen will accumulate a lot of impurities. When impurities accumulated too much in the filter screen, it will easily lead to a chiller flow decrease and a flow alarm. So it needs to inspect regularly and replace the filter screen of the Y-type filter of the high and low temperature water outlet.Turn off the chiller firstly when replacing the filter screen, and use an adjustable wrench to unscrew the Y-type filter of the high-temperature outlet and the low-temperature outlet respectively. Remove the filter screen from the filter, check the filter screen, and you need to replace the filter screen if there are too many impurities in it. Notes not losing the rubber pad after replacing the filter net and putting it back in the filter. Tighten with an adjustable wrench.

Industrial water chiller CW 5200 dust removal and check water level
When using industrial chiller CW 5200, users should pay attention to cleaning the dust regularly and replacing the circulating water in time. Regular cleaning of dust can improve the chiller cooling efficiency, and timely replacement of the circulating water and keeping it at a suitable water level (within the green range) can prolong the chiller service life.First, press the button, open the dustproof plates on the left and right sides of the chiller, use an air gun to clean the dust accumulation area. The back of the chiller can check the water level, The circulating water should be controlled between red and yellow areas(within the green range).
