Product Package:

• To ensure good heat dissipating, please open the lid to clean the dirt after the cooler used in long-term.
• Users in cold area should use noncorrosive antifreeze fluid.

• Ensure that there is good contact between the chiller plug and power socket. Furthermore, ensure that the chiller is correctly earthed!
• The normal working voltage of the standard model is 210V-240V (110MODEL IS 100V-120V). Ensure that the working voltage of the chiller is stable and normal
• Use the model of 50Hz or 60Hz according to the actual situation. Improper power frequency matching will damage the chiller!
• To protect the water pump, it is strictly forbidden to run the chiller without water!
• The air outlet of the chiller must be kept at least 50cm from the obstacle and the air inlet must be kept at least 30cm from the obstacle!
• The cooling water must be drained if the cooler is out of use for long time or before being transported.
• 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℃).
• This product is industrial equipment and must only be carried out by suitably qualified personnel.

Flow alarm output ports and the wiring diagram:

In order to guarantee the equipment will not be damaged while cooling water circulation is out of control, CW-3000 series water cooler possess a low folw alarm protection.

Note: The folw alarm is connected to the normally open relay and normally closed relay contacts, requiring operating current less than 5A, working voltage less than 300V.

• Open the package to check if the chiller is intact and all the necessary accessories are completed.
• Unscrew the water supply inlet and add cooling water (do not spill out the water).
• Connect the water inlet and outlet pipes well according to system conditions.
• Connect the power cord and turn on the power switch.
• Check water level in the water tank, it should be 80-150mm from the surface of water the injection port.
