<1> Cautions
1. Please ensure that the power supply and electrical outlet are in good contact
and the earth wire must be firmly grounded!
The water chiller installation must be done by professional person in order to
avoid machine damage or accidents by misoperation.
2. Please make sure there is stable and normal voltage for the working chiller!
As the refrigeration compressor is more sensitive to the power supply and
voltage, so the operating voltage of our standard product is ±10 ％ of the
rated voltage. If you do need a wider operating voltage range, customization
is available for us.
3. Unmatched power frequency can cause the chiller damage!
Please choose model of 50Hz or 60Hz according to actual circumstance.
4. To protect the pump, it's strictly forbidden to run the chiller without water in
the storage water tank!
The new machine is packed after draining whole water in the tank, so please
make sure the tank has water inside before machine starting, otherwise it's
easily to have the pump damaged. When the water level is below the green
(NORMAL) range of the water level gauge, the cooling capacity of our chiller
will go down slightly. Hence please ensure the water level is within the green
(NORMAL) range. To drain through circulating pump is strictly prohibited!
5. Please be sure that the air inlet and air outlet are in good ventilation!
There must be at least 100cm from obstructions to the air outlet and at least
50cm between obstructions and the lateral air inlet.
6. Please pay attention to the effect of the condensate water!
With greater ambient humidity, when the water temperature is lower than the
ambient temperature, the condensate water will generate on the surface of
water circular pipes and the cooled components. If above circumstance
appears, it is recommended to set a higher water temperature or keep pipes
and cooled parts warm.
7. Please do turn on the chiller first before turn on the laser machine; turn off the
laser machine first before turn off the chiller.
8. This product is an industrial equipment. For professional use only!
