free of impurities, so as to prevent impurities from entering the waterway
and causing blockage or pump failure.
5. Plug in the power cord and turn on the power switch (it is forbidden to
start without water).
(1) After turning on the power switch, the circulating pump of the chiller starts to work.
When the new machine is turned on for the first time, there will be more air bubbles in the
pipeline, which will cause the machine to alarm occasionally, and it will return to normal
after a few minutes of operation.
(2) After starting the machine for the first time, check if the water pipes leak immediately.
(3) After turning on the power, if the water temperature is lower than the set temperature, it
is normal that the cooling fan and other devices of the machine do not work. The
temperature controller will automatically control the working status of compressors,
solenoid valves, cooling fans and other components according to the set parameters.
6.Electrical connection
(1) Please select the cable based on the max. rated current indicated on the label of the
chiller.
(2) Recommended reference standard for power cord diameter selection.
Rated current/ A
Wire diameter (copper wire)/ mm²
Note: This data is provided according to IEC 60204-1 standard and only forreference.
Standard cables must be used in the power cord.
(3) The main circuit of the power supply must be equipped with appropriate electric leakage
and overload protection devices, and the chiller must be well grounded.
(4) Less than ±10% of power supply voltage fluctuation and less than ±1Hz of frequency
fluctuation are allowed, and keep away from electromagnetic interference sources.
7. Fill Water & Exhaust Air
(1) Fill Water
After the new machine is turned on, the air in the water pipe is emptied, and the water level
of the water tank will drop slightly. In order to keep the water level in the green area, you
can add water again. Observe and write down the current water level. After the chiller has
been running for a period of time, observe the water level gauge again. If the water level
drops significantly, check again if there is leakage in the water pipes.
