4. Determine the direction of the pipeline layout according to the water
inlet and outlet of the chiller, and ensure that the waterway is clean and
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 leaks 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.
(4) As it takes a longer time to start over the compressor and other components, according
to different conditions, the time is range from seconds to minutes, so do not turn off the
power and again on frequently.
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.

Note: This data is provided according to IEC 60204-1 standard and only for
reference. 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.
