I. Overview
This product is an industrial cooling device designed and manufactured for laser cutting,
laser welding, laser marking, laser engraving and other equipment that uses laser
processing. It can provide a temperature-stable cooling medium for the above application
scenarios.
The chiller is composed of a compressor, a condenser, a throttling device (expansion valve
or capillary), an evaporator, and a water pump. Its working principle is that the chiller’s
refrigeration system cools the water, and the water pump delivers the low-temperature
cooling water to the equipment that needs to be cooled. Then the cooling water will take
away the heat, heat up and return to the chiller, and then be cooled again and transported
back to the equipment. In the refrigeration system of a chiller, the refrigerant in the
evaporator coil absorbs the heat of the return water and vaporizes into steam. The
compressor continuously extracts the generated steam from the evaporator and
compresses it. The compressed high-temperature, high-pressure steam is sent to the
condenser and later will release heat (heat extracted by the fan) and condense into a high-
pressure liquid. After being reduced by the throttling device, it enters the evaporator to be
vaporized, absorbs the heat of the water, and the whole process circulates constantly.
Users can set or observe the working status of the water temperature through the
temperature controller.

IV. Installation
1. Open the package and check whether the machine is in good condition
and whether the accessories are complete.
2. Please ensure that the working voltage of the chiller is stable and
normal.
Because the refrigeration compressor is sensitive to the power supply voltage, the normal
working voltage of our company's standard products is 210~240V (110V model is
100~120V). If wider operating voltage range is necessary, customization is available.
3. Equipment installation conditions and requirements
(1) It must be installed on a horizontal surface and not tilted.
(2)The air outlet of the chiller should be at least 1.5m away from the obstacle, and the air
inlet must be at least 1m away from the obstacle (See below diagram).
(3) Do not install in harsh environments such as corrosive, flammable gas, dust, oil mist,
conductive dust, high temperature and humidity, strong magnetic field, direct sunlight, etc.
(4) Operating Environment

(5) Medium Requirements
Cooling medium allowed by the chiller includes purified water, distilled water, high-purity
water and other softened water. It is forbidden to use oily liquids, liquids containing solid
particles, corrosive liquids, etc. Clean the filter element and replace the cooling water
regularly (about three months is recommended) to ensure the normal operation of the
chiller.
When the chiller is stored with water at room temperature lower than 2℃, it is necessary
to add anti-freezer in the chiller water tank. It is recommended to use antifreeze with a
concentration of not more than 30% containing ethylene glycol or propylene glycol. After
the temperature warms up, change to purified water, distilled water or other suggested
cooling media, let the chiller run for 30 minutes to remove the residual anti-freezer and
drain it, and then refill with unused circulating water.
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

TY-JS-20319-003
10
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.

(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.

(2) Exhaust Air
After adding water for the first time or replacing water, exhaust the air in the water pump to
start use, otherwise the equipment will be damaged. The exhaust method is as follows：
Method 1: Under the state of shutting down, after adding water, remove the water outlet
and connect the water pipe, drain for 2 minutes, and then install it firmly.
Method 2：Open the water supply inlet, after starting the machine (water flows), repeatedly
press and fold the water pipe several times to drain the air from the pipe.
8.Test-run Check
(1) Check whether the pipeline connection is correct, and there must be no bubbling or
water leakage;
(2) Check whether the inlet and outlet water ball valves are open and the drain valve is
closed;
(3) Check the liquid level of the water tank;
(4) Confirm that the electrical wiring of the equipment is connected correctly;
(5) Confirm whether the equipment is grounded.

Case 1: Cooling water temperature is controlled by the intelligent control mode. The
required water temperature is from 25℃to 31℃and the set water temperature
is 3℃lower than the air temperature. Under the condition of constant air
temperature, the fluctuation should not exceed ±0.5℃. The alarm will be
triggered when the water temperature is 15℃lower or higher than the target
temperature (e.g., if the air temperature is 30.0℃, cooling water temperature is
between 27.5 ℃to 26.5 ℃, if the air temperature is up to 30.5 ℃, water
temperature will be between 28.0℃to 27.0℃).
Case 2: The cooling water temperature is controlled by the constant mode. It is required
that the water temperature is kept constant at 25℃, and the fluctuation should not
exceed ±2℃. The ultra-high temperature alarm will be triggered when the water
temperature is 5 ℃higher than the target temperature; and the ultra-low
temperature alarm will be triggered when the water temperature is 10 ℃lower
than the target temperature. The water temperature setting can be easily
adjusted from 5℃to 30 ℃by user setting.
