Thank you for using the machine from GUANGZHOU TEYU
ELECTROMECHANICAL CO., LTD. Please read the installation instructions
carefully before installing and operating and keep it properly.
This installation instructions is not a quality assurance. GUANGZHOU TEYU
ELECTROMECHANICAL CO., LTD reserves the right to the interpretation of
correction of typographical errors, improper mentioned information and product
improvement. The amended content will be reprinted in installation instructions
without notice in advance.
<1> Cautions
1. Please ensure that the power supply and electrical outlet are in good contact
and the earth wire must be firmly grounded!
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 of 200 ~ 250V (110V
model is of 100 ~130V). 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 50cm from obstructions to the air outlet which is in the
back of the cooler, and should leave at least 30cm between obstructions and
the side air inlet.
6. The filter screen must be regularly cleaned!
It’s essential to unpick and wash the dust gauze, or the serious blockage will
cause breakdown to the chiller.
7. 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.
8. This product is an industrial equipment.For professional use only.

<3> Installation
It is very simple to install this industrial cooling machine. The installation for the
first time of the new machine can be carried out by following steps:
1. Open the package to check if the machine is intact and all the necessary
accessories are completed.
2. Open the injection port to feed cooling water. (Do not let the water spill over!)
Observing the water level gauge and adding water slowly, be careful not to
have the water overflowed! For the cooling of carbon steel equipment, the
water should be added an appropriate amount of cooling water additive
(anti-corrosion water aqua). Working in cold north area, it’s better to use
noncorrosive antifreeze fluid.
3. According to system conditions, please connect the water inlet and outlet pipe
well.
4. Plug in power, turn on the power switch. (Do not start up without water in the
water tank!)
(1) Power switch turned on, the circulation pump of the chiller starts working. The
first time of operating may cause more bubbles in the pipe leading to a flow
alarming occasionally, but running for a few minutes later, it will go back to
normal.
(2) After the first boot, you must immediately check whether the water pipe leaks.
(3) Power switched on, if the water temperature is below the set value, it is normal
that fans and other components of the machine do not work. The temperature
controller will automatically control the working conditions of the compressor,
magnetic valve, fans and other parts based on the set controlling 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.
5. Check the water level in the water tank.
The first startup of the new chiller empties the air in the water pipe, leading a
slight water level decline, but in order to keep the water level in the green area,
it’s allowed to add adequate water again. Please observe and record the current
water level, and inspect it again after the chiller running for a period of time, if
the water level drops obviously, please re-inspect the water pipeline leakage.
6. Adjust parameters of temperature controller.
CW-6000/ 6100/ 6200 series use an intelligent thermostat. Normally users do not
need to adjust it. If it is really necessary, please refer to page 17, “Operating
status and parameters adjustment.”

The new T-506 intelligent temperature controller does not need to adjust
the controlling parameters under normal circumstance. It will self-adjust
controlling parameters according to room temperature for meeting equipment
cooling requirements.
The new T-506H intelligent temperature controller is selected constant
temperature control mode as factory setting with water temperature at 25℃.
User can adjust it as needed.
T-506 and T-506H controllers are of same functions and structure except
default setting.

7. Advanced parameters adjustment case:
(1) Case 1: cooling water temperature is controlled by intelligent mode. Requiring
water temperature to be between 25℃to 31℃. Ambient temperature keeping
constant, when the set water temperature is 3℃lower than the ambient, the
fluctuation will not exceed ±0.5 ℃. There will be an alert when water
temperature is 10 ℃lower or higher than target. (e.g. when ambient
temperature is 30.0℃, cooling water temperature is between 27.5℃to 26.5℃,
if ambient temperature is up to 30.5 ℃, water temperature will be between
28.0℃to 27.0℃.)
(2) Case 2: cooling water temperature is controlled by constant mode. Requiring
water temperature is constant in 28℃, and the fluctuate does not exceed ±2℃.
The alarm of over high water temperature will be on when water temperature is
5℃higher than normal, and the alarm of over low water temperature will be on
when water temperature is 10℃lower than normal.
(3) Case 3: cooling water temperature is controlled by constant mode. Requiring
water temperature is constant in 25℃, and the fluctuate does not exceed ±1℃.
The over high water temperature will be on then water temperature is higher
than 30℃, and the alarm of over low water temperature will be on when water
temperature is lower than 10 ℃. (No matter what is the ambient temperature,
the cooling water temperature is constant in 24.0℃to 26.0℃)
