Thank you for using the machine from GUANGZHOU TEYU
ELECTROMECHANICAL CO., LTD. Please read the User Manual carefully before use
and keep it properly.
This User Manual is not a quality warranty book. GUANGZHOU TEYU
ELECTROMECHANICAL CO., LTD reserves the rights to the interpretation of any
correction of typographical errors, improper mentioned information and product
improvement. The amended content will be printed in reprint edition of User Manual
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!
Although the average operating current of the chiller is small, but the
instantaneous operating current could be up to 6 ~ 10amps sometimes (The
instantaneous operating current of models of AC110V power supply are
possible to be up to 10 ~ 15amps).
2. Please make sure the chiller’s working voltage is stable and standard.
As the refrigerate compressor is more sensitive to voltage of power supply, the
standard working voltage of our standard machines is 210~240V (110V model is
100~120V).
3. Unmatched frequency of power supplies can leading to chiller damage !
Choose 50Hz or 60Hz model according to actual circumstance.
4. In order to protect the water pump, it is strictly forbidden to run the chiller
without water in water tank
The new machine will empty all water in water tank before packing in the box,
so make sure the water tank is filled with water before starts the machine or the
water pump will damage easily. When water gauge of water tank below green
NORMAL area, the refrigeration volume will drops a little, please make sure the
water gauge is around the green NORMAL area. To drain through circulating
pump is strictly prohibited.
5. Please be sure that the air inlet and air outlet are in good ventilation!
The air outlet that is at the back of the chiller at least 30cm away from
obstructions, and 8cm for the side air inlet.
6. The filter of air inlet requires cleaning regularly.
It is important to wash the anti-dust gauze regularly by removed it from chiller,
because if anti-dust gauze heavy accumulated dust will lead to chiller failure.
7. Please pay attention to condensate water.
When water temperature lower than ambient temperature, and ambient
humidity is higher, the condensate water will generate on the surface of circular
water pipes and surface of devices which being cooled. If it happens, setting
higher water temperature or keep warm for water pipes and devices will be
recommended.
8. The machine is industrial equipment, only professional people allowed to use.

<3> Installation
The chiller is designed for Ultraviolet Laser, it is easy to install and use. Please
follow below steps for the first time use of new chiller.
1. Open the package to check if the machine is intact and all the necessary
accessories are completed.
2. Open the injection port and pour cooling water.Observing the water level gauge
while pouring water, please do it slowly do not overflow. For cold area at north
China, should add noncorrosive antifreeze fluid.
3. Well connect the water inlet and outlet pipes according to apply equipments.
4. Plug in power, turn on the power switch. (Do not turn on the machine without
water in the water tank!)
（1）The circulation pump is starting work after the power switch turned on. The
first time of operating may cause more bubbles in the pipe leading to flow
alarming occasionally, but keep it running for a few minutes later, it will back
to normal later.
（2）For the first boot, will required immediate attention to check whether the water
pipe leaks.
（3）It is normal the fan and other components of machine not works if water
temperature lower than set water after started the machine. The temperature
controller will automatically control the working status of compressor,
magnetic valve and fan etc components upon the set parameters.
（4）As it takes time for the compressor etc components to start, the waiting period
could range from tens second to few minutes according to different working
condition before the machine start, so do not turn on and off the chiller
frequently.
5. Check the water level of water tank
The water level in water tank will drop slightly as the air in water pipe was
empty after new machine turned on. It is ok to refill certain amount of water in
order to keep the water level around green area. Observe and record current
water level, check the water level again after chiller running for a period of time,
if water level drops obviously, will require to check whether the water pipeline
leaks.
6. Parameters of temperature controller adjustment
Default setting of CWUL-05/10/20 series UV laser chiller temperature controller
is 25℃water temperature cooling UV parameter, usually do not need to adjust
the control parameter ,but if special require for specific temperature ,please
refer P6 of 《Operation and Parameters adjustment》

5、Advanced settings adjustment
（1）Press and hold the ”button while press SET button for 5 seconds until 00
displayed in upper window and PAS in lower window. Then press keys to
select the password (default setting is 8), and then press the SET button, if
the password is correct, F0 displays, entering into setting status, means the
temperature controller is under parameter setting status. If the password is
incorrect, it returns to temperature display. To avoid operation mistake,
passwords could change by equipment user or equipment keeper.
（2）Enter setting status, press buttons to modify parameter content
follow by recycle,then press “ ”buttons to modify the parameter
values. Press confirm button RST at any time to exit parameters setting with
saving modified parameters and return to temperature display, then chiller
runs under the new parameters. If there is no any action within 20 seconds,
the controller will automatically exit parameters setting without saving the
modified parameters (under parameters setting status, system running in
original parameters). Under parameters setting status, SET key does not
work.
Note:
1. During parameters setting status, system runs under original parameters.
2.Under constant temperature control mode, the water temperature is
controlled by parameter F0.
3. Under intelligent control mode, the water temperature will be automatically
adjusted according
to ambient temperature changes. The temperature difference is controlled
by F1.
6. Advanced parameters adjustment cases：
（1）Case 1：26.8 ℃cooling UV laser settings
Chiller under constant temperature control mode, press SET button will
display setting water temperature value（F0）,then press or
buttons to modify setting temperature value, set the temperature to
26.8 ℃,press RST button save parameter and exist then back to the
temperature display (If there is no any action within 20 seconds, the
controller will automatically exit parameters setting return to temperature
display without saving the modified parameters)
（2）Case 2：16℃cooling UV laser settings
Chiller under constant temperature control mode, press SET button will
display setting water temperature value（F0）,then press or
buttons to modify setting temperature value, set the temperature to
16.0 ℃,press RST button save parameter and exist then back to the
temperature display (If there is no any action within 20 seconds, the
controller will automatically exit parameters setting return to temperature
display without saving the modified parameters)
（3）Case 3：Change alarm temperature of water temperature ,water temperature
higher 5 ℃than set value will alarm ,lower 10 ℃than set value will alarm.
Press and hold button while press SET button lasts 5 seconds the
temperature controller will display 0, then press button modifies 0 to
8(default setting password),and then press SET button will enter setting
content code display turns to F0 if password corrects (Will restore to actual
water temperature if password incorrect). Press or button
