<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, 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 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 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 the model of 50Hz or 60Hz according to actual circumstances.
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 the whole water in the tank, so please make sure the tank has water inside before the machine starts, otherwise, it’s easy 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 a 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 30cm from obstructions to the air outlet which is in the back of the cooler and should leave at least 8cm 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 of 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. Professional use only! The appliance is not to be used by children or persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction, children are being supervised not to play with the appliance!

<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 the 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 the power, and turn on the power switch. (Do not start up without water in the water tank!) (1) Power switch is turned on, and the circulation pump of the chiller starts working.
The first time of operation 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 again 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-5000/5200 series uses an intelligent thermostat. Normally users do not need to adjust it. If it is really necessary, please refer to page 15, “Operating status and parameters adjustment.”
4

<4> Operation status and parameters adjustment
The new T503 intelligent temperature controller does not need to adjust the controlling parameters under normal circumstances. It will self-adjust controlling parameters according to room temperature for meeting equipment cooling requirements.
The new T504 intelligent temperature controller is selected constant temperature control mode as factory setting with the water temperature at 25 . Users can adjust it as needed.
T503 and T504 controllers are of the same functions and structure except for factory parameters setting.

(1) Case 1: cooling water temperature is controlled by intelligent mode. Requiring water temperature to be between 25 to 31. The 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 the water temperature is 10 lower or higher than the target. (e.g. when the ambient temperature is 30.0, cooling water temperature is between 27.5 to 26.5, if the ambient temperature is up to 30.5, the 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 at 28, and the fluctuation does not exceed ±2. The alarm of over high water temperature will be on when the water temperature is 5 higher than normal, and the alarm of over low water temperature will be on when the water temperature is 10 lower than normal.
(3) Case 3: cooling water temperature is controlled by constant mode. Requiring water temperature is constant at 25, and the fluctuation does not exceed ±1. The over-high water temperature will be on the water temperature is higher than 30, and the alarm of over low water temperature will be on when the water temperature is lower than 10 . (No matter what is the ambient temperature, the cooling water temperature is constant from 24.0 to 26.0)

<7> Simple troubleshooting

Failure
Machine turned on but unelectrified
Flow Alarm (panel red light is on)use a water pipe directly connect to the water outlet and inlet but still without
water flowing
Ultra-high temperature alarm
Alarm for ultra-high room temperature Serious problem of condensate water Water drains slowly from outfall during
water changing

Failure Cause Power cord is not plugged in place
Fuse burnt-out
Water level in the storage water tank is too low
Water circulation pipes are blocked or a pipe bending deformation.
Blocked dust gauze, bad thermolysis Poor ventilation for air outlet and inlet
Voltage is extremely low or astable Improper parameter settings on thermostat Switch the power frequently
Excessive heat load The working ambient temperature is too high for the chiller Water temperature is much lower than ambient temperature, with high humidity Injection port is not open

Approach Check and ensure the power interface and the power plug is plugged in place and in good
contact. Pull out the fuse box from the power supply interface of the chiller, check the fuse, replace with spare fuse if necessary and check whether the power supply voltage is stable; Check and ensure the power interface and the power plug is plugged in
place and in good contact. Check the water level gauge display, add water until the level shown in the green area; And check whether water circulation
pipe leaks.
Check water circulation pipe
Unpick and wash the dust gauze regularly
To ensure a smooth ventilation for air outlet and inlet
To improve the power supply circuit or use a voltage regulator To reset controlling parameters
or restore factory settings To ensure there is sufficient time
for refrigeration (more than 5 minuets) Reduce the heat load or use other model with larger cooling
capacity To improve the ventilation to guarantee that the machine is
running under 40. Increase water temperature or to preserve heat for pipeline
Open the injection port
