This is the original instruction, please read all manual instructions carefully before operating. VEVOR reserves a clear interpretation of our user manual. The appearance of the product shall be subject to the product you received. Please forgive us that we won’t inform you again if there are any technology or software updates on our product.

Warning- To reduce the risk of injury, the user must read the instructions manual carefully.

WARN

1. PLEASE MAKE SURE THAT THE POWER SUPPLY AND THE POWER OUTLET ARE IN GOOD CONTACT AND THE GROUNDING WIRE MUST BE FIRM!
   Although the average working current of the chiller is small, the instantaneous working current can sometimes reach 6~10 amperes (the instantaneous working current of the AC110V power supply model is possible up to 10~1 5 amperes)

2. PLEASE MAKE SURE THAT THE WORKING CHILLER HAS A STABLE AND NORMAL VOLTAGE!
   Since the refrigeration compressor is more sensitive to the power supply and voltage, so the working voltage our standard product is 220^ 240V (the 110V model is 110 120V), if you need a wider operating voltage range, we can customize it.

3. PLEASE MISMATCHED POWER FREQUENCY WILL CAUSE CHILLER DAMAGE!
   Please select mode: 50Hz or 60Hz depending on the actual situation.

4. TO PROTECT THE PUMP, IT IS STRICTLY FORBIDDEN TO RUN THE CHILLER WITHOUT WATER IN THE STORAGE TANK!
   The new machine is packed after draining the entire water in the tank, so please make sure that the tank has enough water and there is water inside the machine before starting, otherwise it is easy to damage the pump.
   When the water level is below the green (normal) range of the water level gauge, the cooling capacity of our chillers will drop slightly. Therefore, make sure that the water level is in the green (normal) range. Pumps are strictly forbidden by circulating drainage!

5. PLEASE MAKE SURE THE AIR INLET AND OUTLET ARE WELL-VENTILATED!
   The air outlet from the obstacle to the back of the cooler must be at least 30 cm, and it should be at least 8 cm between the obstacle and the side air intake.

6. THE FILTER MUST BE CLEANED REGULARLY!
   The dust meter must be unlocked and cleaned, otherwise it will cause serious clogging failure to the cooler.

7. PAY ATTENTION TO THE EFFECT OF CONDENSATE!
   As the ambient humidity increases, when the water temperature is lower than the ambient temperature, condensate will create circular pipes and cooling parts on the water surface. If this occurs, it is recommended to set a higher water temperature or keep the connected pipes and cooling components warm.

PROFESSIONAL USE ONLY

• This device must not be used by a child or a person with physical, sensory or physical, sensory, or physical impairments, or lack of experience and knowledge, unless supervision or instruction is given, and the child is not allowed to play with electrical appliances!
• The circulating water of the water cooler must use a sealed container for normal use, such as laser tube cooling water. Unsealed containers cannot circulate, such as water basins, and buckets cannot be used for circulating water cooling with water coolers.

PROCEDURE

• Installing this industrial chiller is very simple.
• The first installation of a new machine can be carried out by following these

steps:

1. OPEN THE PACKAGE TO CHECK IF THE MACHINE IS FIXED AND ALL NECESSARY ACCESSORIES ARE COMPLETE.

2. OPEN THE WATER SUPPLY INLET TO SUPPLY COOLING WATER (DON’T SPILL THE WATER OUT!).
   Observe the water level gauge and add water slowly, taking care not to let the water overflow! For the cooling of carbon steel equipment, an appropriate amount of cooling water additive (anti-corrosion water aqua) should be added to the water. Users in cold regions should use non-corrosive antifreeze.

3. CONNECT THE INLET AND OUTLET PIPES ACCORDING TO THE SYSTEM CONDITIONS.

4. PLUG IN THE POWER SUPPLY AND TURN ON THE POWER SWITCH. (DON’T START WITHOUT WATER IN THE TANK!)

5. The power switch is turned on and the circulating pump of the chiller starts to work. The first operation may cause more bubbles in the pipe, causing occasional alarms for traffic, but after a few minutes of operation, it will return to normal.

6. After the first start-up, the water pipe must be checked for leakage immediately.

7. The power supply is turned on, if the water temperature is lower than the set value, it is normal that the fan and other parts of the machine do not work. The temperature controller will automatically control the working state of compressor solenoid valves, fans and other components according to the set control parameters.

8. Since the restart of the compressor and other components takes a long time, depending on different conditions, the time varies from a few seconds to a few minutes, so do not turn off the power frequently and turn it on again.

9. CHECK THE WATER LEVEL IN THE TANK. The first start of the new cooler drains the air in the water pipe, causing a slight drop in the water level, but in order to maintain the water level in the green area, it is allowed to add enough water again. Please observe and record the current water level, check again after the chiller has been running for a period of time, and if the water level drops significantly, please re-check the leakage of the water pipe.

10. ADJUST THE TEMPERATURE CONTROLLER PARAMETERS.
    CW-5000/5200 series uses intelligent thermostats. Usually, the user does not need to adjust it. If it is really necessary. See “Operating status and parameter tuning”.

PARAMETER ADJUSTMENT

• The new T503 intelligent temperature controller requires no regulation control. Parameters under normal conditions.
• The control parameters can be adjusted according to the room temperature to meet the heat dissipation requirements of the equipment. The new T504 intelligent temperature control selects the constant temperature control mode as the factory setting, and the water temperature is 25°C, which can be adjusted by the user as needed.
• The functions and structure of the T503 and T504 controllers are the same, except for factory parameter settings.

Traffic 1 alarm

| When A9=0, flow 1 enters to start the alarm when flow < F10 (flow 1 alarm value) is detected, and exit the alarm when flow > F10 (flow 1 alarm value); When A9=1,the flow 1 input switch is alarmed when it is open, and the exit alarm is

exited when the switch is turned on

E7

| ****

Traffic 2 alarm

| When A11=0, the flow 2 input starts the alarm when flow < F11 (flow 2 alarm value) is detected, and the alarm is exited when flow > F11 (flow 2 alarm value).

When A11=1, the alarm is activated when the flow 2 input switch is open, and the alarm is exited when the switch is

turned on

Concentrate:

1. E2 alarm is effective only after meeting the start-up alarm delay (A1) or entering the target temperature section (that is, between the set temperature and the set temperature + refrigeration return difference F2) after the thermostat is powered on
2. E3 alarm is effective only after meeting the start-up alarm delay (A1) and after the thermostat is powered on, the water temperature enters the target temperature section (that is, between the set temperature and the set temperature + refrigeration return difference F2).
3. When the power on alarm delay A1 is set to 0,the E2 water temperature ultra-high alarm will be triggered immediately when the water temperature is super high when the power is turned on; When the power on water temperature is ultra-low, the E3 water temperature ultra-low alarm is triggered immediately

Relay output status when alarming:

1. When E1, E2, E3 alarm, the compressor and refrigerant solenoid valve are controlled according to the normal control logic.
2. The water temperature setting (F0) of the controller when E4 alarm runs according to the factory setting. When operating in constant temperature mode, there is no E4 alarm.
3. When E5 alarms, the system automatically switches to the refrigeration state.
