Product Usage Instructions:

1. Fill the water tank with distilled or deionized water. If
   cooling carbon steel equipment, add the appropriate amount of
   anticorrosive additive. Do not fill the tank completely. Pay
   attention to the water gauge and ensure that the water level is at
   the appropriate level, between the middle and top of the green
   area. Pour slowly to avoid overflowing.
2. Connect the chiller’s water outlet port to the water inlet of
   the product to be cooled, and connect the chiller’s water inlet
   port to the water outlet of the product to be cooled.
3. Plug in the power cable and turn on the water chiller. The pump
   will start working, and any initial bubbles should disappear after
   a minute or two. Note that the fans and other components of the
   chiller may not activate immediately as they are automatically
   controlled and will only start working when needed by the
   machine.
4. Adjust the water chiller’s parameters using the control panel
   as needed.

Temperature Adjustment:

To adjust the water temperature:

1. Press the SET button to enter settings mode.
2. Use the and buttons to modify the desired water
   temperature.
3. Press the RST button to save and exit.
4. Press the SET button to exit without saving. If there is no
   activity for 20 seconds, settings mode will also exit without
   saving. The set temperature will be displayed on the lower readout,
   and the chiller will gradually bring the actual water temperature
   to that level over time.

Password Protection:

To set a password for advanced settings:

1. Press and hold the SET button until “00” is displayed in the
   Actual Temp display and “PAS” is displayed in the Set Temp
   display.
2. Use the and buttons to select your desired password.
3. Press the SET button to save and exit.

Parameter Adjustment:

To adjust parameters in advanced settings:

1. Enter your password again.
2. The device will enter the advanced settings mode.
3. Use the and buttons to cycle through the parameters.
4. Use the and buttons to modify the current parameter.
5. Press the RST button to save and exit.
6. Press the SET button or wait to exit without saving any
   changes.

Safety Information
Warning!
· DO NOT use this product with an incompatible, unstable, or ungrounded power supply. Only use with well-grounded 3-prong 110V/60Hz outlets. Do not use a 3 to 2-prong adapter to allow it to run from an ungrounded outlet.
· DO NOT run this chiller without first filling it with an adequate amount of distilled water or specially formulated laser-safe antifreeze. If neither is available, deionized water is preferable to tap water, which can cause faster scaling and microbial growth that will shorten the life expectancy of your chiller and attached devices.
· Place this chiller in a dry well-ventilated environment away from heat sources but warm enough to avoid freezing temperatures.
· Ensure at least 1 ft. (30 cm) of open space next to its side air inlets. · Ensure at least 18 (50 cm) of open space above its top air outlet. · When cooling a laser engraver, take care that this device does not cause the room’s humidity
to exceed safe levels. Some smaller rooms may require additional ventilation to ensure safe engraving.
Caution!
· Remember that the OUTLET of the water chiller should connect to the INLET of the product to be cooled. Similarly, the water chiller’s inlet should be connected to the other machine’s water outlet.

Installation
1. Fill the water tank with distilled or deionized water. For cooling carbon steel equipment, include the appropriate amount of anticorrosive additive. DO NOT fill completely. Pay attention to the water gauge and ensure that the water level at the appropriate level. Use the water level gauge and ensure the level is between the middle and top of the green area. “FULL” is actually overfull. Pour slowly and do not allow the water to overflow.
2. Connect the chiller’s water outlet port to the water inlet of the product to be cooled and connect the chiller’s water inlet port to the water outlet of the product to be cooled.
3. Plug in the power cable and turn on the water chiller. The pump will begin working. There may be some bubbles at first. These should disappear after a minute or two. Don’t worry if the fans and other components of the chiller do not activate. They are usually automatically controlled and will not begin working until they are needed by the machine.
4. Check the water level of the tank again using the water level gauge. The water level of the chiller may be lowered as it fills the cooling path in your device. If necessary, carefully add more water to the chiller to maintain appropriate levels of water. Keep the level between the middle and top of the green area. If the water level drops sharply or continues to go down during normal use, turn off your device and examine the water pipes and cooling path for leakage. Repair any such leaks before restarting the devices and continuing work.
5. Adjust the water chiller’s parameters with the control panel as needed.

Case 1: The chiller is in intelligent control mode and requires the water to be between 77­88°F (25­31°C). With the ambient room temperature kept constant, the water temperature will remain 5°F (3°C) lower with a deviation of ±0.9°F (±0.5°C). An alarm will sound if the water temperature is 18°F (10°C) higher or lower than this target.
Case 2: The chiller is in constant temperature mode and requires the water to be at 82°F (28°C) with a deviation of ±3.6°F (±2°C). An alarm will sound if the water temperature is 9.6°F (5°C) higher than this target or if the water is 18°F (10°C) lower than this target.
Case 3: The chiller is in constant temperature mode and requires the water to be at 77°F (25°C) with a deviation of ±1.8°F (±1°C). An alarm will sound if the water temperature goes above 86°F (30°C) or below 50°F (10°C).

Restore Factory Settings
While the chiller is in standby mode, press and hold and until “rE” is displayed. All settings have now been returned to factory defaults.

Maintenance
· Regularly clean the air filter of dust and debris with a soft cloth or vacuum. · Periodically clean the inside of the inlet and outlet hoses to ensure no clogs form. To do this,
soak the hoses in a mild detergent solution with a low concentration of biocide (e.g. bleach) for 8­24 hours. Rinse the hoses with tap water before reinstalling them. · Periodically clean the water tank with a mild detergent solution with a low concentration of biocide (e.g. bleach) to prevent and remove scaling. · Disconnect the chiller from its power supply and drain all water before transporting it or placing it in storage.

Troubleshooting

Potential Problems The chiller does not turn on. Condensation forms on the chiller. Water drainage is slow. Scaling builds up in the water tank.

Usual Solution(s)
Check your electrical connections, fuse box, and circuit breaker.
Increase chilling temperature or decrease the ambient room temperature.
Open the water tank inlet to allow air to flow more freely.
Clean with a mixture of water, mild detergent, and bleach.

Error Messages
