How to resolve ultrahigh room temperature alarm on S&A Chiller?
If the S&A Chiller shows an ultrahigh room temperature alarm, it indicates that the room temperature is too high for the chiller to operate correctly. Improve the ventilation to ensure the machine runs below a 40° room temperature.
Why does water drain slowly from S&A Industrial Equipment during water changing?
If water drains slowly from the outfall during water changing in your S&A Industrial Equipment, it may be because the injection port is not open. Open the injection port to allow the water to drain properly.
Why is there a serious problem of condensate water in my S&A Industrial Equipment?
If you're experiencing a serious problem with condensate water in your S&A Industrial Equipment, it's likely because the water temperature is much lower than the ambient temperature, and humidity is high. Try increasing the water temperature or insulating the pipeline to preserve heat.
Why S&A Industrial Equipment has flow alarm (E6) with other equipment but not with direct water connection?
If your S&A Industrial Equipment triggers a flow alarm (E6) while running with other equipment, but works fine with a direct water pipe connection, the water circulation pipes may be blocked or deformed due to bending. Inspect the water circulation pipe to resolve this issue.
What to do if S&A Industrial Equipment shows flow alarm (E6) despite direct water connection?
If your S&A Industrial Equipment experiences a flow alarm (E6) even when using a water pipe directly connected to the water outlet and inlet, it indicates that the water level in the storage water tank might be too low. Check the water level gauge display and add water until the level is within the green area. Also, inspect the water circulation pipes for any leaks.
What to do if S&A Industrial Equipment shows alarm for ultra-high room temperature (E1)?
If your S&A Industrial Equipment displays an ultra-high room temperature alarm (E1), it means the working ambient temperature is too high for the chiller. To resolve this, improve ventilation to ensure the machine operates below 40 degrees Celsius.
How to fix S&A Industrial Equipment that turns on but is unelectrified?
If your S&A Industrial Equipment turns on but is unelectrified, there are a couple of things to check. First, make sure the power cord is properly plugged into the power interface and that the connection is secure. Also, check the fuse. If it's burnt out, open the electric box cover, inspect the protective tube, and replace the fuse with a spare if needed. Ensure the power supply voltage is stable and the power interface and plug are making good contact.
Why does my S&A Industrial Equipment show an ultra-high temperature alarm (E2)?
An ultra-high temperature alarm (E2) on your S&A Industrial Equipment can be triggered by several factors. First, check if the dust gauze is blocked and needs cleaning to improve thermolysis. Poor ventilation around the air outlet and inlet can also cause this, so ensure they are unobstructed. Other potential causes include extremely low or unstable voltage (in which case, improve the power supply circuit or use a voltage regulator), improper thermostat parameter settings (reset controlling parameters or restore factory settings), frequent power switching (ensure at least 5 minutes between power cycles for refrigeration), and excessive heat load (reduce the heat load or switch to a model with larger cooling capacity).
Why is there a serious condensate water problem with my S&A CWFL-1500 Chiller?
If you have a serious condensate water problem with your S&A Chiller, it could be because the water temperature is much lower than the ambient temperature, combined with high humidity. Increase the water temperature or insulate the pipeline to preserve heat.
How to fix S&A CWFL-1500 Chiller ultrahigh water temperature alarm (E2)?
If your S&A Chiller displays an E2 error, indicating an ultrahigh water temperature alarm, several factors could be responsible. First, the dust gauze might be blocked, hindering thermolysis, so disassemble and clean it regularly. Ensure proper ventilation around the air outlet and inlet. Unstable or extremely low voltage can also trigger this alarm, so improve the power supply circuit or use a voltage regulator. Resetting the thermostat parameters or restoring factory settings might help if the settings are improper. Allow sufficient time (more than 5 minutes) for refrigeration between power cycles. Finally, excessive heat load can cause this issue; reduce the heat load or consider a model with larger cooling capacity.

This document is the user manual for the CWFL-500/1000/1500/2000/3000 Industrial Chiller, identified by document number TY-JS-211220-009. It provides comprehensive information for the safe and effective operation, installation, and maintenance of the chiller.
The industrial chiller is a cooling device specifically designed for laser processing equipment, including laser cutting, welding, marking, and engraving machines. Its primary function is to provide a temperature-stable cooling medium to these applications. The chiller operates on a refrigeration cycle, consisting of a compressor, condenser, throttling device (expansion valve or capillary), evaporator, and a water pump. The refrigeration system cools water, which is then circulated by the water pump to the laser equipment. This cooling water absorbs heat from the equipment, heats up, and returns to the chiller to be re-cooled. Within the refrigeration system, refrigerant in the evaporator coils absorbs heat from the return water and vaporizes into steam. The compressor then extracts and compresses this steam, sending the high-temperature, high-pressure steam to the condenser. The condenser releases heat (aided by a fan) and condenses the steam into a high-pressure liquid. This liquid then passes through a throttling device, reducing its pressure, before entering the evaporator to vaporize again, absorbing more heat from the water. This continuous cycle ensures a stable cooling medium for the laser equipment. Users can monitor and adjust the water temperature and working status via the temperature controller.
The manual outlines several critical specifications and requirements for the chiller's operation:
