What causes ultra-high temperature alarm (E05 or E07) on S&A Chiller due to excessive heat load?
If the S&A Chiller displays error code E05 or E07 indicating an ultra-high temperature alarm, and there is excessive heat load, reduce the heat load or use a model with a larger cooling capacity.
What to do for alarm E03 for ultra-high room temperature on S&A Chiller?
If the S&A Chiller displays error code E03 indicating an alarm for ultra-high room temperature, it means that the working ambient temperature is too high for the chiller. Improve ventilation to ensure the machine runs below 40 degrees Celsius.
Why is my S&A Chiller on but not electrified?
If the S&A Chiller turns on but is unelectrified, check and ensure that the power interface and the power plug are plugged in properly and have good contact.
How to fix unelectrified S&A Chiller if the fuse is burnt-out?
If the S&A Chiller turns on but is unelectrified, open the electric box cover and check the fuse. Replace it with a spare if necessary and ensure the power supply voltage is stable. Also, check that the power interface and plug are properly connected.
What to do if flow alarm (E01 or E02) occurs on S&A Chiller when running with other equipment?
If a flow alarm occurs (E01 or E02) on your S&A Chiller while running with other equipment, but there is water flowing and no alarm when using a water pipe directly connected to the chiller's water outlet and inlet, the water circulation pipes may be blocked or deformed. Check the water circulation pipes.
