As the winter solstice approaches, temperatures continue to drop, and the cold is becoming increasingly intense. Once a central air conditioning system suffers freeze damage due to low temperatures, it may not only disrupt normal operation but also result in high repair costs. This MULTISTACK CARE Jiefeng Central Air Conditioning Antifreeze Guide serves as a “treasure trove” for safeguarding MULTISTACK equipment through the winter. Please save this guide for reference!

Key Antifreeze Precautions (for areas prone to freezing in northern regions)

1.Do not power off the system arbitrarily during cold weather
MULTISTACK Jiefeng central air conditioning units are equipped with antifreeze functionality. By keeping the unit powered on, it can automatically activate protective measures in low temperatures. Therefore, do not cut off the power during winter, and ensure that the water pump and the main unit are effectively interconnected.

2.Drain the system thoroughly during long-term shutdowns or power outages
If the air conditioning system will not be used during winter and requires a long-term shutdown or power outage, be sure to drain all water from the unit and pipelines, and keep the drain valve open.

3.Thoroughly inspect and clean the defrost drainage system
At the start of the heating season, carefully check and clean the outdoor unit’s defrost drainage outlets and pipelines. Ensure that the defrost drainage system is free from leaves, silt, or debris to prevent freezing in severe cold weather, which could affect the unit’s performance.

4.Add suitable antifreeze fluid as needed
In areas with unstable power supply or frequent unexpected power outages, consider adding an appropriate concentration of specialized antifreeze fluid to the water system. This helps avoid unnecessary losses caused by sudden incidents.
