7 4 Important Notice for Antifreeze to Avoid heat pump broken
Our heat pump has antifreeze function if the electricity is connected. So please keep the electricity always
connected even when you don t use the heat pumps
long time in winter or if the electricity is cut off by accident for more than 30 minutes, you need to drain out
all the recycling water to protect the heat pump to be freezen.
,
In cold area
for the safety, you d better use brine as the fluid in the heat pump water system instead of
pure water. If the lowest air temperature come to -10°C , you need add 25% C2H602 (Ethylene glycol) to the
clean pure water. If the lowest air temperature come to -25°C, you need to add 40% C2H602 to the clean
water.
7 5 Routine Maintenance
.
To prevent faults due to sediment in the heat exchangers, care must be taken to ensure that no impurities can
enter either the heat source system or the heating system. In the event that operating malfunctions due to
contamination occur nevertheless,the system should be checked.
.
1 Check and clean all the water filters every months
.
2 Check all the water pipe connection for any leakage every half year
.
3 Check the refrigerant pressure through the needle valve every year
