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
If you don t want to use the heat pumps for
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.
