Note6.In case the temperature around the heat source unit has
possibility to drop under 0°C(32°F) or the inlet-water temp.
drops under 10°C(50°F), be careful for the following
point to prevent the pipe burst by the water pipe freeze-up.
•Add brine to water circuit.
•Circulate the water all the time even if the heat source
unit is not in operation.
•Drain the water from inside of the heat source unit when
the heat source unit will not operate for a long term.
