* Connect the heat source piping in reverse if the inlet temperature of heat source fluid is 27 °C or more.
(heat source fluid inlet is lower side, outlet is upper side) Install the attached label as shown below if the heat source fluid is
connected in reverse.
To protect the heat exchanger from corrosion, the makeup
water and the circulating water need to meet the Water Quality
Standards below.
