CAUTION: In order to reduce the operation cost, the hot water outlet pipes should be
properly insulated. If the water heater is subjected to freezing temperature that is less than
0 ć , the cold water inlet pipes should also be insulated.
CAUTION: In order to reduce the operation cost, please select PP-R tube with good
insulation performance. According to water temperature, working pressure, tube life and
the equivalent, the wall thickness of PP-R pipes is rated for the following six series by
pressure, PN1.0, PN1.25, PN1.6, PN2.0, PN2.5 and PN3.2. For hot water pipe and
fittings, the minimum pressure rating is PN2.0; for cold water pipe and fittings, the
minimum pressure rating is PN1.0.
CAUTION: There is a tube at the hot outlet connection of the water heater. Please do not
remove or damage it during installation process. As the threaded joints are screwed in, the
tube would be installed into right depth.
