Safety group
When water is heated to 60 °C, it expands by 2%. A pressured tank could burst without a safety valve keeping excess water out. The
safety valve should therefore drip during warming up.
The end of the overflow pipe must be visible, and it must be able to run out safely via the drain.
CAUTION
Safety group must be installed in connection with hot water tanks.
Installation:
a. The double nut is attached to the water heater´s cold water pipe so that the
arrows are pointing in towards the water heater (in the direction of the flow).
The joint with the water heater is sealed using a threaded washer.
b. The joint between the double nut and the unit is sealed using fibre packing.
c. The rubber ring seal (the O-ring) is fitted to the unit so that it can function as
a seal between the safety valve and the unit in such a way that the valve is
locked.
ATTENTION
s water expands as it heats up, the safety valve will drip.
ATTENTION
The installer is responsibly to instruct the consumer about the location and function of the safety valve, as well as that
the safety group at least twice a year should be tested to avoid overgrowth.
