Depending on the nominal pressure, an 0.7 or 0.8 MPa (7 or 8 bar)
safety device (or any other new pressure relief device) measuring
½” or ¾” must be installed in a frost-free location at the water
heater inlet which complies with the local standards in force

The pressure relief valve drainage device must be activated on a
regular basis in order to remove limescale deposits and to check
that it is no blocked.
12.
No hydraulic accessory must be located between the safety
device and the unit’s cold water inlet. A pressure reducer (not
supplied) is required if the supply pressure is greater than
0.5 MPa (5 bar) and will be installed on the main supply pipe.
13.
Connect the safety device to an uncovered, constantly downward-
sloping drain pipe in a frost-free location intended to evacuate the
expansion water from the water heater or for use when draining
the water heater.
14.
The pipes used must be able to withstand 1 MPa (10 bar) and 100°C.
15.
To drain the unit, switch the electric power supply and cold water
off then open the hot water taps to operate the drainage valve of
