10/ This product is not intended for use at altitudes exceeding
3,000 m.
11/ A safety device (or any other new pressure relief device)
measuring 1/2" with a pressure of 0.7 MPa (7 bar) must be
installed in a frost-free location at the water heater inlet, in
accordance with the local standards in force.
12/ The drainage device for the safety unit must be activated
periodically (at least once a month). This operation ensures any
limescale deposits are removed and enables you to check that the
appliance is not blocked.
13/ 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.
14/ Connect the safety device to a discharge pipe kept in the open
air, in a frost-free environment, sloping continuously downwards to
drain off the heat-expanded water or to allow for drainage of the
water heater.
15/ Your pipes must be able to withstand 1 MPa (10 bar) and
100°C.
16/ If PEX pipes are used, installation of a thermostatic regulator
at the water heater outlet is strongly advised. It will be adjusted
according to the performances of the material used.
17/ Drainage: switch the electric power supply and cold water off,
open the hot water taps then operate the drainage valve of the
safety device.
NOTE: for water heaters under sinks, disconnect the hydraulic unit
and turn it upside down to drain.
18/ Before removing the cover, check that the power supply is
switched off to avoid any risk of injury or electrocution.
19/ Upstream of the appliance, the electrical installation must have
an all-pole cut-out device (circuit-breaker, fuse) in accordance with
the local installation rules in force (30 mA earth-leakage circuit-
breaker).
20/ If the power cable is damaged, it must be replaced with a cable
with the same characteristics or a special pack available from the
manufacturer or the after-sales service.
