SPECIAL INFORMATION
- The appliance may be used by children over 8
years of age and persons with reduced physical,
sensory or mental capabilities or a lack of ex-
perience and expertise, provided that they are
supervised or they have been instructed on how
to use the appliance safely and have understood
the potential risks. Children must never play with
the appliance. Cleaning and user maintenance
must not be carried out by children without
supervision.
- Observe all applicable national and regional reg-
ulations and instructions during installation.
- Observe the minimum clearances (see chap-
ter "Installation/ Preparations/ Siting the
appliance").
- Observe the requirements concerning the instal-
lation room (see chapter "Specification/ Data
table").
- The connection to the power supply must be in
the form of a permanent connection. Ensure the
appliance can be separated from the power sup-
ply by an isolator that disconnects all poles with
at least 3mm contact separation. This require-
ment can be met by contactors, isolators, fuses,
etc.
- Observe the safety measures to prevent contact
with dangerous 'live' currents.
- Observe the fuse protection required for the ap-
pliance (see chapter "Specification/ Data table").
- The power cable must only be replaced (for ex-
ample if damaged) by a qualified contractor au-
thorised by the manufacturer (connection typeX).
- The appliance is pressurised. During the heat-up
process, expansion water will drip from the safety
valve.
- Regularly activate the safety valve to prevent
it from becoming blocked, e.g. by limescale
deposits.
- Drain the appliance as described in chapter "In-
stallation/ Maintenance and cleaning/ Draining
the cylinder".
- Install a type-tested T&P valve using the corre-
sponding connection on the appliance.
- Install a type-tested safety valve in the cold water
inlet line.
- The maximum pressure in the cold water supply
line must be at least 20% below the response
pressure of the safety valve. If the maximum
pressure in the cold water supply line is higher,
install a pressure reducing valve.
- Fit the drain pipe of the safety valve with a con-
stant fall and ensure that it is free from the risk of
frost.
- Size the drain pipe so that water can drain off un-
impeded when the safety valve is fully opened.
- The safety valve drain aperture must remain open
to atmosphere.
