SPECIAL INFORMATION
- The appliance may be used by children aged 8
and older and persons with reduced physical,
sensory or mental capabilities or a lack of ex-
perience and know-how, provided that they are
supervised or they have been instructed on how
to use the appliance safely and have understood
the resulting risks. Children must never play with
the appliance. Children must never clean the ap-
pliance or perform user maintenance unless they
are supervised.
- Only use a permanent connection to the power
supply. Ensure the appliance can be separated
from the power supply by an isolator that dis-
connects all poles with at least 3 mm contact
separation.
- Observe the maximum permissible pressure (see
chapter Installation / Specification / Data table).
- 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 chap-
ter “Installation / Maintenance / Draining the
appliance”.
- Install a type-tested safety valve in the cold water
supply line. Please note that, depending on the
static pressure, you may also need a pressure re-
ducing valve.
- Size the drain so that water can drain off unim-
peded when the safety valve is fully opened.
- Fit the discharge pipe of the safety valve with
a constant downward slope and in a room free
from the risk of frost.
- The safety valve discharge aperture must remain
open to atmosphere.
