IMPORTANT!
Be sure to fill the water heater with
water before connecting it to the electrical supply!
Failure to comply with the electrical connection con-
ditions affects the safety of the appliance, whereby
the water heater must not be operated.
IMPORTANT!
Observe the maximum permissible
pressure (see chapter: Technical data).
Further important notes
• The appliance is under pressure. During
heating, expansion water may drip from the
pressure relief valve.
• Operate the pressure relief valve regularly to
prevent it from being stuck, e.g. due to limesca-
le deposits.
• Install a type-tested pressure relief valve in the
cold-water supply line. Note that depending on
the pressure of the supply, you may also need a
pressure reducing valve.
• Mount the pressure relief valve with the ope-
ning facing down.
• Mount the pressure relief valve and the drainpi-
pe with a steady downward slope in a frost-free
room.
• Dimension the drainpipe to allow the water to
flow off unhindered when the pressure relief
valve is fully open.
• The pressure relief valve opening must remain
open to the atmosphere.
• This device contains a support battery, which is
not replaceable. It is necessary for the display
to function at night. A defect does not limit the
basic functionality.
• This unit may be operated up to an altitude of
4000 m above sea level.
Technical data
This water heater can provide hot water from the
public water supply system for several consumers.
The water used for heating must comply with the
requirements in the normative documents for do-
mestic water, in particular: Chloride content up to
250 mg/l; electrical conductivity more than 100 µS/
cm, pH value 6,5-8 for enamelled hot water tanks.
The thermal insulation consists of CFC-free poly-
urethane foam.
