1. Operating instructions
for the User and the Qualified Installer
1.1 Description of the unit
SH . . . A wall-mounted water heaters can
provide hot water up to about 82 °C to suit
individual requirements, and can supply one
or more draw-off points depending on the
operating mode. The water is heated
electrically.
Water is automatically maintained at the set
temperature (depending on the electricity
supply).
! Infinite temperature regulation possible
from about 35 °C to about 82 °C A (1).
! The water content is heated to the preset
temperature.
! The period required for heating depends
on the storage content, the temperature
of the cold water, and the heating capacity.
See diagram
B for heating-up time at a
temperature setting of 65 °C and a 82 °C.
! The hot water indicator enables (3) the
user to ascertain the availability of sufficient
hot water.
The indicator position is dependant on the
chosen heating temperature. If a tempera-
ture of 82 °C (maximum) has been
selected the indicator should be at the tail
end of the red graded section of the
temperature gauge, indicating that the
maximum quantity of hot water is availa-ble.
On the other hand when less then 37 °C is
selected the indicator will be at the
beginning of the red colour gradient.

82 °C = max. settable temperature.
Individual system conditions
may cause the temperatures
to differ from the reference
value.
The indicator lamp in operating panel (2)
will light up while the water is being
heated.
1.3 Important notes
A hot water temperature of more
than 60 °C may occur at the draw-off
fitting.
Children should accordingly be kept away
from the draw-off fittings due to the risk
of scalding.
– Arrange to have the wall-mounted water
heater and the safety group checked
regularly by a qualified installer.
– Check your fittings regularly. Remove
limescale from the fitting outlets with
conventional scale removal products.
Units in unvented operational mode
are under waterpipe pressure.
During heating, the expanding water drips
out of the safety valve. If water still drips
out after the heating process has finished,
inform your qualified installer.
Freezing risk
The temperature setting marked ! (= cold)
will protect the water heater against subzero
temperatures but does not afford any
protection for the safety overflow or the
water piping.
1.4 First aid in the event of
faults
See „5. Fault rectification - Users“.
1.5 Care and maintenance
Maintenance work, such as checking
electrical safety, may only be carried
out by a qualified installer.
A damp cloth is sufficient to take care of the
housing. Do not use any abrasive media
which might detach the coating.
1.6 Operating and
installation instructions
Keep these Instructions carefully. In
the event of a change of ownership,
hand them over to the new owners, and
give them to the qualified installer to read
in the event of maintenance and possible
repair work being carried out.
