1. Operating instructions

1.1 Description of unit

SH 30 - 150 S electronic wall-mounted
water heaters are intended for heating cold
water in accordance with BS (British
Standard). To suit requirements, they can
provide hot water up to about 82 °C and
can supply one or more draw-off points
depending on the operating mode. The
water is heated electrically in single-circuit
operation. Automatic reheating to the preset
temperature takes place automatically. The
water volume available in each situation is
indicated by lights (LED's) on the control
panel. The wall-mounted water heater is
provided with corrosion protection by means
of an incorporated signal anode.
The wall-mounted water heater can be used
optionally for:
• Unvented (pressurized) operating mode
for the supply of several draw-off points.
• Vented (pressureless) operating mode for
the supply of one draw-off point.
• Infinite temperature adjustment is possible
from about 35 °C to about 82 °C
• The heating-up process is indicated by the
A
signal lamp (2).
• The time required for heating up is
dependent on the storage content, the
cold water temperature, and the heating

• The electronic heat content display with 7

lights (3) on the operating panel shows
the heat quantity available at a particular
time. With the temperature setting you are
selecting the usable quantity of hot water.
C
The display shows the quantity of
water available as mixed water at 40 °C
(15 °C cold water inlet temperature:
65 °C temperature setting). The number
of diodes which light up is a measure of
the minimum amount of mixed water still
available at about 40 °C for bathing and
showering.
The mixed water volume is derived from
the storage size, the temperature setting of
the storage unit (from 40 °C) and the cold
water inlet temperature.
Example:
If 6 LED's light up on the SH 80 S, there
are about 160 litres of water at 40 °C
available. This means the storage unit has
enough water to fill one bath. The LED's
show at a glance whether the storage
content is still sufficient for filling a bath or
for a shower, or whether the heating-up
time must be run through first.

• If it is intended that children or persons
with restricted physical, sensory, or mental
capacity should operate the appliance, it
must be ensured that this is only done
after appropriate instruction has been
provided by the person responsible for
their safety.

1.4 Important notes

• 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.
• Units in vented (pressureless) operating
mode:
The outlet pipe of the fitting must always
be free. Do not use any perlators or
aerators.
During each heating process, expansion
water drips out of the outlet.
Freezing risk
The unit is protected against freezing in all
operating modes, however the safety group

Energy saving tip
The heat content display allows you to
A
obtain a hot water supply which is optimum
for you, energy-saving, and matched to suit
your usual consumption requirements.
How to proceed:
Start with a temperature setting of 65 °C. If,
after the largest draw-off (e.g. filling the bath),
more than one LED lights up, reduce the
temperature setting. By following this
procedure, you will determine the optimum
low storage temperature for your usual
requirements, and so reduce possible heat
losses to a minimum.

1.5 Care and maintenance

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
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.
Maintenance work, such as checking
electrical safety, may only be carried
Keep these Instructions carefully. In
the event of a change of ownership,
