1. Operating instructions

1.1 Description of unit

The SHZ 30 - 150 LCD wall-mounted water
heaters with electronic control are intended
for the heating of cold water in accordance
with BS (British Standard).
They can provide hot water up to around
85°C according to requirements and can
supply one or more draw-off points
depending on the operating mode.
The water is heated electrically. The currently
available quantity of mixed water from 40 °C
(in relation to a cold water temperature of
15 °C) is shown on the LCD display. The
wall-mounted water heater has active
corrosion protection provided by a built-in
parasitic current anode.
Excess limescale on the element is indicated
by the limescale indication „Ca" on the
display.

85 °C is possible using the
buttons. On reaching 55 °C for the first
time (approx. 5 min), the heating process is
interrupted for a brief period for
automatic temperature correction and
activation of the limescale recognition
function.

The wall-mounted water heater is suitable
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 according
to choice.
Electrical connection can be made, according
to choice.
The symbol is displayed after each
heating cycle.
Single-circuit operation
Automatic reheating takes place as a
function of the power supply.
Dual-circuit operation
The units offer basic level heating, which
automatically heats up the water content
during the off-peak period.
Rapid heating can be switched on when
required using the button. When the
preset temperature is reached, the rapid
heating mode will be switched off and will
not be switched on again.
Boiler operation
In this switching mode the unit heats the
water content once after switching on.
Each heating process must be switched on
using the button .

1.3 Important notes

Hand
washing
A hot water temperature of more
ˆ
= 2 - 5 l
than 60°C may occur at the draw-off
fitting.
Small children should accordingly be kept
away from the draw-off fittings. 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 using
conventional descaling agents.
If the limescale indication „Ca" appears on
the display, descaling of the heating
element is recommended - inform your
qualified installer.
Units in unvented operational mode
are under mains water pressure.
During heating, the expanding water drips
out of the safety valve. If water still drips
out after the water heating process has
finished, inform your qualified installer.
Units in vented (pressureless)operating
mode:
The outlet pipe of the fitting must always
be unobstructed. Do not use any perlators
or aerators.
During each heating process, expansion
water drips out of the outlet.

The unit's steel reservoir is specially
enamelled internally and additionally has
active corrosion protection provided by the
built-in parasitic current anode. If
disconnected from the mains supply this
function ceases!
Freezing risk
The unit is protected against freezing in all
operating modes, however the safety group
and the water pipe are not.
The unit automatically switches on at 5 °C
and off at 7 °C water temperature.

1.4 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.
1.5 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.
