1.2 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.
! 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.
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!
1. Operating instructions
for the user and the qualified installer
1.1 Description of unit
The SHZ 30 - 150 LCD wall-mounted water
heaters with electronic control can provide
hot water up to around 85°C to suit
individual 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
A . The wall-mounted
water heater has active corrosion protection
provided by a built-in parasitic current anode.
!
Temperature adjustment from 20 °C to
85 °C is possible using the
and
buttons. On reaching 55 °C for the first
time, the heating process is interrupted for
a brief period for automatic temperature
correction.
! The water content is heated to the preset
temperature.
! The heating period is dependent on the
storage capacity, cold water temperature,
and heating capacity, see diagram
C .
! Unvented (pressurized) operating mode
is possible for the supply of several draw-
off points.
! Vented (pressureless) operating mode is
possible for the supply of one draw-off
point.
! Single-circuit operation
Automatic reheating takes place as a
function of the power supply.
! Dual-circuit operation
These units provide basic heating, which
automatically heats up the water content
during the off-peak period.
Rapid heating can be switched on when
required using the
button (keep
pressing the button until the heating-up
display symbol appears). 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
(keep pressing the
button until the heating-up display symbol
appears).
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.
1.3 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.
1.4 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.
