10 Threaded bushing
11 Cable grommet
Wall mounting (Fig. II)
There are two ways in which the continuous-flow heater
can be mounted on the wall:
– Using the mounting bolt. Unevenness in the wall up to
a depth of 25 mm can be compensated for.
– Making use of the holes that were drilled for the
old heater: Use the mounting template to establish
whether the existing holes line up properly.
The following describes the installation procedure using
the mounting bolt.
Marking the point for mounting the heater and select-
ing the opening for the connecting cable (Fig. II, A)
Important!
Make sure that the connecting cable is isolated
from the mains electricity supply!
XPlace hole 3in the mounting template over the cold-
water inlet.
XSelect the most suitable hole through which the con-
necting cable is be fed. The connecting cable must
pass through one of the six holes marked 14... Termi-
nal BZ 45Z20 can be used if the cable is fed into the
water heater through one of the bottom holes marked
14a.
XMark the point 12 at which the mounting bolt is to be
inserted.
Fitting the mounting bolt and attaching the pipe
connecting pieces (Fig. II, B)
Open up the heater (Fig. II, C)
Punching out the holes at the rear of the heater for the
mounting bolt and the connecting cable

Your new appliance
The continuous-flow heater heats the water as it flows
through the appliance. The appliance only consumes
power during this period.
This appliance can supply hot water to taps in several
different locations. It should be installed close to the tap
that is used the most frequently. This will enable you to
reduce energy consumption.
How to operate the
continuous-flow heater
The continuous-flow heater has two power settings:
1Economy setting – two thirds power
2Intensive setting – full power
Multimatic
12
The 1setting is ideal for:
Wash basin
Shower
Bidet
2setting should be used where a higher temperature or
a larger volume of water is required, e. g.
Dishwashing
Cleaning
Bath tub
If you are using a thermostat-controlled mixer tap, set
the heater to 2.
1. Set the heater to either 1or 2, as required.
2. Turn on the hot-water tap.
The continuous-flow heater switches on automatically
and heats the water as it flows through the appliance.
The heater switches off again when you turn off the tap.
Increasing the water temperature
When the tap is turned on fully, it is possible that the
heater capacity is not sufficient to heat the water to the
required temperature.
XSlightly close the hot-water tap. The water flows
through the appliance more slowly and reaches a
higher temperature as a result.
Decreasing the water temperature
XMix with cold water.
Note about operation
When a hot-water tap is turned on by only a small
amount, the continuous-flow heater operates at half
power regardless of which setting (1, 2) has been
selected.
When a hot-water tap is turned on fully, the appliance
operates at the maximum level of power that corre-
sponds to whichever setting has been selected.
Saving energy
XPlease use economy setting “1” as often as possible.
To minimise energy consumption when turning off the
hot water:
– Turn off the hot-water tap slowly in order to use the
residual heat of the continuous-flow heater.
– This also prevents the water temperature from briefly
increasing above the preselected temperature if the
hot-water tap is turned on again within the next few
minutes.
To obtain particularly uniform hot-water temperatures,
it is recommended to use thermostat-controlled mixer
taps.
The thermostat-controlled mixer tap must be suitable
for hydraulically controlled continuous-flow heater.
Winter operation
Note: It is possible in winter that the supply tempera-
ture of the water is reduced and the required outlet tem-
perature is no longer achieved.
XIn order to compensate for this temperature reduc-
tion, please reduce the water quantity on the tap until
the required water temperature is achieved.
Cleaning
XSimply wipe the appliance with a damp cloth.
Do not use acidic or abrasive cleaning materials.
Notes: It is normally not necessary to descale the appli-
ance. However, extremely hard water and the frequent
flows of very hot water can cause the appliance to scale
up. In this case please contact our after-sales service.

A fault, what to do?
Attention!
Repairs must only be carried out by an authorized
technician. Improper repairs can lead to risk of
serious injury to the user.
If your appliance does not operate as required, it is of-
ten due to a very minor problem. Please check whether
you can remedy the fault yourself by using the following
guidelines. You will save yourself the costs of an unnec-
essary visit by customer service personnel.
The water does not heat up or not enough water flows
out of the tap:
XCheck the fuse in the fusebox.
XDrop in pressure in the water mains. If the pressure is
too low, the appliance will not switch on.
XThe strainer on the tap or shower head is blocked.
Unscrew the strainer and either clean or descale it.
XThe corner valve is clogged. Turn on the hot-water
tap fully and open and close the corner valve several
times. Then clean the filter in the water tap.
XThe heater needs descaling. Arrange for a service en-
gineer to visit.
The continuous-flow heater switches off during the
drawing-off of water, resulting in a reduction in the
water temperature:
XThe washer inside the hot-water tap must be a non-
swelling type.
If you cannot resolve the problem yourself, switch off
the heater via the fuse in the domestic wiring. Arrange
for a service engineer to visit.
