The instantaneous water heater DSX is a microprocessor-controlled, pressure-resistant
water heater for a decentralised water supply to one or more tap connections.
Its electronic control regulates the power consumption depending on the selected
outlet temperature, the respective inlet temperature and the flow rate, thus reaching
the set temperature exactly to the degree and keeping it constant in case of pressure
fluctuations. The required outlet temperature can be entered on a keypad within a range
between 20 °C and 60 °C and can be read off the digital display.
The maximum inlet temperature can be up to 70 °C so that operation in connection with
solar heating systems is possible.

Installing the wall bracket
If you install the instantaneous water heater DSX instead of a conventional instantane-
ous water heater, there is generally no need to drill holes for the wall holder. In this case,
you only need to screw in the double nipples (15) as described in 2. and to secure the
wall bracket.
1. Thoroughly rinse the water supply pipes before installation to remove soiling
from the pipes.
2. Using a 12 mm hexagon socket screw key, screw the screw-in nipples into the wall
connections. After tightening, the double nipples must protrude by 12 mm.

How to save energy
Set the exact temperature you need on the appliance and open the hot water tap. Once
you feel that the water is too hot, do not add any cold water and, instead, enter a lower
temperature on the appliance. If you were to add cold water, the water already heated
would cool down again and valuable energy would be wasted. Moreover, the cold water
added in the tap is not covered by the control range of the electronic circuitry, with the
result that temperature constancy is no longer guaranteed when using several taps at
once.

GEFAHR
Maintenance work must only be conducted by an authorised professional.
Cleaningandreplacingthelterstrainer
The cold water connection of the instantaneous water heater DSX is equipped with an
integrated shut-off valve and a strainer. Soiling of the strainer may reduce the warm
water output. Clean or replace the strainer as follows:
1. De-energize the instantaneous water heater by means of the house fuses and prevent
inadvertent reactivation of them.
2. After opening the hood of the unit, close the shut-off valve (12c) in the cold water
connection piece (position II).
3. Unscrew the screw plug (12b) from the cold water connection piece and take out the
strainer (12a).
4. The strainer can now be cleaned or replaced.
5. After fitting of the strainer tighten the screw plug.
6. Slowly open the shut-off valve in the cold water connection piece (position I).
7. Vent the unit by carefully opening and closing the affiliated warm water tap valve
several times until air no longer emerges from the pipe.
8. Fit the hood of the unit.Then reconnect the voltage to the house fuses.
Power limit
If the full output of the instantaneous water heater DSX does not suffice to heat the
tapped quantity of water, the control valve automatically reduces the flow rate so that
the set temperature is reached.
Operation with solar systems
When operating with solar systems, e.g. an automatic mixing tap must ensure that the
inlet temperature does not exceed 70 °C.
If the inlet temperature is too high as the result of the above reason, the appliance is
not providing any output, and the display shows “inlet temp too high”.
Venting after maintenance work
The instantaneous water heater DSX features an automatic air bubble protection to
prevent it from inadvertently running dry. Nevertheless, the appliance must be vented
before using it for the first time. Each time the appliance is emptied (e.g. after work on
the plumbing system, if there is a risk of frost or following repair work), the appliance
must be re-vented before it is used again.
1. Disconnect the instantaneous water heater from the mains by disactivating the fuses.
2. Unscrew the jetregulator on the outlet fitting and open the cold water tap valve to
rinse out the water pipe and avoid contaminating the appliance or the jetregulator.
3. Open and close the hot water tap until no more air emerges from the pipe and all air
has been eliminated from the water heater.
4. Only then should you re-connect the power supply to the instantaneous water heater
and screw the jetregulator back in.
