must be turned to the required position (position 5 corresponds
to approximately 62 °C).
4.3 Recommended settings
4.3.1 Water temperature
The water temperature is continuously variable, and can be set
subject to your requirements. The setting range extends from
approx. 5 °C to approx. 65°C (PSH 75-150 Si: 5 °C to 62 °C).
For low water consumption or very hard water, we recom-
mend setting the cylinder to a low temperature, as water above
approx. 55 °C deposits the limescale contained in it.
4.3.2 Holiday and absence
During a prolonged period of absence, such as a holiday, you
should set the appliance to frost protection or disconnect it from
the power supply, in order to save energy. To do so, observe the
details in the frost protection chapter.
4.3.3 Sporadic use
For only sporadic use, such as in a weekend home, you should set
the appliance to frost protection or disconnect it from the power
supply when you are not there. For reasons of hygiene and health,
you should heat up the content of the cylinder once to above 60 °C
before initial usage.
4.3.4 Frost protection
In the frost protection setting, the cylinder is protected against
frost, but the safety valve and water lines in the apartment or
house are not. If the appliance are disconnected from the power
supply, the cylinder is not protected against frost. In such cases,
if there is a risk of frost, the cylinder must be drained.
 Close the cold water inlet.
 Open a DHW draw-off point.
 Open the drain valve or the drain valve on the safety valve,
and fully drain the cylinder.
Risk of scalding. Hot water may emerge during draining.
5. Cleaning, care and maintenance
A damp cloth is sufficient for cleaning the casing. Do not use
abrasive or corrosive cleaning agents.
 Check the tap regularly. Remove limescale deposits at the tap
outlets using commercially available descaling agents.
 Regularly activate the safety valve to prevent it from becom-
ing blocked by limescale deposits.
 Check the safety valve is functioning correctly by pulling out
or turning the rotary selector. When you do so, water will
escape from the safety valve!
The drip water outlet of the safety valve must always remain open
to atmosphere, and must never become narrower or blocked.
Route the drip water outlet to a drain free from the risk of frost,
with a constant slope to ensure the unrestricted flow of the water
to the drain.
!Have a contractor regularly check the appliance and
safety valve.
Danger to life through electrocution! Maintenance work, such as checking the electrical
safety, must only be carried out by a qualified contractor.
To safeguard a long service life, we recommend having a cont-
ractor inspect the protective magnesium anode installed in the
appliance after the first year of service. The contractor should
determine further maintenance intervals. Annual maintenance
intervals could be necessary in areas with particularly hard water.
6. What to do if... ?
Fault Troubleshooting checks
No hot water Has the power supply (fuse or MCB) been inter-
rupted? If so, reset the fuse or MCB and wait until
the cylinder has heated up again. Notify your con-
tractor if the fuse/MCB blows/trips again after you
have reset it.
No hot water Is the temperature set high enough? Set the tem-
perature slightly higher.
No hot water Is the ON/OFF indicator illuminated? When the ON/
OFF indicator illuminates, the appliance heats the
cylinder content. This can be necessary, for example
because a large volume of water was previously
drawn. Wait until the ON/OFF indicator extinguishes
again.
No hot water Is the ON/OFF indicator illuminated? If the ON/OFF
indicator is not illuminated and all other causes
have been checked, this can indicate that the high
limit safety cut-out has responded. Notify your local
contractor.
Too little hot water Is the temperature set correctly? If all other possible
sources of the fault have been eliminated, the ap-
pliance may have been sized too small. In this con-
nection, also observe the maximum DHW draw-off
volume, as specified in the "Specification" chapter.
Low DHW outlet volume Are the draw-off points scaled up? Limescale on the
draw-off points reduces the output volume. Descale
and clean the outlet points. If this does not remedy
the fault, inform your local contractor.
The safety valve is drip-
ping
This is normal during heat-up. If the safety valve
continues to drip after heat-up is complete, inform
your local contractor.

11.3 Taking the appliance out of use
If you ever want to take the appliance out of use, carry out the
following steps:
 Isolate the appliance from the power supply.
 Close the cold water inlet.
 Drain the appliance.
The appliance can only be drained via the safety valve or via a
drain valve.
 Fully open the DHW valves on all draw-off points.
 Open safety valve or drain valve.
Risk of scalding. Hot water may emerge during draining.
11.4 Restarting
 Open the cold water inlet.
 Open a DHW draw-off point.
 Fill the cylinder until no more air escapes from the draw-off
point, only water.
 Close the draw-off point again.
 Switch the mains power ON.
12. Appliance handover
Explain to the user how the appliance works, and hand over these
operating instructions.
13. Troubleshooting
In addition to the test steps in the „What to do if...?“ chapter,
check the following:
Fault Remedy
Too little DHW Is the immersion heater scaled up? Descale it if
required.
Little or no DHW Check the controller and heating elements, and
replace if required.
No hot water. The high
limit safety cut-out has
responded because of
overheating.
Investigate the cause of the fault. If there does not
seem to be a cause, you can reset the high limit
safety cut-out. To do so, press the reset button with
a screwdriver, as shown below. If there are no pro-
blems with the heating element, but the high limit
safety cut-out continues to respond, replace the
controller/limiter combination.
No hot water. The high
limit safety cut-out has
responded because the
temperature has drop-
ped below -15°C.
Press the high limit safety cut-out reset button.
No hot water. The flan-
ged immersion heater
is faulty.
Replace the flanged immersion heater.

14. Maintenance
14.1 Maintenance work
 Check the safety valve and drip water outlet line.
 Check the protective magnesium anode and replace if
required.
 Remove loose scale deposits from the cylinder.
 If necessary, descale the inner cylinder with commercially
available descaling agents.
Do not descale the appliance until you have removed the flanged
immersion heater. Never treat the cylinder surface with descaling
agents.
 Check the electrical connection, particularly the earth
connection.
14.2 Wearing parts
Replace the protective magnesium anode if it has dissolved. Use
only original spare parts.
