2. Description of Appliance
This instantaneous electric water heater is intended to provide the economical heating of water sufcient for a
single outlet, i.e. handwash basin, and is installed together with a sanitary water tting.
When the hot water tap is opened, the instantaneous electric water heater switches itself on automatically
and heats the water as it passes through the appliance. It is only then that the appliance uses electricity.
The temperature increase depends on the ow rate.

3.2 Installation instructions
The heater is installed as shown in the immediate vicinity of the outlet in a frost-free room. We guarantee
trouble-free operation only if German Pool ttings and accessories are used.
Note the following during installation:
• Installation must comply with DIN VDE 0100 and EN 806 and with the statutory regulations of the country
and the provisions of the local electricity and water supply company.
• Check technical data and the information on the rating plate under the cover.
• Ensure that all accessories are removed from the packing materials.
• Easy access to the appliance shall be guaranteed at all times. An external shut-off valve has to be installed.
• Thoroughly rinse the water pipes before connection.
• Optimum operation is ensured at a water ow pressure of 0.2 to 0.4 MPa (2–4 bar). The appliance must
not be subjected to pressure exceeding 1 MPa (10 bar).
• For safe operation of this instantaneous water heater, a non return valve is not required. If, nevertheless,
a non return valve has to be installed, it may only be placed in the hot water outlet line behind the instan-
taneous water heater.
• The minimum requirements for the required water resistance must be complied with. The required water
resistance of the can be obtained from your water supply company.

Do not switch on the electric power at this time!
1. To purge the instantaneous water heater, open the hot water tap and wait until the water emerges free
of air bubbles.
2. In order to obtain an optimum water jet at low ow rates, screw the enclosed special tap aerator into
the tap outlet.
3. Switch on the electric power.
4. Adapt the water ow if necessary, if for example the temperature is not reached. The procedure is
described in the chapter “Use”.
5. Explain the functions and use of the instantaneous water heater to the user and hand over these
operating instructions to the user for information and future reference.
6. Register the appliance with the customer service department using the registration card or online at
www.germanpool.com.
3.Installation
As soon as the hot water tap is opened, the instantaneous water heater switches on automatically. Close the
tap and the appliance switches off automatically again.

4.2 Adjusting the water ow and temperature
May only be carried out by a specialist.
Remove the cover, undo the hood screw underneath and remove the hood.
The maximum temperature and ow depend on the conditions at the installation site.
In case of quite low or high cold water temperatures, you may reduce or increase the ow with the adjustment
screw to achieve a comfortable outlet temperature. See gure below for direction of rotation:
Decreasing the ow rate: Turn the adjusting screw clockwise to decrease the ow rate, thus making a higher
outlet temperature possible.
Increasing the ow rate: Turn the adjusting screw counter-clockwise to increase the ow rate, thus reducing
the possible outlet temperature.

4.4 Purging
Each time it is emptied (for example after work on the plumbing system or following repair work on the
appliance), the instantaneous electric water heater must be purged before it is used again.
1. Switch off the power supply to the instantaneous electric water heater.
2. To purge the instantaneous electric water heater, open the hot water tap and wait until the water
emerges free of air bubbles.
3. Switch the power supply back on again.
4.5 Cleaning and maintenance
- Plastic surfaces and ttings should only be wiped with a damp cloth. Do not use abrasive or chlorine-
based cleaning agents or solvents.
- For a good water supply, the outlet ttings (special tap aerators and shower heads) should be unscrewed
and cleaned at regular intervals. Every three years, the electrical and plumbing components should be
inspected by an authorised professional in order to ensure proper functioning and operational safety at
all times.
4.3 Changing the strainer
The cold water connection of the instantaneous electric water heater is equipped with a strainer. Dirt depos-
ited in this strainer can reduce the hot water output. Clean or replace as follows.
1. Switch off the power supply to the instantaneous electric water heater.
2. Close the shut-off valve in the inlet pipe.
3. Disconnect the water pipe from the water inlet. The water inlet is indicated in blue on the rating plate
(under the cover). This can cause water leakage.
4. Lever the strainer out of the connection piece of the
instantaneous electric water heater and clean or
replace it.
5. Insert the clean strainer into the connection piece
and connect the water pipe to the water inlet of the
instantaneous electric water heater.
6. Purge the instantaneous electric water heater as
described in the chapter “Purging”.
7. Switch the power supply back on again.
4. Use

P.16 P.17
If the connection cable is damaged, it must be replaced with an original spare cable from the manufacturer by
an authorised technician in order to avoid any hazards.
If you cannot rectify the fault with the aid of the troubleshooting table, please contact customer service and
repair centre (refer to page 35).
The following table will help you to determine and rectify the reasons for possible problems.

6.2 Environment and recycling
GERMAN POOL is conscious of the importance of
environmental protection. We extend our belief to our
packaging materials. You can help the environment by
carefully segregating waste.
The packaging is essential for protecting the components
during transportation. Electrical devices should be
disposed of separately from household waste at
the end of their service life. Please take this device
to a collection point that accepts electronic scrap.
6. Disposal
6.1 Disassembly
1. Switch off the power supply to the instantaneous water heater.
2. Close the shut-off valve in the inlet pipe.
3. Disconnect the electrical connection in the appliance junction box or disconnect the protective earth
plug if the appliance is tted with a plug.
4. Disconnect the water pipes from the connectors of the appliance. This can cause water leakage.
5. Remove the appliance from the wall bracket. To do so, insert the tip of a wide screwdriver as far as it
will go into the latch between the water connection pieces and push the latch slightly upwards. Tilt the
appliance forward by max. 15° and remove it by lifting it upwards.
6. Unscrew the wall bracket from the wall.
