5. The following must be observed
The heater is installed as shown in the immedi-
ate vicinity of the outlet in a frost-free room.
We guarantee trouble-free operation only if
GERMAN POOL fittings and accessories are used.
Note the following during installation:
• Installation must comply with all statutory
regulations, as well as those of the local elec-
tricity and water supply companies.
• Check technical data and the information on
the rating plate.
• Ensure that all accessories are removed from
the packing materials.
• Easy access to the appliance shall be guaran -
teed at all times. An external shut-off valve
has to be installed.
• Thoroughly rinse the water pipes before con -
nection.
• Optimum operation is ensured at a water
flow pressure of 0.2 to 0.4 MPa (2-4 bar). The
appliance must not be subjected to pressure
exceeding 1 MPa (10 bar).
Important notice for closed
outlet installations:
If a non return valve is neces­
sary for installation it must be
installed in the hot water outlet line
after the instant water heater.
A non return valve must NOT be fitted in
the cold inlet line before the appliance!
If the flow rate is too low, if the flow pressure is too low, or if the warm-water valve is closed, the appli-
ance switches itself off automatically. For an optimum flow of water, always fit the special jet regulator
enclosed with the appliance. This regulator is screwed into the thread on the end of the tap. If the thread
of the chrome-plated sleeve does not fit your tap, you can insert it into any standard sleeve M22/24.
The maximum possible outlet temperature is determined by the temperature of the incoming water, the
rate of flow and the heating power of the heater. The flow rate can be preset inside the appliance to
achieve the selected temperature between about 30 °C and 50 °C.
