Installation

4.1 Regulations

The following standards, regulations and guidelines must be observed for installation and
operation:
DIN EN 806 / DIN EN 1717 / DIN 1988 / DIN 4708 / EN 12975
DVGW (German Technical and Scientific Association for Gas and Water) work sheet
W 551 / work sheet W 553
EnEG (German Energy Conservation Act) / EnEV (German regulation on energy-saving thermal
insulation and systems engineering in buildings)
Local regulations
VDE (German Association for Electrical, Electronic & Information Technologies) regulations

4.2 Transport

The heater must never be transported to the installation site in a horizontal position. Observe
the instructions on the packaging! Do not remove the heater from the packaging until it is at
the installation site. Take great care when moving the heater during transport and always
place it down gently.

4.3 Installation Site

Install the heater in a frost-proof room. Install the heater on a level and stable floor. If the
room is damp, raise the heater on a platform. If the heater is to be installed below the rooftop,
you may want to install a water collection tank with the same capacity as the heater.

Fittings required
1. Cutoff valve
2. Pressure reducing valve (if the
network pressure is over 10 bar and
the house connection does not
already feature a pressure reducing
valve)
3. Test valve
4. Non-return flap
5. Pressure gauge connection with
pressure gauge
6. Cutoff valve
7. Safety valve (max. 10 bar discharge,
vent every three months)
8. Discharge funnel
9. Drainage valve
10. Sanitary expansion vessel
11. Circulation pump

4.5 Assembly

Internal circulation should be avoided. The pipe routings in all heater circuits should
be designed such that internal circulation is avoided. It is recommended that a non-
return valve or non-return flap with backflow preventer is integrated into all heater
circuits.

4.5.1 Heating Water Connection

Connect the heating coil in the counter current operation. Do not invert the supply
and return connections. Keep the charging line as short as possible and insulate it
well. Arrange the drain valve in the charging line.

4.5.2 Water Connection

The connection to the cold water pipe must be carried out in accordance with DIN
1988 using suitable individual fittings or a complete safety group.
CAUTION! RISK OF DAMAGE THROUGH CONTACT CORROSION ON THE
HEATER CONNECTIONS!
With a copper connection for potable water, use brass or red brass
connection fittings.
Do not remove the plastic cartridges in the connections and ensure they are
not damaged through solder work. There shall be no claim for liability for
corrosion damage on the heater connections.
Use a safety valve that has been type-examination tested. This must be installed such
that it prevents the permitted operating pressure from being exceeded. The safety
valve discharge pipe should end above the drainage location in a frost-proof area
where it is clearly visible. The discharge pipe must at least correspond to the outlet
profile of the safety valve.
CAUTION! DAMAGE DUE TO EXCESS PRESSURE!
If a non-return valve is used, the safety valve must be fitted between the
non-return valve and the cold water connection.
Do not close the discharge opening of the safety valve.

4.5.3 Circulation

When connecting a circulation pipe, fit a circulation pump permitted for potable
water and a suitable non-return valve. If the connection is not going to be used, it
must be sealed against leaks and insulated.
