5.3 Installation of the fittet heater

Apart from the legally acknowledged rules and regulations, the connection conditions of the local power
station and waterworks must also be observed.
1.
Remove protection cover, Pos. 1.
2.
Install heating flange, Pos. 2, with gasket, Pos. 3, in the boiler. During installation, the sensor protection
tube of the temperature controller must be above the tubular heating elements (refer to "Notes on
Installation").
3.
Fasten heating flange, Pos. 2, with M 12 flange bolts (max. torque: 25 Nm ±5). The lock washer enclosed
in the plastic bag is used to establish a secure earthed connection between the flange plate and tank.
When installing the built-in electric heater with a flange screw, this must be slid on and screwed in
together. Tighten flange bolts (after tightening a bolt, proceed with the bolt in the diagonally opposite
position). Check the screw connection of the heating elements and if required retighten to a torque of
2-3 Nm.
4.
Make the electrical connection according to the wiring diagram (see Items 5/6).
Important – do not forget to connect the protective conductor!
5.
Attach protection cover and fasten with nut, put on enclosed control dial, Pos. 4.
6.
Do not operate until the tank is filled with water.
The installation of the heating element and commissioning must be carried out by a skilled
person who assumes the responsibility for the proper execution and configuration in his/her
capacity as a professional.
Installation instructions for installation with B-Label storage:
To fit the cover properly, the side bars must be removed before installation. The types EBH RSW 12 kW and
EBH RSW 15 kW can not be mounted due to the additional PG 9 screw connection.

5.4 Notes about protection against corrosion

The fitted heater is designed for installation in a tank with inside enamelling with a protection anode. As
delivered, the type series R...18 –... (flange diameter: 180mm) is equipped with an anode with a diameter
of 22 mm, length: 390 mm.
For enamelled boilers (third-party products), it is necessary to integrate an appropriate anode protection in
the boiler according to the manufacturer's specifications.
The protection anodes must be replaced when more than
approximately 2 years of operation, the anode should be checked for the first time. The degradation
products of the magnesium anode can precipitate as dissolved matter in the bottom area of the tank and
also be rinsed out from the tank during the water withdrawal.
The following measures are required in the event of a combination with CrNi (NIRO) tanks or CrNi heat
exchangers and built-in components in plastic coated tanks:
a)
Disconnection of the protective current discharge resistor in order to ensure an insulated
installation of the heating element.
b)
Disconnection of the anode – earth connection cable if the relevant type is equipped
with an anode.
c)
Replacement of the brass sensor tube for a sensor tube made of stainless steel.
If an external current anode is retrofitted, the magnesium anode installed must be removed as otherwise
the functioning of the external current anode will be
/
of the material has been consumed. After
