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: 22 Nm). 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.

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
consumed. After 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 impaired.
