1. Introduction
For reasons of easier readability, the usual masculine form of speech is used in these operating instructions for
personal nouns and pronouns. However, this does not imply any discrimination against the female gender, but is to
be understood as gender-neutral in the sense of linguistic simplification.

7. Installation & Assembly
The installation is carried out horizontally in a threaded sleeve G 1 ½" (6/4") with suitable sealants, preferably
in closed water heating systems with a nominal pressure of up to 10bar. The length of the threaded socket
must always be smaller than the unheated zone (LU), this can be found in the technical data in the table (see
chapter 6.1 Technical data) The thermally induced medium circulation in the tank must not be obstructed, e.g.
by baffles. The standards and directives applicable at the installation site must be observed during
installation. All work may only be carried out by an authorised specialist. When used in water containing lime,
from about 12°dH, the screw-in heater must be decalcified regularly. The chloride content should not exceed
the limit value of 250 mg/l, according to the drinking water ordinance. To prevent corrosion damage to
enamelled or coated tanks, the tubular heating elements of the screw-in heating element are electrically
insulated from the tank and conductively connected via a resistor, thus increasing the service life of the
protective anode and the screw-in heating element.

18
• Use suitable sealants.
• The boiler/buffer in which the heating rod is to be inserted must be drained. The
Attach the heating rod with brass thread to the socket.
7.1 Installation recommendation
Warning! The threaded sleeve must be shorter than the unheated zone (100mm) of the heating rod.

19
• Screw the heating rod into the 1 ½" (6/4") socket.
Warning! Do not screw in by turning the plastic housing!
• Tighten the heating rod at the brass screw head SW60.
Hint! The heating rod can be locked slightly after tightening so that the housing stands straight.

20
• Check the connection for leaks and fill the boiler/buffer.
Warning! The heating element must be completely surrounded by water and must not be used in dry
operation under any circumstances.
