Assembly

The floor-standing hot water tank may be installed only in a frost-
protected area. Otherwise, it must be emptied in case of danger
of frost. Provide enough soil bearing capacity.
Connection to boiler:
The floor-standing hot water tank must be connected according
to the pipework diagram on page 13. Only a component-tested
safety valve may be used. No shut-off system may be installed
between floor-standing hot water tank and safety valve.
The installation of splash guards or other narrowings into the
supply pipe leading to the safety valve is not permitted.
The connection diameter of the safety valve must be:
Contents of the floor-standing
hot water tank in litres
up to 200
more than 200 and up to 1000
The exit pipe must be at least equal in size to the safety valve outlet
cross-section, may have no more than 2 elbows and a maximum
length of 2 m. If 3 elbows or a length up to 4 m are absolutely
required, then the total exit pipe must be designed one nominal size
larger. The use of more than 3 elbows or a length over 4 m is not
permitted. The exit pipe must be installed with downward gradient.
The drain pipe behind the drain funnel must have at least twice the
cross section of the valve entry. In the proximity of the exit pipe
of the safety valve, generally on the safety valve itself, a warning
label must be attached with the following text:
„During heating, water may exit from exit pipe for safety
reasons! Do not plug the pipe!"
The selection of pipework material (i.e. connection fittings on
site) has to be in accordance with the rules of engineering and
possible electro-chemical reactions have to be taken into account
(mixed component installation).
The floor-standing hot water tank must be installed in such a way
that it can be emptied without dismantling.
The installation of a pressure reducing valve is generally
recommended. The permissible operating pressure of the floor-
standing hot water tank on the industrial water side is 10 bar. If
the mains is operated with a higher pressure, a pressure reducer
must be installed. To reduce the flow noises within buildings, the
pipe pressure should be set to approx. 3.5 bar.
Since washed-in foreign particles clog up fittings etc. and cause
corrosion in the lines, it is recommended to install a drinking water
filter in the cold water inlet.
