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.
If hot and cold water connections of the tank are provided with non-metallic tube mete-

rials, the tank has to be connected to earth.
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:

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 accor-
dance 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.
Exceeding the permissible operating pressure may cause leakages and destruc-
tion of the storage tank.
To reduce the flow noises within buildings, the pipe pressure should be set to approx.
3.5 bar.
