Installation / Assembly

The solar 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.
Install insulation before installing tubing.
The solar tank must be connected according to the pipework diagram on page 12. Only
a component-tested safety valve may be used. No shut-off system may be installed
between solar tank and safety valve.
If hot and cold water connections of the tank are provided with non-metallic tube mate-
Attention
rials, teh tank has to be connected to earth.
The installation of splash guards or other narrowings into the connection pipe between
Attention
the solar tank and the safety valve is not permitted.
The minimum connection diameter of the safety valve must be DN20-¾".
Attention
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 exits 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 solar 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 solar 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.
Since washed-in foreign particles clog up fittings etc. and cause corrosion in the lines,
Attention
a drinking water filter must be installed in the cold water supply.
