Assembly - Commissioning
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
Attention
materials, teh tank has to be connected to earth.
The installation of splash guards or other narrowings into the connection pipe
Attention
between the solar tank and the safety valve is not permitted.
The minimum connection diameter of the safety valve must be DN20-¾".
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
Attention
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
accordance 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 destruction
of the storage tank.
To reduce the flow noises within buildings, the pipe pressure should be set to approx.
3.5 bar.
Attention
Since washed-in foreign particles clog up fittings etc. and cause corrosion in the lines,
a drinking water filter must be installed in the cold water supply.
