5.3.5. Implementation of piping connections (Welds)
Once the Panels are installed and the Combi Block has been finally placed at the site, now the following types of
piping must be placed:
✓ Liquid (Outward to panels).
✓
Aspiration (Return from panels).
Before making the aforementioned connections, it is best to carry out the connections of the panel tubes to the:
✓ Liquid distributor (s).
✓ Aspiration collector (s)
The implementation of the connections is one of the most delicate points of the whole installation and it is extremely
important that the welds are carried out in line with all the basic criteria of a quality welding process.
The recommended welding type for implementing the piping connection is oxy-acetylene welding
(oxygen/acetylene). Other types of gas may also be used such as propane, for example.
The most delicate welds and which require the greatest care are carried out at the panels. It is necessary to place
a damp fabric strip which must envelop the “Thermoretractable Joint” so that it is f uly protected from high
temperatures caused by the blowlamp flame as shown in the figure below.
The copper is heated until it goes dark red at which point welding must begin. Bring the slightly inclined welding rod
closer without exposing it to the flame. As a general rule, the quantity to be applied is the same as one and a half
times the tube diameter. As soon as the alloy expands, stop heating and let it cool.
As soon as the weld is in a solid state, you must cool the whole area around the weld immediately with a damp
cloth.
Welds alongside the Combi Block must also be carried out with due care so as not to burn any component of the
Combi Block.
You should weld the aspiration and the liquid pipe to the corresponding pipping, at the back of the Combi Block. Be
carefull with the welding process.
