22 MINIMUM WATER FLOW VALUES
INSIDE THE PANELS
If the speed of the water in the panel pipes is too low,
the water will not be able to discharge the air.
This could cause a blockage in the circulation of the
water with a substantial reduction in the thermal
emission of the panel.
When determining the size of the systems, it is ad-
visable to make sure that the speed of the water
in every single pipe is never lower than the values
shown in the chart.

24 ASSEMBLY WITH WELDING
Align the pipes of the head and intermediate el-
ements, check the clearance between the panels
and clamp with the pliers. Weld the pipes as per the
numbered sequence. Fit the connector cover plate as
shown in the "assembly with fittings" section.
