This compensates the thermal expansion of the lines caused by temperature oscillations
and makes disconnecting and repositioning the solar collector easier if it has to be
removed.
Make sure the connecting pipes, once installed, can move in order to
guarantee suitable thermal expansion.
It is advisable to use a connecting system that is not fixed (e.g. staples).
Other indications
Only use water supply pipes that are suitable for the domestic sector and that can resist a
temperature of at least 120 °C.
In order to reduce thermal dispersion and prevent the risk of freezing, it is advisable to
insulate the pipes that supply the collector with water and towards the user with insulation
material of suitable thickness; for outdoor pipes use material that is UV-resistant.
ASSEMBLING THE SAFETY AND ONE-WAY VALVE
To limit excess pressure in the hydraulic circuit, the safety and one-way valve supplied with
the collector must be installed upstream of the inflow connection.
This solution prevents the system from emptying if there is no water being supply. When
uniting, use the supplied pair of ¾‟‟ flat gaskets.
This component acts as:
- a safety valve, with opening set at 4.5 ± 0.5 bar;
- a one-way valve, to stop the water from returning to the water system.
If you want to install a discharge valve at inflow (recommended), it should be positioned
between the safety valve and the inflow connection.
The safety valve must be installed correctly; if it is not, leaks can occur. No
guarantee rights will be recognised if not installed or if installed correctly.
