Indications on gaskets and connections
The external components of the
EGO
solar collector with integrated stora-
ge are all made of plastic, to reduce thermal dispersion.
The connections were created for the use of gaskets with flat seal.
Only use the flat washers supplied with the collector and the valves to
seal the connections.
Do not use other types of seal or additional seals, such as hemp, Teflon,
sealing paste or similar. No guarantee rights will be recognised if seals
or additions other than those supplied are used.
When tightening the connections:
• make sure the gaskets are positioned correctly;
• use a spanner and a torque wrench;
• use the spanner to keep one of the two connections steady, so that it does not
move from its seat, and to prevent damaging the connection;
• tighten the other connection using the torque wrench, without exceeding a ti-
ghtening torque of 20 Nm.
• Using flexible hoses
Using flexible hoses
Only removable connections (e.g. stainless steel bellows and flexible pi-
pes) must be used to connect the water lines to the valves on the solar
collector connections.
This compensates the thermal expansion of the lines caused by temperatu-
re oscillations and makes disconnecting and repositioning the solar collec-
tor 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.
