POSITIONING AND FIXING THE BACKFLOW PREVENTER
The
“EGO”
solar collector with integrated storage is protected from negative pressures by
a backflow preventer (or air feed valve) that is assembled on the outflow connection.
This valve is supplied installed, but must be directed correctly by the installer and fixed in
position.
When uniting, use the pair of ¾‟‟ flat gaskets that are supplied.
There is a swinging piece of PVC which shows the main phases of correct assembly; this
simplifies the operation to be carried out between the connection and valve.
A flat ¾‟‟ gasket is placed between the valve and the outflow connection in the factory; the
valve is only tightened by hand.
The valve body should be directed so that the suction element (black
plastic) is turned perfectly upwards (in other words, it must create a
90° angle as to the horizontal surface.
Before tightening the valve to
the
outflow connection,
connect between the valve
and the user supply line.
To do this, keep the plastic connection still using
a no. 36 spanner and lock the valve body by
tightening the pipe connection.
