Positioning and fixing the backflow preventer
The
EGO PRIME
solar collector with integrated storage is protected from negative pressu-
res by a backflow preventer (or air feed valve) that is assembled on the outflow connection.
This valve comes already pre-installed but it needs to be correctly orientated and anchored
by the installer.
For the coupling, use the pair of flat ¾’’ gaskets supplied with the collector. For ensuring cor-
rect operation of the valve and the validity of the warranty of the collector, the aforementioned
by-pass valve must never be isolated, obstructed or covered. For the correct positioning please
refer to the installation diagram in the “HYDRAULIC CONNECTION” section.
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. A maximum tightening force of 20 Nm can be applied to
the plastic connections and the valve body (it is best to use a torque wrench to avoid excee-
ding this value).
A valve that is not positioned correctly can easily become clogged or dirty, which results in loss
of functionality and leaks. No guarantee rights will be recognised if the previously mentioned
valve is not installed or is installed incorrectly.
Pressure reducer
It is obligatory to install a
PRESSURE REDUCER
calibrated to 3 Bar; for the correct positioning
please refer to the installation diagram in the “HYDRAULIC CONNECTION” section.
The pressure reducer is available as an accessory (see the “ACCESSORIES ON REQUEST”
section)
In case of failure to carry out the proper installation or maintenance, or if the calibration of the
pressure reducer is incorrect, the producer will not acknowledge any warranty rights.
For facilitate this operation, read the instructions
supplied with the product.
