Pressure relief valve
The pressure relief valve is set to 6 bar and controls the heat transfer medium (OEG solar
liquid SFS). The liquid must flow into a tank which withstands the high temperature and is
big enough to take the entire collector volume. The tank must be mounted such that it
can neither be removed nor overflow.
The pressure relief valve outlet must not be connected to a waste or other pipe which
connects to the normal water circuit.
Connection of the expansion tank
The expansion tank must be installed below the pump station level to avoid air
in the system.
