Packages of this type, fitted with a tempering
valve (blender valve) can be used. A drop tight
pressure reducing valve MUST be fitted if the
supply pressures exceed 5 bar running.
An expansion vessel MUST be fitted and
regularly maintained to ensure the unit is not
damaged by excess pressures. This may already
be installed externally or internally within
the thermal store (check with thermal store
manufacturer).
