HYDRAULIC SYSTEM
a way not to heat the lower part of the storage tank. Only in the case of cold return from the radiant panels
is connection possible in the lower part of the puff er. The mixing of the lower part of the storage tank with
the hot water in the system can jeopardise the solar intake to heating in the cold season.
In the TPS 500 and TPS 1000 storage tanks, the domestic hot water is produced through the large surface
fi nned copper coil. This guarantees maximum hygiene and prevents the formation of legionella. To
compensate the dilations caused by the temperature range of the water inside the coil and minimise the
ramming it is necessary to install a small expansion vessel (4 litre) and a safety valve calibrated at 6 bar.
In order to prevent unpleasant burns due to very hot domestic hot water a thermostatic mixer valve must
be installed in the domestic hot water circuit so as to obtain distribution at a constant temperature. This is
thanks to mixing the water coming from the cylinder with cold network water. Carry out water softening
treatment if water hardness exceeds 25°F.
The excessive deposit of lime scale inside the copper coil can jeopardise functioning.
Install the expansion vessel in the lower part of the puff er able to absorb the volume increase of the water
in the storage tank and install the safety valve, calibrated at 3 bar, in the highest part.
ATTENTION!!!
Check the closure of all sleeves and fl anges, in particular those positioned in the lower
part (discharge sleeve) and upper part of the tank.
Connect the puff er to earth correctly according to the standards in force.
