4-DESCRIPTION OF THE TANK/INSTALLATION

Puffer tank type SPU 300-500-800 made of steel S235JR (St 37-2).
It is not treated with corrosion protection on the inner wall of the tank, as its use is limited to closed heating systems as an auxiliary
heating tank.
It is not recommended for domestic potable water.
Insulation mounted upon delivery.
INDICATIONS FOR DESIGN
Installation
The tank must be installed exclusively in an environment protected from frost, otherwise it must be emptied if there is a risk of frost.
The formation of ice in the system can cause leaks or damage the tank.
The support base must be flat and strong in order to support the weight of the fully loaded tank.
Connection to the heating system
The tank must be equipped with its own safety devices (safety valve, expansion vessel).
It is forbidden to mount filters or other parts that restrict the inlet of the safety valve supply pipe.
Expansion vessels
All the expansion vessels must be mounted so that they can be blocked with respect to the heating system.
The locking devices must be protected against unintentional closure (e.g. valve cover protected with wire and lead seal).
Membrane expansion vessels must comply with Standard EN 13831.
The expansion vessels must be installed in rooms not subject to freezing or must be protected from freezing. The expansion vessels must
be designed in compliance with Standard DIN EN 12828.
Vent
To facilitate the vent operation the boiler is equipped at the top in the centre with a 1¼" sleeve.
Insulation
Mount the adjustment probes before inserting the insulation. The pipes must be installed after having mounted the insulation.
The tank insulation is made of polyurethane foam and coated with coupled PVC sheath (100 mm).
Keep the insulation away from open flames and welding flames.
COMMISSIONING
During the installation, positioning, electrical connection and commissioning of the tank, the relative regulations and local regulations in
force must be complied with.
The work must be carried out by a technician with the technical-professional law requirements. In addition, one must also check that the
entire system works and is sealed properly.
Before the commissioning it is absolutely essential to fill and vent the tank!
Thoroughly wash the piping and tank, fill it and vent it, check the safety valve by introducing air.
