Technogel FREEZER 200/1 Instructions For The Installation, Use And Maintenance page 46

Machine operation with servofreezer
As illustrated in the drawing below, the servofreezer (3) is generally located behind the machine,
raised from the ground. The pump (2) which supplies the servofreezer must be placed near the
mixture storage tank, which in turn may be as far as 15 metres away from the freezer.
The piping that connects the servofreezer (3) to pump (2) must be made of rubber or plastic. We
strongly advise not to use metallic piping.
In case Technogel S.p.a. has supplied only the servofreezer and that the Client must install the
pump, we recommend installing a centrifugal pump with a maximum head of 10 metres (thrust
pressure).
In case the storage tank is positioned above the freezer (for example, on the floor above), just
connect the tank outlet directly to the servofreezer, without the aid of a pump.
