2.1
GENERAL
Before installing the valve, it is necessary to make sure that:
it can be inserted in the forecast space and is sufficiently accessible for performing the following maintenance operations (see
overall dimensions in table 2.1);
the inlet and outlet pipings are on the same level and are able to support the valve weight (see weights table 2.2);
the inlet/outlet connections of the piping are parallel;
the inlet/outlet connections of the regulator are clean and the regulator itself has not been subject to any damages during
transport;
the inlet piping has been cleaned in order to remove any residual impurities such as welding scraps, sand, paint residues, water,
etc.
The arrangement normally forecast is the one shown in fig. 2.
