The supply water must be clean filtered and of excellent quality (e.g. boiler supply water) and must be at
constant pressure at all times, as specified in the order documents. Each water supply line must be
protected by its own filter with maximum mesh size of 0.1 mm (0.4 mm acceptable for nozzles from ‘E’
upwards). On request Carraro can supply a supplementary filter. The mainly application of Carraro’s filter
is to clean water from particles during the start up operations. If no other filter system is installed this filter
can be left and periodically inspected.
If closure components are envisaged in the water supply line, fit a safety valve of approved type. As for the
vapour pipe, use gaskets and fasteners which comply with the codes of the respective pipes. Flush the
water supply line before connecting the mounting flange of the desuperheater (see Fig. 5).
