6.1.3 Watermaker

To solve the problem of water supply and to ensure a constant availability also during long navigations, the yacht has been provided with an efficient watermaker system.

The watermaker is installed in the engine room and, by means of an electric pump, sucks sea water through the service sea cock and, after filtering and treating it, sends it to the on-board tank.

Before the sea water is treated, it is filtered in order to remove all “suspended” particles, such as small seaweed and impurities in the water, which could clog the inner membranes of the watermaker, even within a short amount of time.

Excess water and salt concentrate are discharged overboard. In order to prevent the problem of the deposit of salts on the inner membranes and their crystallization over time, the system has been provided with an end-of-cycle flushing system which uses fresh water. Given the importance of this operation, clean the inner membranes of the watermaker according to the procedures and the schedules indicated by the manufacturer.
On the general electrical panel in the engine room (230V mains), there is a magneto-thermal breaker which supplies and protects the watermaker system.

CAUTION

The watermaker is to be kept in good condition by scrupulously following the indications in the specific manual. Bad maintenance can lead to production of non-potable water unsuitable for food use.

CAUTION

The watermaker does not eliminate all dangerous agents present in polluted waters (see specific manual). Use the watermaker only in clean waters, to avoid contamination of its membranes, tanks and of the whole circuit.

CAUTION

In order to prevent clogging the watermaker filters and membranes, do not use the system where sea water is dirty or contains a great deal of sand in suspension.
