I.1. Installation.
(See diagram Chapter I Pages 1 and 2)
To assemble the unit you will need to have the following inlet and outlet connections ready:
•
Seacock (1) with a minimum nominal pitch of 3/4” Gas responsible for water intake,
which should be located as low as possible on the bottom of the hull in order to
prevent possible cavitation problems due to air aspiration.
•
½” Gas female thread through-hull (15) fitting for connecting the internal blue tube
Ø
12 that drains the rejected water into the sea.
•
¼” Gas female thread inlet in the main tank for the intake of the fresh water
produced.
•
½” Gas female inlet for pressurised intake of water used on the watermaker’s
cleaning process.
WARNING
It is very important to place the sea strainer (3) as close as possible to the motor pump
(4), making shure both of them are located below the waterline, lastly, check that at
least a minimum flow of 10 liters/minute is supplied to the motor pump (4), to prevent
it from cavitations due to a pressure fall.
The other components belonging to the unit can be located at a higher level, provided that
they do not exceed a distance of 4 or 5 metres and taking into account that the membrane
(10) and the high pressure pump (8) must be connected by the 1 meter long high pressure
tubes. In longer distances, pressure drop increases significantly, increasing the power
consumption.
The membrane’s building position is irrelevant (vertical/horizontal), but in case of placing it
in a vertical position, the outlet fresh water tube has to be on the upper part.
The membrane is normally delivered assembled inside the high-pressure container. If
it has not been factory-installed look for the assembling information in Chapter IV.
After all components have been put in place and fixed, the unit will be ready for hydraulic
and electrical connection, which will be covered in the following sections.
