I.1. Installation.
(See diagram Chapter I Pages 1 and 2)
To install the unit the following inlet and outlet connections are needed:
•
Sea cock valve (1) with a minimum nominal pitch of 3/4” Gas for sea water
intake, which should be installed as low as possible at the bottom of the hull in
order to prevent possible cavitation problems due to air suction.
•
½” Gas female thread through-hull fitting (15) to connect the internal blue tube
Ø15 that drains rejected the water into the sea.
•
¼” Gas female thread inlet in the main tank for the intake of fresh water produced
•
Ball valve installed in the water line pressure out of the boat with female
R ½ "Gas for water intake (18) Wash System.
•
Options: Three way valve (22) for winter storage and valve (11) for a direct take
of the produced fresh water.
WARNING
It is very important to place the feeding assembly below the waterline and to check
that at least a minimum flow of 15 litres/ minute is supplied to the system to prevent
the pump from cavitation due to fall in pressure.
The rest of the components belonging to the unit can be installed at a higher level,
provided that they do not exceed a distance of 4 or 5 metres.
The membranes are normally delivered assembled inside their containers. In case
they haven’t been factory-installed, look in chapter IV for the assembling
instructions.
After all components have been placed and fixed, the unit will be ready for hydraulic and
electrical connection, which will be covered in the following sections.
