The watermaker is normally fixed on the support structure by passing bolts. The max. allowed room
temperature must be 40°C.

2.3 Water intakes
The necessary hydraulic intakes are:
•
Seawater intake.
It is ideal a specific sea water intake, size ¾” min. in a central position, well under the water surface
even when the vessel is well heeled over.
The skin fitting is recommended. It must be oriented to the bow of the boat.
As alternative it is possible Tee into an water inlet as long as the following conditions are met:
- 3/4” minimum size,
- No air can be introduced into the system from other use ie: salt water tap in galley
-Must always be under the water surface even when the vessel is well heeled over.
Allow a minimum ½” on-off ball valve on the water intake. The hose connections, especially if under
the seawater level, must be secured with double hose clamps.
It is not advisable to Tee into the engine cooling water intake as it may impair the cooling of the en-
gine.
•
Fresh water intake for washing.
Tee in downstream of the vessel's fresh water pressure system (Domestic water from tank) .
The following conditions must be respected :
The flow of the existing fresh water pump must be
min 18 lit/min.
Flushing must always be carried out executed with the pressure water system ON.
•
Salt-water waste. (After passing through the watermaker)
The salt-water drain shall be ½” minimum size and it has to be preferably above the seawater level.
It is possible to use offtakes from existing apparatuses, provided that it is not the engine cooling wa-
ter drain or apparatuses that drain out water with elevated pressure.
