2. Installation
2.1 General criteria
It is important to plan carefully the activity prior to start the installation works, evaluating any
possible alternative solution. The fundamental choices to make are:
Finding of seawater intakes and any necessary fittings.
Positioning of main units .
Positioning of pumps operation automatic circuit breakers.
Pipes and electric cables laying.
A well-done installation is the maximum optimization between functionality, accessibility,
installation saving and esthetic. All plant components have been designed to achieve this target.
It is suggested to draw a schematic electric and hydraulic connections layout once an installation
solution is chosen, and enclose it into the manual for further quick reference.

2.2 Components mounting
Pumps group.
The pumps are self-priming type. Anyway it suggested to install the pumps group below the
watermaker, as low as possible respect the sea level, and as close as possible respect the sea
water intake.
The pumps need to be installed in an adequately ventilated area to allow cooling and avoiding
condensation. Do not install the pumps unit close to inflammable liquids, as the pump surfaces
can become warm. Avoid locating the pump where a loss of water can cause damage or
jeopardize its safety. Allow sufficient space for access to the casing containing the filter
cartridge.
The pump must be installed horizontally on a suitable base strong enough to support its weight
when the filter housing is full of water.
It may be necessary to create a suitable wooden or fiberglass structure for the unit if an existing
one not available. The base of the pump is equipped with vibration-damping devices, but avoid
installing it on a surface susceptible to vibration.
The pumps unit can be a little noisy in operation. Possible areas for siting are: sink closets, under
berth lockers, wardrobe bases (creating a false floor above it.)
It is not recommended to fit the pumps unit in the engine compartment.
The unit can be fixed on the supporting structure using the screws supplied with the equipment
or the bolts with nuts and washers.
Watermaker group.
The watermaker unit is hydraulic. It can be installed in areas inside exposed to humidity. It can
be installed at any height inside the vessel. Avoid installing the system where a leak will cause
damage to the boat or jeopardize its safety.
The hydraulic intake and outlet connections are positioned in the standard version, on the left
hand side of the unit. It is necessary to leave a minimum distance of 20 cm. to allow for pipe
laying. Possible locations of the watermaker group are: engine compartment, under berth lockers,
cockpit lockers. Install the unit where access to valves and instrumentation is visible. The unit is
fitted with rubber mountings to prevent vibration, avoid fitting the watermaker in an area where
there is a lot of vibration. The unit can be fixed on the supporting structure using the screws
supplied with the equipment or the bolts with nuts and washers.
Non return valve.
The non return valve must be installed vertically and as close as possible to the water inlet.
