4.2 Components mountings
4.2.1
Pump group
The diaphragm pump is a self-priming type, so it may be installed relatively above the seawater level. Anyway,
it is suggested to install the pump group as low as possible respect to the seawater level and as close as
possible to the water inlet; furthermore, the pump cannot run dry. Therefore, it is very important avoiding to
start the system if the intake valve is closed or if inlet filters are clogged.
The pump group should be installed in an adequately ventilated room, with the purpose to facilitate the cooling
of the motor, and not subject to condenses or drippings.
The max permitted room temperature must not
exceed 45°C
.
Avoid the contact or the proximity with inflammable material or liquid, since the motor surfaces can reach
elevated temperatures. Avoid locating the pump wherever a possible loss of water can involve damages or
jeopardize its safety. The pump must be installed on a base sufficiently horizontal, suitable to sustain the
weight of the group. The pump is normally fixed on the support structure by passing bolts.
4.2.2
Watermaker group
Concerning the watermaker unit installation there are not height limits respect to the seawater level. Anyway,
it should be installed above both pumps.
Avoid to install the system wherever any possible leak may cause damages to the boat or jeopardize its safety,
since possible leaks due to accidental causes (pipe bursting, hose clamp loosening, equipment failure, etc.)
may cause water losses.
The hydraulic intake and outlet connections are positioned on the left of the unit. Therefore, it is necessary to
foresee a minimum distance of 20 cm. to allow the pipes laying. The watermaker unit must be installed on a
base sufficiently horizontal, suitable to sustain the weight of the group.
The max allowed room temperature
must not exceed 40°C
. It is advisable to install the unit in such position to make the instrumentation easily
visible, and make the valves (located on the right of the unit) easily accessible. The watermaker is normally
fixed on the support structure by passing bolts.
4.2.3
Accessories
The non-return valve has to be installed vertically as close as possible to the seawater intake, following the
direction of the arrow.
The active carbon filter (and the attached electrovalve) has to be placed next to the pump group, if possible,
on a vertical side easily accessible.
4.3 Installation
4.3.1
Water intakes and discharges
For a correct installation of the watermaker it is necessary to arrange the following water intake and discharge
out of the board:
•
Seawater intake.
•
Fresh water intake for washing.
•
Brine disharge.
