1.3 System description
The
Modular 100
systems are based on 2 main units:
PUMPS AND FILTER GROUP.
This unit have the duty of picking the sea water up and send it to the watermaker unit at a certain
pressure (about 7,5 –8 Bar).
The pump is equipped with a
pressure switch
for high-pressure shutdowns, calibrated at about 12
Bar. The pressure switch can be adjusted by an 2 mm. allen key. To reach the allen key adjustment
head must be unscrew the electric connector screw, and then introduce inside the allen key (also
without remove the electric connector). Turning clockwise the allen key increases the pressure shut
down set, whereas turning anti clockwise decrease the pressure switch shut down set. The pump
group is equipped with an electric box that contain the power relay that activate the electric motor of
the pump. The terminal P1 receives the start-stop consent from the computer. The pump motor is IP
20 protected and therefore must be carefully protected from water sprays.
The orange filter, positioned between the pump outlet and the watermaker inlet, is fitted with a 5 mi-
crons cartridge, and protects the watermaker unit from sediments and debris.
