Instructions for the installation, use and maintenance of Tecnicomar watermaker
5-18
5
Routine operation
5.1
Routine operation (c/w
automatic pressure regulator
device)
After having carried out the first start-up (section 4), the everyday start-up and operation of the watermaker will be
simple and fast.
Follow the START-UP steps listed below:
Open the sea water inlet valve (A2).
Start up the system by pressing START.
Check that the feed water pressure is correct: the low pressure value showed on the display should not get below
30% of the reading as it was with new filter cartridges. If necessary, clean or replace the filter cartridges. The
electric box will automatically shut down the system if the feed water pressure is below the minimum level needed
for the correct operation (0.3 bar).
Prefiltrated, clean sea water is extremely important for correct operation of the watermaker. It is
also a good help to longer life of membranes. We recommend the exclusive use of replacement
cartridges supplied by Tecnicomar.
If the produced water salinity increases, contact the Tecnicomar Service center.
Follow the SHUT DOWN steps for a correct and safe system power-off:
Push STOP.
Switch off the power supply.
Close the sea water inlet (A2).
5.2
Routine operation (c/w
manual pressure regulator
device)
After having carried out the first start-up (section 4), the everyday start-up and operation of the watermaker will be
simple and fast.
Follow the START-UP steps listed below:
Open the sea water inlet valve (A2).
Make sure that the pressure control valve (I) is open (ignore this point if the unit is equipped with the
automatic
pressure regulator
device).
Start up the system by pressing START.
Check that the feed water pressure is correct: the low pressure value showed on the display should not get below
30% of the reading as it was with new filter cartridges. If necessary, clean or replace the filter cartridges. The
electric box will automatically shut down the system if the feed water pressure is below the minimum level needed
for the correct operation (0.3 bar).
Prefiltrated, clean sea water is extremmely important for correct operation of the watermaker. It is
also a good help to longer life of membranes. We recommend the exclusive use of replacement
cartridges supplied by Tecnicomar.
Apply gradually the operating pressure (850 psi = 60 bar) by slowly turning the pressure control valve (I)
clockwise (ignore this point if the unit is equipped with the
automatic pressure regulator
device).
Check that after a few minutes of operation the UNSAFE warning disappears.
