Instructions for the installation, use and maintenance of Tecnicomar watermaker
5-19
If the produced water salinity increases, contact the Tecnicomar Service center.
Follow the SHUT DOWN steps for a correct and safe system power-off:
Depressurize the system by turning the pressure control valve (I) counterclockwise (ignore this point if the unit is
equipped with the
automatic pressure regulator
device).
Push STOP.
Switch off the power supply.
Close the sea water inlet (A2).
5.3
Manual running mode (c/w
automatic pressure regulator
device)
In case you need to pressurize the unit manually:
Start procedure
Turn the selector automatic/manual located onto the motorized valve (I) in “manual” position (when the unit is
off).
Start the unit and turn the handle located top of the motorized valve (I) until reading 60 bar on the display (HObar).
Stop procedure
Push STOP and turn back the handle top of the motorized valve (I).
Move back the selector automatic/manual located onto the motorized valve (I) in “automatic” position.
5.4
Operation in low- or high-salinity areas
Tecnicomar watermakers may also operate in areas with unknown feed water salinity, like lake or river waters.
In low-salinity areas the applied operating pressure should be less than 60 bar. In such cases the produced water flow
rate should be taken under control when applying the operating pressure.
The fresh water production must never exceed the system maximum production (refer to system
technical characteristic, Section 9).
5.5
Operation in cold areas
In very cold areas and in high salinity areas there will be a decrease in the fresh water production. In such conditions the
operating pressure must always be kept at 60 bar (850 PSI).
Never operate the watermaker at a pressure exceeding 60 bar (850 PSI)
