•
The high pressure will fall to around 20-30 kg/cm2. This significant decrease in
high pressure means that the seawater contained in the membranes has been
cleaned out and replaced by fresh water. Changing the salinity and pH of the water
in the membrane prevents the biological fouling from latching on to the
membrane for a maximum period of 90 days. For longer periods see Chapter II,
Storage and Cleaning.
•
As a safety measure keep the seacock valve closed (1) when the system is
switched off.
I.8. Maintenance of the unit.
•
Regularly check the status of the Sea Strainer (3) and clean the mesh when
needed.
•
Replace the 5 micron filter with a new cartridge at the beginning of each season or
every three months of continuous service.
•
Change the charcoal cartridge at least once a year.
•
When the pressure indicated in the high-pressure gauge (9) exceeds 65 kg/cm
2
(with a water temperature between 18ºC and 25ºC), the membrane should be
replaced by a new one.
•
Periodically check the pressure in the accumulator (7), it should be a 8 Kg/cm
2
pressure without producing low pressure oscillations.
(An annual inspection by the Technical Support Service is recommended).
