I.6. Start-up
•
Before starting up the system make sure the sea cock valve (1) is completely
open
.
•
Ensure there is pressure in the boat’s fresh water circuit.
•
Start the motor and check that the pressure in the low pressure gauge (5) lies
between approximately 10 and 12 kg/cm
2
, and does not exceed 15 kg/cm
2
under
any circumstances (red zone).
•
High pressure will gradually rise until stabilizing at approximately 45-60 kg/cm
2
.
There may be some differences depending on the temperature and salinity of the
water.
I.7.Turning the unit off.
Before turning off the unit the system must be cleaned to prevent a compaction of the
membranes due to the biological fouling in it, proceed as follows:
•
Press STOP to stop the low pressure motor pump.
•
Press LAVADO/ FLUSH and the system will run the flushing system.
•
At this point the unit will take fresh water from the pressurized fresh water system
in the boat. The low pressure pump must be ON, providing approximately a 10
liters per minute flow.
•
For a proper cleaning of the membranes, the feed pump will work for 2 minutes
timed period, and it will be done approximately at 60% of its normal performance.
