II.2. Shutting down for short periods of time.
Shutting down for a short period of time means when the unit will not be used for
between one day and three months. An excellent and inexpensive way to protect the
system and the membrane is the described in the Switching off the unit section which
guarantees protection against the biological fouling in the membranes. As manufacturers
we recommend that immediately after using the system you always flush it with
freshwater from the main tank passing through the charcoal filter (13) in order to get rid
of all rests of chlorine that may be in the water in the tank.
II.3. Shutting down for long periods of time.
(Recommended for experts only)
A long period of time or prolonged shutdown means when the unit will not be used for
three months or more. In this case the unit must first be rinsed with chlorine-free fresh
water, and after that stored with a chemical protector. This product inhibits bacteria
growth while maintaining a high circulation flow and salt rejection in the membrane.
Follow these instructions carefully:
1.
Before switching off the unit: make sure you have enough water in the boat’s main
tank and at the same time fill up another container with 5 liters of additional water
that will be used to dissolve the preservative. Press STOP.
2.
Press the “FLUSH” button and let the system be flushed with fresh water from the
boat tank. Remember that whenever the system is flushed, the pressurized
fresh water system must be on. After about 90 seconds the high pressure will
decrease until reaching 20/30 Kg/cm2, that fall will indicate the system has been
washed with fresh water.
