I.5. First Start Up.
•
Check if all connections have been properly made and if the voltage at the
terminals is the appropriate one.
•
Check if the Sea Cock Valve (1) is opened. In case the optional valve (11) is not
installed, its connection to the main tank will be removed.
•
Make sure there is pressure in the boat’s fresh water circuit.
•
Switch on the system by pressing the “PRODUCCION” button and check that
the pump’s direction of rotation is correct, gradually increase the pump’s motor
speed with the “
▲
”
button making sure not to exceed the 60Kg/cm
2
,high
pressure (red zone) indicated on the high pressure pump gauge (9).
•
Check that pressure in the control panel pressure gauge (5) lies between
approximately 12 and 14 kg/cm
2
, and does not exceed 15 kg/cm
2
under any
circumstances (red zone).
•
The high pressure, indicated on the high pressure pump gauge (9), will gradually
rise until stabilizing at approximately 45-60 kg/cm
2
.
•
In the first few minutes, some air bubbles will be observed in the panel control
flow meter (12). Those bubbles come from the interior of the membrane and other
system elements, causing some irregularities in the first high pressure work
cycles. They usually go away without purging the circuit.
•
Approximately 5 minutes after the start-up, the “test tank” (17) should contain
about 5 liter of water produced in model 60 l/h (7.5 liter in model 90 l/h), which
determines that the production rate is correct, press STOP to stop the feed pump,
and after that, by pressing the FLUSH button the system will activate the electro-
valve (19) and the pump will work at slower speed for about 2 minutes, stopping
automatically once finished the flushing. By that time, a significant reduction in
both high and low pressure will be noticed, due to the fact that the fresh water will
has reached the membranes. This operation must be repeated twice at least, to
clean the new membranes and eliminate the membrane preservative that may have
accumulated inside them. During the flushing, the pressurized fresh water system
on the boat must be “ON”, providing approximately a 10 liters per minute flow.
