5. Maintenance:
Manual Flush
Next to the pre filter there is a valve. The valve is connected to the fresh water system of
the boat and turning it, will automatically start the boat’s water pump and a flow of fresh
water from the tank to the watermaker.
1.
Don’t turn the watermaker ON . Leave it on it’s OFF position.
2. Turn the pressure dial all the way anti clockwise.
3. Turn the valve of the fresh water intake, which is located next to the filter, for 2
minutes. The boat’s water pump will start and fresh water will run through the
watermaker.
Automatic Flush
After using the watermaker,
don’t switch it off.
While the watermaker is still running, turn the pressure dial all the way anti clockwise. The
watermaker will stop making water and will automatically start the flushing process. The
green and orange lights on the control panel will turn on, which indicates that flushing is in
process. This should take 30 seconds and will stop automatically. The green and orange
lights will shut off and the only indicator will be the blue flashing light on the ON/OFF
button, to remind you to shut the watermaker OFF.
The automatic flush is a better way to flush the system since it’s not only flushes the sea
water out, it also back wash the pre-filter and dumps all the dirt and debris that
accumulated in the filter’s housing, back to the sea, through the sea water intake.
DON’T FORGET!!!
After each system flushing, before using the watermaker you need to:
1. Make sure the pressure dial is turned all the way anti clockwise.
2. Turn the watermaker ON and let it run with no pressure for 1 minute until the red
alarm light comes on. This is the time needed for the sea water to replace all the
fresh water that are in the system, before running pressurized sea water through
the membranes.
RUNNING FRESH WATER IN HIGH PRESSURE THROUGH THE MEMBRANES WILL
DAMAGE THE MEMBRANES!!!
