Troubleshooting
Product amount of water too low:
Cause
Membrane is blocked or defect.
Temperature seawater lower than 25 ° Celsius.
Salinity seawater higher than 35,000 ppm.
Reduced fresh water flow through blocked or dirty filters
Insufficient fresh water rinsing after every use.
Insufficient chlorine separation by the charcoal filter, assuming chlorine is or was present
in the rinsing tank, chemicals or oil sucked in.
HP pump: dirty or defective valve.
HP pumps insufficient performance.
Under voltage in the electrical system.
Control of the HP pump’s performance.
Current consumption according to specification too low?
Cause:
Probably dirty or defective valve.
Current consumption consistent with specification OK?
Recommendation: accurate test of the HP pump output:
Instruction for testing the flow (liters/minute) of the HP pump.
1) Place the plant into operation.
2) Adjust the working pressure.
3) Turn the 3-way valve No: 4 to operate toward the 10-liter conservation tank.
4) Using a stop-watch, measure the time to fill the 10 liter tank. In order to avoid an
overflow, strictly reposition the valve to the board setting shortly before the tank is full.
5) In addition, collect the amount of product water in the same period of time over the
test outlet in a vessel and add it.
HP pump performance in liters per minute at 55 bar working pressure:
DD 500, 3-3.5 liter / minute
