Operating instructions
Attention
Do not operate your water maker with unpurified seawater (oil, chlorine or other
chemicals).
The R.O. membranes are conserved with a dissolution that, when ingested, can
cause irritations of the gastrointestinal tract. For that reason, the product water must
not be consumed within the first 30 minutes of operating time, beforehand it has to be
drained over the test-outlet. This applies accordingly after temporary shutdown or
cleaning of the membranes with the cleaning chemicals.
Placing into operation
Check oil level and condition of the oil of the high-pressure pump.
1) Open the seawater intake valve.
2) The pressure control valve in the control panel has to be fully opened by turning
counter clockwise. Attention : Never start your Aquatec with closed pressure
control valve! Starting with a closed valve destroys the pressure reading and
possibly essential parts of the equipment. An open pressure control valve can be
seen when the first two threads of the valve body becoming visible by turning the
pressure control wheel
.
3) Turn three-way valve (4) according to the flow diagram to position fresh water
production. Turn three-way valve (2) to position test-outlet.
4) Switch on the feed pump. De-aerate the plant if necessary.
5) Switch on the high-pressure pump. De-aerate the system and control the drain
water. Inspect the whole system for leakages.
6) Increase the pressure at the pressure control valve by slowly turning it clockwise to
about 30 bar. Let the system work for about 30 seconds. There should not be any
air pockets visible in the system.
7) Increase the pressure stepwise up to the
working pressure (55-60 bar). Test the
product water by tasting (at daily operation, the product water should be salt-free
after about 60 seconds). By shifting the three-way valve no. 2, the product water is
fed into the fresh water tank.
Attention: If Aquatec is run in brackish water or in low-salt water (e.g. Baltic Sea), the
fresh water production must not exceed the displayed value! In this case, increase
the pressure under continuous observation of the produced amount of water until the
normal level of fresh water production is reached.
