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
Important:
Check oil level and condition of the oil of the high-pressure pump daily.
1) Open the seawater intake valve (no.10).
2) The pressure control valve (no.5) 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
.
(see picture left )
3) Turn three-way valve (No. 4) according to the flow diagram to position fresh water
production. Turn three-way valve (No. 2) to position test-outlet.
4) Switch on the feed pump. De-aerate the plant if necessary. The gauge feed water
(option) must show positive pressure. De-aerate the pre filter/ system and control
the drain water To prefill the system, a short fresh water flush via the onboard
pressure water pump can be useful.
5) Switch on the high-pressure pump. 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
maximum
working pressure (55 – 60
bar, 800 - 850 psi).
Test the product water by tasting from the test outlet (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:
Never turn the pressure regulation knob completely out while the system is running. The
pressure pushes out the parts inside, which can result in injury and loss.
Note:
If Aquatec is run in brackish water or in low-salt water, the fresh water production must not
exceed the displayed value! In this case, regulate the pressure under continuous observation
of the produced amount of water until the normal level of fresh water production is reached.
(e.g. Baltic Sea about
35 bar or 490 psi
)
