  • Page 5 Introduction The principle of reverse osmosis (RO) In natural sciences and technology, osmosis is perceived as the directed migration of molecules through a semi permeable membrane. The chemical and physical structure of the membrane determines which molecules are able to pass and which are not. For this reason, it is called semi-permeable, which means as much as halfway or partial permeability.
  • Page 6 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.

    Switch off the system, fresh water flush 1) Open the pressure control valve until the plant runs without pressure. 2) Run the Aquatec several minutes to remove the concentrated salt from the membranes. 3) Turn three-way valve (no. 2) to position test-outlet. 4) Switch off the high-pressure pump first and then the feed pump.

A level teaspoon corresponds to 5 grams Biocide (Natriummetabisulfit). DD 500 Max. 37,5 gr. Biocide Note: For preservation times of approx. 4 months, half of the chemical is sufficient.
  • Page 10 Long term preservation (mothballing) of the plant 2 A standard 1/2” hose can be used for this purpose, which should be fitted onto the HP threaded connector of the high pressure pump to drain the water out into a bucket. Then drain the all the water from the pump, which is important if there is a risk of frost, if possible it is also preferable to blow pressurized air through it in the direction of flow, for this purpose remove both hoses.

    Membrane cleaning. Working pressure 0 bar!!! Description: When the fresh water production decreases more than 15 %, the membrane should be cleaned chemically. Caution: Cleaning chemical no. 1 is alkaline and cleaning chemical no. 2 is an acid. Please consider the hazard notes on the canisters.

  • Page 13 Installation guide page 1 Caution: Hose connections below the water line should secured with 2 hose clamps. All hose clamps must checked time to time and tighten if need. During assembly of the hose nozzles and fittings, few windings of Teflon-tape have to be wrapped around the screw thread against screw direction as tightly as possible.
  • Page 14 Installation guide page 2 Filter housing For a good sealing of the filter housing, please lubricate the O-rings in the filter bowls with the included acid-free silicone grease. Mount the filter housing at an easily accessible place. Connect the filter inlet with the outlet of the feed pump and the filter outlet via PVC hose with the high-pressure pump.
  • Page 15 Installation guide page 3 Fresh water flushing system Mount the filter housing for the charcoal filter at an easily accessible place between the fresh water pressure system and the prefilter housing. Install the hose connections corresponding to the flow diagram. Attention: The maximum pressure in the inlet (seawater, fresh water flushing) must not exceed 2.5 bar.
  • Page 16 Installation guide page 4 High-pressure hose, to be cut into two parts according to your needs. To allow a flexible assembly, the high-pressure hose is provided as one piece of 4 meters (13.1 feet) with a V4A high-pressure fitting at both ends. Please fit the required lengths accurately before cutting the hose.
  • Page 17 Installation guide page 5 Attention: Secure the high-pressure connection fittings in the plastic end caps of the pressure pipe against twisting with a 19 mm open-ended wrench (not necessary on end caps fittings secured with metal strips) and tighten the union nut of the high-pressure hose with a 17 mm open-ended wrench with approx.
  • Page 18 Installation guide page 6 Tank for membrane conservation and cleaning The tank has to be mounted above the system to ensure the flow to the plant. If this is not possible, an additional feed pump has to be installed. The tank can be fastened to any plane surface with the help of the enclosed webbing and the plastic long eyelets.

Important: Check oil level and condition Dipstick full screwed of the oil of the high-pressure pump into crankcase daily. Öl level If condensation occurs (continuous operation, warm environment) change oil immediate.
  • Page 21 Replacement of membrane Attention !!! The membrane is preserved with a chemical. During unpacking and inserting, please wear protective gloves for your own safety. On contact with the preservative liquid, the affected skin areas have to be rinsed thoroughly with water. Important: To avoid that the new membrane dries out, it may only be removed from the plastic packaging just before commissioning the plant.
