Replacement of membrane
Warning!
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.
Attention!
To avoid that the new membrane dries out, it may only be removed from the
plastic packaging just before commissioning the plant. The
manufacturer's
label on the membrane must not be removed .
Before installing a new membrane, the accompanying rubber V-cup
seal must be mounted on the side of the planned sea water entry.
(Depending on the manufacturer, the ring could already be mounted.)
In doing so, the open side of the V-ring must point toward the sea
water entry side.
For easy installation, all sealing rings and membrane connectors
should be greased with a light coating of glycerine or Vaseline.
Note!
The product water connection can be located on any side of the pressure tube
and is independent of the flow direction seawater.
Demounting the membrane:
For demounting the membranes, screw off the screws M6x20 at both ends of the AQUATEC pressure
vessel. (Screw tightening torque for the holding clips 3 Nm). Then take off the stainless-steel holding
clamps. Push the end caps in a little before pulling them out to loosen the possibly stuck O-rings.
Thereafter, pull the end caps out of the pressure pipe with a slight pull at the stainless steel-fittings of
the pressure hoses and slightly sidewise movements.
The membrane has to be shoved out of the pressure pipe in flow direction of sea water, because the
dihedral rubber V-ring of the membrane prevents lateral movements against the flow direction.
According to this, during assembly, the membrane has to be shoved into the pressure pipe in flow
direction. When mounted, necessarily watch the O-rings to avoid damage. Before installation of the
membranes, first fit the end cap on the side of the concentrate in order to thereupon shove the
membrane against this cap.
