IV. Connecting Tubing Using Compression Fittings
Compression fittings are used in both the Kitchen Diverter Valve & the Washing Machine Adaptor. Rather
than an o-ring seal with teeth (like the quick connect fittings), compression fittings crimp the tubing around a
stem to seal the water, the compression ring then prevents the tubing from being removed. Inserting the
tubing over the stem of the compression fitting can sometimes be difficult as the tubing needs to stretch
over it, if you are having trouble, you can run the end of the tubing under warm water (not hot) to help
soften the tubing. The below diagram demonstrates how this it to be installed.
System Installation/Start-Up
I. Pre-Flushing
As previously mentioned above, the portable units are assembled with the inlet filter disconnected from the
membrane to allow pre-flushing. To pre-flush the inlet filter, firstly plug the tubing joining the inlet valve to
the inlet port of the system. Turn on the inlet feed water to maximum, this will flush the pre filter at high
pressure to clear out any carbon fines. The water will run black and cloudy for a few moments, shut off the
tap and give the filter a shake (To stir up the media) and repeat a few times until the water runs consistently
clear. You can also connect your feed water (unfiltered) straight into the inlet of the GT6-18LS filter to also
flush this filter with mains pressure.
Note: When flushing out the system on start-up (below) close the DI filter valve and open the GT6-18LS
filter valve so the water is flushed through that rather than the DI.
II. Tubing Connections
Following the above flushing process, check your systems fittings and tubing to ensure everything looks
sound; there are no kinks, damaged fittings or tubing that is not plugged in. Connect the inlet filter to the
inlet side of the membrane (screw cap end). You should have 3 lengths of tubing that are only connected at
one end, these lines will be your drain line (waste water) which is connected to the inline valve marked
‘Drain Line’ of Flow 200/300/400. The other line will be the drinking water line or Aquarium water line which
is the finished product water. Once all tubes are accounted for and everything is in order, start-up can
commence.
III. Initial Start-Up
For the first run, it is best to bypass your DI Filter (GT6-22) while flushing the membrane. Allow both the
membrane outlet lines to flow to waste into a sink. Turn on the inlet water to the system on full
pressure/flow. The Drain line will begin to flow almost straight away which is normal, you may notice some
slight discolouration. The membrane water line will take longer to begin flowing, this is due to the water
slowly making its way through the membrane.
