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.
Note: This process can also be done to the other inline filters in the system, for example the alkaline filters.
It is recommended (but not required) to remove each filter (1 at a time so you don’t lose track of filter
position) and repeat the above step to clear the fines out of each filter. Flushing filters directly off the mains
pressure will greatly decrease the flushing time at the initial start-up stage.
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 2 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 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, allow both the waste and drinking water 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 drinking water line will take longer to begin flowing,
this is due to the water slowly making its way through the membrane filling the filter cannisters as it goes. 3
Stage systems generally start flowing within a few minutes where the 6 stage units can take over 5 minutes
