Assemble main RO system
7. Remove all packaging and plastic wrapping/seals from filters.
Do
not include the membrane(s) in this step.
Connect housings to RO system by hand and then use spanner
provided to completely tighten. From right to left (closest to inlet):

Connect system
Determine length of tubing needed between RO system and mains
water supply and remove red stopper on unit. Connect tubing from
cold water supply, drain clamp and water outlet to RO system by
removing the coloured stoppers and inserting tubing into the
connections listed below:
Mark 1 (WHITE stopper)
– Cold water supply to RO system
Mark 2 (BLACK stopper)
– Wastewater to drain
Mark 3 (YELLOW stopper)
– Do not remove unless you are
connecting to a pressurised storage tank.
Mark 4 (BLUE stopper)
– Last stage on RO system to water outlet.
Check all tubing is secure by pulling back on tubing, remembering to
always remove collet clips before inserting tubing.
System Flushing
–
It is very important to flush the RO system through in 2 stages to protect
the membrane(s) and to ensure optimum performance for your unit.
Flushing the unit releases any carbon fines, dust, air etc from the pre
and post filters which may have been present at the manufacturing
process.
By flushing the unit in 2 stages this stops the membrane from getting
clogged or a reduction in flow as the pre and post filters have already
been flushed.
