7.2 Facing the iSpring logo up front, the pre-filter 1st stage is located on the right hand side. Connect the
tubing Feed Water Adapter (AFW) (point A) to the elbow fitting (point B).
7.3 Connect the Flow Restrictor (point C) , which is a 3-inch long cylinder with a FLOW sign laying beside the
membrane housing, to the Drain Saddle (point D) with the
7.4 On the right side of the Post Carbon Filter (FT15 5
Valve (point F) with the YELLOW tubing.
7.5 * Model without UV/AK/DI: at left end of FT15, insert the
fitting.
* Model with UV/AK/DI: RO water flows out of point G at FT15 and flows into the left end of next stage.
So the
BLUE
tubing (links to RO faucet) should be connected at the final end of the last stage, which could
be the UV/AK/DI filter.
7.6 Connect the other end of the
7.7 You may organize the tubings, but make sure to leave enough length so the filter system can be moved freely
in and out of the cabinet when replacing filters.
7.8 You may hang the system using two 10 x 1-1/4 Phillips Flat Wood Screws. This will
make replacing filter cartridges easier.
Step 8: System Start Up (model specific sub-steps are marked with * )
* If your model has a UV stage, do not plug in power until the system is fully flushed
8.1 Make sure that all tubings are not kinked. Turn Tank Shut-off Valve OFF (cross). Prepare a bath towel to
catch any water leak.
8.2 To avoid the residual carbon in the first three stages from getting into the RO membrane, the tubing to the
inlet of the RO membrane housing cap was left disconnected. Flush the first three stages into a bucket until
the water turns clear, and re-connect the tubing to the RO membrane. (You may do this whenever you change
the first three stages).
8.3 Turn on (inline) Feed Water Adapter valve (AFW), and then slowly turn on the Cold Water Supply Valve
(CWSV) and check for leaks. The top 3 causes of leaks are 1) the tubing was not fully inserted into the
quick-connect fitting. 2) the O-ring was not in place or kinked. 3) the Housing/Cap was not tightened up or
off threads.
8.4 * Plug in booster pump power if your model has one.
8.5 Within 5 minutes, RO water should start dripping. Let it run for at least 10 minutes. This flushes the system
except the tank. Water is black due to loose carbon from new carbon filters (step 8.2 could be taken to
expedite the flush). It will turn clear with some air bubble.
