Step 30
Connect the loose green tubing to the adapta valve (installed at steps 12 and 13).
30a
Insert the green tube into the 1/4” connector on the adapta valve. The
tubing must be fully inserted in the connector. The 1/4” tubing should
be inserted about 5/8”. Push the tubing through the small hole in the
connector until you feel resistance. At this point, the tubing is not fully
inserted. Then push firmly until the tubing is inserted as far as it will go.
DO NOT CUT GREEN TUBING.
30b
For the purpose of flushing the MP750SI Final Filter, insert the other
end of the green tube into the 1/4” inlet connector of MP750SI.
Step 31a
To flush the Final Filter, turn on cold water supply by turning the handle
on the valve.
31b
Then open the RO faucet by lowering the operating lever (handle) and
lock in the down position.
31c
Allow water to flow through the MP750SI Final Filter for about 5 minutes
so that all air can escape.
31d
Close the RO faucet and check for leaks.
- Check the V-Band to confirm that it is secured evenly around the housing top and bottom.
- Hand-tighten the black knob on the V-Band until it is as tight possible.
31e
Allow water to again run through the unit to waste for approximately 20 minutes to charge
the carbon and flush out loose carbon particles.
31f
Shut off the water to the faucet and water supply at the valve.
31g
Disconnect the green tube from the inlet port of the MP750SI. Instructions on connect-
ing the green tube to the RO Pre-Filter module are provided on page 11, step 35. Wait until
you get to that step to make that connection.
NOW YOU ARE READY TO CONNECT THE FINAL FILTER TO THE TANK.
Step 32a
To connect the MP750SI Final Filter to the Tank, use about 12” TO 18” of the 1/4” clear
tubing. Make sure that both ends are cut straight.
32b
Insert one end of the clear tube into the 1/4” inlet connector as far as it will go. The
tubing must be fully inserted in the connector. The 1/4” tubing should be inserted about
5/8”. Push the tubing through the small hole in the connector until you feel resistance. At
this point, the tubing is not fully inserted. Then push firmly until the tubing is inserted as f
far as it will go.
NOTE:
Retain the remaining clear tubing for flushing the RO pre-filters at page 11, step 36 when
you get to that step.
