MP750SI Final Filter Installation -
Item #1 on page 21
The filter cartridge is shipped outside the unit housing to protect your filter cartridge and housing from
damage during shipping. Be sure to insert the filter cartridge into the Final Filter housing before installing
it. Complete, detailed instructions are provided with the filter cartridge.
Step 25 Gather the parts needed to install the MP750SI Final Filter:
1 housing 1 CB6 filter 2 1/4" male connector (MC720)
Step 26a Connect the 1/4" male connector to the OUTLET opening on the unit hous-
ing by turning clockwise. Tighten by hand and then give one to two extra
turns with a wrench.
26b Connect 1/4" male connector to the INLET opening on the unit housing by
turning clockwise. Tighten by hand and then give one to two extra turns
with a wrench.
Step 27 Remove plastic wrapper and instruction wrapper from the filter cartridge.
With the Final Filter housing in an upright position, open the unit by
unscrewing the knob on the Locking V-Band. Spread it apart and remove
the Locking V-Band.
Step 28a Separate the unit, leaving the black O-ring in place.
28b Screw the filter cartridge into the housing top by turning the cartridge until firm. DO NOT
OVERTIGHTEN.
28c Connect the housing top with bottom and replace Locking V-Band; replace black knob and
turn until tight. Be sure that the Locking V-Band is fastened tightly by checking it to be sure
that it is secured evenly around the housing top and bottom, and hand-tighten the
black knob until it is as tight as possible.
Step 29a Insert the blue tubing from the faucet into the 1/4” outlet
connector -- insert into the hole in the connector as far as it will go.
Note: First, confirm that the tubing has a straight square cut.
29b The tubing must be fully inserted in the connector fitting; it is
recommended that you measure and mark the end of the tubing that
you are inserting in the fitting to assure that it is inserted as far as it
will go. The 1/4” tubing should be inserted about 7/8”.
29c 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. See measurements above.
