be properly seated in the groove below the threads of the housing or
a water leak could occur .

7. Connecting the Faucet to the Drain
NOTE: This is a gravity drain line . Any loops, kinks or sharp bends
must be eliminated before proceeding . Failure to create a straight
line to the drain may result in reject water leaking through the air gap
in the faucet onto the counter top and below the faucet .
A) Align the 3/8" red tubing from the faucet with the compression
nut on the drain clamp . Create as straight a path as possible with
the tubing . Cut the tubing squarely below the nut and remove the
internal and external burrs .
B) Loosen the compression nut two complete turns . Insert the tubing
into the nut until it stops. Tighten with fingers, then tighten 1 to 2
turns with a wrench .

8. Installation of Mounting Screws
A) If system is being installed under the kitchen sink, locate it
on back or right wall . Make sure to allow ample space for
installation (Figure 12). To change the filter cartridges, a minimum
of 1-1/2" of clearance is required underneath the filter housings.
A minimum of 2" of clearance from the left side of the unit is also
required or 5" from the left bracket mounting screw hole .
B) Install mounting screws at least 15" from cabinet floor and 7-1/2"
apart . Leave a 5/16" space between the head of the screw and
the wall to slip bracket onto screws .
NOTE: Each connection fitting on the RO Assembly has a plug that
must be removed before inserting tubing . Push in on the collar and
pull the plug out .
