HOW TO CUT AND CONNECT
THE TUBES
Your Reverse Osmosis Water
System includes push-in fit-
tings for quick tubing
connection.
Review the following
instructions
before
connecting
the tubes in the next step.
Cut tubes to length
1. Use a sharp cutter
or knife to cut the end of tubing.
Always
cut the tubing
square. See Figure 17.
2. Inspect the end (about
1") of the tubing
to be sure there
are no nicks, scratches
or other rough spots. If needed,
cut the tubing
again. See Figure 17.
NOTE:
Tubing lengths should allow for the removal
of
the assembly
from the hanger washers for servicing.
If
tubing
lengths are shortened
for neater appearance,
it
may be necessary
to keep the assembly
on the hanger
washers for service.
Connect tubes
NOTE: Remove protective
foam plugs before connecting
tubes (See Fig. 16). Discard foam plugs.
1. Push tubing through
collet, until it engages
the o-ring.
See Figure 18A. Continue
pushing until the tube bottoms
out against
the back of the fitting.
See Figure 18B. A
common
mistake
is to stop pushing when the tube
engages
the o-ring. This will lead to future
leaks. When
a 1/4" tube is fully engaged,
11/16" of the tube has
entered
the fitting.
When
a 3/8"
tube is fully engaged,
3/4"
of the tube has entered
the fitting.
See Figures
18A & 18B.
2. If using tubing other than tubing
supplied
with the sys-
tem, be sure it is of high quality,
exact size and round-
ness with a smooth surface.
To Disconnect Tubes
1. Push the collet inward
with a finger tip. See Figure 20.
2. Continue
holding
collet inward
while pulling
the tubing
out. See Figure 20.
