CONNECTING TUBING
Cutting Pipe
• Using a pipe cutter, cut pipe.
• Sand (file) cut ends of pipe to
ensure that they are square
and smooth.
Plastic Tubing
• Cut tube ends square and straight. Do not
deform tube (i.e., cause tube to compress its
diameter so it is no longer round).
• Avoid sharp changes in direction when
routing tubing. Sharp turns cause tubing to
flex and deform, which reduces its flow
capacity and may increase lateral stress on
the fittings, causing leakage.
Illustration 5
Fittings consist of two parts:
a
body and a collet.
Make sure
outer surface of tube is clear of
marks or scratches for a length
equal to twice tube
diameter. This
allows O-ring to seal properly
against tube.
1. Slide compression nut onto the end of
tubing.
2. Connect it to compression adapter and
tighten the compression nut securely.
To Disconnect Tubing
If you need to remove the tube from the quick
fitting, turn off the water and push the collet
(ring of the connector) square against the
fitting. While holding the collet in this position,
pull the tube out. If you have inserted the tube
and need to remove it, be sure to cut 1/2” of
tube from the end before reinserting. This will
help prevent leaking.
• Remove locking clip from collet.
• Push tube through collet into
body until it seats firmly at
bottom of fitting (Fig A, B).
• To remove a tube, push and hold
collet against body while pulling
tube out (Fig C).

CONNECTING SYSTEM TO REFRIGERATOR/APPLIANCE
•
Remove red plugs.
• The filter is to be connected into the 1/4”
OD tube that feeds water to the
refrigerator/appliance. If your refrigerator/
appliance water supply line is 3/8”, use a
3/8” x 1/4” reducer union fitting (see Illus.
1) or consult your plumber.
• Shut off water supply to the refrigerator/
appliance.
• Cut feedwater tube (see Illus. 5).
• Insert feedwater tube from refrigerator/
appliance into the inlet fitting of the water
filter head. Push up to the tube stop and
reattach locking clip.
• Push tube from the water line into inlet

fitting of water filter head. Push up to the tube stop and reattach locking clip.
• Use of quick connect fittings and/or ball valve is optional.
NOTE:
Adjustment to Water Flow
Adjustment to water flow may be needed to prevent pressure buildup if the flow is high or
irregular. Turn the knob on the control valve fitting for adjusting water flow to the filter or to totally
shut off water flow to filter.
• Before using, run water through filter 5-10 minutes.
WATER LEAKS
Your System has been tested before leaving the factory. In the unlikely event of a fault, small leaks
sometimes do occur as a result of incorrect assembly or abuse. The following tips may be helpful:
• Depending on the positioning of the filter and the temperature of the incoming water and air,
condensation on the outside of the filter housing may occur, resulting in a frosted appearance of fine
water droplets on the surface. This does not mean that there is a leak in the system. The remedy is to
either insulate the area around the filter or reposition it.
• Always ensure that the sump is screwed fully into the sump top. This is essential both for the internal seal
and the housing seal.
• In the event of a leak, carefully examine its source. Water from a leak may run along the pipe work (it may
drip or collect some distance from the actual location of the leak).
• Leaks between
base and housing.
Turn off faucet and unscrew base of housing. Check to make sure both
O-rings are clean and undamaged. Replace if necessary. Lubricate O-rings with any non-petroleum oil.
• Leaks at the
quick fittings
are usually due to the tubing not being pushed fully into the fitting. Remove
