Connecting The Faucet; Installing The Cartridge; Putting The Filter Into Operation - Culligan US-EZ Installation And Operating Instructions Manual

NOTE: Filter head should be mounted in vertical position, use mounting bracket as a template to
mark screw locations. Mount filter head in marked location using screws.
Filter head should be mounted on a stud or firm surface. The mounting bracket will
CAUTION:
support the weight of the filter and help prevent strain on the cold water line.
B) If filter assembly is mounted on a side wall next to drawers, remove drawers. Cabinet wall may
be too thin to support filter assembly. We recommend that a 3" x 3" x 1/2" wood block be used
on the back side of the cabinet to allow the screws to penetrate through the cabinet and into the
wood block. This will allow the filter assembly to be fully supported. Using the filter head assembly
as a template, drill two 1/4-inch holes in the side wall. Position the block of wood behind these
two holes and drill two 1/8-inch holes into the block. Use the two screws provided to mount filter
assembly head to side wall and on the block of wood.
5. Connecting the Supply Adapter
and Inlet of Filter
A) Determine the length of plastic tubing needed to connect the inlet (left) side of the filter with the
supply adapter. Be sure to allow enough tubing to prevent kinking and cut the tubing squarely.
Place a mark 5/8-inch (16 mm) from both ends of the tubing.
B)
Wet tubing with water and insert into the supply adapter, 5/8-inch (16 mm) until mark is flush
with fitting.
C) Wet tubing with water and insert into the filter inlet, 5/8-inch (16 mm) until mark is flush with
fitting.
NOTE: Disconnecting the Tubing from the Quick-Connect Fittings. Routine maintenance and
cartridge replacement will not require that you disconnect the tubing from the filter system;
however, tubing may be quickly and easily removed from the fitting if necessary. First, turn off the
water supply to the filter. Open faucet, then press in the grey collar around the fitting while pulling
the tubing with your other hand.

6. Connecting the Faucet

Do not over-tighten compression nut. Use caution not to bend or crimp tubes
CAUTION:
when securing.
A) Determine the length of plastic tubing needed to connect the outlet (right) side of the filter with
the faucet. Cut the tubing squarely.
Do not bend or crimp tube when inserting.
CAUTION:
B) Slide plastic compression nut
oriented properly, then place insert
C) Push the tubing firmly into the end of the faucet stem
onto threads until secure. Then tighten approximately 1/2 turn with a wrench.

7. Installing the Cartridge

Hold cartridge from the bottom when installing or changing the cartridge. Use caution not to scrape
knuckles on bracket when locking the cartridge into place. Line up the arrow on the cartridge with unlocked
padlock symbol on head. Insert cartridge and turn arrow to locked padlock symbol. See the diagrams in
Filter Cartridge Replacement on page 4.

8. Putting the Filter into Operation

A) Turn on water supply valve. Check for leaks. If it leaks, see Troubleshooting.
B) Rotate handle of drinking water faucet counter-clockwise to "on" position. Allow water to run for
10 minutes to flush air and carbon fines (very fine black powder).
C) Check for leaks before leaving installation. If it leaks, see Troubleshooting.
