INSTALLATION
Culligan recommends that Preferred Series Drinking Water
Filters be installed with a faucet dedicated to dispensing only
filtered water. Such a faucet is available from Culligan by
ordering P/N 01-0035-37*. Refer to the plumbing schematic
shown in Figure 1 when completing this type of installation.
Other recommended applications include point-of-use
drinking water coolers, refrigerators, and ice makers.

Check for compliance with state and local laws and regulations.
Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the
system. Systems certified for cyst reduction may be used on
disinfected water that may contain filterable cysts.
This filter system is supplied with fittings which are
designed for use with 1/4 inch O.D. polyethylene tubing:
available from Culligan by ordering P/N 00-4021-84*.
1. Select a location for the filter assembly which:
• Provides a solid mount for the filter head.
• Allows a minimum 2 inches (5 cm) of clearance
under the cartridge.
• Allows space for inlet and outlet water line connections.
Note: The filter must be mounted vertically.
2. Provide an inlet water supply for the filter by tapping
the cold water line. This connection should accom-
modate 1/4 inch O.D. polyethylene tubing and must
comply with state and local laws and regulations.
3. Install the faucet or dispensing device according to the
instructions provided with the device.
4. Refer to Figure 2 to determine the best filter bracket
position to accommodate the water connections.
5. Install the 0.5 gpm flow restrictor fitting into the outlet
port on the filter head using Teflon tape.
Note: The restrictor is built into one of the elbow fittings.
6. Install the remaining 1/4 inch tubing fitting into the fil-
ter head inlet using Teflon tape.
7. Mount the filter head using the screws and washers
provided.
8. Connect the inlet and outlet tubing to the inlet and
outlet fittings of the filter. Double check the water
connections to be sure that water will follow the
direction-of-flow arrow on top of the head; water
supply to inlet fitting, outlet fitting to faucet.
9. Install the filter cartridge as detailed in Figure 3.
10.Flush the cartridge for three minutes to purge the
system of air.
