Your new CFS6000 Series water filter system is designed
to be installed on the cold water line. The CFS6000 Series
features its own automatic shut-off, thereby eliminating
the need for a shut-off valve on the incoming supply line.
Note: It is advisable to install a drain valve after the system
for routine maintenance. A flush kit can be purchased separately if a drain valve is not desired. See the CUNO

Your new CFS7000 Series water filter system is designed
to be installed on the cold water line. This filter system
requires a shut-off valve installed on the inlet water line,
preferably near the filter for convenience.
INSTALLATION PRECAUTIONS
• The filter
must
be installed with the inlet and outlet as labeled. Make sure not to reverse connections.
•
Do not
install on hot water line. Maximum temperature allowed is 100°F (38°C).
•
Do not
install on line pressure above 125 psi (862 kPa).
•
Do not
use wicking or sealer for fitting connections into head of filter. Use Teflon®Tape for connections.
•
Do not
use torch or other high temperature sources near filter system.
•
Do not
install near electric wires or water pipes which will be in the path of drill when selecting the position to
mount the bracket.
•
Do not
install in direct sunlight.
• Protect from freezing. Drain filter when room temperature drops below 40°F (4.4°C).
• Allow minimum of 2” (5 cm) clear space under filter to facilitate cartridge change.
• Mount filter in such a position as to prevent it from being struck by other items.
• Installation must comply with existing state or local plumbing codes.

Procedure for Installing CFS6000 and CFS7000 Series Filter Systems
Before starting, close shut-off valve on cold water line
CFS6000 series and CFS7000 series - Bracket can be installed either up or down.
Step 1. Attach the mounting bracket to the filter head with the two mounting screws (provided).
Step 2. Install filter cartridge into filter head. (See Replacement Cartridge Change Instructions). Position filter
bracket by holding it up against the mounting surface. Allow at least 2” (5 cm) of clearance below the
cartridge to facilitate cartridge removal. Mark the mounting hole locations onto the mounting surface.
Secure bracket to mounting surface using appropriate mounting hardware. The unit may be mounted either
vertically or horizontally.
Step 3. CFS6000 Series - The inlet/outlet connections are 3/8” female pipe threads. Appropriate fittings/piping/
tubing tools vary by requirements of each installation. The CFS6000 Series contains an internal shut-off
valve in the filter head, therefore, no external shut-off valve is required. Be sure to always use Teflon
®
tape
to seal tapered threads.
Important: Do not use acid base pipe sealers or wicking on plastic filter head.
CFS7000 Series - The inlet/outlet connections are 3/8” female pipe threads. Appropriate fittings/piping/ tubing
tools vary by requirements of each installation. Shut-off valves should be installed on both the inlet and outlet
water lines. Be sure to always use Teflon®Tape to seal tapered threads.
Important: Do not use acid base pipe
sealers or wicking on plastic filter head.
Step 4. Make any required connections and pressurize system to check for leaks. If none are apparent, flush new
cartridge for a minimum of five minutes to remove any trapped air or carbon fines. The filter system is now
ready for service.
