Food Service CFS6000 and CFS7000 Series Water Filter Systems
Automatic Shut-off • Particulate and Chlorine Reduction •
Optional Scale/Corrosion and Cyst Reduction
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 sep-
arately if a drain valve is not desired. See the CUNO®Food
Service Price List for part number and price.
Sanitary Quick Change (SQC) • Particulate and Chlorine
Reduction • Optional Scale/Corrosion and Cyst Reduction
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.
•
Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection
before or after the system.

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.

Replacement Cartridge Change Instructions for CFS6000 and CFS7000 Series
Replace cartridge when there is a decrease in water flow or when objectionable taste and/or odors return. It is
recommended that the cartridge be changed at least every six months. Always have spare cartridges on hand.
CFS6000 Series
Step 1. Turn cartridge slowly, approximately 90° to the left until it hits a stop and the slot on the cartridge lines up
with the word “Off” on the head. At this position, the inlet and outlet ports have been closed and the filter’s
internal pressure has been relieved.
Step 2. Pull used cartridge straight down and discard.
Note: There is a small amount of residual water drainage
after pressure is relieved and during cartridge removal.
Step 3. Push new cartridge into head with slot on cartridge in line with the word “Off” on head. Top surface of
cartridge will become flush with bottom of head when fully engaged. Turn cartridge approximately 90°
to the right until it hits a stop. Flush new cartridge for a minimum of five minutes to remove any trapped air
or carbon fines. The system is now ready for service.
CFS7000 Series
Step 1. Close shut-off valves on inlet and outlet lines to filter head.
Step 2. Lift red knob upward and hold.
Step 3. While holding red knob up, turn cartridge to the left while grasping cartridge securely. Pull cartridge straight
down and discard.
Note: There is a small amount of residual water drainage after pressure is relieved
and during cartridge removal.
Step 4. Align tabs of cartridge with head and insert new cartridge into head. Turn cartridge to the right until a
clicking sound indicates the cartridge is properly engaged.
Step 5. Place inlet and outlet shut-off valves in operating positions.
Step 6. Flush new cartridge for a minimum of five minutes to remove trapped air and carbon fines. The system is now
ready for service.
