Procedure for Installing CS-400 Series Water Filtration Systems
Before starting, close shut-off valve on cold water line.
Step 1.
The Mounting Bracket may be installed with the back of the bracket in the up or down position
Screws may be used to attach the bracket to the desired surface or the industrial double-sided tape
strip can be cut in half and used to mound the bracket. (Be sure that both the surface of the bracket
and the mounting surface are clean. Be sure to allow at least 2” (5 cm) of clearance below the unit.)
Step 2.
The filter must be installed with inlet and outlet ports as labeled. Make sure not to reverse the con-
nections.
IMPORTANT:
ON TOP OF THE FILTER HEAD you will see the numbers 1, 2, and 3 molded
into the plastic head.
Port 3 is labeled inlet.
Port 1 is labeled outlet.
Port 2 is not an option and is not threaded for fittings
The shut off valve should be located in line somewhere between the incoming water line and the inlet fitting.
Step 3.
Attach the head to the bracket with the screws provided. All four screws can be used, or two can be
used to mount the bracket to the desired surface.
Step 4.
Install cartridge, (see Cartridge Change instructions on next page and follow Steps 3 and 4) and
make any required connections. Pressurize the system and check for leaks. Flush system in accor-
dance with Performance Data Sheet. Water may run cloudy but will quickly clear.
WARNING
To reduce the risk associated with hazardous voltage:
• Do not install near electric wiring or piping which may be in path of a drilling tool when selecting the position to moun
t the
filter bracket.
IMPORTANT NOTES
• Note adjacent equipment which may interfere with system fastening screws.
