erage quality, and ensure seamless beverage service.
The sanitary quick change design allows for quick and easy cartridge change-outs and minimizes contamination of

the filtration media.
The CS-900C Series built-in shut off valve allows cartridge change-outs without shutting off the water supply.
Proper fit of the cartridge is assured with a 1/4 turn.
Its compact footprint allows the unit to be installed snugly behind the beverage unit or neatly under a cabinet,

without the need for electrical connections or a drain.
The housing is durable and shatter-resistant, minimizing the potential for leaks.
3/8” vertical connections are compatible with common equipment and tubing installations.
Units are FDA, CFR-21 compliant for use in all food and beverage applications.

To calculate total gallons of softened water:
Capacity of cartridge in Grains divided by Hardness of Incoming Water in Grains per

Gallon = Total Gallons of Softened Water
Example: 1,350 grains/5 grains per gallon hard water = 270 gallons (1,022 liters)

CAUTION: To reduce the risk associated with property damage due to water leakage:
To reduce the risk associated with property damage due to water leakage:

• Read and follow Use Instructions before installation and use of this system.

• Installation and use MUST comply with all state and local plumbing codes..

• Protect from freezing, remove filter cartridge when temperatures are expected to
drop below 40° F (4.4° C).

• Do not install on hot water supply lines. The maximum operating water temper
ture of this filter system is 100°F (38°C).

• Do not install if water pressure exceeds 125 psi (862 kPa). If your water pressure
exceeds 80 psi, you must install a pressure limiting valve. Contact a plumbing
professional if you are uncertain how to check your water pressure.

• Do not install where water hammer conditions may occur. If water hammer
conditions exist you must install a water hammer arrester. Contact a plumbing
professional if you are uncertain how to check for this condition.

• The disposable filter cartridge must be replaced every 6 months, at the rated
capacity or if a noticeable reduction in flow rate occurs.
