Attn: Installer, Important Safety Precautions: Read before attempting installation!!!! Do not
discard these instructions, they contain important operating instructions. Please give to user
upon completion of installation!

Do not expose fittings and valves to excessive heat when connecting water supplies. Seals and gaskets could be damaged by high heat
due to soldering with a torch.

It is recommended that water hammer arrestors are used when plumbing system experiences water hammer.
MAXIMUM WATER PRESSURE FOR THE SYSTEM IS 100 PSI.

MAXIMUM WATER TEMPERATURE IS 90° F.
Do not expose filter cartridge to solvents, harsh cleaning agents or chemicals other than water and a mild dishwashing detergent. The

plastic will weaken and crack as a result.

DO NOT USE WRENCH TO TIGHTEN FILTER CARTRIDGE AFTER FILTER CHANGE. IF LEAK OCCURS REPLACE O-RING.
WRENCH TIGHTENING CARTRIDGE MAY CAUSE HEAD TO STRESS CRACK.

DO NOT INSTALL FILTER SYSTEMS ABOVE ELECTRICAL EQUIPMENT.
DO NOT INSTALL THE FXWS-12B WHERE FILTERS ARE NOT ACCESSIBLE OR EXPOSED TO HEAT.
DO NOT OVERTIGHTEN FITTINGS INTO PLASTIC HOUSINGS, FITTINGS OR MANIFOLDS.
For use on potable water supplies only! The FXWS-12B is not intended for use on water that is microbiologically

unsafe.
Specifications:

Inlet/Outlet Connections: 3/4" female NPT.
Rated Capacity: 4500 grains.
Overall Dimensions: 14.25" wide x 23" high (allow +3" for removing sump for changes) x 8" deep.

This system is ideal for removing hardness from water for use in Espresso Machines, Steam Cabinets or Tables and
other equipment where hardness scaling is a problem.

Before Installation:

1. Flush water supply lines to avoid plugging filters with installation debris and resin from solder joints.

2. Check water pressure for requirements of equipment that uses water.

3. Determine site of installation, space required, and mounting hardware required. Wall must be structurally sound for mounting water
system. Mount into studs whenever possible. Allow enough clearance below filter housings for changing. FXWS-12B requires at
least 3 inches.

4. Use 2 wraps of Teflon tape for sealing pipe joints. Do not overtighten fittings, this may cause cracking.

5. Read through instructions before installing water system.

6. Obtain appropriate adapters to go from 3/4" fpt to supply and equipment.

7. Use hardness test strips included with the FXWS-12B to test the hardness of the water before and after the FXWS-12B and document
below.

Hardness conversion: 1 grain per gallon equals 17.1 ppm or mg/l. e.g. 10 grains of hardness is equal to 171 mg/l of hardness.

The formula to determine cartridge life span is:

Grains capacity of filter/grains per gallon = gallons softened

An Example:
If the FXWS-12B was installed in a system with feedwater that contains 10 grains of hardness, the expected life span would be: 4500
grains /10 grains = 450 gallons of softened water. The higher the grains per gallon the lower the capacity of the cartridge.

Caution: If used on a espresso machine that has an automatic cleaning cycle the amount of water used daily must be subtracted from the
total gallon throughput. In addition, these figures are the calculated capacity. In cases where the water has above normal sediment or
chlorine, the rated capacity of the cartridge may be reduced. To achieve the maximum protection for the equipment it is recommended
that the hardness be monitored until a standard can be established.
