j You must read and understand the contents of this manual
before installing or operating your water refiner. Personal
injury or property damage could result if you fail to follow
instructions in this manual.
j This system and its installation must comply with state and
local regulations. Check with your local public works
department for plumbing and sanitation codes. Local codes
should be followed In the event the codes conflict with any
content in this manual.
j For installations in Massachusetts, Massachusetts Plumbing
Code 248 CMR shall be adhered to. Consult your licensed
plumber for installation of this system.
j This water refiner must be operated on pressures
between 30 psi to 125 psi. If the water pressure is higher than
125 PSI, use a pressure reducing valve in the water supply
line to the refiner.
j This unit must be operated at temperatures between 40°F and
110°F (4°C - 43°C).
j Do not use this water refiner on hot water supplies.
j Do not install this unit where it may be exposed to wet
weather, direct sunlight, or temperatures outside of the range
specified above.
j Apply provided NSF certified lubricant to all o-rings during
installation. Do not use pinched or damaged o-rings during
installation.
j Refiners are exposed to high levels of iron, manganese,
sulfur, and sediments. Damage to pistons, seals, and or
spacers within the control valve are not covered in this
warranty due to the harsh environment.
j It is recommended to annually inspect and service the control
valve. Frequent cleaning and or replacement of piston, seals,
and or spacers may be necessary depending on how harsh the
conditions are.
j Do not use water that is microbiologically unsafe without
adequate disinfection before or after this system.
j This publication is based on information available when
approved for printing. Continuing design refinement could
cause changes that may not be included in this publication.

Certified by IAPMO R&T according to NSF/ANSI 44
for effective reduction of hardness (calcium and
magnesium) as verified and substantiated by test data.
This product is efficiency rated according to NSF/ANSI 44. The stated efficiencies are valid only at the specified sodium dosages and
maximum service flow rate.
These refiners conform to NSF/ANSI 44 for the specific performance claims as verified and substantiated by test data. These models
are efficiency rated. The efficiency rating is valid only at the stated sodium dose and maximum service flow rate. They have a demand
initiated regeneration (D.I.R.) feature that complies with specific performance specifications intended to minimize the amount of
regenerant brine and water used in their operation. These refiners have a rated refiner efficiency of not less than 3350 grains of total
hardness exchange per pound of sodium (based on sodium chloride) and shall not deliver more sodium than their listed ratings. The
rated sodium efficiency is measured by laboratory tests described in NSF/ANSI Standard 44. These tests represent the maximum
possible efficiency that the systems can achieve. Operational efficiency is the actual efficiency after the system has been installed. It is
typically less than the efficiency due to individual application factors including water hardness, water usage, and other contaminants
that reduce the refiner’s capacity. These systems are not intended for use with water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after the system. For best results, use plain, white block sodium. Refer to Installation/
operation manual and warranty for further details on installation, parts and service, maintenance and further restrictions or limitations
to the use of the product.

PLUMBING
You must solder all joints near
the valve before connecting
any piping to the valve. Always
leave at least 6” (152 mm)
between the valve and joints
when soldering pipes that are
connected to the valve. Failure
to do this could cause damage
to the valve.
G) Attach Brine Tubing to the Brine Line
of the Valve
Insert
Sleeve
inside the
Tubing
Brine Line
F) For installation
of brine tank at
the installation
site, pull the
other end of
the brine tube
from the hole on
the brine tank.
The completed
assembly is
shown on right.
A) Attach the four brine grid legs to grid
plate. The legs will snap on to the
tabs of the sodium plate making a
“click” sound.
D) Insert the nut and hose barb in to the
brine tube as shown below.
INSERT DRAIN
HOSE BARB
ASSEMBLE BRINE TANK
B) Insert the brine
well assembly
inside the grid
plate as shown
below.
C) Drop the brine grid with brine well
inside the brine tank. Position the
nut fitting so it faces the hole on the
brine tank. Press the grid evenly
inside the brine tank until the brine
grid legs touches the bottom of the
brine tank.
The hole in the brine tank
should line up with the brine
line as shown .
E) Insert the tube in the float assembly
elbow. Hand tighten the nut. In many
cases the brine line come installed from
the factory. Leave the other end of the
brine line tube inside the brine tank.
