Central Water Filtration System Safety
Your safety and the safety of others are very important.
e have provided many safety messages in this manual and on your appliance. Always read and obey all safety
W
messages.
This is the safety alert symbol.
This symbol alerts you to potential hazards that can kill or hurt you and others.
All safety messages will follow the safety alert symbol and either the word “DANGER” or “WARNING”
These words mean:
You can be killed or seriously injured if you don’t
immediately
You can be killed or seriously injured if you don’t
follow instructions.
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell
you what can happen if the instructions are not followed.
In the state of Massachusetts: The Commonwealth of Massachusetts plumbing code 248-CMR shall
be adhered to. A licensed plumber shall be used for this installation.
follow instructions.
Before You Start
= Do not turn the Central Water Filtration System upside down, drop, or set on sharp protrusions.
= The Central Water Filtration System has a maximum allowable inlet water pressure of 125 psi and a minimum of
30 psi. If daytime pressure is over 80 psi, nighttime pressure may exceed the maximum. Use a pressure reducing valve if necessary (Adding a pressure reducing valve may reduce the flow.). If your home is equipped with a
back flow preventer, an expansion tank must be installed in accordance with local codes and laws.
= The Central Water Filtration System works on 24V DC electrical power, supplied by a direct plug-in power supply
(included). Be sure to use the included power supply and plug it into a nominal 120V, 60 Hz household outlet
that is in a dry location only, grounded and properly protected by an overcurrent device such as a circuit breaker
or fuse.
= Do not use the Central Water Filtration System with water that is microbiologically unsafe or of unknown quality
without adequate disinfection before or after the system.
European Directive 2002/96/EC requires all electrical and electronic equipment to be disposed of accord-
ing to Waste Electrical and Electronic Equipment (WEEE) requirements. This directive or similar laws
are in place nationally and can vary from region to region. Please refer to your state and local laws for
proper disposal of this equipment.

Inspect Shipment
The parts required to assemble and install the Central
Water Filtration System are included with the unit.
Thoroughly check the Central Water Filtration System
for possible shipping damage and parts loss. Also
inspect and note any damage to the shipping carton.

How a Central Water Filtration System Works
NORMAL OPERATION
During normal operation water enters the Central
Water Filtration System and flows through several filtration processes where tastes, odors and sediment
are reduced.
CLEAN RINSE CYCLE
A Clean Rinse cycle will automatically be initiated
based on how the controller has been programmed.
The Clean Rinse cycle lifts and expands the media
bed to rejuvenate the media and then repacks the bed
for continued use. During the Clean Rinse cycle, dirt,
sediment, etc. are flushed from the Central Water
Filtration System down the drain.
APPLICATIONS FOR A CENTRAL WATER
FILTRATION SYSTEM
= Do not use the Central Water Filtration System with
water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after
the system.
= The Central Water Filtration System may not be an
effective treatment method for water sources with a
hydrogen sulfide problem (rotten egg odor or taste)
If your water has hydrogen sulfide, contact a water
treatment expert or call 1-800-972-0135.
= The Central Water Filtration System will not remove
iron and is not intended to replace iron treatment
equipment.
= Although the Central Water Filtration System has
sediment filter capabilities, additional sediment filtration may be needed in problem water applications.
5
Installation Requirements
LOCATION REQUIREMENTS
Consider the following when selecting an installation
location for the Central Water Filtration System.
= Do not operate the Central Water Filtration System
where freezing temperatures occur. Do not attempt
to treat water over 100ºF (38ºC). Freezing temperatures or hot water damage voids the warranty.
= To condition all water in the home, install the
Central Water Filtration System close to the water
supply inlet, and before all other plumbing connections, except outside water pipes.
= For a home with municipal water supply, install the
Central Water Filtration System between the home’s
incoming water supply and the water softener, if one
is being used (See Figure 3A). If the home has well
water, reverse the order of the Central Water Filtra tion System and the water softener (See Figure 3B).
= A nearby drain is needed to carry away Clean
Rinse discharge water. Use a floor drain, laundry

tub, sump, standpipe, or other options (check your
local codes). See "Air Gap Requirements" and
Valve Drain Requirements" sections. If a drain is
"
not available, it is still possible to operate the
Central Water Filtration System in a manual Clean
Rinse mode. See “Operating in Manual Clean
Rinse Mode.” The automatic Clean Rinse must be
disabled if the Central Water Filtration System will
not be connected to a drain (See Page 7).
= The Central Water Filtration System works on 24V
DC electrical power, supplied by a direct plug-in
power supply (included). Provide a 120V, 60 Hz
electrical outlet in accordance with NEC and local
codes.
= Do not install the Central Water Filtration System on
a hot water line (See Figures 3A & 3B, below).
= Avoid installing in direct sunlight. Excessive sun
heat may cause distortion or other damage to nonmetallic parts.

Installation Requirements
PLUMBING CODES
All plumbing must be completed in accordance with
national, state and local plumbing codes.
n the state of Massachusetts: The Commonwealth
I
of Massachusetts plumbing code 248-CMR shall
be adhered to. A licensed plumber shall be used
for this installation.
AIR GAP REQUIREMENTS
A drain is needed for Clean Rinse discharge water. A
floor drain, close to the Central Water Filtration
System, is preferred. A laundry tub, standpipe, etc.
are other drain options. Secure valve drain hose in
place. Leave an air gap of 1-1/2” between the end of
the hose and the drain. This gap is needed to prevent
backflow of sewer water into the Central Water
Filtration System . Do not put the end of the drain
hose into the drain.
CONNECTING VALVE TO DRAIN
VALVE DRAIN REQUIREMENTS
Using the flexible drain hose (included), measure and
cut to the length needed. Flexible drain hose is not
allowed in all localities (check your plumbing codes). If
local codes do not allow use of a flexible drain hose, a
rigid valve drain run must be used. Purchase a compression fitting (1/4 NPT x 1/2 in. minimum tube) and
1/2" tubing from your local hardware store. Plumb a
rigid drain as needed (see Figure 4, below).
NOTE: Avoid drain hose runs longer than 30 feet.
Make the valve drain line as short and direct
as possible.
It is recommended that the Central Water Filtration
System be installed near a drain. However, if a drain
is not available, it is still possible to operate the
Central Water Filtration System in a manual Clean
Rinse mode. See “Operating in Manual Clean Rinse
Mode” section. The automatic Clean Rinse function
must be disabled if the Central Water Filtration System
will not be connected to a drain.

Electrical Shock Hazard
Prior to installation on metallic plumbing,
securely install two grounding clamps and a
#4 copper wire per installation instructions.
Failure to follow these instructions can result
in death or electrical shock.
3 VALVE BYPASS
INLET - OUTLET PLUMBING OPTIONS
Always install either a single bypass valve (provided),
as shown in Figure 7, or, if desired, parts for a 3 valve
bypass system (not included) can be purchased and
assembled, as shown in Figure 6. Bypass valves
allow you to turn off water to the Central Water
Filtration System for maintenance if needed, but still
have water in house pipes.
Use either:
= Copper pipe
= Threaded pipe
= PEX (Crosslinked Polyethylene) pipe
= CPVC plastic pipe
= Other pipe approved for use with potable water
IMPORTANT: Do not solder with plumbing attached to
the single bypass valve. Soldering heat
will damage the plastic valve.
