INTRODUCTION
Thank you for choosing a Culligan®Good Water Machine™reverse osmosis
water system. Your new system is designed to bring you years of healthful,
deliciously crystal-clear Culligan®water. Product water from this system can
be used for a variety of light commercial purposes such as ice and coffee
machines, drinking water, laboratories and many others. Be sure to check the
specifications of the accessory equipment for compatibility with this system.
With three separate filter technologies and its unique space-saving design, the
Good Water Machine is the most advanced drinking water system available
today from Culligan.
2
Particle Filter
The particle filter screens out dirt, sand, rust, and other microscopic particles
15 times smaller than a grain of sand.
Activated Carbon Filter
The activated carbon filter gets rid of bad tastes and odors, including chlo-
rine. If present in your untreated water supply.
Reverse Osmosis Membrane Filter
The reverse osmosis (RO) membrane filter squeezes out dissolved substances.
These substances may not be in your water.
Manifold Assembly
The manifold serves as the functional hub of the system, directing and
regulating the flow through each of the system's components. It makes the
Good Water Machine extremely space efficient and simplifies filter changes.
Storage Tank
The storage tank holds up to 9 gallons of triple-filtered Culligan®water under
pressure for rapid delivery. Optional two and three-gallon tanks are available.

ABOUT YOUR SYSTEM
The reverse osmosis method of water treatment has long been regarded as one
of the most efficient and effective ways to reduce impurities. It’s the technology
we’ve used to build your new Culligan Good Water Machine. In addition, we’ve
incorporated activated carbon and fine particle filtration to bring you one of the
most effective systems available today.

SYSTEM PERFORMANCE
The Culligan®Good Water Machine Model LC-50 is designed for high
reduction of Total Dissolved Solids (TDS) from potable water supplies. Typical
installations will provide TDS reduction of 90% or higher and production of
up to fifty gallons per day. Please note that system performance will vary
depending upon the specific characteristics of the water supply, such as TDS
level, pressure, and temperature. Please consult the Culligan AC Model Series
Technical Manual, part number 01881946 for more detailed performance
information.
The substances removed by this system are not necessarily in your untreated
water. See Performance Data Sheet for exact percentages of contaminant
removal.
Polishing Filter
The Good Water Machine™includes a second activated carbon filter as added
assurance that your water will be crystal clear.
Faucet (optional)
The special drinking water faucet mounts conveniently on your kitchen sink.
A simple twist of the handle is all it takes to enjoy refreshing Culligan drinking
water.

HOW TO USE YOUR SYSTEM
With the Good Water Machine™, you’ll get a continuous supply of clear,
refreshing water for drinking and cooking. But Culligan improves a lot more
than just water. Crystal clear Culligan®water is ideal for:
• coffee • recipes • pasta
• tea • baby formula • ice cubes
• soup • houseplants • steam irons
• juice • pets • drink mixes
• everything you make with water
PERFORMANCE CHECK
To check the performance of your Good Water Machine, it is necessary to
measure the total dissolved solids (TDS) level of the filtered water. This simple
test can be done quickly by your dealer.
The Good Water SentryTM Water Quality Monitor is another way to keep track
of your system’s performance. This optional accessory checks your drinking
water each time you use the special faucet, and signals when the membrane
filter may need to be replaced.
If the water quality of your system seems to have declined, drain the storage
tank and allow the system to refill. If the problem persists, call your Culligan
Man for service.
