NOTICE: This system is intended for use on potable water supplies or disinfected water
containing cysts. Do not use where water is microbiologically unsafe or with water of
unknown quality. If bacterial contamination is present, a recognized method of water
disinfection is required.
Check with your public works department for applicable local plumbing and sanitation codes.
Follow your local codes if they differ from the standards used in this manual.
Operational, maintenance and replacement requirements are essential for this product to perform properly. The Culligan Water Tower
contains replaceable particulate and activated carbon
™
filters. It also includes a replaceable reverse osmosis membrane filter which is critical for the
effective reduction of Total Dissolved Solids. The filtered water should be tested periodically to
verify that the system is performing properly.

Introduction
Thank you for choosing a Culligan Water Tower
drinking water system. Your new system is
™
designed to bring you years of healthful, deliciously crystal-clear Culligan® water. With its special
faucet installed on your sink, it’s like getting bottled water straight from your kitchen tap.
With the Culligan Water Tower drinking water system, 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
With three separate water treatment technologies and its unique space-saving design, the
Culligan Water Tower drinking water system is the most advanced drinking water system available from Culligan today.
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 Water Tower drinking water system. In addition, we’ve incorporated activated
carbon and fine particle filtration to bring you one of the most effective systems available today.
Culligan Water Tower System Components
Refer to Figure 2, page 6
Sediment Filter
The sediment filter screens out dirt, sand, rust, and other microscopic par ticles 15 times smaller
than a grain of sand.
Activated Carbon Filter
The activated carbon filter gets rid of bad tastes and odors, including chlorine, if present in your
untreated water supply.
Reverse Osmosis Membrane Cartridge
The reverse osmosis (RO) membrane squeezes out dissolved substances, including radium, lead,
and many others. These substances may not be in your water. See Performance Data Sheet for
list of substances and removal percentages.
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 Culligan Water Tower drinking water
system extremely space efficient and simplifies filter changes.
Storage Tank
The storage tank holds Culligan® water under pressure for rapid delivery.

Polishing Filter
The Culligan Water Tower
drinking water system includes a second activated carbon filter in
™
the manifold as added assurance that your water will be crystal clear.
Culligan
Smartap® Water Quality Monitor and Faucet
®
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.
Your Cullig an Water Tower incorporates a proven performance indicator. The patented
Smartap
Water Quality Monitor uses dual probe LOGIC PULSE MEMORY
®
technology to accurately indicate membrane performance. A split-second power pulse compares
feed water Total Dissolved Solids (TDS) level with that of the product water. Then, by reversing
the polarity of the electronic pulse, the probes are cleaned and kept free of chemical plating.
Electronics from the Culligan Water Tower connected to the Smartap faucet provides feedback
on system operation.
Indications appear in a light bar integrated into the faucet body
front cover (Figure 1). Power is provided through a nine-volt
alkaline battery. To prolong battery life, indicator lights selfextinguish after a few seconds even if water is being dispensed.
- Green means quality Culligan water
- Orange tells you that a service check is necessary
- Yellow means a filter change is required

Application Guidelines
The Culligan Water Tower drinking water system is designed for use on potable water supplies
meeting the guidelines outlined in Table 1. The system should be installed on your home’s cold
water line. The flushing stream should discharge through an approved siphon break as illustrated
in Figure 2, page 6. Installation of this system must comply with state and local laws and regulations.

The reverse osmosis membrane filter used in this system may be damaged by chlorine. This system
includes activated carbon which protects this element by reducing chlorine. Inf luent chlorine should not
exceed 2 mg/L.
