Thank You
Welcome To Your New World of Better Living with Culligan Water.
Thank you for choosing a Culligan Aquasential™ Tankless Reverse Osmosis (RO) drinking water
system. Your new system is designed to bring you years of deliciously crystal-clear Culligan
water. The best part is it comes right from the tap. No more lugging around bottles or waiting for
pitchers to slowly fill up. With your continuous supply of great tasting water, not only can you get
your 8 glasses a day but you can easily use it for cooking, coffee, juice, baby formula, ice cubes,
anything you use water with.
The important thing to remember is to change out your filters on a regular basis. The quality of your
water is only as good as the quality of your filters. The CF and CB filters are designed to last for 4,755
gallons (roughly 12 months). RO membranes will last longer if used with pre-filtration. Filter cartridge
life indicators are located on both the system faucet and main unit so that you will be alerted to change
your filters and membrane at the proper intervals.
Purpose of Each Level of Filtration
Pre-filtration for this system is used to reduce large substances from the water before they
reach the reverse osmosis membrane. The use of our CF pre-filtration cartridge helps extend
the membrane’s life. The CF filter combines both a sediment and bad taste and odor reduction
filter in one. Sediment is defined as sand, dirt, silt, fine sand and or coarse sand that can be
found in many water supplies. Carbon is used to reduce chlorine taste and odor. Most people
often describe this taste as being slightly chemical or they equate their drinking water to that of
the local pool. Municipalities use chlorine to disinfect the water on the way to your home. This
is a necessary step in order to deliver safe water to your home, but depending on the level of
chlorine, by the time it reaches your home the taste of your water may be unpalatable.
The Aquasential™Tankless RO system utilizes a high capacity reverse osmosis membrane,
which uses a tightly woven membrane that acts as a barrier to substances. Water is pushed up
against this membrane at pressure. Depending on the weave of the membrane only a certain
percentage of substances can pass through. This system’s high capacity membrane can reduce
up to 95% of substances.
The Aquasential™ Tankless RO has been tested and certified by
WQA against NSF/ANSI 372, CSA B483.1 and NSF/NSF 58 for
the reduction of TDS as verified and substantiated by test data.
For installations in Massachusetts, the Massachusetts Plumbing
Code 248 CMR shall be adhered to. Consult your licensed plumber
for installation of this system. This system and its installation must
comply with state and local regulations. The use of saddle valves
is not permitted.
Congratulations on selecting one of Culligan’s Aquasential™
Tankless ROs. With Culligan’s many years of knowledge and
experience in water treatment, you can be confident that the
model you selected has been designed and engineered to
provide years of service with a minimum of care and attention.
