Before You Begin
Please read this manual before proceeding with the professional installation and use of
your system. Installation, operation, and maintenance requirements are essential to the
performance of your system – failure to follow any instructions or operating parameters
contained herein may lead to product damage or product failure.

• Replacement lters can be purchased directly from Multipure. For the latest prices, please
visit our website at http://www.multipure.com/store/.
• The Multipure Aquasource Whole House System uses a set of 3 identical replacement
lters (Model Nos. CB20 or CB20LSI). Actual lter life depends on the amount of water
used and the level of particulate matter in the water being processed. See 2.1: Regarding
Filter Capacity for additional details.
• If your water has a noticeable amount of large particulate matter (e.g., sand, dirt, leaves,
etc.), Multipure recommends the installation of a Sediment Filter (purchased separately)
before the Multipure Aquasource, which extends the useful life of the replacement lter
cartridges.
• The Multipure Aquasource Whole House System is designed to be most effective with
municipally-treated water.
• The Multipure Aquasource Whole House System is designed for cold water use only, and
at a maximum water pressure of 100 psi.
• The Multipure Aquasource housing operates in an upright position. Please leave at least
22” clearance above the housing for lter cartridge changes.
• Do not allow water to freeze in the system. If the system is exposed to freezing temperatures,
drain water from the system and remove the lter cartridges. Allow the lters to thaw
before replacing and reusing.
• Do not allow water to sit in the system for extended periods of time (i.e., 10 days or more)
without use.
• It is always advisable to ush all of the water pipes in your home whenever water has
been standing in the pipes for an extended period of time.
• Check for compliance with any state or local laws and regulations before use.
Important Notice
• The installation of a Whole House Water Treatment System will cause a reduction in the
water ow rate or pressure. Flow rate/pressure drop will vary depending on a variety of
factors, including but not limited to the size of the pipes in your home, the number of
ttings and outlets, and the height to which the water must be delivered.
• You may encounter a noticeable water pressure drop if multiple water outlets (e.g.,
toilets, showers, dishwashers, etc.) are open at the same time.
