What the Drinking Water Purifier Will Do 

The 4000 Nanotechnology Certified Under Counter Filtration System is a water purification treatment system.  This system uses a triple 
filter design to reduce unwanted elements in your drinking water.  Possible elements may include chlorine, lead, virus, bacteria, cysts, 
particulates and numerous organic compounds.   

The 4000 Nanotechnology Certified Under Counter Filtration System utilizes the patented Nano and other technologies in a systematic 
approach to ensure the water supply conforms to EPA Guide Standard for the removal of 99.9999% Bacteria, 99.99% Viruses, and 99.95% 
Cysts.   The 4000 Nanotechnology Certified Under Counter Filtration System is designed to discontinue water flow when its capability to 
filter unwanted elements has been exhausted.  This will help safeguard the consumer against contaminated water.  Replace all filters every 
12 months or 1000 gallons. 

NOTE:  A performance data sheet is included and lists what elements will be reduced from the water supply.  (Please note that not all 
elements may be present.)  This data sheet lists the individual contaminants and microbial reduction performance. 

The drinking water purifier system is designed to fit under the kitchen or bathroom sink or any other area that is suitable.  A COLD water 
supply pipe is required within a few feet.  If water supply pipe is farther than what the tube will reach, you can purchase longer lengths of 
tubing from your local home improvement center. 

 

NOTE:  Make sure the tubing is acceptable for use on potable water supplies. 

Before You Start 

v

 

In order to receive all of the benefits of your microbiological drinking water purifier, be sure to read all steps in this guide 
carefully and follow steps exactly. 

 

v

 

This system is intended for use with municipal and/or well-supplied water only.  It is not intended for use with surface water such 
as from a lake or runoff. 

v

 

Do not use for the treatment of water that is visually contaminated (cloudy) or has an obvious contamination source, such as 
contamination by raw sewage. 

v

 

Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts. 

v

 

System is not intended to convert wastewater or raw sewage into drinking water.

 

v

 

Installation and plumbing should comply with all local laws and regulations.  Consult with your licensed plumber.   

NOTE:

 In Massachusetts, plumbing code 248 CMR 3.00 and 10.00 shall be adhered to.   

v

 

The microbiological drinking water purifier works on water pressure of 30 psig (minimum) to 100 psig (maximum).  If your house 
water pressure is over the maximum, install a pressure reducing valve in the water supply pipe to the filter system. 

v

 

Do not install the microbiological drinking water purifier outside, or in extreme hot or cold temperatures.  Temperature of the 
water supply to the under-sink drinking water filter system must be between 40

F and 100

F.  Do not install on hot water. 

v

 

Do not use with water that is microbiologically unsafe or of unknown quality without disinfection before or after the system. 

v

 

Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts. 

Precautions 

 

This system is for “cold water” use only. 

 

Protect filters against freezing, which can cause cracking of the filter and water leakage. 

 

The rubber O-ring provides the water-tight seal between the cap and the bottom of the housing.  It is important that the      
O-ring be properly seated in the groove below the threads of the housing or a water leak could occur. 

 

To prevent costly repairs or possible water damage, the sump of plastic housings must be replaced every ten years.  If sump is 
older than recommended, replace immediately.  Date sump for reference and indicate replacement date.
