In addition, the Good Water Machine Nitrate models listed above have been tested and certified to ANSI/
NSF Standard 58 for effective reduction of Nitrate/Nitrite. Nitrate models are acceptable for treatment of
influent concentrations of no more than 27 mg/L Nitrate and 3 mg/L Nitrite in combination measured as
N and are certified for Nitrate/Nitrite reduction only for water supplies with a pressure of 40 psig (280
kPa) or greater.
This sytem shall only be used for arsenic reduction on chlorinated water supplies containing detectable
residual freee chlorine at the system inlet.
Refer to your Installation and Operating Instructions and printed limited Warranties for more specific
product information. To avoid contamination from improper handling and installation, your system
should only be installed and serviced by your Culligan Man. Performance will vary based on local water
conditions. The substances reduced by this system are not necessarily in your water.
Culligan water softeners are designed to work with any salt of good quality, although it is recommended
that you ask your local independent Culligan dealer. Performance will vary depending on local water
conditions. The substances reduced by this system are not necessarily in your water.
APPLICATION GUIDELINES
The Good Water Machine 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 1. Installation of this system must
comply with state and local laws and regulations.

1 Nitrate units are not certified for nitrate reduction in water supplies with a pressure less than 40 psi (280 kPa).
A booster pump is strongly recommended.
2 See the Technical Manual for all applications where TDS exceeds 1000 ppm (1000 mg/L). A booster pump is
strongly recommended.
3 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. Influent chlorine should not exceed 3 mg/L.
4 A softener is strongly recommended for water over 10 gpg.
