SPECIFICATION GUIDELINES
The system makes a good supply of drinking water each day.
How much it will make depends primarily on these things...

softener is recommended. Failure to install a water softener will reduce
the life of the Reverse Osmosis membrane. See chart for additional
information on the possible need for a water softener.

a. If house water pressure is over 80 psi, install a pressure reducing valve in the water supply line. If house water pressure
is under 40 psi, install a Reverse Osmosis booster pump (contact your local plumbing supply company).
b. Removed (maximum of 2.0 ppm) by the Reverse Osmosis prefilter. REGULAR MAINTENANCE IS REQUIRED. Chlorine will
destroy the Reverse Osmosis membrane.
c. Theoretical tank capacity. When tested according to NSF/ANSI Standard 58 at 50 psig inlet pressure, tank capacity is
2.3 gallons.
