Equipment Specifications

OneFlow systems are complete, self-contained, loaded with
®
media, and ready to use. A simple inlet and outlet connection is all
that is required for installation. Please review operating pressures,
temperatures and water chemistry limitations to ensure compatibility.

WARNING
!
High levels of Copper will foul OneFlow media and typically origi-
nates from new Copper plumbing. Wait a minimum of 4 weeks
before placing system in operation. Avoid applying excess flux
on the inner surfaces of the pipe and to use a low-corrosivity
water soluble flux listed under the ASTM B813 standard.
NOTICE
OneFlow media does not reduce silica scaling. Silica can act as
a binder that makes water spots and scale residue outside the
plumbing system difficult to remove. This 20 ppm limitation is for
aesthetic purposes.
NOTICE
Water known to have heavy loads of dirt and debris may require
pre-filtration prior to OneFlow.
* See note about iron, manganese and copper on page 2.
Systems using OneFlow technology prevent hard water scale for-
mation inside the plumbing system at influent hardness levels of
75 grains per gallon of calcium carbonate and less. Due to vari-
ances in water chemistry, certain aesthetic conditions external of
the plumbing system may not be attained.
OneFlow is designed for the treatment of potable water that
meets the requirements of the current USEPA Safe Drinking
Water Act.

* The overall height and the height of the inlet fitting varies due
to material variations and assembly tolerances. Please allow
additional clearance above the tank for making connections.

Water Temperature
Continuous Duty Systems:
System 40°F 45°F
OF1465-50 40 44
OF1665-75 45 51
Intermittent Duty Systems:
OF1465-50
OF1665-75
* Intermittent duty is defined as less than 2 hours of Maximum
Flow per 24 hour period. Higher Flow rates can be achieved
by combining systems in an array.
NOTICE
• We recommend the installation of a dual-union ball-valve on
the inlet and outlet to isolate the tank for servicing.
• A full bypass should be installed so that the full service flow
can be routed around the system as needed for servicing.
• The OneFlow system operates in the Up-Flow mode which
®
is opposite of a conventional softener. The inlet is on the bot-
tom, the outlet on the top.
