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 re-
quired for installation. Please review operating pressures, temperatures
and water chemistry limitations to ensure compatibility.

Feed Water Chemistry Requirements
pH 6.5 to 8.5
Hardness (maximum) 75 grains (1282 ppm CaCO3)
Water Pressure 15psi to 100psi (103 kPa to 6.9 bar)
Temperature 40°F to 110°F (5°C to 43°C)

Manganese (maximum)* 0.05 mg/l
Copper (maximum)* 1.3 ppm
Oil & H2S Must be removed prior to OneFlow
Polyphosphate Must be removed prior to OneFlow
Silica (maximum)
20 ppm
WARNING
!
High levels of Copper will foul OneFlow
=
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 limita-
tion 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
®
formation inside the plumbing system at influent hardness levels of 75
grains per gallon of calcium carbonate and less. Due to variances 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.

Intermittent duty is defined as less than 2 hours of Maximum

combining systems in an array.

*** Exceeding maximum flow can reduce effectiveness and void warranty.
Pressure drop at peak flow rate is less than 10 psi.
Pressure drop reading taken with inlet and outlet gauges installed at a com-
mon elevation and 80 degree feed water.
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. Special attention needs to
be taken to properly plumb system. On top of the head, "Inlet"
and "Outlet" are embossed above the each port.
