Equipment Specifications - Watts OneFlow OF1465-50TM Manuel D'installation, D'utilisation Et D'entretien

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.
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 100°F (5°C to 38°C)
Chlorine < 2ppm
Iron (maximum) 0.3 mg/l*
Manganese (maximum) 0.05 mg/l**
Copper (maximum) 1.3 ppm**
Oil & H2S Must be removed prior to OneFlow
Silica (maximum) 20 ppm***
NOTICE
*Iron and Manganese
Just as with conventional water softening media, OneFlow
media needs to be protected from excess levels of certain met-
als that can easily coat the active surface, reducing its effective-
ness over time. Public water supplies rarely, if ever, present a
problem, but if the water supply is from a private well, confirm
that the levels of iron (Fe) and manganese (Mn) are less than
0.3 mg/L and 0.05 mg/L, respectively.
NOTICE
**Copper
Pursuant to the EPA drinking water standards, the maximum
copper concentration permitted is up to 1.3 ppm. Copper
usually originates from new copper plumbing upstream of the
OneFlow® system and high levels of copper can foul OneFlow
media. To further minimize any problem with excess copper,
avoid applying excess flux on the inner surfaces of the pipe
and to use a low-corrosivity water soluble flux listed under the
ASTMB813 standard. For applications with copper concentra-
tion greater than 1.3 ppm, please contact Watts Pure Water
Technical Service at 1-800-224-1299.
NOTICE
***Silica
OneFlow media does not reduce silica scaling. While silica
®
tends to have a less significant effect on scale formation than
other minerals, it 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.
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
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.

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.
*** Exceeding maximum flow can reduce effectiveness and void warranty.
Pressure drop at peak flow rate is less than 10 psi.
