Feed Water Chemistry Requirements; Installation Precautions - Watts OneFlow OF210-1 Manuel D'installation, De Fonctionnement Et D'entretien

Feed Water Chemistry Requirements

pH 6.5-8.5
Hardness (maximum) 75 grains (1282 ppm CaCO3)
Water Pressure 15psi to 100psi (1.03 bar to 6.9 bar)
Temperature 40°F to 110°F (5°C to 43°C)
Free Chlorine < 2 ppm
Iron (maximum) 0.3 ppm
Manganese (maximum) 0.05 ppm
Copper 1.3 ppm*
Oil & H2S Must be Removed Prior to OneFlow
Polyphosphates Must be Removed Prior to OneFlow
Silca (maximum) 20 ppm**
WARNING
!
*High levels of Copper will foul OneFlow media and typically
originates from new Copper plumbing. Wait a minimum of
4 weeks before placing system in operation. Avoid apply-
ing 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.
WARNING
!
• Connect system to cold water supply only. Water temperature
cannot exceed 110°F/43°C.
• System must be installed in a vertical, upright and level position.
• OneFlow systems must not be used in conjunction with
®
polyphosphate or any other scale inhibitor.
• Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after
the system.
WARNING
!

Installation Precautions

• Do NOT install system on line pressure above 100psi.
• Do NOT install system on HOT water line. Failure to limit line
temperature to 110°F/43°C may result in housing failure and
damage.
• Do NOT install the system backwards with the feed water
line connected to the outlet.
• Do NOT use liquid pipe compounds for fitting connections.
USE two to three wraps of Teflon® tape.
• Do NOT solder plumbing connections attached to filter
housing or inlet valve. Inlet valve and filter housing will be
damaged by high temperature.
• Do NOT allow system to freeze. Turn off water supply to
housing and drain housing if temperature falls below 32°F.
• Do NOT install system in direct sunlight or where system is
exposed to harsh chemicals or may be subjected to being
struck by moving equipment, carts, mops or any other
item that may cause damage.
• ALLOW a minimum of 3" under the housing to allow for
filter replacement.
• IF water hammer is evident, install water hammer arrestors
before the OneFlow
®
• Do NOT overtighten fitting connections into inlet valve or
housing outlet.
• Always back-up valves and fittings with a wrench when
installing a fitting to avoid turning the valve.
• Do NOT install the unit behind equipment where it may be dif-
ficult to access the system for filter replacement.
Position the OneFlow

mount the OneFlow system near any source of heat. Also,
®
do not mount the system above any device or area that would
be adversely affected by water.
