Hot Water System Overview

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, tempera-
tures and water chemistry limitations to ensure compatiblity.

Polyphoshates
Silca (maximum)
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
The tank is only partially filled with media. The
tank is much lighter than a water softener and may appear to
be nearly empty. This is normal and necessary for the Upflow-
fluidized bed operation of the system.

CAUTION
!
• Do not let the system freeze. Damage to the tank may result.
• System must be operated in a vertical position. Do not lay
it down during operation. The system may be placed in any
position for shipping and installation but must be operated in
the vertical position.
• Must be used on hot water. This system is not designed for
cold (<100°F) water. For cold water operation contact your
dealer for a system designed for cold water operation.
