Installation Precautions!
• Do NOT install system on line pressure above 125psi.

• 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 ® unit.
• 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
difficult to access the system for filter replacement.
Position the OneFlow ® unit in a suitable location. The direction of
flow through the OneFlow ® unit is always left to right; keep this in
mind when determining installation location. Do NOT 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.
