Installation Precautions

•DoNOT install system on line pressure above 125psi.

•DoNOT install thesystem backwards with the feed water line connected to the outlet.

•DoNOT use liquid pipe compoundsfor fitting connections. USE a maximumof twoto three wraps of teflon tape.

•DoNOT solder plumbing connectionsattached to filter housing or inlet valve. Inletvalve and filter housing will be damaged by high temperature.

•DoNOT allow system to freeze. Turn offwater supply to housing and drain housing if temperaturefalls below 32°F.

•DoNOT 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

anyother item that may causedamage.

•IFwater hammer is evident, install water hammer arrestors before OneFlow unit.

•DoNOT overtightenfitting connections intoinlet valve ourhousing outlet.

•Always back-up valves and fittings with a wrench when installing a fitting to avoid turning thevalve.

•ALLOW a minimum of 3'' under the housing to allow for filter replacement.

Position the OneFlow unit in a suitable location downstream from existing filters. 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.

Installation Procedure

1. Turn off all equipment to be fed by the OneFlow System, locate water supply
cut-off valve and turn off.

2. Determine if water line has an existing water treatment system. If so, examine
system for use of polyphosphate or other scale inhibitors. OneFlow will not be
effective if used in conjunction with other scale inhibitors. Remove the scale
inhibitors from the water line or discontinue installation.

3. Install a 1/2'' and 3/4'' full-flow ball valve on the water supply side that will feed
the water system.

4. Anchor the OneFlow System on a wall stud or suitable mounting material
spanning wall studs. System must be upright and vertical.

5. Run a suitable line from the 1/2'' full-flow ball valve at the tap water source to the
inlet ball valve on the left side of the OneFlow system. Use 2-3 wraps of teflon
tape and brace the inlet ball valve on the system with a wrench when connecting
the feed water line. NOTE: DO NOT OVERTIGHTEN CONNECTION FITTING INTO
BALL VALVE.

6. Select the appropriate size tubing for the equipment being fed and connect it to
the outlet of the OneFlow System. NOTE: DO NOT connect the tubing to the
equipment at this time. Prior to making connection to the equipment this line will

the outlet side of the OneFlow system could be provided in the line to
facilitate flushing when changing filters.

7. With System inlet valve closed, slowly open the 1/2'' full-flow ball valve at
the tap water source. Check for leaks.

8. If a drain valve was not installed on the outlet side of the system, hold the
tubing that will connect to equipment in a clean bucket or over sink or
drain. Open the system inlet feed valve and allow water to flush through
system for 10 minutes at the specified system flow rate to allow air and
any carbon fines to escape. NOTE: NO ACTIVATION IS REQUIRED FOR
THE ONEFLOW SYSTEM TO PERFORM PROPERLY. FLUSHING IS
RECOMMENDED TO ALLOW AIR TO ESCAPE THE SYSTEM AND
REMOVE ANY CARBON FINES PRIOR TO CONNECTING TO EQUIPMENT.

9. Make certain that the end of the tubing to be connected to the equipment
is clean and sanitized.

10. Connect tubing to equipment. Open all water supply valves and check
for leaks.

11. If no leaks turn on equipment and check for normal operation.

12. Register your warranty using the enclosed warranty card.
