will feed the water system.
4. Anchor the OneFlow
®
mounting material spanning wall studs. System must be
vertical and upright.
5. Run a suitable line from 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

6. Select the appropriate size tubing for the equipment being
fed and connect it to the outlet of the OneFlow
NOTICE
DO NOT connect the tubing to the equipment at this time.
Prior to making connection to the equipment, this line will
be used to facilitate flushing the system. As an option, a
drain valve in a tee on the outlet side of the OneFlow
tem could be provided in the line to facilitate flushing when
changing filters.
7. With OneFlow inlet valve closed, slowly open the

tem, 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 2 minutes at the
specified system flow rate to allow air bubbles to escape.
