Installation
Tighten the Tank Bushings
Tank bushing. Rotate
Clockwise to tighten.
Lay the tank down and check the bushings
on the inlet and outlet (bottom and top) of the
tank. It is common for them to loosen during
shipment. Tighten the bushings with a strap
wrench as needed
NOTICE
It is very important to use fl exible connections on the inlet
and outlet plumbing in the horizontal orientation as shown in the
images on this page. The tanks expand and contract with water
pressure fl uctuations. Flexible connectors will prevent plumbing
and tank leaks. The EDP code for the suggested Watts 2" Flex-
ible Connectors is C515285 (Two are required for installation).
Anytime OneFlow systems are installed above the ground fl oor
®
of a building it is recommended that a vacuum relief valve
also be installed to protect against tank collapse in the event
the plumbing system is drained. If a vacuum relief valve is not
used then the system should be placed in bypass anytime the
plumbing system is drained. The EDP code for the suggested
vacuum relief valve is 0556031. The vacuum relief valve should
be installed on the outlet of the system.
Install Piping
Connect the inlet and outlet plumbing according to your prefer-
ences and any applicable local codes. Include sample/drain
ports with hose-bibb connections on the inlet and outlet piping
to facilitate startup and service.
WARNING
!
Support the Piping
The full weight of the piping and
valves must be supported by uni-
strut, pipe hangers or other means.
The tank connections cannot sup-
port the weight of the piping. This
photo from a multi-tank system
installation shows properly sup-
ported piping.
Start-Up
Connect a hose to the hose bibb on the
outlet of the tank. Run the hose to a drain.
Slowly/partially open the supply water
ball valve. Allow the tank to slowly fi ll with
water. When a steady stream of water ap-
pears at the drain, close the supply valve.
Open the inlet and outlet valves on the
system. Transfer the bypass valves from
Bypass to the Service position. Open
a nearby faucet downstream from the
OneFlow system to relieve any air.
®
Check for leaks. Repair as needed.
Fill in install date and rebed due date on
product label located on front of each
tank as reminder to replace OneFlow
media every 3 years.
The system is now ready for service.
