Installation
Tighten the Tank Head
Check the head on top of the tank. It is common for it to loosen
during shipment. Tighten the head by hand until tighten.
NOTICE
Anytime OneFlow
®
systems are installed above the ground floor
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 (not included). The vacuum relief
valve should be installed on the outlet of the system.
NOTICE
Install Piping
Connect the inlet and outlet plumbing according to your
preferences and any applicable local codes. Include sample/
drain ports with hose-bibb connections on the inlet and outlet
piping to facilitate startup and service.
• We recommend the installation of a dual-union ball-valve on
the inlet and outlet to isolate and outlet to isolate the tank for
servicing or install option bypass valve that is sold separately.
• A full bypass should be installed so that the full service flow
can be routed around the system as needed for servicing.
