IMPORTANT: Inquire with governing authorities for local instal-
lation requirements.
NOTE: For Australia and New Zealand, line strainers should be
installed between the upstream shutoff valve and the inlet of
the backflow preventer.
Its important that this device be tested periodically in
compliance with local codes, but at least once per year
or more as service conditions warrant. If installed on a
fire sprinkler system, all mechanical checks, such as
alarm checks and backflow preventers, should be flow
tested and inspected internally in accordance with NFPA
13 and NFPA 25.
