Ames Model 2000 CIV and 3000 CIV backflow
preventers may be installed in either a vertical or
horizontal position.
Install valve in the line with arrow on valve body
pointing in the direction of flow.
They should always be installed in an
accessible location to facilitate testing
and servicing.
Pipe lines should be thoroughly flushed to re-
move foreign material before installing the unit. A
strainer should be installed as shown, ahead of
backflow preventers to prevent discs from unnec-
essary fouling.
CAUTION: Do not install with strainer when backflow
preventer is used on seldom-used water lines which
are called upon during emergencies, such as fire
sprinkler lines, etc.
For technical assistance, contact your local Ames
representative.
It's 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.
