Indoors Installation
Ames Model 3000B may be installed in either a vertical or
horizontal position. Pipe lines should be thoroughly flushed to
remove foreign material before installing the unit. A strainer
should be installed as shown, ahead of backflow preventer to
prevent disc from unnecessary fouling. Install valve in the line
with arrow on valve body pointing in the direction of flow.
For indoor installations, it is important that the valve be easily
accessible to facilitate testing and servicing. Do not install in a
concealed location.
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.
It is important that Model 3000B be tested periodically in
compliance with local codes, but at least once a year or more
often depending upon system conditions.
Note Fire Protection System Installations: The National Fire
Protection Agency (NFPA) Guidelines require a confirming flow test
to be conducted whenever a “main line” valve such as the shutoff
valves or a backflow assembly have been operated. Certified testers
of backflow assemblies must conduct this test. The trim valves of
the detector meter bypass line, on assemblies so equipped, should
be shut off during the confirming flow test. When the test is
completed the trim valves must be retuned to a fully open position.
Basic Installation Instructions
Outside Installation — Above Ground
In areas where freezing conditions do not occur, Model 3000B
can be installed outside of a building. The most satisfactory
installation is above ground and should be installed in this
manner whenever possible.
In an area where freezing conditions can occur, Model 3000B
should be installed above ground in an insulated enclosure.
Annual inspection of all water system safety and control valves is
required and necessary. Redular inspection, testing and cleaning
assures maximum life and proper product function.
