Indoors -

Figure 1

Check local codes for installation requirements. 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

inline with arrow on valve body pointing in the direction of flow.
For indoor installations, it is important that the valve be easily acces-

sible 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 emergen-

cies, such as fire sprinkler lines, etc.
It is important that Series 007 and LF007 be tested periodically in

compliance with local codes, but at least once a year or more often

depending upon system conditions. Regular inspection, testing and

cleaning assures maximum life and proper product function.

NOTICE

Fire Protection System Installations

such as the shutoff valves or a backflow assembly have been oper-

ated. Certified testers of backflow assemblies must conduct this

test. The trim valves of the confirming flow test. When the test is

completed, the trim valves must be returned to a fully open position.
