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.
