Installation (Examples
only)
Note: In
those areas
where these
types of
installations are
approved, it
is subject
to the
approval of
the local
or state
code inspection
authority.
Applications
Series

" 7
or LF7
is especially
recommended for
shampoo sink
or similar
appli-
cations requiring
3
⁄
8
" female
connection for
convenient attachment.
It is
also suited
for other
continuous or
intermittent pressure
type installations
where water
distribution piping
flows to
potentially contaminated
containers,
equipment or
sinks. In
the event
of negative
supply pressures,
such contaminated
fluids must
not be
allowed to
backflow to
the potable
water supply
source by
backsiphonage or
other cause.
Installation
Before installing,
flush out
pipe lines
to remove
scale and
other foreign
matter. The
valve can
be installed
horizontally or
vertically. Install
the valve
in the
line with
the
arrow on
valve body
pointing in
the direction
of flow.
Teflon
®
tape
is recommended
for the
pipe threads.
To maintain
the valve
discs in
a clean
operating condition,
we
strongly recommend
a pipe
line strainer
(Watts model
27) be
installed in
the supply
line before
