‐‐
a
visual
means
to
verify
that
detergents
and
sanitizers
are
delivered;
or
a
visual
or
audible
alarm
to
signal
if
detergents
and
sanitizers
are
not
being
delivered
to
the
respective
washing
and

For
ADS
family
models
of
ET
‐
AF
and
the
model
ASQ,
the
chemical
Flow
Indicator
(084
‐
6403)
is
the
visual
means
to
indicate
liquid
is
flowing
in
the
feeder
system
for
detergent
and
sanitizer.
In
each
of
the
tubes
machined
through
the
clear
plastic
housing,
there
is
a
black
colored
marble
(099
‐
1008).
Squeeze
tube
material
(092
‐
2000)
is
inserted
in
both
upper
and
lower
tube
openings.
These
tubes
are
pushed
into
the
holes
of
the
housing
and
held
in
place
by
tension
of
the
tube
wall
against
the
housing’s
inner
surface.
When
inserting
the
squeeze
tubes
into
the
housing,
lubrication
using
dish
soap
is
helpful.
When
the
top
tube
of
the
indicator
is
connected
to
the
inlet
side
of
the
chemical
peristaltic
pump,
liquid
is
drawn
up
through
the
supply
tube
of
the
chemical
bucket.
The
liquid
is
drawn
into
the
bottom
of
the
Flow
Indicator
housing
and
lifts
the
black
indicator
marble
upward
in
the
visual
chamber.
This
movement
shows
flow
of
the
liquid
in
the
tube.
The
tube
with
red
colored
liquid
will
indicate
detergent
flowing,
the
tube
with
clear
liquid
will
indicate
sanitizer
(chlorine)
flowing.
The
operator
should
be
informed
that
this
movement
of
the
marbles
in
the
housing
is
the
visual
indication
that
chemicals
are
being
delivered
for
the
washing
and
sanitizing
operations
of
the
dishmachine.
Management
should
be
notified
if
there
is
no
movement
of
the
indicators.
