TYPE
OF
CHEMICALS—Use
only
commercial
grade
low
‐
energy
chemicals.
For
proper
operation,
use
non
‐
foaming
detergents
and
buffered
sanitizer.
Do
not
wash
gold,
pewter,
silver,
or
silver
‐
plate
with
chlorine
based
sanitizers.
High
concentrations
of
chlorine
sanitizers
and
caustic
detergents
will
cause
damage
to
metals
and
welds.
Do
not
exceed
50
parts
‐
per
‐
million
(PPM)
“free”
or
available
chlorine.
Any
setting
higher
than
50
ppm
will
be
dependent
on
local
health
requirements,
however,
the
increased
chlorine
will
result
in
higher
corrosion
of
metal
parts.
Purpose
‐
built
ware
‐
washing
dispensers
are
needed
to
properly
meter
chemicals
for
wash
and
rinse.
These
dispensers
are
included
with
this
model.
Manually
adding
industrial
chemicals
to
the
dishmachine
is
unsafe
and
not
approved.
CHEMICAL
LINES—Place
color
coded
tubes
into
proper
chemical
containers.
The
containers
need
to
be
as
close
to
the
machine
as
possible
and
at
floor
level.
This
may
require
shortening
of
the
flexible
chemical
transfer
tubes.
On
the
side
of
the
control
box
door,
there
are
chemical
prime
switches.
There
is
a
decal
identifying
each
switch.
To
prime
chemicals,
use
these
momentary
prime
switches,
verifying
that
all
three
pumps
rotate.
If
a
chemical
pump
