WATER
INSTALLATION
Water
installation
is
carried
out
as
shown
in
figures
3
and
4.
The
hot
water
line
to
the
dishwasher
must
pro
vide
20
psi
of
water
pressure.
The
hot
water
heater
should
be
set
to
deliver
140
F
(not
lower
than
120°F)
water
temperature
to
the
dishwasher
for
best
results.
Use
¾”
copper
tubing
inlet
line.
CAUTION:
Do
not
confuse
static
pressure
with
flow
pressure.
Static
pressure
is
the
line
pressure
in
a
“no
flow”
condition
(all
valves
and
services
are
closed).
Flow
pressure
is
the
pressure
in
the
fill
line
when
the
solenoid
valve
is
opened
during
the
cycle
THE
DISPLAY
OF
THE
PRESSURE
GAUGE
SHALL
BE
CLEARLY
VISIBLE
OF
THE
OPERATOR
OF
THE
MACHINE.
THE
GAUGE
SHALL
HAVE
INCREMENTS
OF
1
psi
(7
kpa)
OR
SMALLER
AND
SHALL
BE
ACCURATE
TO
±2
psi
(±14
kpa)
IN
THE
20
psi
(103
‐
172
kpa)
RANGES.
IF
THE
GAUGE
IS
LOCATED
UPSTREAM
OF
THE
CONTROL
VALVE,
IT
SHALL
BE
MOUNTED
IN
AN
ACCESSIBLE
VALVE
WITH
A
¼
IN
IRON
PIPE
SIZE
CONNECTION.
If
the
water
pressure
is
less
than
20
psi
(1.4
kg/cm
2
),
installation
of
a
water
pump
is
required
as
shown
in
Fig.
4.
In
areas
where
the
pressure
fluctuates
or
is
greater
than
the
recommended
pressure,
it
is
suggested
that
a
water
pressure
regulator
be
installed.
