Plumbing
Recommendations
1. Always
install
strainers
(even
if
not
supplied
with
unit)
immediately
before
Steamix
203
and
down-stream
of
all
other
components
including
Check
Valves.
Install
strainers
with
the
arrows
pointing
towards
the mixing
valve
when
placed
in
horizontal
or
vertical
supplies
so
that
the
strainer
screen
traps
debris.
2. If
widely
fluctuating
steam
pressure
is
a
common
occurrence,
a
pressure
regulator
set
to
the
lowest
pressure
encountered
should
be
installed
a
minimum
of
six
feet
upstream
from
the
mixing
valve.
3. It
is
recommended
a
steam
trap
be
installed
on
the
steam
supply
piping
upstream
of
Steamix
203
to evacuate
or
return
the
condensate.
Trap
should
be
installed
at
least
6
feet
away
but
no
greater
than
15
feet
away
from
the
inlet
of
Steamix
203
where
possible.
4. Inlet
check
valves.
5.

Start-Up
Procedures
Prior
to
operating
the
valve,
the
outlet
temperature
must
first
be
set
within
the
required
operating
parameters
as
specified
by
plant
management.
The
available
temperature
range
of
the
mixing
valve
is
from
ambient
inlet
water
temperature
to
almost
boiling.
To
set
the
mixing
valve
to
the
required
temperature:
1. Turn
the
temperature
regulating
lever
clockwise
as
far
as
it
will
go
to
close
the
steam
inlet.
(This
may
take
several
revolutions.)
2. Remove
the
water
flow
regulator
locking
cap
using
a
3/32"
Hex
Key
to
loosen
the
set
screw
located
at
the
base
of
the
cap.
Fully
open
the
cold
water
regulator
by
turning
it
counter-clockwise.
The
mixing
valve
is
now
in
the
full
cold
position.
3. Open
the
inlet
flow
control
valve(s)
and
spray
nozzle
(if
installed)
so
that
maximum
flow
is
achieved.
4. Turn
the
temperature
regulating
lever
counter-clockwise
until
the
desired
temperature
is
obtained.
5. If
the
desired
temperature
is
not
reached
when
the
temperature
control
lever
is
fully
open,
turn
the
water
flow
regulator
clockwise
until
the
required
temperature
is
achieved.
6. Replace
the
water
flow
regulator
locking
cap.
7. The
mixing
valve
is
now
set
so
that
it
can
be
adjusted
from
its
maximum
temperature
to
cold
by
moving
only
the
temperature
regulating
lever.
