AUTOMATIC STERILMATIC STEAM PRESSURE STERILIZER
MODEL
STM-E
ELECTRICALLY OPERATED, TYPE C
Your Sterilmatic Sterilizer has been developed
to
answer the need
for
a compact, automatic,low-
cost steam pressure sterilizer. The following
in-
structions cover installation. Should service be
required, it
is
readily available by contacting our
authorized service agency located nearest
to
you.
The name
of
your local service company can be
obtained from your Market Forge Representative
in
your area or by contacting the Hospital Division
Service Department, Market Forge, Industrial
Way,
Wilmington, Massachusetts 01887, telephone

617 -658-5196.
INSTALLATION
Set sterilizer on counter, using
4"
legs
provided with
unit
or
an optional stainless steel stand with under·
shelf and adjustable feet. If your Sterilmatic includes
a water-cooled exhaust condenser,
we
recommend
the use of the sterilmatic stand. part number 95{)300.
First
level
unit
in
place. then by adjusting front
legs
pitch
the
unit forward
1/4"
to
insure positive drain-
age
of the cylinder.
ELECTRICAL
Connect
to
proper electrical supply box and discon·
nect switch
as
shown on one of the following sche-
matic diagrams. (208 volt or 230 volt, single or three
phase). Connection
is
located behind the terminal
box cover at the lower left side of unit. Whether
the supply current
is
208 volt or
240
volt, single
phase or three phase,
all
control circuits are 120 volts.
In
order
to
accomplish this. a current-carrying
grounded neutral must be provided. Thus, a three
phase system must be 4·wires and a single phase
system must be 3-wires.
If
a current-carrying ground-
ed neutral
is
not available from the power source, a
separate 120 volt circuit must be run. Most electrical
codes require, and
we
recommend,
that
a separate dis·
connect switch be located, within sight
of
the sterili·
zero
When
a separate 120 volt control circuit must be
run, this must also
be
part of the disconnect box
assembly.
OUTSIDE VENTING
Connect 1/2 inch I.P.S. exhaust
to
outside vent con·
nection located on the
top
of
the control housing.
IMPORTANT: Exhaust line must be vented
to
the
outside
to
eliminate
the
exhausted steam and
the
accompanying noise from entering the room. 1/2
inch copper tubing may
be used alternately.
length
of
the
line should
not
exceed 15 feet and should have
a minimum
of
bends. The line should slope down-
ward after leaving the sterilizer
in
order
to
insure a
condensate drainage.
WATER-COOLED EXHAUST CONDENSER
If
outside venting
is
not possible. an optional
water-cooled condenser
is
available for connec·
tion
to
an open drain. For details
of
the instal·
lation on the
STM-E
Sterilizer, see drawing
117-0072. covering
both
electrical and plumb·
ing
connections
RECORDING THERMOMETER
If
a recording thermometer
is
provided, see in·
structions with the thermometer for installation.
TRAY SUPPORTS
Install side tray supports. Tray supports are at-
tached by means
of
key-hole clearance slots which
are slipped over studs located
on
the
sides of the
Sterilmatic chamber. Install so
that
open end
of
the channel sides faces the sides of
the
sterilizer.
BAFFLE INSTALLATION
To
insure maximum drying
of
packs, a baffle
is
supDlied with your
STM-E
Sterilmatic. Ptace per·
forated splash baffle
in
the
bottom
of
the
sterilizing
chamber. Install small baffle with no perforation
at
the rear
of
the upper tray support channel. (Install
as
shown on form H-1718.)
OPERATION CHECK
To check for proper operation
of
unit:
1. Fill chamber with 4
to
6 quarts
of
ordinary
tap water.
2. Close chamber door.
3. Set exhaust selector
to
'Instruments and
Packs' (Fast Exhaust' or
'liquids'
(Slow
Exhaust).
4.
Set
Timer to 15 minutes. Cycle will go
to
completion automatically.
NOTE: CYCLE TIMER
