INTRODUCTION

A. Product Description:

The Market Forge Sterilmatic Sterilizer with Digital Controller (model STM-ED) is a compact, automatic, low cost
steam pressure sterilizer (autoclave).

The sterilizing cylinder is a 3/16” (4.8mm) thick wall, welded aluminum. The exterior is made of polished stainless
steel. Interior dimensions of 16” (406mm) diameter and 26” (660mm) long with a cubic content of 5,220 cubic
inches (0.085 cubic meters) and has a door opening of 13-1/2” (343mm) wide and 11” (279mm) high. The steril-

izing compartment has a pan capacity of:

□ (3) 12” x 20” x 2 ½” (305mm x 508mm x 64mm) or,
□ (2) 12” x 20” x 4” (305mm x 508mm x 102mm) or,
□ (1) 12” x 20” x 6” (305mm x 508mm x 152mm)

The sterilizer door is a self-sealing type that cannot be opened until the steam pressure is completely exhausted

from the chamber. The door is 12 gauge stainless steel and removable for cleaning without tools. The door gas-

ket is one-piece molded, also replaceable without tools or cement.

The sterilizing cycle is fully automatic with the time, temperature and venting controlled by the microprocessor
based, digital controller.

The sterilizing temperature can be set anywhere in a range from 225°F (107°C) and 250°F (121°C). There is an

on-board data logger/printer. The data logger records the time, temperature and pressure for each sterilization
cycle. This data can be stored for future printing or printed out following each cycle.

INTENDED USE - STERILIZATION CYCLE

This unit is intended to be operated intermittently.

After a pre-heat cycle, the longest period of steril­ization (heating) should be a maximum of 60 min-

utes. The digital timer allows up to 99 minutes, but
it should be kept at no more than 60 minutes. After
each use the unit should be opened for removal
and reloading of product. The water level should

be checked after each use and relled when nec-

essary.

INSTALLATION

Set sterilizer on counter, using the 6” (152mm) legs

provided or assemble the optional stainless steel stand
with under-shelf. If your Sterilmatic includes a water­cooled exhaust condenser, we recommend the use
of the Sterilmatic stand, part number 95-6060. First,

level unit in place, then adjust rear legs to pitch the unit

forward 1/4” (6mm) to insure positive drainage of the

cylinder.

ELECTRICAL

Connect to proper electrical supply box and disconnect

switch as shown on one of the following schematic dia­grams - 208 or 240 volts, single or three phase. Con-

nection is made from the rear of the unit, through the
conduit to the terminal box located at the front of the
unit. See installation specications on page 5.

OUTSIDE VENTING

Connect 1/2” (13mm) nominal tubing exhaust to out-

side vent connection located on top of unit, within 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.
Use 1/2” (13mm) copper tubing or suitable alternate.

The overall height and length of the line should not rise

more then 4 feet (1.2 meters) above the unit and ex­ceed 15 feet (4.5 meters) with a minimum of bends.
The line should slope downward after leaving the steril-

izer in order to insure condensate drainage.

WATER-COOLED EXHAUST CONDENSER

If outside venting is not possible, an optional water­cooled condenser is available for connection to an
open drain. If required order part no. 95-0436 kit.

TRAY SUPPORTS

Install side tray supports. Tray supports are attached
by means of key-hole clearance slots which are slipped

over studs located on the sides of the Sterilmatic cham-

ber.

BAFFLE INSTALLATION

To insure maximum drying of packs, a bafe is supplied
with your Sterilmatic. Place perforated splash bafe in
bottom of the sterilizing chamber. Install small bafe
with no perforation at the rear of the upper tray support

channel.

NOTE: The perforated bafe is not to be used as a

shelf to place media or other items. It is intended to
eliminate splashing.

OPERATION CHECK

To check for proper operation of unit:

Close drain valve by turning handle clockwise.

1.

WARNING: DO NOT OPEN DRAIN VALVE WHILE

UNIT IS OPERATING. PREMATURE OPENING
MAY RESULT IN SCALDING OF OPERATOR.

Fill chamber with 4 to 5 quarts (3.8 to 4.7 liters) of

2.

ordinary tap water. DO NOT USE DISTILLED OR

but must exit casing at B.

IMPORTANT: Exhaust line must be vented to the out­side to eliminate the exhaust steam and the accompa­nying noise from entering the room. Use 1/2” (13mm)

copper tubing or suitable alternate. The overall height

and length of the line should not rise more then 4’ (1.2
meters) above the unit and exceed 15’ (4.5 meters) with

a minimum of bends. The line should slope downward
after leaving the sterilizer in order to ensure condensate
drainage.

IMPORTANT: Failure to comply with this outline will af-

fect the sterilization process.

When an exhaust condenser is supplied; the following

services must be provided: 1/2” (13mm) IPS cold water:
1” (25mm) IPS waste: 115V electrical line.

SECTION 1 INSTALLATION INSTRUCTIONS

INSTRUCTIONS FOR INSTALLING PAN SUPPORTS AND BAFFLES

Locate the mounting studs on the inside of the chamber. There are two rack mounting studs on each side

1.
(see Fig. 1).

Taking one pan support and positioning rack so that the pan stop is facing the rear of the unit and the wires

2.

are facing toward the center of the unit. The pan stop is a piece of sheet metal welded to the rack with a 65° bend.

Begin to hang the pan support by placing the rear key-way slot onto the rear mounting stud and slide the rack

3.

until the slot sits on the mounting stud. When this is done correctly the front mounting stud will be in position

to place the front key-way slot. Slide the rack down into its correct position (see Fig 2).

After installing one pan support rack correctly, you can install the upper bafe. Position the bafe so that the

4.

45° bend is facing up towards the front of the unit (see Fig. 3). Slide the mounting tab onto the at bend on
the pan stop bracket. The bafe should now stay in place by itself, but in a tilted state (see Fig. 4).

Position the second pan support rack into the cavity and slide the other mounting tab onto the rack at bend

5.

while the pan support rack is not on the mounting studs. Hang the pan support by placing the rear key-way
slot onto the rear mounting stud and slide the rack until the slot sits on the mounting stud. When this is done
correctly the front mounting stud will be in position to place the front key-way slot. Slide the rack down into

its correct position.

Place the Perforated Water Bafe so that it sits on the bottom of the inside of the sterilizer chamber (see Fig. 5).

6.

CAUTION: Do not cover the holes in the Perforated Water Bafe by using it as a shelf. This will result in a

7.

disrupted ow of steam.

THE ELECTRIC SUPPLY CONNECTIONS FOR STM-ED: Connect to proper electrical supply as indicated on

nameplate on top of unit. The power supply cord is brought in from the rear of the unit, through the conduit and
the connection is made at the terminal box located at the front of the unit.

THE ELECTRIC SUPPLY CONNECTIONS FOR STM-EDX: Connect to proper electrical supply as indicated on

nameplate on top of unit. Connection is made from the rear of the unit, through the conduit to the terminal box
located at the front of the unit. All control circuits are 220 volts.

In order to accomplish this, a current-carrying grounded neutral must be provided.

Thus, a three phase system must be 4-wires. Most electrical codes require, and we recommend, that a separate
switch be located within sight of the sterilizer.
