Introduction
OPERATING ENVIRONMENTAL CONDITIONS
This unit is designed for commercial use and to be safe at
least under the following conditions:
• For indoor use only.
• For use at altitudes up to 6500 ft (2000 m)
• For use at temperatures from 41°F (5°C) to 104°F
(40°C).
• Maximum relative humidity 80% for temperatures up
to 88°F (31°C) decreasing linearly to 50% relative
humidity at 104°F (40°C).
• Main supply voltage uctuations not to exceed ±
10% of nominal voltage.
• Transient overvoltages according to Installation Cat-
egories II (in accordance with IEC 664).
• Pollution Degree 2 (in accordance with IEC 664).
INTENDED USE - DUTY CYCLE
This unit is intended to be operated intermittently. After a
pre-heat cycle, the longest period of use is 60 minutes.
The timer allows a maximum of 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 necessary.
SERVICE & TECHNICAL INFORMATION CONTACT
WARNING
This unit should be serviced by qualied ser-
vice personnel only.
Your Sterilmatic Sterilizer has been developed to answer
the need for a compact, automatic, low-cost steam pres-
sure sterilizer. The following instructions cover installa-
tion. 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 on our website, www.mi.com.
WATER CONDITIONS
Market Forge from time to time is asked the question
about using distilled or deionized water for use with our
Sterilizer models STM-E and STM-EL. We are always
asked why these water choices are not allowed for use
with our units and what would be recommended. To ad-
dress this situation, we have complied the following as a
means of satisfying these questions:
1. We have found that the use of distilled or deionized
water will aggressively attack the pure coat of Alumi-
num Alclad, which protects the bottom surface from
oxidizing and then eventually pitting (reference: Op-
erating and Maintenance Instructions).
2. In addition pitting can also be caused by several other
external environmental factors. Few examples are as
follows. These conditions have been highlighted in
our documentation.
• Grains of hardness in the water supply should
be as follows (.25 to 2).
• A pH imbalance in the water supply can greatly
affect the life to the aluminum cylinder. The pH
range that would be recommended is between
7.0-8.5.
• The lack of a positive electrical ground can
cause an electrolytic reaction that will accelerate
pitting.
• Another contribution to accelerate pitting is the
type of cleaning solutions used or the abrasive
scrubbing pads. If a low pH is present with the
detergents being used or an abrasive pad, the
protective Alclad coating will be removed during
the cleaning process.
• Spillage of media being sterilized can also con-
tribute to the accelerated pitting if it is corrosive.
• CHLORINE LEVEL ≤ 1 PPM.
IMPORTANT
Market Forge will not be responsible for dam-
age resulting from the use of hard or corro-
sive water, from failure to drain the unit daily,
or from inadequate cleaning procedures.
