Introduction
As leaders in the field of sterilization, our goal is
to engineer and manufacture safe, efficient,
quality sterilization products. We are certain you
will agree that this sterilizer meets our goal.
Regardless of how well a piece of equipment is
designed, misuse, abuse, or neglect will deny its
owner the safe, efficient, quality service
expected. Often, misuse, abuse or neglect occurs
unintentionally because the operator is unaware
of the proper operating and maintenance
procedures. This manual provides you with the
information required to properly operate and
routinely maintain your sterilizer. The information
included in this manual applies to all models
unless noted for specific models.
We urge you to read this manual carefully before
operating the unit, and retain it for future
reference.
Operation Overview
Hydroclave MC8 and MC10
Steam Sterilizer
The MC8 and MC10 sterilizer operates on the
principle of heated water converted to steam in a
sealed pressure chamber.
What happens when the controls are turned
on?
• The chamber vent valve opens and the
heater turns on to warm up the chamber.
The items to be sterilized are placed on

5
the trays and the trays are placed
inside the sterilizer chamber. (Certain
parameters such as positioning and
size of the load must be observed for
proper operation and satisfactory
result.) Then, the door is closed and
latched, and the “START” button
pressed to start the cycle.
What happens when the cycle starts?
• The water fill valve opens and the
proper amount of water automatically
flows from the reservoir into the
chamber.
• The water in the chamber begins to
heat. As the water turns to steam, the
temperature and pressure increase,
forcing air from the chamber.
• When the temperature in the chamber
reaches the proper temperature (121
or 135°C) the exposure timer begins.
During this exposure time, the
temperature in the chamber is
automatically maintained at either 121
or 135°C, plus or minus about two
degrees.
• At the completion of the exposure time
a solenoid valve opens, allowing the
steam and water to vent back into the
reservoir. The steam reenters the
INTRODUCTION

6
reservoir through tubing below the water
level in the reservoir. The water in the
reservoir condenses the steam to a
liquid for reuse in the next cycle.
When the one minute timed vent is
complete an indicator light on the control
panel lights to alert the operator that the
cycle is complete.
Drying cycle
At the completion of the sterilization cycle, the
drying cycle automatically begins. This cycle
continues until the selected time has elapsed or
the door is opened.
To restart a drying cycle that has been terminated
by opening the door; close the door (DO NOT
LATCH) and press the “START” button.
Operator Maintenance
It is important to establish the maintenance
schedule called for in the Operator Maintenance
section of this manual.
Daily
Before each days use: Check the water level in
the reservoir. Refill with distilled or deionized
water if needed. Clean the door gasket and its
mating surface.
INTRODUCTION

7
Weekly
Clean the chamber, rack and trays once a week
to prevent a buildup of mineral deposits inside
the chamber. Normal tap water contains
chemicals and minerals, chlorine being the
most common. Chlorine is especially corrosive
to the stainless steel chamber, trays and rack
when water is turned to steam during the
sterilization process. It is important to remove
any mineral deposits regularly to ensure peak
operating efficiency.
Distilled or deionized water should always be
used in the MC8 and MC10 steam sterilizer.
Even when distilled or deionized water is used,
some contaminants can collect in the chamber,
rack and trays.
Clean the reservoir, reservoir filter and chamber
screen at least every 25 cycles. A clogged filter
and/or screen will result in restricted water flow
and prolong the time it takes to fill the chamber.
Maintaining a clean reservoir, filter and
chamber screen is especially important. Foreign
particles, such as bits of oil, adhesives,
amalgam, etc., can be picked up from items
being sterilized and returned to the reservoir,
clogging the filter and screen.
The daily and weekly maintenance should be
performed as outlined above to ensure long,
trouble-free service. Failure to routinely perform
maintenance procedures could result in
processing delays or equipment down time and
possible equipment repairs.
Detailed maintenance procedures for those
listed above and also other “as required” items
are shown in the Operator Maintenance
section of this manual.

Printer
The MC8 printer is a separate unit connected to
the sterilizer by a plug-in cable. The optional
MC10 printer is an integral part of the Control
Panel.
Non-Recirculating
Water Accessory
Standard MC8 and MC10 sterilizers discharge
steam back into the reservoir. For sterilizers with
the non-recirculating system, the distilled water is
used to make steam in the chamber for one cycle
only. Used water (steam) is exhausted into the
cooling tank which then overflows into the
collection bottle. The collection bottle is then
emptied when full.
An optional overflow tube is provided for
connection to the back of the cooling tank. This
feature allows the excess water to drain directly
into a sink or drain (if available), eliminating the
need to periodically empty the collection bottle.
Recommended Steam
Sterilization Monitoring Program
All functions of the sterilizer should be monitored
to provide maximum sterilization assurance.
The Joint Commission on Accreditation of
Hospitals and the American Dental Association
recommends that biological indicators be used at
least weekly to check the effectiveness of steam

sterilizers to sterilize; i.e., to kill test organisms
of a known high resistance. (Bacillus
stearothermophilus is the recommended test
organism for monitoring steam sterilization.)
We recommend the use of process indicators
such as the B T Check Indicator within each
package of each cycle. For additional
assurance that minimum sterilizing conditions
have been achieved, a biological indicator such
as B T Sure should be used at least once a
week.
