Introduction
As leaders in the field of sterilization, our goal is to engi-
neer 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, effi-
cient, quality service expected. Often, misuse, abuse or
neglect occurs unintentionally because the operator is
unaware of the proper operating and maintenance proce-
dures. 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 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 op-
eration and satisfactory result.) Then, the door is
closed and latched, and the “START” button
pressed to start the cycle.

5
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 cham-
ber.
•When the temperature in the chamber reach-
es 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 sole-
noid valve opens, allowing the steam and
water to vent back into the reservoir. The
steam reenters the 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 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 reser-
voir. Refill with distilled or deionized water if needed. Clean
the door gasket and its mating surface.
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 impor-
tant 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 steril-
izer by a plug-in cable and a separate power supply. 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 ex-
hausted 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 biologi-
cal indicators be used at least weekly to check the effec-
tiveness of steam sterilizers to sterilize; i.e., to kill test
organisms of a known high resistance. (Bacillus stearother-
mophilus 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.
