Sterilizer Features
Printer
This feature (available on some models) is a
thermal printer that record's each cycle's
performance. See page 40 for more information.
Pressure Monitor
The pressure monitor indicates the pressure inside
the chamber. This monitor's readings can be found
on the display as each cycle is running.
Door Security
While the chamber is under pressure, the door is
held securely closed with three separate locking
systems. First, there is a locking handle that you
must tighten to hold the door fully closed. The
locking handle turns clockwise to close and
counterclockwise to open. Second, there is a
pressure actuated locking pin which automatically
secures the door, preventing it from being
inadvertently opened while there is pressure in the
chamber. Finally, there is a backup catch which will
prevent the door from opening fully even if there is
a small amount of pressure in the chamber. You
release this catch with a lever which is located in
the lower left side of the door. To fully open the
door, pull the door release lever toward you.

15
Door Switch
Actuated by the door, the door switch prevents
operation of the sterilizer if the door is not fully
closed.
Pressure Relief Valve
This valve protects the coded vessel from
pressures exceeding the pressure rating of the
vessel. The valve opens and releases steam in the
event that pressure in the vessel exceeds 45 PSIG
(310 kPa). The pressure line is located in the back
of the unit. An access hole is located in the back
panel to allow you to periodically check relief valve
operation.
Reservoir Drain
Adrain assembly is provided to empty the
reservoir. The reservoir drain assembly and plug
are located at the lower right of the chamber
opening on the front of the sterilizer (as you face
the unit). The drain assembly attaches to the drain
connector so a hose can be attached for draining
the sterilizer reservoir into a container.
Trays and Tray Rack
Arack for the inside of the sterilizer is provided to
hold the instrument trays. The rack slides out of the
chamber to allow periodic cleaning of the chamber
and rack.
Three large trays and one small tray can be
placed into the rack or the rack can be used with
only one or two trays or no trays. Tall items can be
sterilized by removing both trays and placing the
objects on the bottom surface of the rack. One
large and one small tray are provided with the unit.
See "Loading the Sterilizer Chamber" on page 31
of this manual.
DESCRIPTION
Warning
Pressurized steam will be
discharged when the relief
valve is opened. To prevent
burns, wear gloves or use
an extension device if it
becomes necessary to oper-
ate the pull ring.

16
