Note: Always have this machine’s model
and serial number (printed on the first page
of this document) ready when calling
Consolidated for service or parts.
WARNING
If this sterilizer’s chamber is constructed of Stainless
Steel, NEVER use CHLORIDE based cleaners to
clean this sterilizer. NEVER sterilize items containing
CHLORIDES or producing CHLORIDE GASES in
this sterilizer. CHLORIDES have proven to damage
the Stainless Steel material causing cracks and pin
holes, which will lead to steam leaks.

1. Introduction
The fully automatic Consolidated SSR and SR series of sterilizers are intended for use by
facilities to sterilize heat and moisture stable materials by means of pressurized steam.
These sterilizers are available in several different chamber sizes.
The Mark II control system continuously monitors and visually displays the relevant
temperature and pressures in the sterilizer. It also automatically initiates and controls
each phase of the sterilization cycle -- condition, sterilize, and exhaust -- for greater
assurance of sterilization.
Our sterilizers can either be supplied for connection to direct building steam supply of
50-80 PSI of pressure, or come equipped with an integral, electrically heated steam
generator. The Mark II controls are identical for both types.
Consolidated sterilizers have been on the market since 1948 and enjoy an excellent
reputation for quality and reliability. One of our design goals is to use off-the-shelf
components on our machines whenever possible to minimize down time and service costs
to our valued customers. Most of the solenoids, valves, and steam-traps used in our
machines are available from your local service representative.
Many optional items, such as automatic jacket and generator blow-down are available
with the Mark II control system. Specialized sterilization cycles, such as low-
temperature sterilization are also available.

1.1 Safety Instructions
The following safety instructions appear in this manual. Please read them carefully
before operating the sterilizer.
1.1.1 Aborting a Cycle
WARNING: RISK OF NON-
STERILE DEVICE
Please note that if a cycle is aborted prior to successful termination, it must
be considered incomplete and the load must be reprocessed (unwrapped
goods or liquids) or repacked and reprocessed (wrapped goods).
The MKII Controller Operator’s Guide

To abort a cycle in progress, press the red POWER key on the keypad assembly.
This will shut off power to the unit. You will then need to open the green–handled
manual exhaust valve (labeled Manual Steam Exhaust Valve) visible by removing
the access panel below the chamber door. Wait for the pressure inside the chamber
to reach atmosphere before carefully opening the door.
1.1.2 Starting a Cycle
WARNING: BURN HAZARD
The operator MUST wear protective clothing including face shield, thermal gloves,
and proper lab attire, when attempting to load and unload the chamber materials.
Steam released from the sterilizer chamber can cause serious burns. Stand away
while opening the door.
If water leaks from the front of the sterilizer, DO NOT open the door. Contact
service personnel.
!
!

To start a cycle, make sure the door is hand-tight. Press the appropriate selector switch
for the type of cycle you are running (Fast, Dry, or Fluids), then press the red power
button on the selector switch to start the cycle. See section 6 for a complete tutorial
before you start operating the machine.
1.1.3 Preparing the Load
WARNING: RISK OF
INFECTION
Please note that airborne microbial and particulate contamination is likely to
be high in the decontamination area of the sterile processing department.
Users MUST wear protective clothing and equipment when preparing goods
for sterilization or when in the decontamination area.
!
Please see section 7.2 on load preparation before you start operating the machine.
1.1.4 Sterilizing Fluids
WARNING: INJURY
HAZARD
If the wrong cycle is selected to sterilize liquids, the containers may burst
or crack during the processing.
After completion of a FLUIDS cycle, take care that you do not agitate the
fluids during removal from the chamber. Otherwise the containers may
burst or crack.
!
WARNING!
Sterilized liquids are not intended for direct patient contact.
!
Please see Section 3.3 on Sterilizing Fluids.

2. Overview of the Mark II Controller
The Mark II is a simple, easy-to-operate sterilizer control system. It allows selection of
sterilizer cycles, setting of temperature, and times for Sterilization and Dry. It displays
status of the machine in sterilize or exhaust modes, executes selected cycles, and prints a
chart of sterilizer temperature vs. time. Figure 2.1 shows a typical Mark II controller
with a chart recorder.

2.1 Description
The Mark II controller was designed with simplicity of operation in mind. The controller
allows setting of sterilization time and dry time (for a Dry cycle only). LEDs on the
controller show when the machine is in the sterilize mode and when it is in the exhaust
mode. A selector switch (see Figure 2.1) allows user to select one of three types of
cycles: Fast, Fluid, & Dry. A pressure gauge shows the current steam pressure inside the
chamber of the sterilizer. A chart recorder records a graph of time vs. temperature during
the cycle. For Low-Temp equipped sterilizers, please see section 4.3.

2.2 Chamber Pressure Gauge
The chamber pressure gauge shows the steam pressure in the chamber at all times. Make
sure this gauge registers zero before you attempt to open the door.
2.3 Circuit Breaker
The circuit breaker’s purpose is to protect the electronics. If the circuit breaker cuts off
the power to the sterilizer, a qualified technician needs to troubleshoot the source of the
problem before resetting it.
2.4 Cycle Selector Switch
You can choose the type of cycle you want to run with the cycle selector switch. The
cycle selector switch also acts as the ON/OFF button for the sterilizer. See section 3 on
Selector Switch operation.
2.5 Jacket Reset Button and Light
When the green Jacket Light (see Figure 2.1) comes on, you need to press the Jacket
Reset Button and wait for the jacket pressure to build up before you can start a new cycle.
2.6 MKII Controller
You can set the sterilizer and exhaust (in case of a Dry cycle) time and view the
remaining time on the MKII controller. See section 4 for more information.
2.7 Chart Recorder
The chart recorder offers a chart of time vs. temperature for your sterilization cycle. You
can also set the temperature for your sterilization cycle on the chart recorder. See section
5 for more information.
