2. SAFETY INSTRUCTIONS

The autoclave has unique characteristics. Please read and understand
the operation instructions before first operation of the autoclave. This
manual includes instructions and guidance provided by the
manufacturer: how to operate the autoclave, the door safety
mechanism, and the dangers involved in circumventing safety means,
how to ensure that the door is closed, and how to select a correct
sterilization program.

Make sure that you know where the main power switch is located.

Autoclave maintenance is crucial for the correct and efficient function of
the device.

Never use the autoclave to sterilize corrosive products, such as: acids,
bases and phenols, volatile compounds or solutions such as ethanol,
methanol, chloroform or radioactive substances. Below are the
operating instructions – safety instructions:

1. All autoclave users must receive training in proper usage from an
experienced employee. Every new employee must undergo a
training period under an experienced employee.

2. When sterilizing plastic materials, refer to the item manufacture
information and make sure that the item can withstand the
sterilization temperature. Plastic that melts in the chamber is liable
to cause a great deal of damage.

3. On closing the device door, make sure it is properly locked before
activating. Verify that the DOOR OPEN symbol is replaced by
“System Ready”.

4. When withdrawing trays, use the enclosed tray handle or wear
heat resistant gloves.

5. The door is electronically locked and will not open unless the
pressure in the chamber equals the atmospheric pressure
(chamber pressure is displayed on the screen).

6. The door also remains locked if there is a cycle failure or the unit
has no power.

7. Open the door slowly to allow steam to escape.

8. Once a month, ensure that the safety valve is operating, and once
every 5 years a certified inspector must perform a chamber
pressure safety test.

9. Make sure there are no leaks, breaks, blockages, whistles or
strange noises.

10. Perform maintenance operations as instructed. The owner of the
autoclave is responsible to perform the maintenance operations.

11. Notify the person in charge immediately of any deviation from the
proper function of the device.

12. Protective equipment and clothes and other safety instructions
should be implemented in accordance with local and national
regulations and/or rules!

3. GENERAL INFORMATION

3.1. Introduction

The EZPlus tabletop autoclave is designed for sterilization of
wrapped and unwrapped instruments, and related items found in
dental, medical, and veterinary clinics, first aid rooms, hospitals,
laboratories etc.

This autoclave is an electrically – heated sterilizer using steam

as the sterilizing agent. This unit uses steam flush pressure

pulse technology for removing air from the chamber. A

computerized control unit ensures a fully automatic sterilization

cycle, control and monitoring of physical parameters and a clear

documentation of the sterilization cycle.

The autoclave offers a choice of four automatic programs and

two custom programs designed to match the material to be

sterilized. In addition there is a dedicated cleaning program. The

autoclave is equipped with an Air Assisted Drying system. This

includes an air pump that during the drying stage draws air

through a HEPA filter (0.2µm) and circulates that air through the

heated chamber to remove moisture and facilitate the drying

operation. Drying is performed with the door closed.

On all models, a water pump is installed between the water

reservoir and the chamber. This pump guarantees fast and

accurate filling of the chamber every time. Entry of water may be

accompanied by a noise for approximately 30 seconds. This is

normal noise generated by the regular operation of the pump.

The EZPlus series features a digital absolute pressure display
for monitoring and control purposes. The pressure display
indicates if there is pressure in the chamber. The device is
capable of displaying the pressure in psia, psig, or in kPa
according to the operator’s requirements. When the pressure is
displayed in psig, the atmospheric pressure is shown (at sea
level) as 0 psig. If the pressure is defined in psia or kPa the
absolute zero is displayed as “0” and the atmospheric pressure
is shown (at sea level) as 14.7 psia or 100 kPa respectively.

Note: This unit comes from the factory with the pressure
parameter set to display in psig.

The EZPlus can display temperature in ºF or ºC.

Note: The unit comes from the factory set to display
temperature in ºF.

Page 9

The control system is designed to meet the most current
sterilization standards to ensure efficacy, safety of personnel
and reliable operation. See sec. 3.9

A printer is an optional addition to the autoclave. The printer
prints the preset and actual parameters of the cycle
(temperature, time and pressure).

The EZPlus features built in memory to record up to 100
sterilization cycles. These can be reprinted on the optional
printer or exported to a USB device to be transferred to a PC.

The EZPlus has a built in Network Port for use with Tuttnauer’s
R.PC.R software when connected to your local network.

The R.PC.R software has been developed especially for the
Tuttnauer autoclaves.

This application will allow you to:

 Monitor up to 8 autoclaves
 Monitor the real time activity of any autoclave connected via

the network port.

 Manage the history files of the cycles run on your autoclave.

The history files can be downloaded either directly through a
physical connection to the network port or transferred
manually using a USB device.

 Store all the history of the processes that have been run on

your autoclave

 Track the parameter setting that have been used in each of

the cycles and stages run.

 Choose the style of the report to view; either graph, table, or a

print out

 All reports can be saved as a PDF.
 The graph style report offers the user an option to customize

the inputs and outputs used in the presentation.

For more information on the R.PC.R refer to the R.PC.R user
guide.

This manual is intended for the user and gives the user a
general understanding of the instrument and the best ways to
operate and take care of it in order to obtain effective results.

Before operating this autoclave read carefully this operation
manual. After reading this manual, operating the autoclave will
be easy. However since this instrument is built with high
technology sensitive components, no attempt should be made
by the user or any other unauthorized person to repair or
recalibrate it.

4.1.3. Data Center

The Data Center contains a USB port, a network port and an
optional printer.

 The USB port can be used to upload or download

software and settings and download cycle history for
transferring to a PC for storage or printing.

 The network port (located on the rear of the unit) can be

used to connect to a local network and download
information to Tuttnauer’s R.PC.R software.

The RPCR software has been developed especially for the
Tuttnauer autoclaves and is an excellent report generating tool.

This software will allow you to:

 Monitor up to 8 autoclaves
 Monitor the real time activity of any autoclave connected via

the network port.

Page 24

 Manage the history files of the cycles run on your autoclave.

The history files can be downloaded either directly through a
physical connection to the network port or transferred
manually using a USB device.

 Store all the history of the processes that have been run on

your autoclave

 Track the parameter settings that have been used in each of

the cycles and stages run.

 Choose the style of the report to view; either graph, table, or a

print out

 All reports can be saved as a PDF.
 The graph style report offers the user an option to customize

the inputs and outputs used in the presentation.

For more information on the R.PC.R refer to the R.PC.R user
guide.

 The printer is an optional device. It prints the detailed history of

each cycle performed by the autoclave. The printing is on
thermal paper with 24 characters per line and records the
sterilization cycle information for subsequent consideration.

4.2. Displayed Error Messages / Symbols

An error message is displayed when a failure occurs. The
failures are divided into two categories.

1. Failures that occur before completing the sterilization stage,

which in this case will leave the load unsterilized

2. Failures that occur after completing the sterilization stage,

which in this case will leave the load sterilized
