1GENERAL
Read the Operating Instructions carefully, before beginning any operation on
the autoclave!
1.1 Incoming Inspection
The autoclave should be unpacked and inspected for mechanical damage
upon receipt. Observe packing method and retain packing materials until the
unit has been inspected. Mechanical inspection involves checking for signs
of physical damage such as: scratched panel surfaces, broken knobs, etc.
If damage is apparent, contact your dealer or point of purchase, so that they
may notify the manufacturer and file a claim with the appropriate carrier.
All Tuttnauer products are carefully inspected prior to shipment and all
reasonable precautions are taken in preparing them for shipment to assure
safe arrival at their destination.
1.2 Warranty
We certify that this instrument is guaranteed to be free from defects in
material and workmanship for one year against faulty components and
assembly with the exception of the heaters.
The warranty does not include and does not replace routine treatment
and preventive maintenance to be performed according to instructions
in sec. 1 .1 (Preventive and Scheduled Maintenance).
Our obligation is limited to replacing the instrument or parts, after our
examination, if within one year after the date of shipment they prove to be
defective. This warranty does not apply to any instrument that has been
subjected to misuse, neglect, accident or improper installation or
application, nor shall it extend to products that have been repaired or altered
outside the factory without prior authorization from us.
The Autoclave should not be used in a manner not described in this
manual!
1.3 Warranty Statement
The warranty registration must be completed and returned to our service
departments; within fourteen (14) days of purchase or the warranty will be
void.

Note:
If there is any difficulty with this instrument, and the solution is not
covered in this manual, contact our representative or us first. Do not
attempt to service this instrument yourself. Describe the difficulty as
clearly as possible so we may be able to diagnose the problem and provide
a prompt solution.
If the autoclave is equipped with a printer, send along a copy of the last
printout for our inspection. If replacement parts are needed, stipulate the
model and serial number of the machine.
No autoclaves will be accepted for repair without proper authorization from
us. All transportation charges must be paid both ways by the owner. This
warranty will be void if the unit is not purchased from an authorized full
service Tuttnauer dealer.

2SAFETY INSTRUCTIONS
The autoclave has unique characteristics. Please read and understand the operation
instructions before first operation of the autoclave. The following issues may
require instructions guidance provided by the manufacturer: how to operate the
autoclave, the door safety mechanism, 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, where the water cut-off
valve is and where the compressed air disconnection valve is located.
Autoclave maintenance is crucial for the correct and efficient function of the
device. We enclose a log booklet that includes maintenance recommendations,
with every device.
The weekly spore test is part of the preventive maintenance plan, along with the
annual validation of the sterilization processes that ensures appropriate
temperature dispersion within the chamber.
Never use the autoclave to sterilize corrosive products, such as: acids, bases and
phenols, volatile compounds or solutions such ethanol, methanol or chloroform
nor radioactive substances.
1. Never start using a new autoclave or a new steam generator, before the
safety, licensing and authorization department has approved it for use.
2. 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.
3. A written procedure must be established for autoclave operation,
including: daily safety tests, seal inspection and door hinge inspection,
smooth action of the closing mechanism, chamber cleaning, prevention of
clogging and preservation from corrosion, what is permitted and what is
prohibited for sterilization and choosing a sterilization program.
4. Liquids may be sterilized only with the “liquids”program. The container
must be covered but not sealed. Sealed bottles may only be sterilized using
a special program. The bottle must be either Pyrex or a Borosilicate glass
bottle.
5. When sterilizing plastic materials, make sure that the item can withstand
sterilization temperature. Plastic that melts in the chamber is liable to
cause a great deal of damage.
6. Individual glass bottles may be placed within an appropriate container that
will be placed on a tray. Never place glass bottles on the floor of the
autoclave. Never fill more than 2/3 of the bottle volume.
7. On closing the autoclave's door, make sure it is properly locked before
activating.
8. Before withdrawing trays, wear heat resistant gloves.
9. Before opening the door, verify that there is no pressure in the chamber.
10. Open the door slowly to allow steam to escape and wait 5 minutes before
you remove the load. When sterilizing liquids, wait 10 minutes.
11. Once a month, ensure that the safety valves are functioning, and once
annually a certified tester must conduct pressure chamber safety tests.

Page 8 of 77
12. Once annually, or more frequently, effective tests must be performed, i.e.,
calibration and validation.
13. Examine the condition of assemblies on a regular basis. Make sure there
are no leaks, breaks, blockages, whistles or strange noises.
14. It is required to conduct maintenance operations as instructed.
15. Immediately notify the person in charge of any deviation or risk for the
proper function of the device.

3TECHNICAL DATA
3.1 Introduction
Model 2840 ELC is a table-top sterilizer designed especially for the
sterilization of instruments, liquids, and other materials in hospital
laboratories, medical laboratories, research institutes, food laboratories and
pharmaceutical facilities.
A computerized control unit ensuring a fully automatic sterilization cycle
controls the autoclave.
The temperature and pressure are controlled through sensors placed inside
and outside the media container or bottles.
A special feature of the ELC series is the option of a fast cooling stage for
liquids. In this stage pressure in the chamber is increased by means of
compressed air to compensate the fast decreasing of pressure due to the
fast cooling. The fast cooling shortens the time required for safe handling
of bottles.
Five automatic sterilization programs are available, according to the
material to be sterilized.
The sterilizer has multiple built - in safety devices, which provides
adequate protection to ensure the safety of operating personnel.
On all models, a printer is an optional addition to the autoclave. The
printer prints the preset and actual parameters of the cycle (temperature,
time and pressure/vacuum).
The pressure scale, printer option and cooling method can be set up at any
time by a technician.
NOTE:
After operating the sterilizer, brown stains might appear on the bottom of
the chamber. These stains are a result of the heating elements that are
located at the lower external part of the chamber. The brown color is a
common phenomenon, can easily be removed, and will not have any effect
on the sterilized goods.
This manual is intended to give the user a general understanding of how
the autoclave works and indicates the best ways to operate and take care of
it in order to obtain optimum results and a trouble-free operation. After
reading this manual, operating the autoclave should be straightforward.
However, since the autoclave is built using high technology sensitive
components, no attempt should be made by the user or any other
unauthorized person to repair or recalibrate it.
Only technical personnel having proper qualifications, holding
technical documentation and adequate test instrumentation are
authorized to undertake repair or service.

conditions!
3.3 Operating Conditions
This device is for indoor use only!

The autoclave shall not be used in a manner not specified in this
manual!
Do not use the autoclave in the presence of dangerous gases.
Operate the autoclave only in the manner specified in the manual. If
the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
