2 SAFETY 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 valves (if applicable) 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 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 in a basket. 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 baskets, wear heat resistant gloves.
9. Before opening the door, verify that there is no pressure in the chamber
(chamber pressure gauge is located on the autoclave's front panel or door,
depends on model).
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.
Page 6 of 58 Pages
11. Once a month, ensure that the safety valves are functioning, and once
annually a certified tester must conduct pressure chamber safety tests.
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.

3 TECHNICAL DATA
3.1 Introduction
Models 2540, 3150, 3170, 3850, 3870, 5050 and 5075, 5090 ELV are
vertical sterilizers designed especially for sterilization of instruments,
liquids and other materials in hospital laboratories, medical laboratories,
research institutes, food laboratories and pharmaceutical facilities.
A special feature of this sterilizer is the fast cooling operation, provided as
an option for the liquids sterilization cycle.
The sterilizer is fully automatic with a choice of six programs, eliminating
any need for operator intervention during a cycle. The sixth program is an
optional program including a cooling stage (program 7 is for leakage test
only). A computerized control unit enables precise control and monitoring
of physical parameters and clear documentation of the sterilization cycles.
The autoclave is equipped with a safety valve, which blows off at an
overpressure of over 25 psi, which is located on the rear of the autoclave.
The control system provides adequate protection, to ensure the safety of
personnel and reliable operation with a minimum of down time.
On all models (except 1730), 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 autoclave is equipped with a pressure gauge designed for reference
only. In case that there is any problem with electricity supply during a
sterilization cycle the pressure gauge will be used to verify that there is
pressure in the chamber.
This manual provides information for the following models:
ELV – this is the basic model of the vertical laboratory autoclave.
ELVC – this model includes a cooling system that enables cycles with
fast cooling.
ELVPRC – this model includes only the cooling coil as a preparation
for a cooling system but performs as ELV. A Tuttnauer technician can
upgrade this model to ELVC.
This manual is intended to give the user a general understanding of how
the autoclave works and indicates best ways to operate and maintain it in
order to obtain optimum results and a trouble free operation.
After reading this manual, operating the autoclave should be straight
forward. 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 re-calibrate it.
Only technical personnel having proper qualifications, holding technical
documentation and adequate test instrumentation, are authorized to
undertake repair or service.
