1General
Read the Operating Instructions carefully, before beginning any
operation on the autoclave!
1.1 Introduction
Model 5050/5075 EL-MD/EL-D is a laboratory sterilizer designed
especially for the sterilization of instruments, liquids, and other
materials in hospital laboratories, medical laboratories (including the
medical waste), research institutes, food laboratories and
pharmaceutical facilities.
MD models have a manual door with handle, and D models have an
automatic door equipped with an electrical cylinder. The automatic door
locks itself when closed and unlocks.by pressing a button.
The PV (pre-vacuum) models are equipped with a vacuum pump.
The advantages of the pre-vacuum sterilizer in comparison to the
regular gravity displacement steam sterilizer are as follows:
•Removal of air pockets from packs and porous loads and most
kinds of tubes (rubber, plastic etc.) by vacuum at the first stage
of the cycle.
•Better steam penetration into the load; resulting in effective
sterilization.
•Better temperature uniformity.
•Better drying of materials with closed doors due to the vacuum
achieved in the chamber at the end of the sterilization cycle.
In BH (bio-hazard) models, a bio-hazard filter installed in the chamber
enables sterilizing bio-hazard load without contaminating the
surrounding.
There is a configuration equipped with fan that allows shortening the
cooling operation.
The temperature and pressure are controlled through sensors placed
inside and outside the media container or bottles.
The autoclave is equipped with A 9Kw generator that produces the
steam required for the sterilization.

A special feature of the autoclave is 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.
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.
The sterilizer is fully automatic with a choice of 15 programs,
eliminating any need for operator intervention during a cycle (programs
9-10 are for vacuum testing 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 will discharge at
an overpressure of over 2.8 Bar (40 psi), which is located on the
chamber near the pressure switch and the steam pressure gauge. The
control system provides adequate protection, to ensure the safety of
personnel and reliable operation with a minimum of down time.
The sterilizer has multiple built-in safety devices, which provides
adequate protection to ensure the safety of operating personnel.
The printer prints the preset and actual parameters of the cycle
(temperature, time and pressure).
The autoclave is provided with a pressure gauge that is used as guide
only. Should there be a power failure during the operation of the
autoclave, the pressure gauge indicates to the operator that there is
pressure in the chamber.
A deviation of +1.6% is accepted.
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.

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 steam and compressed air
disconnection valves are 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.
Never start using a new autoclave or a new steam generator, before
the safety, licensing and authorization department has approved it for
use.
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.
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.
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.
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.
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.
On closing the autoclave's door, make sure it is properly locked before
activating.

Before withdrawing trays, wear heat resistant gloves.
Before opening the door, verify that there is no pressure in the
chamber (chamber pressure gauge is located on the autoclave's front
panel).
Open the door slowly to allow steam to escape and wait 5 minutes
before you remove the load. When sterilizing liquids, wait 10 minutes.
Once a month, ensure that the safety valves are functioning, and once
annually a certified tester must conduct pressure chamber safety tests.
Once annually, or more frequently, effective tests must be performed,
i.e., calibration and validation.
Examine the condition of assemblies on a regular basis. Make sure
there are no leaks, breaks, blockages, whistles, or strange noises.
It is required to conduct maintenance operations as instructed.
Immediately notify the person in charge of any deviation or risk for the
proper function of the device.
