1. General
1.1 Introduction
Model LABSCI 15+L is a laboratory sterilizer designed especially for
the sterilization of instruments, liquids, and other materials in hospital
laboratories, laboratories & research institutes, food laboratories and
pharmaceutical facilities.
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.
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.
In BH (bio-hazard) models, a bio-hazard filter installed in the chamber
enables sterilizing bio-hazard load without contaminating the
surrounding.
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.

Page 7
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.
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.
Caution!
Only technical personnel having proper qualifications, holding
technical documentation and adequate test instrumentation are
authorized to undertake repair or service.
1.2 Incoming Inspection

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.
1. 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.
2. 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.
3. 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.
4. 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.
5. Never start using a new autoclave or a new steam generator, before
the safety, licensing and authorization department has approved it for
use.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. On closing the autoclave's door, make sure it is properly locked
before activating.

Page 11
12. Before withdrawing trays, wear heat resistant gloves.
13. Before opening the door, verify that there is no pressure in the
chamber (chamber pressure gauge is located on the autoclave's front
panel).
14. Open the door slowly to allow steam to escape and wait 5 minutes
before you remove the load. When sterilizing liquids, wait 10 minutes.
15. Once a month, ensure that the safety valves are functioning, and
once annually a certified tester must conduct pressure chamber
safety tests.
16. Once annually, or more frequently, effective tests must be performed,
i.e., calibration and validation.
17. Examine the condition of assemblies on a regular basis. Make sure
there are no leaks, breaks, blockages, whistles or strange noises.
18. It is required to conduct maintenance operations as instructed.
19. Immediately notify the person in charge of any deviation or risk for the
proper function of the device.

(DI) ions and charged particles are removed either by electric fields or
by ion exchange in resin beds.
Although the RO cannot normally attain the degree of purity possible
with the DI methods, it is more than adequate for the feed water
intended for clean-steam generators.
Moreover the RO has several advantages:
1. RO is cheaper to install and to run than DI.
2. RO removes particulate matter, organic molecules and pyrogens that
DI cannot remove
3. RO water is less corrosive to steel and copper than DI water.

4. RO maintenance requirements are less demanding than those of the
DI units.
Therefore the use of mineral free water will contribute to better
performance and longer life of the autoclave.
