4. INSTALLATION, PLACING AND LEVELING INSTRUCTIONS
Network
Network and connection should comply with the devices
consumption. It must comply with local installation and safety rules
and regulations. The voltage supplied to the device must comply
with the label ± 5%.
Caution:
The sterilizer must be placed on a rigid and leveled surface. The
stand must be able to hold the load of the device and loaded
material.
Note:
Make sure while placing the autoclave, to leave space around the
machine, to give the technician access to service the machine.
In order to avoid any injury by electrical hazard, it is mandatory for the
customer to have installed an earth leakage relay in the electrical board to
which the autoclave is connected.
This relay disconnects all the poles of the electrical power line in case of
accidental contact with the instrument metal enclosure, by the operator or
another person, leading to a dangerous leakage current.
Note: Keep the back and the right side of the autoclave approximately 1”
(25mm) away from the wall to allow for ventilation.
Connect the power cord to the socket on the rear side of the autoclave; plug it
into the supply socket.
4.1 leveling
The legs (2) of the autoclave are factory set for the autoclave to hold
this amount of water when the autoclave stands on a level surface (3).
To check the water level fill a beaker (4) with the recommended
quantity of water, pour the water into the chamber. The water must
reach the indicator groove (1) in front of the chamber.

Attention:
We recommend testing the water quality once a month. The use of water for
autoclaves that does not comply with the table above may have severe impact
on the working life of the sterilizer and can invalidate the manufacturer’s
guarantee.
Page 15 of 63 Pages
6. PREPARATION BEFORE STERILIZATION
The purpose of packaging and wrapping of items for sterilization is to provide
an effective barrier against sources of potential contamination in order to
maintain sterility and to permit aseptic removal of the contents of the pack.
Packaging and wrapping materials should permit the removal of air from the
pack, penetration of the sterilizing water vapor into the pack and removal of
the sterilizing vapor.
The basic principle determining the size, mass and contents of instrument and
hollowware packs is that the contents are sterile and dry immediately on
completion of the drying cycle and removal of the pack from the sterilizer
chamber.
Instruments to be sterilized must be clean, free from any residual matter, such
as debris, blood, pads or any other material. Such substances may cause
damage to the contents being sterilized and to the sterilizer.
1. Immediately after use, clean instruments thoroughly to dispose of any
residue.
2. It is recommended to wash instruments with an ultrasonic cleaner, using
detergent and mineral-free water.
3. Launder textile wraps prior to reuse.
4. After cleaning, rinse instruments for 30 seconds. (Follow manufacturer’s
instructions on the use of products for cleaning and lubricating
instruments after using the ultrasonic cleaner).
5. Materials, including materials used for inner wraps, shall be compatible
with the item being packed and the sterilizing method selected.
6. Do not place materials to be sterilized directly on the chamber’s wall.
Place the material only on trays, rack, etc.
7. Before placing an instrument into the sterilizer tray, make sure that
instruments which are not of the same metal, (stainless steel, carbon
steel, etc.) are separated and placed on different trays.
Note: Check manufacturer’s instructions for the sterilization of each
item.
8. In case carbon steel instruments are placed on stainless steel trays, the
trays should be lined with a towel or paper wrap before placing the
instruments on the trays. There should be no direct contact between the
carbon steel and the stainless steel trays.
9. All instruments must be sterilized in an open position.
10. Use single-use wraps once only and discard after use.
Page 16 of 63 Pages
11. Verify that the packaging method is in accordance with good practice
approach and the packaging materials are in accordance with the
applicable standards (e.g. EN868 series).
12. Place a sterilization indicator strip in each tray.
13. Place instruments with ratchets opened and unlocked or clipped on the
first ratchet position.
14. Disassemble or sufficiently loosen multiple-part instruments prior to
packaging to permit the sterilizing agent to come into contact with all
parts of the instrument.
15. Tilt on edge items prone to entrap air and moisture, e.g. hollowware, so
that only minimal resistance to air removal, the steam passage and
condensate will be met.
16. Load items within the boundaries of the tray so that they do not touch
the chamber walls, or fall off when the loaded car is inserted into the
autoclave.
17. The operator may use racks to allow for adequate separation of packaged
instruments.
18. Load trays loosely to capacity.
19. Once a week, use a biological spore test indicator in any load to make
sure sterilization is performed.
20. Make sure that all instruments remain apart during the sterilization cycle.
21. Empty canisters should be placed upside-down, in order to prevent
accumulation of water.
22. Allow a distance of approximately 2.5 cm (1”) between trays to permit
steam circulation.
23. Wrapped Instruments
Wrapped instruments should be packed in material that promotes drying
such as autoclave bag, autoclave paper, and muslin towels.
It is highly recommended to utilize the Tuttnauer Pouch Rack. This
rack allows the operator to place pouches on their side, thus increasing
the capacity of the autoclave significantly and promoting better drying of
the instruments. Contact your dealer for details.
Note:
A table “Suitability of steam sterilization processes for various goods and
method of packing” is added to the accompanying documents.
Pouch Rack
Page 17 of 63 Pages
24. Packs
1. Place packs upright on trays, side by side.
2. Packs should not touch the chamber walls.
3. Pack instrument sets in a manner that prevents damage to delicate
items.
4. Pack hollowware sets so that all openings face the same direction
and so that the contents cannot move inside the pack.
5. Load packs of folded operating room drapes with layers vertical,
allowing air to be removed from the packs rapidly.
6. Do not place packs of hollowware and trays of instruments above
textile packs or soft goods in order to avoid wetting caused by
condensation from items above.
7. Load items packed in flexible packaging materials on edge with
paper to laminate, or flat with the paper surface downwards.
Note:
The manufacturer’s recommendations shall be observed, concerning
the sterilization data for each type of material.
25. Tubing
When placing in a tray, make sure that both ends are open, without sharp
bends or twists.

26. Liquids
Use only heat-proof glass, filled to 2/3 capacity. Ensure that the glass
container is covered, but not sealed to prevent pressure build-up.
Note: A table of suitability steam sterilization process for various
goods and methods of packing is included with accompanying
documents.
