For every sterilization / disinfection cycle_______________________________
4.1
Main switch, pre-heating of the chamber_____________________________________
At the beginning of one working day, press the main
switch to turn on the autoclave and select the
program if necessary. The autoclave's chamber will
automatically get pre-heated. During this heating
period (about 10...15 min. for sterilzation, and less
than 10 min. for disinfection), the lamp
„
READY“
(11) will flash. When the pre-heat temperature is
reached, the blinking sign changes to a continuous
light. Now the specified program can be started.
Once the pre-heat process has been finished, the
pre-heat temperature will be kept on a constant level
so that the autoclave can be used without
interruption until it is turned off.
It is recommended to keep the sliding door closed
during the pre-heat period. Thus the autoclave can
be used earlier due to less heat loss.
At the end of a working day, the power switch should
be pressed to turn the autoclave off.
4.2
Selection of program _____________________________________________________
The
„
SELECT“ button (15) on the control panel of
the autoclave is used to choose the desired
program. The program selected is then signalled on
the corresponding signal lamps (16, 17).
Before leaving the factory, the autoclave is set to
sterilization.
Each time that the autoclave is switched on by the
power switch (4), the program selection is the same
as that selected when the device was switched off.
The operator should select the desired program
as soon as possible after switching on the
electrical power.
If the autoclave
has been already
preheated
(the
„
READY“ lamp (11) glows), and
if
the program is only then switched from
„
Disinfection“ to
„
Sterilization“,
the autoclave will
run through a brief
reheating phase
of about
5
minutes. If the program is switched from
„
Sterilization“ to
„
Disinfection“ after preheating, then
the autoclave will run through a
cool-down
phase
for the pressure chamber, of up to 45 minutes (see
Section 4.1). During this reheating or cool-down
phase, the
„
READY“ (11) lamp will flash, and the
autoclave cannot be put into operation.
IMPORTANT:
•
Items for sterilization can also be sealed into
transparent sterilzation packages.
•
Steam pressure disinfection is permissible only for
instruments which are
unpacked
.
•
This autoclave cannot disinfect or sterilze liquids
or textiles.
•
Observe the instructions above on the reheating
and cool-down phase if the program is changed
between sterilization and disinfection after the
autoclave has been preheated.
4.3
Items to be sterilized _____________________________________________________
Carrier basket, instrument carrier
Never use the autoclave without one of the
specifically provided carriers. Otherwise a
malfunction may occur due to lack of ventilation or
blockage of a steam tube. For universal use of your
MELAquick
®
12, you have 3 possibilities:
•
For general purposes use the
insert basket
(part
No. 121). It provides a sterilization of 12 turbines
and contra-angles. Other instruments with a
maximum length of 16cm can be sterilized in this
basket, too. If you want to sterilize instruments
with very small size, e.g. endodonic instruments,
the basket has a half-rounded container which can
be hung either in a higher or lower position.
•
The
instrument carrier
(part No. 122) is fitted
with 7 ISO adapters that can be used with
instruments with ISO connectors. These
instruments can easily be sterilized in the
MELAquick
®
12
.
•
The
instrument carrier
(part No. 123) is fitted
with 7 round holders which can be used with
instruments whose manufacturers recommend a
sterilization with the instrument's head pointing
down.
Sterilization packages
The items to be sterilized can be sealed in a
transparent sterilization package like MELAfol
®
(one
side paper, one side film). For sealed items only use
the basket, order no. 121. It is important that you do
not place too many instruments in the basket. They
must be placed in a position where the incoming
steam can reach all paper sides of the sterilization
packages. When sealing the objects inside the
sterilization packages, make sure that the sealing
seam has a width of at least 8 mm in accordance
with DIN
58953, part. 7. The MELAG package
sealing device MELAseal
®
seals such plastic bags
with a sealing seam of 10 mm.
Temperature sensitive items
Especially plastic articles and turbines or
instruments with fibre optics are very sensitive to
high temperature. So look for the maximum
temperature to which the instruments can be
exposed, according to the manufacturer's
recommendations. Please refer to their specific
instructions. The regulation with microprocessors in
combination with highly sensitive sensors ensure
that the temperature in the chamber and its wall
never exceeds the maximum temperature of 135°C
for sterilization and 107°C for disinfection.
Liquids and textiles
The autoclave is not suitable for sterilization of
liquids or textiles!
