regarded as unsterile.
The required protocol will also be printed out in this
case. See Section 1.5.
4.10 Removal of instruments __________________________________________________
When the pressure is 0 bar and the lamp "END"
lights, the chamber can be opened.
To unlock the
sliding door turn the knob 90° counter-clockwise.
Shortly before the end of the turn, you have to
overcome a slight resistance before the door is
completely unlocked.
You can see the lamp "END" (13) go out while lamp
"READY" (11) is lighting again. The autoclave is now
ready for a new start.
If the sliding door cannot be completely unlocked,
there is still pressure in the chamber which is
produced by post-vaporization. Then the pressure
operated safety lock is still in operation. In this case,
lock the door once again and wait for a few seconds
until the pressure on the gauge (5) has fallen to
0 bar. Now unlock the door and pull the knob (2)
without pressing
it down.
4.11 Drying _________________________________________________________________
After sterilization,
unsealed sterilization items
are
dry and can be taken out immediately.
Sealed items or items to be disinfected
should be
left in the hot chamber for a few minutes with the
sliding door open. This is recommended for
complete drying.
4.12
Particuliarities of the disinfection___________________________________________
Packing
Items must not be wrapped.
Selection of the program
The operator must use the
„
SELECT“ button (15) on
the control panel to switch from sterilization to the
disinfection program. Then the signal lamp for
„
sterilization“ (16) will go out, and the lamp for
„
disinfection“ (17) will glow.
Cool-down phase
If the autoclave is set to the sterilization program, if it
is fully heated up, and if it is then switched to the
disinfection program, the
„
READY“ (11) lamp will
flash up to 45 minutes, until the autoclave cools
down to the preheating temperature for disinfection.
Also see section 1.3. During this period, it is not
possible to start the disinfection program.
4.13 Overheat
protection ______________________________________________________
Overheat excluded
Overheat during error-free process is generally
excluded due to the concept of separate steam
generation in combination with electronic-parametric
regulation. The limit of 135°C (107°C) cannot be
exceeded.
Steam temperature control
Additionally, the temperature of steam is
electronically controlled. If the limit temperature of
140°C (112°C) is exceeded owing to a defect, the
running program will also be interrupted, and the
„
FAULT“ lamp (10) will glow.
Temperature limitation
To avoid (e.g. complete failure of electronic / heater
cut-out) possible overheats and thus endangering
the items to be sterilized even under unusual
conditions, the autoclave has two separate
temperature limitors, one for the chamber and one
for the steam generator. These two work
independently from the safety system described
above and will directly cut power if temperature
exceeds the limit. If the temperature monitor system
triggers, the respective heating system will be
switched off, and the water pump will simulanteously
start to cool the steam generator. If the electronic
system is functional, the lamp
„
FAULT“ (10) will also
glow, indicating a fault.
Interruption of the sterilization
The light of lamp "FAULT" shows in every case that
the sterilization/disinfection program was not fully
completed. The items have to be considered as
unsterile.
When the “FAULT” light blinks (time is beyond limit)
and goes out if the door is opened, the sterilizing
conditions were not achieved fast enough or did not
remain long enough. The autoclave returns to ready
state after having opened the door. After having
checked the apparatus and removed the cause of
fault (too much load / ventilation holes blocked by
load / sliding door not tight because of improper
closing), you are able to continue your work
immediately with the autoclave.
If the fault message cannot be removed by opening
the sliding door, you either have tried to open the
door during the process or there is a defect in the
apparatus (heating elements / temperature sensors).
After switching off the main switch briefly (at least
10 seconds), the autoclave should be ready again.
For repeated fault messages, the cause of failure
must be found and removed by a service technician;
also pay attention to chapter 8.
