8 OPERATION
8.1 Operating Instructions
1. Verify that the mineral free water supply is connected to the mineral
free water inlet.
NOTE: The electrical conductivity of the water must not exceed
15 micro-siemens.
2. Load the chamber or the basket (optional accessory) with the materials
that to be sterilized.
3. If liquids are being sterilized, insert the temperature probe into one of
the bottles with liquid. If other materials are being sterilized, let the
probe hang freely in the chamber.
4. Close the door, proceeding as follows:
Models 2540, 3150, 3170, 3850 and 3870 are equipped with a side
closing mechanism. To close the door, lift the handle of the tightening
bolt in vertical position, then rotate it clockwise, until the bolt is hand
tight.
Models 5050 and 5075 are equipped with a central closing system. To
close the door, turn the handle clockwise, until radial arms are locked.
The “
DOOR CLOSED“ light is turned OFF, indicating the door is
closed and autoclave is ready for operation. Once the sterilization cycle
is in progress, a safety device locks the door and makes it impossible to
open it until completion of the cycle.
NOTE: (Except for models 5050, 5075)
Due to the inherent elasticity of the door gasket, the
CLOSE DOOR indicator light may be turned offbefore a
complete seal is made between the door and the chamber.
In order to ensure the door is fully sealed, when the Door
light has been turned off continue to tighten the door
bolt until “hand-tight”. Do not over-tighten the bolt as
this may result in damage to the gasket.
Should the autoclave fail to reach sterilizing
temperature/pressure, always check first that the door is
fully sealed. If not, tighten the door bolt further, as
described above, until a complete seal is made.
5. Turn on the main power switch located at the bottom of the front right
corner of the panel, to power the electric system of the autoclave.
6. Set the clock if necessary for the correct date and time, by means of the
keys
PROGRAM, UP and DOWN, as indicated in Chapter 4.1,
‘Description and Functions of the Keyboard’.
7. Select the required program by means of the key
SEL. CYCLE.
Pressing the
PARAMETERS key, the main parameters of the selected
program,
STER. TEMPERATURE and STER. TIME will be
displayed for 3 seconds.
