4.2. DESCRIPTION OF THE WATER TANK
The sterilizer is equipped with 2 independent water tanks of equal volume - 3.5 litres (MB17) or 4,5 litres (MB22).
The left tank also called the "main tank" contains the distilled or demineralized water required for each cycle.
It is fitted with 2 level sensors, minimum (0.5 l) and maximum (3.5 l on MB17 or 4.5 l on MB22).
The right tank called the "used water tank" contains the used water collected at the end of each cycles.
It is fitted with a maximum level sensor (3.5 l on MB17 or 4.5 l on MB22).
The 2 tanks are connected to drain connections located behind the service door.
The water consumption per cycle varies depending on the type and mass of the sterilized load.
The following message is displayed on the screen when the minimum water level is reached in the main tank:
While the message is displayed, it is impossible to run another cycle.

4.3. FILLING OF THE MAIN WATER TANK
Remove the main water tank cap located on the top of the
sterilizer
…
…Fill the tank with approx. 3 litres on MB17 (or 4 litres on MB22) of water...
…Once the tank is almost full, an audible tone will be heard.
When you hear the tone proceed carefully. You must stop
filling as soon as the water level reaches the lower edge of the
opening to the water tank.
If the sterilizer is not used for more than 3 days, both water tanks must be
completely drained in order to avoid alga growth or any other deposits.
Attention !
Use only high quality distilled or demineralized water (see Annex 7).
The water from the main tank (3 litres on MB17 or 4 litres on MB22) has been used for a series of
cycles.
This water has been drained off and stored in the used water tank which will be full.
While the main tank is re-filled, the used water tank must be drained in the meantime (see § 4.4.).
