3.4DESCRIPTION OF THE INTERNAL WATER TANKS

The sterilizer is equipped with two independent water tanks, one for clean water and one for used water (capacity of 3.5 litres each).

The tank on the right side is called "clean water tank" and has to be filled with distilled or demineralized water required for the sterilization process. It is fitted with a minimum (0.6l) and a maximum (3.5l) water level sensor. The tank can be filled manually through the tank hole on the top of the sterilizer or automatically with an external water supply system (Dem 32 or Osmo) connected to point D2 at the back of the sterilizer (see § 4.5.1).

Use the quick connector behind the service door (left/blue) to drain the clean water tank for cleaning purposes (see chapter on maintenance).

The tank on the left side is called "used water tank" and contains the used water collected at the end of each sterilization cycle. It is fitted with a maximum water level sensor (3.5l).

Use the quick connector behind the service door (right/grey) to drain the used water tank (see chapter on maintenance).

The used water tank can also be drained automatically by connecting a drain tube to the D4 fitting located at the back of the sterilizer (see § 4.6).

5.3DATE-CLOCK SETTING

5.4FILLING THE CLEAN WATER TANK

5.4.1Manual filling

Use only high quality distilled or demineralized water (see Appendix 7).

Slide the tank cover to the right to access the clean water tank inlet.

Remove the cap (1) from the tank inlet.

Insert the funnel and fill the clean water tank with app. 3.5 litres of distilled or demineralized water. Once the clean water tank is almost full, an audible tone will sound; stop filling.

Place the cap (1) to close the tank.

Slide the tank cover back into its original position. Drain the used water tank (see § 5.5).

The water level in the clean water tank decreases during every sterilization cycle, while the water level in the used water tank is rising. The sterilizer is equipped with an internal water conductivity sensor that constantly monitors the water quality in regards to mineral content. Should the mineral content go beyond a maximum threshold (conductivity >15µS/cm), a warning message is displayed on the screen.

Every time you fill the clean water tank, drain the used water tank (see § 5.5).

5.4.2Automated water supply (optional)

If an automated water supply system is connected to the sterilizer (see § 4.5), the clean water tank automatically fills

once the water level drops below the minimum level.

An internal water conductivity sensor constantly monitors the water quality in regards to mineral content. Should the mineral content go beyond a maximum threshold (>15µS/cm conductivity as defined by the European Norm EN 13060), a warning message is displayed on the screen (see screenshot to the left).

Water of low quality with high mineral contents can impair the sterilization process and seriously damage the internal components of the sterilizer. Damages caused by water of poor quality will not be covered by the manufacturer’s warranty. Once the non conform water message is displayed, check the water source (refer to the water supply system user manual; replace resin cartridges etc.). In case distilled or demineralized water is purchased, switch to a brand of better quality.

5.5DRAINING THE USED WATER TANK

When the waste water in the used water tank reaches the maximum level, the following message is displayed:

The message will disappear once the used water tank got drained. Keep draining the tank until it is completely empty.

5.5.1Manual draining

Open the service door at the front of the sterilizer.

Insert the drain tube into the quick connector for the used water (grey connector / right).

Drain the used water tank until it is completely empty. Press the push-button on top of the quick connector to dislodge the drain tube.

Never reuse water from the used water tank!

5.5.2Continuous draining

If the permanent drain tube for automated draining of the used water is mounted, the used water tank gets drained automatically. For more information see § 4.6.

If the sterilizer is not used for more than 3 days, both water tanks should be completely drained in order to avoid algae growth or any other deposits.

5.6MEMORY CARD

5.6.1Inserting / removing the memory card

Lisa 517/522 sterilizers are equipped with a digital cycle data recording system. Cycle data are written and saved on removable/rewritable memory cards.

- Insert the memory card into the dedicated slot behind the service door until it clicks into its final position. Ensure that the flat corner of the card points to the top/right (see image to the right).

- Periodically remove the memory card to download cycle data to a computer.

- To remove the memory card, slighty push it in and pull it out gently. For further instructions on the use of the memory card, see §12.
