Fig. 6-57 Filling the water bag
ATTENTION
• Do not use water that has been distilled more than once!
• After the water bag has been lled, there should be as few bubbles as possible
in the connection tube. Press the closing valve inwards to let the air escape (see
picture below) until the hose is fully lled with water.
Fig. 6-58 Venting the connection tube
• Place the F-SW handpiece into the F-SW handpiece holder so that any air bubbles
that form will be immediately sucked up by the bubble trap.
• Activate “Fill water circuit” operating mode in the “Setup” menu
• Connect the water bag to the water tube connection on the rear of the instrument
as soon as the message appears.
