Quantity and quality of the coolant
The coolant level is important for the correct operation of the machine. It must always be between the minimum and maximum level indicated on the
trolley. Top up with demineralized water if necessary.
Replace the coolant every 2 years :
1
Switch off the power supply using the switch located at the rear of the machine (OFF position) and disconnect the unit from the mains.
2 Place a bucket (min. 30 l capacity) under the machine drain hole.
3
Unscrew the drain plug located under the
machine using a 10 mm torx spanner.
(Ref. S6262)
4 Rinse the inside of the tank with running water to remove deposits.
5 Replace the drain plug. (
