11. HOW TO USE SOFTBALLS (CERTAIN MODELS
ONLY)
Softballs (C7) are an innovative treatment system that prolongs
the life of the machine, without altering the properties of the
water, while ensuring consistently creamy and aromatic coffee.
To optimize the effectiveness of the treatment, leave Softballs in
the water overnight before use.
1. Take the sachet of Softballs from the wrapper (fig. 31).
2. Rinse the sachet of Softballs under running water (fig. 32).
3. Immerse the sachet in the water tank (A7) (fig. 33).
4. Change the sachet of Softballs every 3 months (fig. 34).
12. DESCALING
Important!
• Before using the descaler, (C6)read the instructions and the
labelling on the pack.
• Use De'Longhi descaler only. Using unsuitable descaler
and/or performing descaling incorrectly may result in
faults not covered by the manufacturer's guarantee.
• Descaler can cause damage to delicate surfaces. If the prod-
uct is accidentally spilt, dry immediately.
