If there is a considerable quantity of lime formation,
use a specific descaling product for lime elimina-
tion, or a mixture of vinegar and water, procee-
ding as follows:
- wait till the machine has cooled down comple-
tely.
- open the discharge cock B to empty the boiler.
- pour a mixture of water and vinegar, or a specific
descaling product into the water reserve tank.
- fill the boiler.
- when specific descaling products are used, leave
the product to act for at least 3 hours.
When using vinegar and water, leave it for 12 hours.
Once sufficient time has passed for the products to
remove the lime, proceed as follows:
- power on the machine and then switch it off
when the gauge shows a pressure reading of 0.5
- 1 bar; this will create an internal pressure in the
boiler, sufficient to allow water and limescale to
be removed.
- open the discharge cock B to allow the contents
of the boiler to be removed.
If there is still a certain quantity of lime present repe-
at the operation until the discharged water is free
of lime deposits.
N.B: during the boiler cleaning operation, avoid
letting out steam from the pistol.
- Once the operation has been completed, close
the cock B carefully.
- Adequate and suitable maintenance operations
are a deciding factor for long machine life, correct
working conditions, top performance, and to en-
sure that all the safety systems provided by the
manufacturer function correctly.
- Maintenance, repairs and replacement opera-
tions must be performed by qualified technicians
familiar with the machine technology.
