Regular maintenance
Cleaning of hydraulic system
End user can only carry out regular maintenance operations described in
following user guide, with the help of specialist if needed. The constructor
declines any liability if the procedures given are not being followed and
reserve it’s right to suspend the warranty.
Periodic cleaning is important to avoid bacteria growth. Especially when
the water supply is not covered by chlorine treatment, periodic
throughout cleaning is mandatory (at leat every 6 month)- or according to
water treatment systems installed before the dispenser.
Sanitization of hydraulic system must be carried out with a good oxidant
and solvent product, that efficiently removes silt and bacteria.
We suggest the use of hydrogen peroxide with a solution at 24 volumes,
and a maximum application time of 15 minutes. The use of other
disinfectant products, with strong oxidant power like peracetic acid or
ozone could lead to corrosions, vapors or noxious smell.
After the application of hydrogen peroxide, a good rinsing of hydraulic
circuits is necessary – at leat 5 liters for each circuit: ambient water, cold
water, sparkling water. The sparkling water systems, with its stock of
water, could need a longer rinsing. Litmus paper test can be used to check
if there is any hydrogen peroxide left..
Cooling system cleaning
The winglet of condenser for ventilation must be throughout cleaned by
aspiration or with a brush. Dust deposit will strongly reduce the
effectiveness of cooling system and irreparably damages the compressor
in the long term.
Warning any regular maintenance that need the intervention of
qualified professionals must be reported and described in the form at
the end of this manual “form II”.
Regular maintenance described is to be evaluated for a normal use of
the dispenser. In case of burdensome work amount of the machine,
the maintenance needs to be carried out more frequently
