(*) Unless otherwise required by applicable laws.
The frequency of the operations described in the table above should be considered
indicative.
In fact, it may undergo variations according to the method of use of the machine and the
system in which the latter is required to operate.
7.4 WATER FLOW CONTROL AND EXTERNAL CLEANING OF
EXCHANGERS
The variation of the flow rate in the exchangers can be caused not only by the presence of
impurities in the filters, the wear of the pumps or incorrect control of the same, but also by the
presence of scale inside the exchangers.
7.5 CLEANING AND / OR REPLACING THE AIR FILTERS
Air filter access: In all models (F1, F2), the air filters are removed from the front access.
7.6 EXTRAORDINARY MAINTENANCE
In case of need of repairs, contact a Service Centre/Distributor-Branch authorized by the
manufacturer.
INFORMATION
Failure to comply with the above will make the warranty null and
void and relieve the manufacturer of all safety related
responsibilities.
OBLIGATION
Only use original spare parts (see the list of “Spare Parts
cathalogue”).
8 DISPOSAL OF THE MACHINE
When dismantling the machine, contact a Service Centre/Distributor-branch authorised by the
manufacturer to arrange for its disposal.
When components are replaced, or when the entire machine is
removed from the installation at the end of its useful life, the
following requirements must be observed to minimise impact on the
environment:
•
if the hydraulic circuit contains anti-freeze solutions, such
content must be collected and delivered to the appropriate
collection centres.
• the structure, the electrical and electronic equipment and the
components must be sorted according to category and
material and delivered to the collection centres;

observe the domestic laws in force.
OBLIGATION
THE MACHINE CONTAINS ELECTRICAL AND ELECTRONIC
EQUIPMENT, WHICH MAY CONTAIN SUBSTANCES THAT ARE
HARMFUL FOR THE ENVIRONMENT AND HUMAN HEALTH, AND
THEREFORE CANNOT BE DISPOSED OF WITH NORMAL URBAN
WASTE.
The machine is identified with the following symbol
to indicate that it must be disposed of by separating the various materials.
The customer has an important role in ensuring reutilisation, recycling and other forms of
recovery of the machine.
The machine is classed as PROFESSIONAL by WEEE Directive 2012/19/EU. Upon
dismantling, it must be treated as waste by the user, who may ask the reseller to collect it,
or take it to authorised waste collection centres.
Italy only:
MEHITS is part of the RIDOMUS consortium for the disposal of WEEE waste at the end
of its life. At the end of the useful life, the owner of products classed as waste may
contact the distributor, so that they can be collected free of charge by the above
consortium.
