9.1 - General recommendations
WARNING !!! The user cannot change the internal
wiring of the unit.
WARNING !!! Service and maintenance must be
performed by qualified technician. If the appliance does
not work, immediately disconnect the power supply.
WARNING !!! The control system is able to
automatically analyze the various protection problems
during daily use, and show the error code on the
display. The appliance can reset itself. During normal
operation, the pipes inside the appliance do not need
any maintenance.
WARNING !!! Under normal environmental working
conditions, the user only has to worry about cleaning
the surface of the external evapo-condensing battery.
Operation to be performed every 4-6 months.
WARNING !!! If the work environment is particularly
dirty or oily, the external part of the evapo-condensing
battery must be cleaned with specific professional
detergents to ensure optimal performance and efficiency.
WARNING !!! Please pay attention to the
surrounding environment to ensure that the unit is
installed safely and that the air intake and exhaust are
not obstructed.
WARNING !!! In the event that the appliance is not
used for a long time in winter, it is recommended to drain
the system to avoid damage due to freezing.
9.2 - Cleaning the water filter
The water filter must be cleaned in accordance with its relevant
manual to ensure the correct flow rate of the system. It is
recommended to clean it after the first month and every 6
months thereafter.
9.3 - Cleaning the plate heat exchanger
Thanks to the great turbulence inside the heat exchanger
we have a self-cleaning effect. However, in certain cases the
tendency to get dirty is very high. For example if you use very
hard water at high temperatures. In these cases it is possible
to clean the heat exchanger by circulating cleaning liquids.
Use a tank with weak acid such as 5% phosphoric acid (if
cleaning is done frequently use oxalic acid). Pump the liquid
through the heat exchanger. This operation must be carried
out by qualified technician, contact the assistance center.
