17. MAINTENANCE
ATTENTION! Before any inspection, maintenance, or
anything else involving access to the internal parts of the
appliance, disconnect the general power supply.
17.1 Cleaning the exchangers
The cleaning of the finned air / refrigerant gas exchanger must be
performed at least twice a year, at the beginning of the operating
season and whenever it is necessary for particular installation
conditions. Keeping the exchanger clean involves constant
performance over time, with a reduction in management costs.
To carry out the cleaning operations, use a vacuum cleaner or
a brush with soft spatulas, avoiding damaging the fins of the
exchanger. If possible, use a light jet of compressed air to pass
carefully through the spaces of the fins.
17.2 Annual inspection
To keep the system efficient, it is advisable to have the following
checks carried out by an Authorized Technical Assistance
Center:
- control of refrigerant charge and operating parameters;
- check supply voltage and electrical absorption;
- functionality of the control and safety devices;
- cleaning the water filter and exchangers;
- control of the hydraulic system, of the presence of air in the
piping and possible filling integration;
- checking and tightening the electrical connections and
hydraulic;
- verification of the casing, with particular attention to triggers
of corrosion. For appliances installed nearby of the sea
requires periodic inspection from carried out at least once a
year.
