For units installed in an aggressive atmosphere with a high rate of fouling, cleaning of the coil should be part of the routine
maintenance programme. On this type of installation, all dust and particles deposited on the batteries must be removed as
soon as possible by periodic cleaning in accordance with the above instructions.
9.2 CLEANING OF EXTERNAL SURFACES
The sheets of the outer casing must be properly cleaned to avoid the accumulation of dust / dirt, preventing the onset of corrosion. The painting
ensures resistance to atmospheric agents but it is good practice to make sure to remove any dirt present, cleaning the surfaces with neutral
detergent and water, especially if the unit is installed in places with an aggressive atmosphere (high level of pollution, salt , etc).
9.3 EXTRAORDINARY MAINTENCE
All extraordinary maintenance jobs must be carried out by an authorised assistance centre.
Some extraordinary maintenance works may involve the replacement of broken components, which may have significant mass. Below is the list
of components (standard and optional) and the approximate weight for each piece (take into consideration that any residues of oil, liquid gas,
water can increase the weight). Consult the table before the maintenance phase (or refer to the label of the component itself) and choose the
equipment / posture most suitable for the work to be carried out taking into account the load limits imposed by the technical standards and the
state of health and ability of the worker himself.

10. DECOMMISSIONING
Once the unit has reached the end of its life cycle and needs to be replaced, the following operations are recommended:
• the refrigerant has to be recovered by trained personnel and sent to proper collection centres; according to the procedures indicated in
Regulation No. 517/2014 on fluorinated greenhouse gases;
• any antifreeze additives in the water circuit must be recovered and disposed of properly;;
• the compressors’ lubricating oil has to be collected and sent to proper collection centres;
• the structure and the different components, if unusable, must be scrapped and divided according to their nature; there is especially a good
amount of copper and aluminium in the machine.
These operations allow easy material recovery and the recycling process, thus reducing the environmental impact in accordance with the pro-
visions of Directive 2012/19 / EU on waste electrical and electronic equipment (RAEE).
The user is responsible for the proper disposal of this product, according to national regulations in the country of destination of the appliance.
For more information you should contact the Installation Company or local competent authority.
An incorrect decommissioning of the appliance may create serious environmental damage and endanger people’s safety.
Therefore, it is recommended that the unit be disposed only by authorised persons with technical training who have attend-
ed training courses acknowledged by the competent authorities.
It is required to follow the same precautions described in the previous paragraphs..
Pay special attention during disposal of the refrigerant gas.
The illegal disposal of the product by the end user leads to the application of the penalties in accordance with the law in the
country where the disposal takes place.
The crossed-out bin symbol applied on the appliance indicates that the product, at the end of its useful life, must be collect-
ed separately from other solid/municipal waste.
The units are manufactured in accordance with the EC directive on waste of electric/electronic equipment and the harmful
effects of incorrect disposal are provided in the user/installer manual. The manufacturing company or its importer/retailer is
available to respond to any requests for additional information.
11. RESIDUAL RISK
The residual risks related to handling, installation and normal operation of the unit are shown below. Any failure by the user and installer to com-
ply with the instructions / indications given in the manual (for which the references are given in the table) entails the persistence of these risks,
which cannot be eliminated by the manufacturer, who has already adopted all the necessary design measures because each risk is minimized.
