CAUTION: Do not clean the coil using high-pressure cleaners so as not to apply excessive pressure which could cause irrepa
-
rable damage. Damage caused by cleaning with unsuitable chemical substances or excessively high water pressure will not
be recognised under warranty.
CAUTION: The aluminium fins are thin and sharp. Pay the utmost attention and use appropriate PPE to avoid cuts and abra
-
sions. Cover your eyes and face appropriately to avoid squirting water and filth while blowing. Wear waterproof shoes or
boots and clothing covering your entire body.
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 MAINTENANCE
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;
•
electronic components such as regulators, driver boards and inverters should be dismantled and sent to 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 provi-
sions 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.
