1.5 INTERVENTION AND MAINTENANCE
It is useful to remember that the manual can not substitute the suitable experience of the user; for some maintenance operations,
the manual represents a reminder of the main activities for competent operators, who have attended, for instance, instructive
courses promoted by the manufacturer.
Please, read carefully the following suggestions:
- a preventive and constant maintenance grants the high safety standard. Do not postpone the required reparations and make sure
they will be done by qualified staff and by using exclusively original spare parts;
- schedule carefully each intervention;
- operators workplace should be clean and free from objects which could limit their movements;
- operators should avoid inaccurate operations and positions, in order not to compromise their balance;
- operators should pay attention to risks of trapping or cloths/hair entangling in moving parts; the use of a cap is strongly
recommended for people with long hair;
- necklaces, bracelets and rings could be dangerous;
- the place should be suitably lit up; an inadequate lighting can be dangerous;
- wait approximately half an hour after the turning off of the machine, before intervene for any maintenance, in order to avoid
burns;
- do not repair high pressure damaged pipes with welding;
- during installation and maintenance, fluids in the refrigerant circuit and electric parts, can
generate dangerous situations;
- reduce, as much as possible, the opening time of the refrigerant circuit: this because, even for a short time, the air exposition of oil
causes the absorption of high humidity quantities and this leads to the creation of weak acids;
- each intervention on the unit should be made by qualified staff;
- before starting a maintenance intervention, make sure the power supply has been turned off;
- make sure the safety devices work correctly; if not, do not turn on the unit;
- use only equipment suggested by the manufacturer of the unit, in order to reduce the possibility of accidents due to low quality
equipment;
-after the cleaning of the unit, the operator should verify that there are not damaged parts; in case
he finds out something wrong, he should ask for the intervention of a maintenance technician;
- the place should always be clean and properly tidied up, because smearing of oil or grease could cause sliding or fallings;
- the use of inflammable fluids during cleaning operations is forbidden.
During the cleaning operations, do not use gas oil, oil or solvent because while the first leaves an oily patina, which leads to dust
attraction, the latter can damage the paint and leads to the creation of rust. If some water seeps into the electrical devices, it will
produce oxidation, which can cause the dysfunction of the unit. You should not use water or steam spout on sensors, connectors
and other electrical parts.
Please pay attention to the integrity of pipes and other devices, which could wear out. Check that there are not leaks of fluids and
other dangerous substances. If something like this occurs, the operator should not turn on the unit before the reparation.
