7.5 Unscheduled maintenance

After correctly starting-up and carrying out the relevant checks, the units normally do not need any intervention by the

customer service in order to check the charge of the refrigerant gas.

7.5.1 Special work

Over time, small leaks allowing the refrigerant gas to escape could be generated, so partially draining the circuit and

causing malfunctioning of the unit.

In these cases, the points from which the refrigerant gas is escaping must be found. These must be repaired and the

chargemustberestored,workingincompliancewithcurrentrulesandregulationsregardingequipmentcontaining

uorinatedgreenhousegases.

7.5.2 Exceptional work

Withuseoftheunit,particularsituationsmayoccurthatrequireworktobecarriedoutpromptly.

Even in an emergency, work on the unit must be carried out by skilled personnel in safe conditions.

The presence of oil on the unit, on the pipes or on parts of the unit can be a sign of gas leaks.

Repair the leakage point and restore the charge of refrigerant gas.

In the case of small oil leaks, clean the dirty parts with absorbent cloths, otherwise recover the leaked oil with absorbent

sheets. In any case, the material used must be disposed of in accordance with current rules and regulations.

Check whether it is necessary to restore the oil charge.
