2.5 Maintenance

The ongoing maintenance of this unit can be carried out either by the person

normally in charge of maintaining the building or through a contract with a well-

reputed service company.

2.6 Handling of refrigerant

The following information summarises the requirements and guidelines for hand-

ling the refrigerant used in cooling units. For further information, see the F-gas

Regulation (EU/517/2014 on fluorinated greenhouse gases) and the Swedish

Refrigerant Regulation (SFS 2016:1128). The purpose of the regulations is to

contribute to achieving EU goals for reduced climate impact in accordance with

the Kyoto Protocol.

Operator responsibilities

Generally speaking, the unit operator must:

• Minimise and prevent leakage

• Take corrective action to remedy any leakage that arises

• Ensure that the service and repair of the refrigerant circuit is carried out by a

certified refrigeration technician

• Ensure that refrigerant is handled in an environmentally secure manner and

in accordance with national regulations.

By operator, we refer to the European Parliament’s definition: “...the natural

or legal person exercising actual power over the technical functioning of the

equipment and systems...”.

Leakage inspection and registration

The following applies to one-piece units with 5 CO₂ e(tonnes) refrigerant content

or more per circuit – Envistar Compact with StarCooler (code ACEC, size 16):

• Leakage inspectionmust be carried out by a certified refrigeration techni-

cian:

- When installing/commissioning the unit

- Periodically at least once per 12 months, i.e. no more than 12 months

between inspections

- Within one month after any work is performed (for example sealing a leak,

replacing a component).

• The operator must record events, such as the volume and type of refrigerant

topped up, refrigerant taken into possession, results of inspections and work

done, person and company who carried out service and maintenance.

For size 04-10, no periodic leak detection or record keeping is needed, but the

requirement for leak inspection during installation does apply.
