14 Maintenance and service

NOTICE

Maintenance MUST be done by an authorised installer or service agent.

We recommend performing maintenance at least once a year. However, applicable
legislation might require shorter maintenance intervals.

NOTICE

Applicable legislation on

fluorinated greenhouse gases

requires that the refrigerant

charge of the unit is indicated both in weight and CO

equivalent.

Formula to calculate the quantity in CO

equivalent tonnes:

GWP value of the

refrigerant × total refrigerant charge [in kg] / 1000
