6 Maintenance
6.1 Regular check and maintenance
Be careful not to spill liquid refrigerant when refilling the evaporator or
flushing the refrigerant from the evaporator with water. The refrigerant
can cause frostbite.
Installation, commissioning, or service of the appliance is to be carried
out by an authorized service provider, adhering to all local regulations
and requirements.
Do not touch any liquid without protection. Contact with operating liquids
may cause frostbite. Always immediately inform operating staff about
leaks.
Before performing any work on components with hot surfaces, make
sure that the component has cooled down.
The removable front panels of the heat pump are heavy and bulky. Use
caution when detaching and lifting the panels.
Heat pumps check and maintenance must comply with the European Union's
Regulation No 517/2014 and follow the attached table. CO2 equivalent of refrigerant
can be calculated by multiplying the refrigerant charge by the refrigerant GWP value.

When performing annual maintenance, perform the checks and tasks indicated in the
maintenance checklist (
Maintenance report
) supplied with the heat pump.
Each time annual maintenance is performed, the service provider must fill out a form in

the next required annual maintenance should be placed. Apply the sticker in a visible
location on the heat pump.
