Oilon and Lämpöässä heat pumps are highly reliable and easy to maintain. If the

there is usually no need for maintenance.
It is recommended to check the following at least once a year:

monthly in the first year.

Annual inspection
According to rules and regulations by authorities, appliances with a refrigerant charge
greater than 6 kg must undergo annual leakage testing. Heat pumps with a 3–6 kg
refrigerant charge are hermetically sealed, and do not require annual inspection.
A periodic inspection service is available for our heat pumps. During each inspection,
the heat pump’s operation is checked step by step. Any observations will be recorded
in an inspection report and the necessary corrective measures (such as adjustments to
settings) will be taken. For more information about the service, contact your dealer.
