5. MAINTENANCE
5.1. Maintenance and care
The Lämpöässä ground source heat pump is an easy-care and reliable
heating system that does not require regular maintenance. If the installa
-
tion is carried out with care and in accordance with the instructions pro
-
vided, there is usually no need for maintenance. The fill container and
mixture circuit filter should be checked every couple of weeks during the
first few months and afterwards approximately once a month for the first
year of use thereafter.
Lämpöässä heat pumps which includes 3-6 kg refrigerant are hermatically
sealed and therefore annual inspection is not required. You are offered the
possibility of concluding an agreement on periodic inspections, in connec
-
tion with which the operation of the Lämpöässä heat pump is covered
stage by stage. The observations are registered in the inspection record
and necessary measures taken (such as adjustments, for example). For
additional information on the periodic inspection agreement, visit huolto@
lampoassa.fi.
