IATE In my experience, vedlikehold is mostly used in the sense to physically maintain something, which in this case would apply to the installation.
Sometimes it is useful to use IATE for translation of Norwegian terms, by changing the spelling to Danish (vedligeholde). Naturally, it is not entirely reliable, but is sometimes useful as a suggestion.

I actually need to translate it into Polish, but as no NO-PL dictionaries are available, I need to use English as the reference language here (more translators know the NO-EN combination as NO-PL). The word maintanenance in Polish means either to preserve or to support financially (this is why I ask what the phrase refers to).

Sounds like the agreement from your context, but wouldn't "maintenance" cover both eventualities?
