"User Manual recommends to change it every year.
I found that little bit too offen.
Some other major brand recommends 5 years or 1000 hours.
In general, the recommendation in the user manual are a bit off logic,
Timing belt -> no change period, just check.
When breaks, no warnings and major damages.
Impeller -> change every year.
When breaks then over heats and warning by lower rpm limit, sound and light.
Maybe a mishap here."
