Note for technicians:
Service maintenance 2 coincides with descaling of the steam boiler. During the descaling of the steam boiler, the water filter sieve must be removed from the
water filter (risk of blockage due to suspended particles). The new water filter sieve must only be used AFTER descaling (otherwise there is a risk that descaler resi-
dues may get into the water filter).
Service maintenance 2 coincides at the same time as the boiler pressure test.
