6.2 Regularserviceandmaintenance
Munters dehumidifi
ers are designed to r un reliably in continuous operation for long periods. Regular
service and mainte
nance is required to ensure that the dehumidifier is operating as efficient and economical
as possible.
Service and maintenance interval lengths are primarily determ ined by operating conditions and the
environment in which the unit is installed. For example, if the process air contains a lot of dust, preve ntative
maintenance should be carried out at shor ter intervals. The same also applies if the dehumidifier works
intensively.
The service levels for a standard service and maintenance progr amme are described in s e ction
6.3, Service options.
Thedehumidifier's control system is equipped with a service indicator. During installation and
commissioning, an estimate should be made of a suitable number of operating hours until the next ser vice,
or the date for the next service. This value is prog rammed by Munters personnel at initial start -up of the unit.
