7.2 General
Munters dehumidifiers are designed for long-term, continuous usage with a high degree of reliability.
As with all machinery, regular service and maintenance is required to keep the dehumidifier in optimal
condition so that it works most efficiently.
Service and maintenance interval lengths are primarily determined by operating conditions and the
environment in which the unit is installed. For example, if the process air contains a lot of dust, preventative
maintenance should be carried out at shorter intervals. The same also applies if the unit works intensively.
7.3 Service options
In addition to commissioning of the unit there are four service options (A - D) as standard.
S
. Commissioning/start-up.
A
. Inspection and if necessary change of filter. General function check.
B
. In addition to A, safety check and capacity, temperature and humidity regulation measurements.
C
. In addition to B, preventive replacement of some components after 3 years of operation.
D
. In addition to C, preventive replacement of some components after 6 years of operation.
NOTE!
Always contact Munters for service or repair. Operating faults can occur if the unit is maintained
insufficiently or incorrectly.
NOTE!
Commissioning/Start-up inspection "S" by Munters is mandatory to validate the full warranty.
