  AKT – Operating instruction for refrigerant drier     

 

AKT-4 

Appendix KT refrigerant drier (cont.) 

 

Before completing any maintenance work, please follow all 
safety provisions for electrical systems and electrical de-
vices (see Chapter 1 of the original operating manual). 

 
 
The compressed air refrigerant drier must be mainained at dif-
ferent intervals. The maintenance intervals heavily depend on 
the utilisation type and the conditions oft he installation site. The 
following maintenance work must be completed daily: 
 

1.  Check the function of the steam trap; check if water is 

drained; valve test (manual drain condensation): 
 

2.  Check the pressure dew point display; for deviations 

from the normal range, see chapter 5.2.2 and 5.2.3 in 
the original operating manual 

 

3.  Check the compressor for contamination 

 

 

Specific notes about other maintenance intervals and work 
can be found in the manufacturer original operating manual 
under Point 5 Maintenance.
