Intended use of the dryer 

The dryer is exclusively intended for drying compressed air. Depending on 
defined input conditions, it dries compressed air for industrial use.  
The dryer is designed for compressed air, which is free from aggressive water, 
oil, and solid matter constituents. 

 

 

 

 

 

Note: 

Never operate the dryer without upstream filter. For this reason, the 
operator must install an appropriate upstream filter (degree of 
filtration < 0.01 µm, residual oil contents < 0.001 mg/m³). 
We recommend that you install an additional downstream filter to 
protect the downstream compressed air network against desiccant 
residues. 
Suitable filter solutions can be obtained from the manufacturer. 

 

 

 

As standard, the dryer is intended to be sited within a building and protected 
against the weather. When it is sited in the open air (option), the instructions on 
page22 must be complied with.  
The dryer may be operated only in accordance with the data on the type plate 
and in accordance with the contractual conditions.   

Suspected misuse

 

The dryer must not be misused as a climbing aid! Pipes, valves, and similar 
fittings have not been designed for such loads. They could fracture, tear off, or 
become damaged in another way. 

 

General safety notes 

 

 

 

 

 

For your own safety, when carrying out any work on the dryer comply with 
all applicable national safety regulations!  

 

 

 

Personnel qualification 

Only authorized and qualified specialist personnel may be tasked with the work 
on the dryer described in these operating instructions. The electropneumatic 
switch cabinet in particular must be opened and serviced by an instructed trained 
electrician only.  

Conversions and modifications

 

Without prior approval by the manufacturer, no conversions and modifications 
must be made to the dryer! Any non-approved modifications may restrict the 
operational safety of the dryer and cause damage to property or personal injury.
