READ THIS MANUAL ATTENTIVELY  

BEFORE INSTALLING OR USING THE APPLIANCE  

 

 

These symbols inform you about dangers and the measures to be taken to avoid them.   

 

The comments in bold type emphasise the key points to observe to ensure you use your drier correctly.

Introduction 

1.1

 

Principle  

Your Mastéria drier dries air by refrigeration. Hot, wet compressed air entering the Mastéria drier is cooled by 
an exchanger down to the programmed dew point temperature. The steam which condenses in liquid form 
during cooling is separated mechanically and is then purged by an electronic system with a time-out.  
The compressed air leaving the appliance is dry.  

1.2

 

Originality  

Your Mastéria drier has several unique features compared with the other products on the market:   

 

Reduced consumption due to an air-to-air heat exchanger in all models in the range above the MPE010. 
The dry, cold air from the drier is used to pre-cool the hot, wet air inlet.   

 

Mechanical separation guaranteed in all operating modes by a condensate separator developed from 10 
years experience.   

 

High quality, anti-corrosion construction that is easy to maintain and very strong.   

 

Electronic regulation with a user-friendly, clear, digital display panel.  

Finally, and especially,   

 

DTM

®

 technology, providing a host of additional benefits  

 

Robustness: DTM

®

 technology

  

eliminates fragile, pressure-operated valves  

 

Economy: DTM

®

 technology

 

only uses minimum power  

 

Safety: DTM

®  

technology guarantees the total integrity of the compressed air circuit from any risk of 

contamination by the cooling agent.  This ensures that air quality meets the highest standards.  

 

Performance: DTM

®

  technology guarantees you get exactly the dew point you set.  

1.3

 

Standards  

The air delivered by Mastéria dryers complies with ISO standards 85 731 and 7183.  

Mastéria range dryers comply with the following European directives:   

 

89/336:  " Electromagnetic Compatibility "   

 

89/392/EEC:  " Machine Safety "   

 

73/23/EEC:  " Low Voltage" 

 

97/23/EEC : "Pressure Equipment"
