1.1.1  Safety  

 

 

This manual uses certain terms that are important for your safety.    
 

Warning  

Used to denote a danger that may result in injury.  

 

Attention 

Used to denote a situation that may result in damage to components of the system. 

 

 
1.2

 

  Location of the table  

 

 

 

 

To ensure optimal operation of the system, it must be installed on a surface that satisfies certain 

requirements.  
 

 

The surface must be even.

 

 

 

 

It is important that an appropriate location for the system is chosen. The system must be installed 

in  the  vicinity  of  bearing  walls  or  columns,  where  the  impact  of  low-frequency  oscillation  is  smaller. 
Furthermore, it is advisable to avoid placing the system in the vicinity of other sources of vibration such 
as elevators, ventilation systems, industrial equipment, and airflows.   
 

Warning  
 

 

The system is a metal-made current conductor. If used together with electrical devices, the 

table must be earthed.    

 
 
 

1.3

 

  Air supply requirements  

 

 

 

The operation of the system requires a constant supply of air. After the system has been filled in 

and set, air is used only for the operation of level controls when the load on the table changes. 
 

 

Compressed air tanks (receivers) may be used for keeping the system operative.    

 

 

The air supply should be clean and dry for the best long-term results. The filtering degree must be at least 

10 µm. 

The  filter  prevents  impurities  and  water  from  entering  the  level  controls,  thus  preventing  them 

from clogging.

 

 

 

The  working  pressure  of  the  system  is 

 The  required  minimum  working 

pressure for the support with the maximum load may be computed using the following formula:  

 

 

Where: 

P

 

means the required pressure

 

in atm (bar). 

Q

 

means the load on the support with the maximum load including weight of the table top (kg). 

  
Example: 

Q

 = 100 kg
