2.8 BEFORE FIRST START PROCEDURES 
🢥  The following points must be observed before operating the air dryer: 
 
A) Review all safety precautions. 
 
B)  The dryer connection piping measurements must be selected correctly.  
 
C)  The dryer connection piping must be adapted to the operating pressure.  
 
D) Never operate the dryer at a pressure above the maximum specified 
on the dryer label. 
 
E)  The drains should be opened to the atmosphere. If the drains are connected 
to a pipe / hose, the diameter of the hose / pipe should be large enough to 
create no back pressure during drain. It is not recommended to reduce the 
diameter of the hose / pipe less than the port that is given at the drain outlet 
of the unit. 
The hose / pipe should be at atmospheric pressure at all times. Back 
pressure in relevant pipes will result in permanent damage to the drain 
system and the affect function of the filters and / or dryers.
