Start-up 

 

DANGER!

 

This FG metal-edge filter is not allowed to be put into 
operation until it has been established that the 
machine/system in which it is to be installed complies 
with the requirements of the applicable EC directives, 
harmonised standards, European standards or equivalent 
national standards. 

 

 

DANGER!

 

 

Explosion hazard! 

  Risk of injury to persons or damage to 

property. 

  The FG metal-edge filter must be 

completely vented prior to start-up for 
use with all media which are capable of 
forming explosive gases. 

  The FG metal-edge filter must be 

completely filled with liquid. 

  Take steps to prevent air pockets. 

 

 

DANGER!

 

Danger due to high pressure in the filter! 

  Risk of injury to persons or damage to property 

  Do not allow concentrate to spatter into the 

atmosphere.  

 

  Check that all the caps have been removed from the 

connections. 

  Remove all foreign particles from the filter. 

  Check the pipe unions. 

  Tighten the bolts. 

  Rinse the pipes. 

 

10.1  Functional test 

Direction of rotation of the gear motor  

  Unscrew the cap of the gear motor. 

  Start up the gear motor briefly (<1 s). 

  Compare the direction of rotation of the shaft with that 

shown by the arrow (clockwise direction). 

  Reverse the terminal connections of the gear motor if 

necessary. 

  Screw the cap of the gear motor back on again. 

 

 

 

 

 

Fig. 13:  Direction of rotation of the gear motor 

To check the differential gauge/switch (optional) 

 

Refer to the enclosed manufacturer’s documentation.

 

 

Check the function of the drain valve (optional) 

  Supply compressed air to the pilot valve. 

  Actuate the manual release for the pilot valve. 

  The drain valve opens. 

  Set the manual release to the OFF position. 

 

The drain valve closes. 

 

10.2  Programming the operating settings 

  Switch on the control. 

  Carefully open the feed valve. 

  Vent the filter. 

  Note the initial differential pressure (optional). 

 
Settings for time-controlled cleaning 

  Set the times according to the operating conditions and 

correct them if necessary. 

 

Settings for differential pressure-controlled cleaning 
with a differential gauge/switch 

 

Refer to the manufacturer’s documentation. 

  Adjust the set differential pressure to the setpoint  

(see contract documentation). 

 

Initial differential pressure 

The initial differential pressure varies according to the 
application. 
General guide:  
Installation on discharge side: delta p
