ACS GROUP Marathon Series Beside-the-Press Granulators 

4-2  Pneumatic Evacuation Systems Checklists 

Marathon Series beside-the-press series granulators can be supplied with an optional fan or 
blower system to provide efficient evacuation of granulate from the machine. ACS Group offers 
a large variety of fan configurations. The following checklist is intended to be representative of 
the basic functioning and design of a fan, rather than being specific to one particular 
configuration. 
 

 

Have all installation and preparation instructions been read and followed? 

 

Have sufficient location clearances been allowed? 

 

Has the equipment been grounded as required by local codes and/or Article 250 of the 
National Electric Code? 

 

Have all motors been checked for rotation? 

 

Have all machine controls and push buttons been checked for proper functioning? 

 

Have the drive belts been checked for alignment and tension? 

 

Are all accessory components electrically and mechanically connected with proper support 
and with all fasteners tight? 

 

Are optional separator and filter units empty? 

 

Are all electrical enclosure boxes tightly closed and clamped shut? 

 

Are all personnel clear of the fan? 

 

Have all auxiliary components been checked for any foreign matter? 

 

 

4-3  Granulator Operation 

The machine is ready for operation when all doors, covers, guards, and limit switches are in 
place, securely fastened, and functional and all accessory components are properly connected. 
 

1.

 

Turn the main disconnect switch to the 

ON

 position. 

2.

 

Start the granulator and fan (optional) by pressing the appropriate push button at the 
operator station. 

3.

 

Load feedstock at a uniform rate that does not exceed the capacity of the machine; see 
Figure 1 on Page 15. 

4.

 

For color and/or material changes, allow all existing material to clear the granulator and 
any downstream equipment before stopping the machine. Doing so reduces cleaning 
requirements.
