START UP 
 

DANGER

:  

TO AVOID THE  RISK  OF  BURNS,  IT IS ESSENTIAL  BEFORE  START-UP,  VERIFY THAT IS 

NOT POSSIBLE TO ACCESS THE REAR PART OF THE MOUNTING PLATE. IF INSTALLED AS SPECIFIED 

IN THIS MANUAL, THERE IS NO RISK FOR ACCIDENTAL CONTACT WITH HOT PARTS. FOLLOW THIS 

PROCEDURE FOR SAFE OPERATION: 

 

•

 

Open the cooling water inlet and outlet valves (if installed), for non self-cooling systems and 
ensure that a full flow can be seen at the cooling water outlet.  

•

 

Gradually open the sample inlet valve (not included in the system) and regulate the flow to 
achieve a value between 100 to 250 cm³/min. Then is necessary to wait the time required for 
the sample to go out from sample outlet.
