12 - RESIDUAL RISKS

 

isolator on the attachment line of the unit itself, padlock it and 
display the appropriate warning sign. 

 
12.8 

Refrigerant 

 

The intervention of the safety valve and the consequent 
expulsion of the gas refrigerant may cause injuries and 
intoxication. Always wear suitable clothing including protective 
gloves and eyeglasses for operations inside the danger zone. 
Should the gas refrigerant leak please refer to the refrigerant  
"Safety sheet".  
Contact between open flames or heat sources with the 
refrigerant or the heating of the gas circuit under pressure (e.g. 
during welding operations) may cause explosions or fires.  
Do not place any heat source inside the danger zone. 
The maintenance or repair interventions which include welding 
must be carried out with the system off. 
 

12.9 

Hydraulic parts

 

Defects in tubing, the attachments or the cut-off parts may cause 
a leak or water projection with the consequent damages to 
peopl, things or shortcircuit the unit.
