This figure indicates the areas on the machine where there may be a safety hazard during 

operations:

When the machine is operating, check the level of oil in the two tanks making 

sure that it does not overflow.

We remind you that maintenance and repair carried out by not qualified staff 

change the standard of security of the machine and expose the worker to serious 

risks.

NEVER

 disconnect the 

HP

 and 

LP

 hoses, unless expressly stated in this guide. 

Do not manually action the manual filling valves during normal operating phases 

unless expressly stated in the instructions.

Always wait some minutes after having switched off the machine to allow the 

system to be correctly reset (temperature and pressure).

In no case should the operator use combustible or flammable liquids or detergents 

for cleaning the machine. 
During maintenance work do not contaminate the environment with eventual 

residual  waste  products  and  always  follow  the  prescribed  directives  in  force 

regarding disposal.

NEVER

 disassemble the cylinder.

The machine is delivered with 

the cylinder correctly positioned 

in its seating on the weighing 

scale and already fixed with 

brackets (n. 2) for this purpose. 

3.  Warning

1)

  Area where refrigerant may be

     ejected.

2)

  Components carrying live current.
