To  make  the  reading  of  this  manual  easier,  we  have 
prepared the list of the most important technical terms used 

Cycle: Sequence of steps. 
 
Recovery:  Extraction  of  refrigerant  from 
the vehicle. 
 
Recycling: 

Cleaning 

of 

refrigerant, 

includes:  separating  out  oils,  removal  of 
non-condensable 

gas 

and 

single/multiple  pass  through  filters  to 
reduce  humidity,  acidity  and  particulate 
content of the fluid. 
 
Disposal:  disposal  of  refrigerant  for 
storage 

followed 

by 

destruction/scrapping  by  an  authorised 
waste management centre. 
 
Vacuum  cycle:  Draining  out  of  a  motor 
vehicle A/C system and separation out of 
condensed  matter  and  humidity,  using 
only the vacuum pump. 
 
Oil  charge:  Charge  of  oil  into  an  A/C 
system  to  ensure  the  correct  charge  as 
specified by the vehicle's manufacturer. 
 
Charge:  filling of refrigerant into the A/C 
system  in  the  amount  specified  by  the 
manufacturer. 
 
System flushing: Cleaning phase for the 
removal of possible polluting substances 
from the A/C system or parts of it. 
 
Non  condensable  gas:  Refrigerant 
stored  in  gaseous  phase,  including  air 
and nitrogen. 
 

3.4 

Guidelines for the handling of refrigerant

 

3.4.1 

Precautions for refrigerant storage

 

The refrigerant removed from the A/C system must be handled with 
care to prevent or minimise the risk of mixing with other refrigerants.
This  machine  is  suitable  for  treating  R134a  or  R1234yf 
refrigerants, individually (not simultaneously).
The external cylinders used to store the refrigerants must be clearly 
marked to prevent mixing different refrigerants.
Cylinders  shall  be  free  from  oil  or  other  contaminants  and  clearly 
marked so as to identify the refrigerant contained.
 

 

ATTENTION: when handling, using and storing 
R-1234yf  refrigerant  and  dealing  with  emergency 
situations,  MAKE  SURE  to  refer  to  the  product’s  safety 
sheet. 

GET  THE  SAFETY  SHEET  FROM  YOUR  REFRIGERANT 
SUPPLIER AND FOLLOW ITS INSTRUCTIONS.
REFRIGERANT  R1234YF  IS  DEFINED  AS  FLAMMABLE
