Glossary
To make the reading of this manual easier, we have
prepared the list of the most important technical terms used
in the manual.
Refrigerant: Refrigerant fluid used in
advanced motor vehicle A/C systems.
The following refrigerant fluids
may be used:
•
R-1234yf CH2CFCF3 2,3,3,3-
Tetrafluoropropene.
•
R-134a C2H2F4 - 1,1,1,2-
Tetrafluoroethane
A/C system: air conditioning system.
Equipment: A/C service station for
recovering,
recycling,
draining
and
charging the A/C system.
External tank: Refrigerant bottle used to
fill the internal tank.
Internal cylinder: cylinder for refrigerant
storage.
Phase: Performance of a single function.

To make the reading of this manual easier, we have

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
