Tetrafluoroethane
A/C system: air conditioning system.
Equipment:
ACX 150/250
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.
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.

Guidelines for the
handling of refrigerant
4.4.1
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-134a or 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
REFRIGERANT.
