OTHER PROHIBITIONS AND USE
LIMITATIONS: Only use pure R134a or
R1234yf refrigerants, refrain from using
on vehicles containing other types of
refrigerants or mixtures of the two
refrigerants or other refrigerants.
Mixture with other types of refrigerant
produces serious damage to the
conditioning and cooling systems. Mixed
refrigerants have to be disposed of
according to the current regulations.
Never use ACX equipment with systems
containing compressed air; mixtures of
R134a or R1234yf with air or oxygen may
be potentially flammable.
Do not modify calibration of safety
devices. Do not remove seals of safety
valves and of control systems. Do not use
external tanks or other storage containers
that are not type-approved or without
safety valves.
Make sure the equipment's aeration and
ventilation ports are not obstructed or
covered while the equipment is operating.
HOSE CONNECTIONS: Hoses may
contain pressurized refrigerant. Before
changing the service couplers, check the
respective pressures in the hoses
(pressure gauge). Before connection to a
car A/C system, to an external
tank/cylinder, check that the quick
couplers are closed (unscrewed HP and
LP valves). Scrupulously follow the
instructions on the equipment's display.

equipment in a safe place, disconnected
from the mains, away from excessive
temperatures, humidity and the risk of
