MAHLE ACX380 Service Manual page 4

WORKPLACE: The station can work with both R134a and
R1234yf (the two refrigerants cannot be stored within the
station at the same time).
Refrigerant R1234yf is defined as flammable refrigerant.
Nonetheless, although refrigerant R134a is not defined as
flammable, mixtures of air or oxygen with R134a may
become flammable under very particular conditions.
The equipment must be operated outdoor or in a well-
ventilated location (at least 1 air change per hour). The
workshop has to be equipped with ventilation systems
able to ensure air change in every environment area or
carry out periodical ventilation by opening the areas.
Use the equipment away from heat sources or hot
surfaces. The equipment must not be used in explosion risk
environments (potentially explosive atmospheres). Before
using it, put the equipment on a levelled plane and secure
position, blocking it with suitable wheel stops.
Do not expose the tool to direct sunrays, heat sources, rain
and jets of water. Do not smoke near the equipment and
during operations (keep at a distance of at least 1 m).
The work area must be monitored by the operator while the
equipment is operating.
ATTENTION: R134a
fumes/gases are heavier than air and can gather on the floor
or inside cavities/holes and cause choke by reducing the
oxygen available for breathing.
At high temperatures, the refrigerant breaks down releasing
toxic and aggressive substances, harmful for the operator
and the environment. Avoid inhaling the system coolants
and oils. Exposure can irritate eyes and the respiratory tract.
ELECTRICAL CONNECTION: Connect the power cord
solely to a mains supply which conforms to the ratings on
the machine's nameplate (mounted on its side). Make sure
the mains socket is grounded.
Maximum impedance allowed in the point of connection to
the mains shall comply with standard EN 61000-3-11.
Starting currents can cause short voltage drops, which may
affect other equipments under unfavourable conditions. If
impedance in the point of connection to the mains is not
compliant, this may lead to interference so please consult
the electrical power network operator before connecting the
equipment.
Never use the service station with a defective power cord or
a different one from that supplied with the machine. If
damaged, immediately have it replaced with an original
spare part or equivalent by a MAHLE centre. Before
opening the service station, extract completely the supply
cable from the plug, or you can get an electric shock.
Do not tamper with or bypass the safety equipment and
settings.
Do not leave the machine powered up when not in use; shut
off the power supply before leaving the equipment unused
and/or R1234yf refrigerant
for a long time. Do not forget that the tool (pressure tool) must
always be protected.
REFRIGERANTS AND LUBRICANTS - PERSONAL SAFETY
EQUIPMENT AND PRECAUTIONS: The refrigerants and the
pressure cylinders have to be handled with care, otherwise there will
be possible health risks.
The operator must wear safety glasses, gloves and protective
clothing suitable to the work. Contact with the refrigerant can cause
blindness (eyes) and other physical damages (freezing) to the
operator. Avoid contact with the skin; the refrigerant's low boiling
point (approx. –26 °C for R134a and approx. -30 °C for R1234yf) can
cause freezing burns.
Further information about safety can be obtained from the safety
sheets of lubricant and refrigerant producers.
Do not inhale refrigerant or oil vapour. Keep away from the vent
valves and ventilation coupling, especially when non-condensable
gas is being vented.
Never direct the quick couplings (taps) towards your face or other
persons or animals.
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 pressurised 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.
