3.1.2Personal safety information
The Brain Bee MULTIGAS 8500 PLUS A/C service station is particularly simple and reliable due to
its adjustments and functions. When used correctly it presents no hazard for the operator, on
condition that he observes the following general safety instructions and that the service station is
regularly serviced (incorrect maintenance/use compromise the equipment's safety).
Before operating the service station for the first time, read these instructions carefully. If any part
of the instructions is unclear, contact your reseller or the Brain Bee head offices in Parma.
This service station may be used by only one equipment operator, familiar with A/C and
refrigeration systems and the hazards associated with refrigerants and high pressure equipment.
WORKPLACE: The equipment must be operated in the open or in a well-ventilated location (at
least 1 air change per hour). The workshop has to be equipped with ventilation systems able to

ENGLISH 9 / 77 CAP. 3 - SAFETY CONDITIONS
MULTIGAS
8500 PLUS
ensure the air change in every environment area or to carry out a periodical ventilation by
opening the environment areas. Use the tool away from heat sources or hot surfaces. The tool
has not to be used in explosion risk environments (potentially explosive atmospheres). Before
using it, put the tool 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 close
to 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: the R134a and/or R1234yf refrigerant 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. The
exposure can irritate eyes and the respiratory tract.
ELECTRICAL CONNECTION: Connect the power cord solely to a mains supply which conforms
with the ratings on the machine's nameplate (mounted on its side). Make sure the mains socket is
grounded.
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 or equivalent
by a Brain Bee S.p.A. service 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 for a long time. Do not forget that the tool (pressure tool) must always be
protected.

CAP. 3 - SAFETY CONDITIONS 10 / 77 ENGLISH
MULTIGAS 8500 PLUS
REFRIGERANTS AND LUBRICANTS - INDIVIDUAL SAFETY EQUIPMENT AND PRECAUTIONS: The
refrigerants and the pressure vessels 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. The
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 gases. The mixture with other types of refrigerant produces serious damages
to the conditioning and cooling systems. Mixed gases have to be disposed of according to the
current regulations. Never use MULTIGAS 8500 PLUS equipment with systems containing
compressed air, mixtures of R134a or R1234yf with air or oxygen may be potentially flammable.
Do not modify the calibration of safety devices. Do not remove the seals of the safety valves and
of the control systems. Do not use external tanks or other storage containers that are not
homologated or without safety valves.
Make sure the equipment's aeration and ventilation ports are not obstructed or covered while the
equipment is operating.
