ULTIGAS 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.
