CAP. 3 - SAFETY CONDITIONS 10 / 73 ENGLISH
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 the contact with skin; the low boiling temperature (about –26 °C for R134a)
may cause 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: Use only pure R134a refrigerant, and do not
use it on vehicles containing other types of refrigerants. 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. Do not use the 9000 BUS PLUS station with
compressed air systems.
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.
