4.1 Safety rules
 The device described in this manual is to be used only by qualified employees, who are
required to know the basics of refrigeration industry, cooling systems and refrigerants
and have knowledge concerning possible damages that may be caused by
pressurized equipment.
 Users are requested to carefully read this manual to assure proper and reliable use of
the device .
 use only refrigerant marked as R134a. Mixing the refrigerant with other refrigerating
media may result in serious damage to the air-conditioning and refrigerating
installations and to the service hardware.
 It is recommended that appropriate personal protective equipment, such as goggles
and gloves is used as the contact with the refrigerant may result in bodily damage and
even loosing one’s sight.
 Avoid skin contact as low boiling point (approx -30
o
C) may cause frostbite.
 Avoid inhaling refrigerant vapors.
 Before connecting the unit to the air-conditioning installation or external tank, check if
all valves are closed.
 Before disconnecting the unit check if all operations were finished and if all valves al

 All flexible parts (hoses) may contain pressurized refrigerant:
Be extremely careful when disconnecting hoses and tubes
 Service equipment and vehicle air-conditioning systems using R134a refrigerant should
not be checked using compressed air. Certain R134a-air mixes turn out to be
inflammable in high pressure conditions. Such mixes may be dangerous and may
create potential fire and explosion risk causing injuries to people and damages to
property. For more information on hazards, refer to lubricants and refrigerants
manufacturers.
