Symbol Warning to prevent injuries
ALLOW ONLY QUALIFIED PERSONNEL TO USE
THE STATION. Before starting the station, read and
follow the instructions and warnings contained in
this manual. The operator must be familiar with
air-conditioning and refrigeration systems, with
refrigerants and dangers of components under-
pressure. If the operator is unable to read this
manual, the use instructions and precautions should
be read and explained in his/her native language.
Use the station as illustrated in this manual. Using
the machine differently than as it was designed
compromises its functionality and invalid the
protections it is equipped with.
THE PRESSURIZED CYLINDER CONTAINS LIQUID
REFRIGERANT. Do not overfill the inner tank, as
it may cause an explosion and serious or fatal
injuries. Do not retrieve refrigerant in non reusable
containers; only use approved reusable containers
with high pressure safety valves.
FLEXIBLE HOSES MAY CONTAIN LIQUID
REFRIGERANT UNDER PRESSURE. Contact with
the refrigerant can cause injury, blindness and
skin freezing. Wear protective clothing that include
safety glasses and gloves. Disconnect the hoses
with extreme caution. Make sure that the step has
been completed before disconnecting the station,
to avoid refrigerant emissions in the atmosphere.
DO NOT INHALE REFRIGERANT OR LUBRICANT IN
THE FORM OF STEAM OR SPRAYED The refrigerant
R1234yf reduces the amount of oxygen available
for breathing, causing drowsiness and dizziness.
Exposure to high concentrations of R1234yf causes
asphyxia, ocular, nose, throat and lungs lesions
and may harm the central nervous system. Use
the station in places where there is a mechanical
ventilation system that completes the air exchange
at least once per hour. If accidental spillage from
the system occurs, ventilate the work area before
resuming operations.
DO NOT DISPERSE THE REFRIGERANT IN THE
ENVIRONMENT. This precaution is necessary to
prevent the presence of refrigerant in the working
environment.
The refrigerant R1234yf is heavier than air and
tends to concentrate in the pits of the workshop.
