- never expose the unit or operate it in acidic or wet
environments or close to open containers of inflammable
substances;
- the unit must operate in places with good ventilation;
- never alter the settings of the safety valves and control
systems;
- never use bottles or other storage containers that are not
approved and are not fitted with safety valves;
- never load any container over 80% of its maximum
capacity;
- never leave the unit powered if it is not to be used
immediately. Cut off the mains power supply when it is
not planned to use the equipment.
SAFETY STANDARDS
- always wear gloves and goggles when working with
refrigerant gases. Contact of refrigerant liquid with the
eyes can cause blindness;
- avoid all contact with skin (low boiling point -30
°C can
cause frostbite);
- never inhale the vapours of refrigerant gases;
- before connecting the station with a system or external
container, check that all the valves are closed;
- before disconnecting the station, check that the cycle is
over and all the valves are closed. This will prevent
dispersing refrigerant gas into the atmosphere;
The station is equipped with special fittings to avoid
contamination with systems using R12. Do not attempt to
adapt this unit for use with R12.
This station is exclusively for professionally trained
operators who must be familiar with refrigerating
systems,
refrigerant
gases
and
the
damage
pressurized equipment can cause, therefore:
