CAUTION
Failure to follow the instructions below may cause injury or severe accidents.
It is absolutely forbidden to weld, braze, cut, grind, or search for a possible leak with an open flame
on a circuit containing A3 refrigerant fluid. Any intervention of this type must become the subject of a
risk analysis.
The equipment (detectors, vacuum pump, etc.) must be compatible with flammable fluids.
Before powering up and operating the unit, always perform refrigerant detection using a suitable
calibrated detector to make sure there is no gas around the unit.
If refrigerant gas leaks out, avoid entering the room, ventilate it as soon as possible and as much as
possible, and prohibit any source of active ignition.
During maintenance, we recommend that operators be equipped with suitable Personal Protective
Equipment (helmet, gloves, goggles, etc.), cut off the power supply and not approach with a potential
source of ignition without first checking that there is no potentially flammable area due to an
undetected leak. With suitable electrical and non-electrical equipment located in ATEX, he will be
able to ventilate the cold chamber to ensure that his intervention is safe.
