AIR CONDITIONING - Rafstjorn

· eliminate pressure from the entire cooling system before brazing or welding. Welding
when the circuit is under pressure is extremely dangerous due to the risk of the piping
rupturing and molten material being projected by the refrigerant gas pressure.
21.5 HAZARDS ARISING IN CASE OF FIRE
There are no direct dangers.
The refrigerant gas, in the presence of flames, generates toxic and corrosive substances.
The way to prevent this risk, in view of the relatively small quantities of refrigerant contained
in the machine, is to position the unit in adequately ventilated rooms.
21.6 TOXIC SUBSTANCES
The gas contained and used in this product is an ecological type of gas. A very small
quantity is used and the circuit is hermetically sealed.
All leaks with a loss of more than 15 grams per year are checked and eliminated during
testing.
The producer of the refrigerant gas states that gas concentrations inferior to 1 to 1000 are
non toxic. When the machine is not installed in a well-ventilated or suitably large room and
there is a substantial leak of refrigerant then the room should be ventilated and personnel
should be sent out from the room.
21.7 HAZARDOUS FLUIDS
The unit does not contain any fluids which are hazardous to people.
During operation, the A/C unit produces condensate which is drained into the environment
if it is not dissipated by the dissipator. It is recommended to drain this fluid adequately by
condensate lines so as to prevent possible hazards to people in the area.
