Risk of burns on hot surfaces
On the compressor casing, pipelines and circuit components and on the oil sump
heater surface temperatures of far higher than 100 ° C may occur, which may cause
serious injuries. Wear the required personal protective equipment (protective gog-
gles, gloves, ...)
Prevention of risks due to contact with refrigerant
Physical contact with refrigerant must be strictly avoided as it can cause severe
frostbite and damage the retina - temperature range, for example R407C at ambi-
ent pressure is approximately - 44°C!
Prevent the risk of suffocation
Safety refrigerants are odourless and tasteless, can replace oxygen in a technical
room and cause suffocation (MAK - value 1000 ppm).
In case of refrigerant leaks leave immediately the affected room. Enter only with breathing pro-
-
tection or care for adequate ventilation.
Refrigerant is heavier than air and will collect at the lowest room point. For small refrigerant
-
charges, this risk is significantly reduced.
Refrigerant and compressor oil create as soon as in touch with open flame toxic substances.
-
Do not inhale!
-
Do not smoke in the technical room!
-
For more information refer to chapter 8.2.3 (Refrigerant).
2.2.3 ATEX units
General safety indications
ATEX units may not be used near:
-
High frequency sources (e.g. transmitter systems)
Strong light sources (e.g. laser beam systems)
-
-
Ionizing radiation sources (e.g. X-ray machine)
Ultrasound sources (e.g. ultrasound echo testing equipment)
-
Safety indications for the operation
The following instructions must be observed urgently for the safe operation of ATEX units:
Operating conditions in accordance to the intended use.
-
In the immediate environment of the unit no substances according to EN
-
1127-1:2011, which prone to spontaneous combustion, such as pyrophoric
substances.
Permanent and adequate ventilation of the installation room to prevent the
-
creation of an explosive atmosphere, which is caused by leakage.
-
Do not exceed the maximum permitted speed of the fan, as it could otherwise
lead to sparking.
-
Take measures to prevent any kind of ignition sources.
