WARNING!
Avoid body contact with descaling agents, as it can cause chemical burns and se-
rious eye damage. When handling descaling agents, wear appropriate protective
clothing (e.g. gloves, goggles etc.) and ventilate the room well.
Prevention of hazards caused by the sudden detachment of door panels while handling re-
movable panels
WARNING!
Removable door panels can fall out suddenly after detaching the connections and
can lead to injuries. Particular care should be taken when removing pressure sided
doors because they can be firmly in place and then suddenly detach. The user
must be able to carry the weight of the door. Two persons are needed when han-
dling doors with a surface of > 0.5 m²
Please note the instructions on the AHU and follow subsequent instructions exactly.
2.3.2 Refrigeration circuit
Preventing the risk of exceeding the maximum operating pressures PS
WARNING!
Never exceed the maximum operating pressures PS, which are specified on the
type plate (even not for test purposes). Damage may limit the security, effective-
ness and lifetime of the system. Never operate the refrigeration system with a
closed discharge line valve.
Risk of burns on hot surfaces
WARNING!
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 (protec-
tive goggles, gloves, etc.).
Prevention of risks due to contact with refrigerant
WARNING!
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
DANGER!
Safety refrigerants are odorless, tasteless and can contaminate the air and cause
suffocation (MAK - value 1000 ppm).
-
In case of refrigerant leaks, immediately leave the affected room. Enter only with breathing pro-
tection and ensure 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 react as soon as they come into touch with open flame toxic
substances. Do not inhale!
-
Do not smoke in the technical room!
