•
Always make sure that the units are accessible only to authorized and trained
technical personnel. If necessary, use appropriate equipment to keep unauthorized
persons away from the unit.
•
Have all leaks immediately eliminated by service personnel or a specialist
refrigeration company (refer to section 4.10).
•
The safety sheet stating the type of refrigerant charged on the given unit shall be
firmly secured in the machine room of the unit in a well visible manner (refer to unit
identification plate or operation manual for the unit).
•
Ensure that proper trays or similar vessels are mounted below the unit in order to
reliably capture oil and glycol liquids and prevent contact with the environment.
Warning of high concentration of refrigerants in the air!
High concentration of refrigerants in the air may have an anaesthetic effect and
cause unconsciousness. Prolonged exposure may cause irregular heartbeat and
sudden death. Very high concentration of refrigerant may cause suffocation by
reduced oxygen content in the surrounding air.
•
You should therefore only work in an adequately ventilated environment,
and exercise due care and attention when carrying out the work.
•
Wear protective clothing and, if necessary, an autonomous breathing
apparatus.
Smoking and open flames are prohibited
Smoking and open flames at the installation site of the unit or during work with
refrigerants are prohibited. Open fire or flames can lead to the disintegration of a
refrigerant and release of toxic gases.
•
Do not keep any inflammable liquids in close proximity to the unit.
Danger of injury from refrigeration!
Contact with a liquid refrigerant can result in skin burns or injury to other organs.
•
Exercise due caution and attention when carrying out jobs and avoid
contact with a refrigerant.
•
Wear suitable protective clothing.
Danger of injury caused by high pressure!
When working on hydraulic or refrigeration circuits or in case of damage to the
components or piping, there is a risk of injury from fluids or gases escaping at high
pressure.
•
Exercise due caution and attention when carrying out this work.
•
Wear appropriate protective clothing.
ATTENTION
Risk of environmental damage!
•
Do not pollute the environment with liquid products, refrigerants or oils.
•
Dispose of the latter in accordance with local laws and regulations by
avoiding harm to the environment.
Ethylene glycol and propylene glycol are categorized as water pollutants. This
also applies to mixtures with water.
