user, are not allowed to do so and must call on an expert.
▪
The maximum refrigerant charge is specified in standards such as, but not limited to
EN 378, EN 60335-2-40 and EN 60335-2-89. The system designer shall implement all safety
measures defined by the applicable standards and shall not exceed the maximum
refrigerant charge.
▪
If a flammable atmosphere is detected, immediately take all necessary precautions to
mitigate the risk as determined in the risk assessment.
▪

1.3 General instructions
WARNING
Pressurized system! Serious personal injuries and/or system
breakdown!
Accidental system start before complete set-up must be avoided.
Never leave the system unattended without locking it out electrically when it is
on vacuum and has no refrigerant charge, when it has a holding charge of
nitrogen, or when the compressor service valves are closed.
WARNING
System breakdown! Personal injuries!
Only approved refrigerants and
refrigeration oils must be used.
WARNING
High shell temperature! Burning!
Do not touch the compressor until it has
cooled down. Ensure that other materials in the area of the compressor do not
come into contact with it. Lock and mark accessible sections.
CAUTION
Overheating! Bearing damage!
Do not operate compressors without
refrigerant charge or without being connected to the system.
CAUTION
Contact with POE! Material damage!
POE lubricant must be handled
carefully and the proper protective equipment (gloves, eye protection, etc.)
must be used at all times. POE must not come into contact with any surface
or material that it might damage, including without limitation, certain polymers,
eg, PVC/CPVC and polycarbonate.
IMPORTANT
Transit damage! Compressor malfunction!
Use original packaging. Avoid
collisions and tilting.
