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.
The system contains refrigerant and oil under pressure. The mixture of air and
oil at high temperature can lead to an explosion (Diesel effect). Avoid operating
with air.
System breakdown! Personal injuries! Only CO
2
and approved refrigeration
oils must be used. Remove refrigerant from both high- and low-pressure sides
with a suitable recovery unit before removing the compressor.
WARNING
CO
2
refrigerant! Danger of suffocation! Never release significant volumes
of CO
2
or the entire contents of the system into closed rooms. In case of closed
room, if possible, keep the room well ventilated and/or install a CO
2
detection
device. CO
2
is odourless and colourless, so it cannot be perceived directly in
case of emission.
WARNING
Leaking CO
2
refrigerant! Danger of dry ice formation! In case of system
leakage, the decreasing pressure in the system might cross the triple point of
carbon dioxide. Dry ice formation can block pipes & components. Unexpected
high pressure inside the system might occur.
WARNING
Earth leakage current! Danger of electric shock!
This product can cause
both AC and DC earth leakage current. To protect against both kinds of leakage
current it is recommended to use an AC/DC sensitive RCD on the power supply
side.
WARNING
High voltage! Danger of electric shock and/or system breakdown!
Disconnect and lock out power before servicing. Allow drive components to
electrically discharge before servicing. Respect the time according to drive
manual before servicing the drive. Use compressor with grounded system only.
Refer to original equipment wiring diagrams. Electrical connections must be
made by qualified electrical personnel.
WARNING
High surface temperature! Burning!
Do not touch the compressor or piping
until they have cooled down. Ensure that other materials in the area of the
compressor do not come into contact with it. Mark and secure accessible
sections.
WARNING
Dry ice formation! Frostbite!
Whenever a pressure drop with carbon dioxide
occurs, there is a risk of dry ice formation. There is a high risk of frostbite when
touching dry ice!
CAUTION
Overheating! Bearing damage!
Do not operate compressor without
refrigerant charge or without it being connected to the system.
CAUTION
Contact with PAG! Material damage!
PAG lubricant must be handled
carefully and the proper protective equipment (gloves, eye protection, etc.)
must be used at all times. PAG 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.
