1.2 Safety statements
Refrigerant compressors must be employed only for their intended use. The system has
to be labelled according to the applicable standards and legislation.
Only qualified and authorized RACHP (refrigeration, air conditioning and heat pump
personnel) are permitted to install, commission and maintain this equipment. Only
competent personnel (as specified in EN 13313) qualified for flammable refrigerant
handling is permitted to commission, initiate and maintain the compressor/refrigeration
systems; non-trained personnel, including the user, are not allowed to do so and must call
on an expert.
When planning and building systems, a risk assessment and corresponding precautions
for a risk mitigation must be taken by the system designer. When dealing with A2L and A3
refrigerants, special attention must be paid to flammability.
The maximum refrigerant charge is specified in standards such as, but not limited to
EN 378. The system designer shall implement all safety measures defined by the
applicable standards and the maximum refrigerant charge shall not be exceeded.
Electrical connections must be made by qualified electrical personnel.
All valid standards for connecting electrical and refrigeration equipment must be
observed.
The national legislation and regulations regarding personnel protection must be observed.
Use personal safety equipment. Safety goggles, gloves, protective
clothing, safety boots and hard hats should be worn where necessary.
1.3 General instructions

breakdown! Accidental system start before complete set-
Never leave the system unattended without locking it out electrically when it is
on vacuum and has no ref rigerant charge, when it has a holding charge of
nitrogen, or when the compressor serv

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
Diesel effect! Compressor destruction!
The system contains refrigerant
and oil under pressure.
The mixture of air and oil at high temperature can lead
to an explosion. Avoid operating with air.
WARNING
System breakdown! Personal injuries!
Only approved refrigerants and
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.
Contact with refrigerant oil! Material damage!
Polyolester oil (POE) and
poly-
alkylene glycol (PAG) lubricant must be handled carefully and the proper
protective equipment (gloves
, eye protection, etc.) must be used at all times.
Refrigerant oil must not come into contact with any surface or material that it
might damage, including but without limitation, certain polymers, eg,
PVC/CPVC and polycarbonate.
