Safety Statements; General Instructions - Emerson Copeland YBD17K1E Manual

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.
▪ 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.
NOTE: For systems using A1 refrigerants (R404A, R407A, R407F, R448A, R449A, R407C,
R513A, R134a and R450A) the flammable refrigerant sticker is not of application and should
be removed from the compressor.
Additional requirements and statements for A2L refrigerant compressors/systems:
▪ Only competent personnel (as specified in EN 13313) qualified for flammable refrigerant
handling are permitted to commission, initiate and maintain the compressor/refrigeration
systems using flammable refrigerant; non-trained personnel, including the user, are not
allowed to do so and must call on an expert.
▪ When planning and building systems with such refrigerants, a risk assessment and
corresponding precautions for risk mitigation must be taken by the system designer.
Special attention must be paid to flammability when dealing with A2L refrigerants.
▪ 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 the maximum refrigerant charge shall
not be exceeded.
▪ If a flammable atmosphere is detected, immediately take all necessary precautions to
mitigate the risk as determined in the risk assessment.

General instructions

WARNING
Pressurized
breakdown! Accidental system start before complete set-up must be avoided.
Never leave the system unattended without locking it out electrically when it is
under 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 compressor without
refrigerant charge or without it being connected to the system.
CAUTION
Contact with refrigerant oil! Material damage! Polyolester (POE) 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 without
limitation, certain polymers, eg, PVC/CPVC and polycarbonate.
IMPORTANT
Transit damage! Compressor malfunction! Use original packaging. Avoid
collisions and tilting.
2
Use personal safety equipment.
clothing, safety boots and hard hats should be worn where necessary.
system! Serious personal
Safety goggles, gloves, protective
injuries and/or system
