About these guidelines
The purpose of these guidelines is to provide guidance in the application of Copeland™ scroll
compressors in users' systems. They are intended to answer the questions raised while designing,
assembling and operating a system with these products.
Besides the support they provide, the instructions listed herein are also critical for the proper and
safe functioning of the compressors. The performance and reliability of the product may be impacted
if the product is not used according to these guidelines or is misused.
These application guidelines cover stationary applications only. For mobile applications, please
contact the Application Engineering department at Emerson as other considerations may apply.

Safety instructions
Copeland scroll compressors are manufactured according to the latest relevant European, UK and
US safety standards. Particular emphasis has been placed on the user's safety.
ZB*KCU compressors are intended for installation in systems in accordance with the following
directives and regulations:
Machinery Directive MD 2006/42/EC
Pressure Equipment Directive PED 2014/68/EU
Low Voltage Directive LVD 2014/35/EU
They may be put to service only if they have been installed in systems according to instructions and
conform to the corresponding provisions of legislation.
In order to keep the system compliant with the ATEX Directive 99/92/EC, all accessories to be fitted
on the compressor, eg, oil level regulator, crankcase heater, discharge line thermostat, shall comply
with the ATEX Directive 2014/34/EU Zone 2. If one of these accessories does not comply, the
complete system will lose its compliance with the ATEX Directive 99/92/EC and therefore can be
operated only in a non-flammable environment.
NOTE: Only dedicated compressors are allowed to be used with flammable refrigerants.
Emerson marks all compressors that are qualified for flammable refrigerants with a sticker
indicating the usage of such refrigerants. Systems using flammable refrigerants must be
executed correctly while observing safety rules, as specified in corresponding safety
standards such as, but not limited to EN 378. They must comply with any and all applicable
legislation and regulations. Ensuring compliance remains the user's responsibility.
The Material Safety Datasheet (MSDS) of the refrigerant shall be considered – please check the
document provided by the gas supplier.
These instructions shall be retained throughout the lifetime of the compressor.
You are strongly advised to follow these safety instructions.
