Introduction

TM
The Copeland Scroll compressor – using the compliance principle - has been under development at Copeland since
1979 and is the most efficient and durable compressor Copeland has ever developed for air-conditioning, refrigeration
and heat pump applications. It offers very low vibration and sound levels and is tolerant to stresses caused by liquid
slugging, flooded starts, and debris commonly found in refrigeration systems.
Available product range in this family is from 2.0 to 6 HP. For detailed information, please, refer to the Copeland
Selection Software accessible free of charge from the Copeland Website at www.ecopeland.com or printed
performance brochures.
These guidelines are not meant to replace the system expertise available from system manufacturers.

Nomenclature

The model numbers of Copeland Scroll compressors have been designed to include a coded nominal capacity at ARI
operating conditions in BTU/h at 60 Hz.
All refrigeration scroll compressors are charged with polyolester oil, which is indicated by the letter "E".

Qualified Refrigerants

R404A is qualified for all horizontal refrigeration scroll compressors.
ZBH compressors are also qualified to operate with R407C. R404A and R134a.
Data availability should be checked with Copeland Selection software.
It is essential that the glide with refrigerant blends (primarily R407C) be given careful consideration when adjusting
pressure and superheat controls.
