with 3.8 litres of oil.
2.6.2 Application limits
WARNING
Oil dilution due to low superheat! Compressor breakdown!
Low suction
superheat leads to oil dilution. Always operate the system with adequate
superheat to avoid viscosity decrease of the oil. Additional measures in
system design might help to avoid unacceptable lubrication conditions.
For application envelopes, please refer to the compressor application envelopes which can be found
in Copeland Select software, available at
www.climate.emerson.com/en-gb .
LOCU ref rigeration units can be used at ambient temperatures down to -15 °C. The application
envelopes of the units must be respected under all operating conditions. For lower ambient
temperatures please contact your local Application Engineering representative.
2.6.3 PED category
The PED category is assigned according to the Pressure Equipment Directive PED 2014/68/EU.
Requirements apply to the relevant pressure levels in the ref rigeration unit if a defined limit value of
pressure relative to the environment and relevant internal free volume is exceeded.
The calculation of the PED category is based on the fluid group (group 1: flammable or group 2: non-
f lammable) and on the vessel size. A differentiation must be made between the high- and low-
pressure sides. The highest of the calculation results is considered to determine the PED category.
LOCU ref rigeration units are operated with A1 refrigerants (fluid group 2).
