1 Introduction

BITZER reciprocating compressors which are intended
for use with chlorine-free HFC and HFO refrigerants
(R134a, R404A, R407A/C/F, R407C, R507A, R1234yf,
R513A, R450A etc.) are charged with a high-quality
polyolester oil. A "Y" is added to the type designation of
the compressor, for example 4CES-6Y.
The BITZER BSE32 and BSE55 polyolester oils are
subject to the BITZER quality management and are op-
timized for BITZER reciprocating compressors. Their
chemical compatibility also with modern construction
materials and new refrigerants has been extensively
tested and approved. BITZER polyolester oils signific-
antly exceed the requirements of DIN 51503, Part 1, for
refrigeration compressor oils with respect to water con-
tent and total acid number (TAN).
Contrary to conventional lubricants, BSE32 and BSE55
provide good solubility in HFC and HFO refrigerants
and are therefore especially suitable for operation with
these substances. Moreover they have outstanding lub-
rication characteristics and a favourable viscosity per-
formance (high viscosity index).

2 Safety

2.1 Authorized staff

All work done on compressors and refrigeration sys-
tems may only be performed by qualified and author-
ized staff who have been trained and instructed accord-
ingly. The qualification and expert knowledge of the
personnel must correspond to the local regulations and
guidelines.

2.2 Residual risks

The compressor may present unavoidable residual
risks. That is why any person working on this device
must carefully read these Operating Instructions.
The following rules and regulations are mandatory:
• relevant safety regulations and standards (e.g. EN
378, EN 60204 and EN 60335),
• generally accepted safety rules,
• EU directives,
• national regulations.

General safety references

State of delivery
CAUTION
The compressor is filled with a holding charge:
Excess pressure 0.2 .. 0.5 bar.
Risk of injury to skin and eyes.
Depressurize the compressor!
Wear safety goggles!
For work on the compressor once it has been
commissioned
WARNING
The compressor is under pressure!
Serious injuries are possible.
Depressurize the compressor!
Wear safety goggles!
CAUTION
Surface temperatures of more than 60°C or be-
low 0°C.
Risk of burns or frostbite.
Close off accessible areas and mark them.
Before performing any work on the compressor:
switch it off and let it cool down.
