Introduction
This supplement to the Operating Instructions SB-500
is limited to the special features of these compressors
concerning their use in potentially explosive areas
(compressors in a special explosion-proof design). In
addition to this, the Operating Instructions SB-500 are
applicable.
If these compressors are used, the use of an oil separ-
ator OA-EX in the system is required. For this reason,
the BITZER Operating Instructions DB-300 and DB-309
must also be adhered to.
According to the EU Machinery Directive 2006/42/EC
and the EU Pressure Equipment Directive 2014/68/EU,
these refrigeration compressors are designed for in-
stallation in machines located in areas that are subject
to the EU Explosion Protection Directive 2014/34/EU
(ATEX 114).
They may only be put into operation if they have been
installed according to the standard Operating Instruc-
tions SB-500, this supplement and the Operating In-
structions for oil separators DB-300 and DB-309 and if
the overall system complies with the applicable legal
provisions (applied standards: see declaration of incor-
poration).
The compressors have been designed especially for
the use in zones 1 and 2 (ATEX) according the EU Dir-
ective 1999/92/EC (ATEX 137) and comply with the re-
quirements of the ATEX marking Ex II 2G Ex h IIC T4
Gb X. They have been built in accordance with state-of-
the-art methods and current regulations. Particular im-
portance was placed on user safety.
The Ex-relevant information (zones, explosion groups,
temperature class, etc.) must be defined by the end
user and specified in an explosion protection docu-
ment.
Before putting the system into operation, the end user
must have the completed installation assessed and ac-
cepted by a notified body.
These Operating Instructions, the EU Declaration of
Conformity (type examination certificates) and the man-
ufacturer’s documentation of the components used
must be kept available in the vicinity of the refrigeration
system during the whole service life of the compressor.
