Application guidance
While newer A2L refrigerants have been designed to
replace existing A1 refrigerants, certain performance
characteristics like discharge gas temperature, temper-
ature glide, oil miscability etc. may be different com-
pared to prior expectations. Contact BITZER for applic-
ation specific guidance.
3.2.1 Compressor and refrigeration system
requirements
The specifications are established in standards (e.g.
EN378). In view of the high requirements and product
liability, it is generally recommended to carry out the
risk assessment in cooperation with a notified body.
Depending on the design and the refrigerant charge, an
assessment according to EU Framework Directives
2014/34/EU and 1999/92/EC (ATEX 137) may be ne-
cessary.
DANGER
Fire hazard in the event of refrigerant leakage
and in the presence of an ignition source!
Avoid open fire and ignition sources in the en-
gine room and in the hazardous zone!
• Pay attention to the ignition point in air of the refri-
gerant used, see also EN378-1.
• Vent engine room according to EN378 or install an
extraction device.
• To open the pipelines, use only pipe cutters and no
open flame!
• Install components from which refrigerant may leak
(e.g. low and high pressure limiter or low and high
pressure cut-out) only outside the switch cabinet!
If the following safety regulations and adaptations are
observed, the standard compressors can be run with
refrigerants mentioned above of the A2L safety group.
• Observe the max. refrigerant charge according to the
installation place and the installation zone! See
EN378-1 and local regulations.
• No operation in the vacuum range! Install safety
devices for protection against insufficient and ex-
cessive pressure and make sure that they are de-
signed in accordance with the requirements of the
safety regulations (e.g. EN378-2).
• Avoid air penetration in the system – also during and
after maintenance work!

3.2.2

General operation requirements

Operation of the system and personal protection are
usually subject to national regulations on product
safety, operating safety and accident prevention. To
this end, separate agreements between the contractor
and the end user must be made. The provision of the
necessary risk assessment for work environment prior
to installation and operation of the system is the re-
sponsibility of the end user. To this end, cooperation
with a notified body is recommended.
• To open the pipelines, use only pipe cutters and no
open flame.

4.1 Transporting the compressor

Either transport the compressor screwed onto the pallet
or lift it using the eyebolts.
DANGER
Suspended load!
Do not step under the machine!
