available for other refrigerants of the A2L safety group.
That is why the protection device has to be installed
outside the terminal box, for example in the switch cab-
inet, until specific approval has been obtained.

When using a flammable refrigerant:
Affix the warning sign "Warning: flammable ma-
terials" (W021 according to ISO7010) well vis-
ibly to the compressor. An adhesive label show-
ing this warning sign is enclosed with the Oper-
ating Instructions.
Refrigerant burning in the terminal box may only hap-
pen if several very rare errors occur at the same time.
The probability of this event occurring is extremely low.
When suspecting burnt refrigerant in the terminal box,
wait at least 30 minutes before opening it. According to
the present knowledge, this is the time needed for the
toxic combustion products to be degraded. It is neces-
sary to use appropriate, acid-resistant gloves. Do not
touch moist residues, but allow them to dry, because
they may contain dissolved toxic substances. Never in-
hale evaporation products. Have trained staff clean the
parts concerned or, if the parts are corroded, dispose of
them properly.

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.

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!

Operation of the system and personal protection are
usually subject to national regulations on product
safety, operating reliability 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.
