Information
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 let them dry, because they
may contain dissolved toxic substances. Never inhale
evaporation products. Let the concerned parts be
cleaned by trained staff or, if the parts are corroded,
dispose of them properly.
3.1.1 Compressor and refrigeration system
requirements
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 adaptions are ob-
served, the BITZER ECOLINE standard compressors
can be run with refrigerants of the A2L safety group.
Operation of BITZER VARISPEED compressors with
refrigerants of the A2L safety group only upon request.

• 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!
3.1.2

General operation requirements

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.

4 Mounting

Information
Observe tightening torques for screw fixings ac-
cording to maintenance instructions KW-100!

4.1 Transporting the compressor

Either transport the compressor screwed onto the pallet
or lift it on the eyebolts. Lift the tandem compressor
only with a lifting beam, see figure 1, page 7.
DANGER
Suspended load!
Do not step under the machine!
