▶ Protect the pipelines against damage.
▶ 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!
▶ Only use tools and devices that are suitable for A2L
refrigerants. See also A-541 (HTML).
If the following safety regulations and adaptations are
complied with, the standard compressors can be oper-
ated with the specified refrigerants of the A2L safety
group.
• Observe the max. refrigerant charge according to
place of installation and installation area! See
EN378-1 and local regulations.
• No operation in vacuum range! Install safety devices
for protection against insufficient and also excessive
pressure and make sure that they are designed in
accordance with the requirements of the safety regu-
lations (e.g. EN378-2).
• Prevent air penetration into 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, operational reliability and accident prevention.
This requires separate agreements to be made
between the system manufacturer and the end user.
Implementation of the required risk assessment for in-
stallation and operation of the system is the responsibil-
ity of the end user. To this end, cooperation with a noti-
fied body is recommended.
To open the pipes, use only pipe cutters; do not use an
open flame.
When using flammable refrigerants of safety group
A2L, additions, changes and repairs of the electrical
system are only possible to a limited extent and must
be subject to a risk assessment by the customer.

Mounting
4.1
Transporting the compressor
Either transport the compressor screwed on the pallet
or lift it using the lifting eyes.
Weight approx. 550 .. 1160 kg (depending on the
model)
DANGER
Suspended load!
Do not step under the machine!
Where possible, use the two-point suspension system
to lift the compressor.
Fig. 1: Standard: Lifting the compressor, two-point suspension: Ex-
ample HS.85
Fig. 2: Option: Lifting the compressor, single-point suspension: Ex-
ample HS.95
4.2
Installing the compressor
▶ Install and mount the compressor horizontally.
▶ In case of outdoor installation: Use a weather protec-
tion.
