About these instructions
Read these instructions before assembly and before using the compressor. This will avoid
misunderstandings and prevent damage. Improper assembly and use of the compressor can lead to
serious or fatal injury.
Observe the safety instructions contained in these instructions.
These instructions must be passed onto the end customer along with the unit in which the
compressor is installed.

1.2 Qualicationsrequiredofpersonnel
WARNING! Inadequately qualied personnel poses the risk of accidents, the
consequence being serious or fatal injury. Work on compressors
mustthereforeonlybeperformedbypersonnelwiththequalica-
tions listed below:
• For example, a refrigeration technician, refrigeration mechatron-
ics engineer. As well as professions with comparable training, which
enable personnel to assemble, install, maintain and repair refrigeration
and air-conditioning systems. Personnel must be capable of assessing
thework to be carried out and recognising any potential dangers.

1.3 General safety instructions
WARNING Riskofaccidents.
Refrigerating compressors are pressurised machines and as such
call for heightened caution and care in handling.
The maximum permissible overpressure must not be exceeded,
even for testing purposes.
Riskofburns!
- Dependingontheoperatingconditions,surfacetemperaturesof
over 60°C on the discharge side or below 0°C on the suction side
can be reached.
- Avoid contact with refrigerant necessarily.
Contactwithrefrigerantcancausesevereburnsandskin
damage.
1.4 Intended use
WARNING The compressor may not be used in potentially explosive
environments!
These assembly instructions describe the standard version of the compressor named in the title
manufactured by Bock. Bock refrigerating compressors are intended for installation in a machine
(within the EU according to the EU Directives 2006/42/EC Machinery Directive and 2014/68/EU Pres-
sureEquipmentDirective).
Commissioning is permissible only if the compressor has been installed in accordance with these as-
sembly instructions and the entire system into which it is integrated has been inspected and approved
in accordance with legal regulations.
The compressors are intended for use in refrigeration systems in compliance with the limits of
application.
Onlytherefrigerantspeciedintheseinstructionsmaybeused.
Any other use of the compressor is prohibited!

ATTENTION! For operation with capacity regulator:
- Continuousoperation,whenthecapacityregulatorisactivated,
is not permissible and can cause damage to the compressor.
- The suction gas superheat temperature may need to be reduced
or set individually when operating near to the threshold.
- When the capacity regulator is activated, the gas velocity in
the system can not under certain circumstances ensure that
sufcientoilistransportedbacktothecompressor.
When operating in the vacuum range, there is a danger of air
enteringonthesuctionside.Thiscancausechemicalreactions,
a pressure rise in the condenser and an elevated compressed-gas
temperature. Prevent the ingress of air at all costs!
