About these instructions

Read these instructions before assembly and before using the compressor. This will avoid misunder-

standings and prevent damage. Improper assembly and use of the compressor can result in 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 compres-

sor is installed.

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|Safety

These assembly instructions describe the standard version of the HG12P manufactured by GEA

Bock. The compressor is intended for use in refrigeration systems in compliance with the limits of

application.Onlytherefrigerantspeciedintheseinstructionsmaybeused.

Any other use of the compressor is prohibited!

The GEA Bock refrigerating compressor named in the title is intended for installing in a machine

(within the EU according to the EU Directives 2006/42/EC Machinery Directive, 97/23/EC Pressure

EquipmentDirectiveand2006/95/EC–LowVoltageDirective).

Commissioning is only permissible if the compressor has been installed in accordance with these

assembly instructions and the entire system into which it is integrated has been inspected and

approved in accordance with legal regulations.

1.4 Intended use

WARNING! The compressor may not be used in potentially

explosive environments!

ATTENTION! Compressor operation is possible within the operating limits

shown in the diagrams. Please note the signicance

of the shaded areas. Thresholds should not be selected as design

or continuous operation points.

- Permissible ambient temperature (-20°C) - (+60°C)

    -Max.permissibleswitchingfrequency8x/h.

- A minimum running time of 3 min. steady-state condition

(continuous operation) must be achieved.

For operation with additional cooling:

- Use only oils that are highly thermally stable.

- Avoid continuous operation near the limits.

Foroperationwithfrequencyconverter:

- The maximum current and power consumption must not be

exceeded.Inthecaseof operationabovethe mainsfrequency,

the application limit can therefore be limited.
