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.

pressurized refrigerant systems:

• For example, a refrigeration technician, refrigeration mechatronic

engineer. As well as professions with comparable training, which

enables personnel to assemble, install, maintain and repair

refrigeration and air-conditioning systems. Personnel must be capable

of assessing the work to be carried out and recognising any potential

dangers.

1.3 General safety instructions

WARNING Risk of accidents.

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.

Risk of burns!

- Depending on the operating conditions, surface temperatures of

over 60°C on the discharge side or below 0°C on the suction side

can be reached.

- Avoid contact with refrigerant necessarily.

Contact with refrigerant can cause severe burns and skin

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-

sureEquipmentDirective).

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.

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

Any other use of the compressor is prohibited!

ATTENTION! Compressor operation is possible within the operating limits.

These can be found in Bock compressor selection tool (VAP)

under vap.bock.de. Observe the information given there.

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

(continuous operation) must be achieved.

For operation with supplementary cooling:

- Use only oils with high thermal stability.

- Avoid continuous operation near the limits.

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

- The potential control range of the compressor is 30-70 Hz.

- Max. permissible current consumption must not be exceeded.

At max. rotation speed therefore, the application limit can

be reduced.

- Use a thermal protection thermostat.

- Do not operate an additional capacity controller.

3.3 Limits of application

ATTENTION! When operating in the vacuum range, there is a danger of air

entering on the suction side. This can cause chemical reactions,

a pressure rise in the condenser and an elevated compressed-

gas temperature. Prevent the ingress of air at all costs!

Max. permissible operating pressure (LP/HP)1):

19/28 bar

1) LP = Low pressure

HP = High pressure
