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.

These assembly instructions describe the standard version of the compressors named in the ti- tle manufactured by Bock. Bock refrigerating compressors are intended for installing in a machine (within the EU according to the EU Directives 2006/42/EC Machinery Directive and 2014/68/EU Pressure Equipment Directive). -
Page 6: Product Description
2 | Product description 2.1 Short description • Semi-hermetic four-cylinder reciprocating compressor with suction gas cooled driving motor. • T he flow of refrigerant sucked in from the evaporator is led over the engine and provides for a particularly intensive cooling. Thus the engine can be kept on a relatively low temperature level specially during high load. • Oil pump independent of direction of rotation for reliable and safe oil supply. • O ne decompression valve each on the low and high pressure side, which vent into the atmos- phere when inadmissibly high pressure levels are reached.

Page 11: Pipes
4 | Compressor assembly Tube preparation: The tube has to be sawn in a right angle. An angular tolerance of ± 1° is permissible. Slightly trim the pipe ends inside and outside. For thin walled steel pipes or soft pipes made of nonferrous metal, reinforcing sleeves have to be used. Pipe assembly: Push union nut (5) and cutting ring (3) onto pipe (2). Insert pipe into socket (6) as far as it will go and firmly press against pipe stop, otherwise incorrect assembly. Hand tighten union nut until socket, cutting ring and union nut are locked. Tighten union nut 1 turns using a spanner wrench. The cutting ring is noticeably locked to the socket face (for assembly inside pipe connection, hold up valve with a spanner wrench). This should cause the cutting ring with its cutting edges (1) to cut into the pipe resulting in a visible collar. In order to stick to the turns we recommend using marking lines on union nut and pipe. After assembly, it is necessary to check the collar. The gasket must not be... -
Page 12: Laying Suction And Pressure Lines
4 | Compressor assembly 4.7 Laying suction and pressure lines ATTENTION Property damage possible. Improperly installed pipes can cause cracks and tears which can result in a loss of refrigerant. INFO Proper layout of the suction and pressure lines directly after the compressor is integral to the smooth running and vibration behaviour of the system. -
Page 13: Operating Mode Of The Lockable Service Connections
Opening the service connection Compressor 1 / 2 Spindle: Turn - 1 turn to the right clockwise. —> Service connection opened / shut-off valve opened. The connection which cannot be shut off is intended for safety devices. After activating the spindle, generally fit the spindle protection cap again and tighten with 40 - 50 Nm. This serves as a second sealing feature during operation. 4.10 Oil return To ensure the oil return function will work reliably no matter what kind of system configuration you are using, Bock recommends incorporating oil separators or oil level monitoring equipment. The "O" connection is already available from the factory for the purpose of installing the additional oil level monitoring component. Oil should be returned from the oil separator to the compressor via the "D1" connection provided for this purpose on the compressor. 4.11 Suction pipe filter For systems with long pipes and higher degree of contamination, a filter on the suction-side is recommended. The filter has to be be renewed depending on the degree of contamina- tion (reduced pressure loss). -

ATTENTION When attaching accessories with an electrical cable, a minimum bending radius of 3 x the cable diameter must be maintained for laying the cable. -
Page 15: Standard Motor, Designed For Direct Or Part Winding Start
5 | Electrical connection 5.2 Standard motor, designed for direct or part winding start Designation on the name plate Y/YY Compressors marked in this way are suitable for direct or part winding start. The motor winding is divided into two parts: part winding 1 = 50 % and part winding 2 = 50 %. This winding division reduces the start-up current during a part winding start to approx. 50 % of the value for a direct start. Not possible on compressors with LSPM Motor! In the factory, the motor is switched for direct starting (YY). For part winding start (Y/YY), remove the bridges and connect the motor feed cable according to the circuit diagram: 400 V Direct start YY Part winding start Y/YY PW II PW I ATTENTION Property damage possible. -

Page 22: Electronic Trigger Unit Int69 G
5 | Electrical connection 5.6 Electronic trigger unit INT69 G The compressor motor is fitted with cold conductor temperature sensors (PTC) connected to the electronic trigger unit INT69 G in the terminal box. In case of excess temperature in the motor winding, the INT69 G deactivates the motor contactor. Once cooled, it can be restarted only if the electronic lock of the output relay (terminals B1 + B2) is released by interrupting the supply voltage. -

ATTENTION The oil sump heater must generally be connected and operated! Operation: The oil sump heater operates when the compressor is at a standstill. -

The compressor has undergone trials in the factory and all functions have been tested. There are therefore no special running-in instructions. -
Page 25: Evacuation
6 | Commissioning 6.4 Evacuation ATTENTION Do not start the compressor if it is under vacuum. Do not apply any voltage - even for test purposes (must only be operated with refrigerant). Under vacuum, the spark-over and creepage current distances of the terminal board connection bolts shorten; this can result in winding and terminal board damage. First evacuate the system and then include the compressor in the evacuation process. Relieve the compressor pressure. -
Page 26: Start-Up
6 | Commissioning 6.6 Start-up WARNING Ensure that both shut-off valves are open before starting the compressor! Check that the safety and protection devices (pressure switch, motor protection, electrical contact protection measures, etc.) are functioning properly. Switch on the compressor and let it run for at least 10 minutes. The machine should reach a state of equilibrium. Check the oil level: The oil level must be visible in the sight glass. After a compressor is replaced, the oil level must be checked again. If the level is too high, oil must be drained off (danger of oil liquid shocks; reduced capacity of the refrigerating system). ATTENTION If larger quantities of oil have to be topped up, there is a risk of oil impact effects. -
Page 27: Decompression Valves
6 | Commissioning 6.8 Decompression valves ATTENTION The compressor is fitted with two decompression valves. One valve each on the suction and discharge side. If excessive pressures are reached, the valves open and prevent further pressure increase. Thereby CO is blown off to the ambient! In the event that a pressure relief valve activates repeatedly, check valve and replace if necessary as during blow-off extreme con- ditions can occur, which may result in a permanent leak. -
Page 28: Avoiding Slugging
6 | Commissioning 6.9 Avoiding slugging ATTENTION Slugging can result in damage to the compressor and cause refrigerant to leak. To prevent slugging: The complete refrigeration plant must be properly designed. All components must be compatibly rated with each other with regard to output (particularly the evaporator and expansion valves). Suction gas superheating at the compressor input should be > 10 K (check the setting of the expansion valve). Regard oil temperature and pressure gas temperature. (The pressure gas temperature has to be high enough min. 50 °C, so the oil temperature is > 30 °C). The system must reach a state of equilibrium. P articularly in critical systems (e.g. several evaporator points), measures such as the use of liquid traps, solenoid valve in the liquid line, etc. are recommended. There should be no movement of refrigerant in the compressor while the system is at a standstill. -
