Qualifications required of personnel

WARNING
Inadequately qualified personnel poses the risk of accidents, the consequence being serious or fatal injury. Work on compressors is therefore reserved for personnel which is qualified to work on 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.

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.

• Danger of suffocation.
  CO2 is a non-flammable, acidic, colorless and odorless gas and heavier than air.
  Never release significant volumes of CO2 or the entire contents of the system into closed rooms!
  Safety installations are designed or adjusted in accordance with
  EN 378-2 or appropriate safety standards.

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, 2014/68/EU Pressure
Equipment Directive). Commissioning is permissible only 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.
The compressor is intended for use with CO2 in sub-critical systems in compliance with the limits of application.
Only the refrigerant specified in these instructions may be used. Any other use of the compressor is prohibited!

Product description

Short description

• Semi-hermetic two-cylinder reciprocating compressor with suction gas cooled drive motor.
• The 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 special during high load on a relatively low temperature level.
• Oil pump independent of direction of rotation for reliable and safe oil supply
• One decompression valve each on the low and high pressure side, which vent into the atmosphere when these inadmissibly high printing pressures are reached.

Areas of application

Refrigerants
CO2: R744 (Recommendation CO2 quality 4.5 (< 5 ppm H2O))

Oil charge
The compressors are filled at the factory with the following oil type: BOCKlub E85 (only this oils may be used)

ATTENTION Property damage possible. The oil level must be in the visible part of the sight glass; damage to the compressor is possible if overfilled or underfilled!

Limits of application

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.

• Permissible ambient temperature (-20°C) – (+60°C).
• Max. permissible discharge end temperature 160°C.
• Min. oil temperature ≥ 30°C.
• Min. pressure gas temperature ≥ 50°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 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. (For more on the frequency converter, see chapter 5.8, p. 17 )

Compressor assembly

INFO
New compressors are factory-filled with inert gas. Leave this service charge in the compressor for as long as possible and prevent the ingress of air. Check the compressor for transport damage before starting any work.

Storage and transportation

• Storage at (-30°C) – (+70°C), maximum permissible relative humidity 10% -95 %, no condensation.
• Do not store in a corrosive, dusty, vaporous atmosphere or in a combustible environment.
• Use transport eyelet.
• Do not lift manually!
• Use lifting gear!

Setting up

ATTENTION Attachments (e.g. pipe holders, additional units, fastening parts, etc.) directly to the compressor are not permissible!

• Provide adequate clearance for maintenance work.
• Ensure adequate compressor ventilation.
• Do not use in a corrosive, dusty, damp atmosphere or a combustible environment.
• Setup on an even surface or frame with sufficient load-bearing capacity. Only erect on a slant in consultation with the manufacturer. Single compressor preferably on vibration damper.
• Duplex and parallel circuits always rigid.

Pipe connections

ATTENTION Damage possible.

• Superheating can damage the valve.
• Remove the pipe supports therefore from the valve for soldering and accordingly cool the valve body during and after soldering.
• Only solder using inert gas to inhibit oxidation products (scale).
• Material soldering/welding connection suction valve: S235JR
• Material soldering/welding connection discharge valve: P250GH
• The pipe connections have graduated inside diameters so that pipes with standart millimetre and inch dimensions can be used.
• The connection diameters of the shut-off valves are rated for maximum compressor output. The actual required pipe cross section must be matched to the output. The same applies for non-return valves.

Pipes

• Pipes and system components must be clean and dry inside and free of scale, swarf and layers of rust and phosphate. Only use air-tight parts.
• Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being cracked and broken by severe vibrations.
• Ensure a proper oil return.
• Keep pressure losses to an absolute minimum.

Laying suction and pressure lines

ATTENTION Property damage possible. Improperly installed pipes can cause cracks and tears, the result being a loss of refrigerant.

INFO Proper layout of the suction and discharge lines directly after the compressor is integral to the system’s smooth running and vibration behaviour.

A rule of thumb: Always lay the first pipe section starting from the shut-off valve downwards and parallel to the drive shaft.

Operating the shut-off valves

• Before opening or closing the shut-off valve, release the valve spindle seal by approx. ¼ of a turn counter-clockwise.
• After activating the shut-off valve, re-tighten the adjustable valve spindle seal clockwise.

Operating mode of the lockable service connections

After activating the spindle, generally fit the spindle protection cap again and tighten with 14-16 Nm. This serves as a second sealing feature during operation.

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 contamination (reduced pressure loss).

Electrical connection

DANGER Risk of electric shock! High voltage!
Only carry out work when the electrical system is disconnected from the power supply!

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.

INFO Connect the compressor motor in accordance with the circuit diagram (see inside of terminal box).

• Use suitable cable entry point of the correct protection type (see name plate) for routing cables into the terminal box. Insert the strain reliefs and prevent chafe marks on the cables.
• Compare the voltage and frequency values with the data for the mains power supply.
• Only connect the motor if these values are the same.

Information for contactor and motor contactor selection
All protection equipment, switching and monitoring devices must comply with the local safety regulations and established specifications (e.g. VDE) as well as the manufacturer’s specifications. Motor protection switches are required! Motor contactors, feed lines, fuses and motor protection switches must be rated according to the maximum operating current (see name plate). For motor protection, use a current-independent, time-delayed overload protection device for monitoring all three phases. Adjust the overload protection device so that it must be actuated within 2 hours at 1.2 times the maximum working current.

Connection of the driving motor
The compressor is designed with a motor for star-delta circuits.

INFO The connection examples shown refer to the standard version. In the case of special voltages, the instructions affixe terminal box apply.

Circuit diagramm for direct start 230 V ∆ / 400 V Y

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.
The hot gas side of the compressor can also be protected against overtemperature using thermal protection thermostats (accessory).
The unit trips when an overload or inadmissible operating conditions occur. Find and remedy the cause.

INFO The relay switching output is executed as a floating changeover contact. This electrical circuit operates according to the quiescent current principle, i.e. the relay drops into a the idle position and deactivates the motor contactor even in case of a sensor break or open circuit.

Connection of the trigger unit INT69 G

INFO Connect the trigger unit INT69 G in accordance with the circuit diagram. Protect the trigger unit with a delayed-action fuse (FC2) of max. 4 A. In order to guarantee the protection function, install the trigger unit as the first element in the control power circuit.

ATTENTION
Measure circuit BT1 and BT2 (PTC sensor) must not come into contact with external voltage. This would destroy the trigger unit INT69 G and PTC sensors.

Function test of the trigger unit INT69 G
Before commissioning, after troubleshooting or making changes to the control power circuit, check the functionality of the trigger unit. Perform this check using a continuity tester or gauge.

Oil sump heater (accessories)
In order to avoid damage to the compressor, the compressor must be equipped with Faig.n o 1il 9sump heater.

ATTENTION The oil sump heater must generally be connected and operated!

Connexion: The oil sump heater must be connected via an auxiliary contact (or parallel wired auxiliary contact) of the compressor contactor to a seperate electric circuit.
Electrical data: 110 – 240 V – 1 – 50/60 Hz, 50 – 120 W, PTC-heater adjusting.

Selection and operation of compressors with frequency converters
For safe operation of the compressor, the frequency converter must be able to apply an overload of at least 160% of the compressor’s maximum current (I-max.) for at least 3 seconds.
When using frequency converters, the following things must also be observed:

1. The maximum permissible operating current of the compressor (I-max) (see type plate or technical data) must not be exceeded.
2. If abnormal vibrations occur in the system, the affected frequency ranges in the frequency converter must be blanked out accordingly.
3. The maximum output current of the frequency converter must be greater than the maximum current of the compressor (I-max).
4. Carry out all designs and installations in accordance with the local safety regulations and common rules (e.g. VDE) and regulations as well as in accordance with the specifications of the frequency converter manufacturer

The permissible frequency range can be found in the technical data chapter 8, p. 24.

f-min/f-max see chapter 8: Technical data: permissible frequency range

Commissioning

Preparations for start-up

INFO To protect the compressor against inadmissible operating conditions, high pressure and low pressure pressostats are mandatory on the installation side. The compressor has undergone trials in the factory and all functions have been tested. There are therefore no special running-in instructions.
Check the compressor for transport damage!

WARNING
When the compressor is not running, depending on ambient temperature and amount of refrigerant charge, it is possible that the pressure may rise and exceed permitted levels for the compres-sor. Adequate precautions must be taken to prevent this happening (e.g. using a cold storage medium, a receiver tank, a secondary refrigerant system, or pressure relief devices).

Pressure strength test
The compressor has been tested in the factory for pressure integrity. If however the entire system is to be subjected to a pressure integrity test, this should be carried out in accordance with EN 378-2 or a corresponding safety standard without the inclusion of the compressor.

Leak test

DANGER Risk of bursting!
The compressor must only be pressurised using nitrogen (N2). Never pressurise with oxygen or other gases!
The maximum permissible overpressure of the compressor must not be exceeded at any time during the testing process (see name plate data)! Do not mix any refrigerant with the nitrogen as this could cause the ignition limit to shift into the critical range. Carry out the leak test on the refrigerating plant in accordance with EN 378-2 or a corresponding safety standard, while always observing the maximum permissible overpressure for the compressor.

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.
• Open the suction and pressure line shut-off valves.
• Turn on the oil sump heater.
• Evacuate the suction and discharge pressure sides using the vacuum pump.
• At the end of the evacuation process, the vacuum should be < 1.5 mbar when the pump is switched off. Repeat this process as often as is required.

Refrigerant charge

CAUTION Wear personal protective clothing such as goggles and protective gloves! Make sure that the suction and pressure line shut-off valves are open.

INFO Depending upon design of the CO2 refrigerant filling bottle (with/without tubing) CO2 can be filled in liquid after weight or gaseously.
Use only high-dried CO2 quality (see chapter 3.1)!

• Filling the liquid refrigerant: It is recommended that the system first be filled at standstill with gas on the high-pressure side up to a system pressure of at least 5.2 bar (if it is filled below 5.2 bar with liquid, there is a risk of dry ice formation). Further filling according to system.
• To eliminate the possibility of dry ice formation when the system is operating (during and after the filling process), the shut-off point of the low-pressure switch should be set to a value of at least 5.2 bar.

WARNING Never exceed the max. permissible pressures while charging. Precautions must be taken in time.
A refrigerant supplement, which may become necessary after start-up, can be topped up in vapour form on the suction side.

ATTENTION

• Avoid overfilling the machine with refrigerant!
• Do not charge liquid refrigerant into the suction-side on the compressor.
• Do not mix additives with the oil and refrigerant.

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 hammer effects. If this is the case check the oil return!

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 CO2 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 condi-tions can occure, which may result in a permanent leak. Always check system for refrigerant loss after activation of pressure relief valve!
The decompression valves do not replace any pressure switches and the additional safety valves in the system. Pressure switches must always be installed in the system and designed or adjusted in accordance with EN 378-2 or appropriate safety standards.
Failure to observe can result in risk of injury from CO2 streaming out of the two decompression valves!

Avoid slugging

ATTENTION Slugging can result in damage to the compressor and cause refrigerant to leak.

To prevent slugging:

• The complete refrigeration system 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 superheat at the compressor input should be 15 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.
• Particularly in critical systems (e.g. several evaporator points), measures are recommended such as replacement of liquid traps, solenoid valve in the liquid line, etc.
  There should be no movement of coolant whatsoever while the compressor is at a standstill.

Filter dryer Gaseous CO2 has a significantly lower solubility in water than other refrigerants. At low temperatures it can therefore cause blocking of valves and filters due to ice or hydrate. For this reason we recom-mend the use of an adequately sized filter drier and a sight glass with a moisture indicator.

Connection of oil level regulator
The connection “O” is provided for installing an oil level regulator. A corresponding adapter must be obtained from the trade.

Maintenance

Preparation

WARNING
Before starting any work on the compressor:

• Switch off the compressor and secure it to prevent a restart.
• Relieve compressor of system pressure.
• Prevent air from infiltrating the system!

After maintenance has been performed:

• Connect safety switch.
• Evacuate compressor.
• Release switch lock.

Work to be carried out

In order to guarantee optimum operational reliability and service life of the compressor, we recommend carrying out servicing and inspection work at regular intervals:

Oil change:

• not mandatory for factory-produced series systems.
• for field installations or when operating near the application limit: for the first time after 100 to 200 operating hours, then approx. every 3 years or 10,000 – 12,000 operating hours. Dispose of used oil according to the regulations; observe national regulations.

Annual checks:
Oil level, leak tightness, running noises, pressures, temperatures, function of auxiliary devices such as oil sump heater, pressure switch.

Recommended spare parts/accessories
Available spare parts and accessories can be found on our compressor selection tool under vap.bock.de as well as at bockshop.bock.de.
Only use genuine Bock spare parts!

Lubricants
For operation with CO2 the BOCK lub E85 is necessary!

Decommissioning

Close the shut-off valves on the compressor. CO2 does not need to be recycled and can therefore be blown off into the environment. It is essential to ensure good ventilation or conduct the CO2 into the outdoors to avoid danger of suffocation. When releasing CO2, avoid a fast drop in pressure to prevent oil from exiting with it. If the compressor is unpressurized, remove the piping on the pressure- and suction-side (e.g. dismantling of the shut-off valve, etc.) and remove the compressor using an appropriate hoist. Dispose of the oil inside in accordance with the applicable national regulations. When decommissioning the compressor (eg. for service or replacement of the compressor) larger amounts of CO2 in the oil can be set free. If the decompression of the compressor is not sufficient enough, closed shut-off valves may lead to intolerable excessive pressure. For this reason the suction side (LP) and the high pressure side (HP) of the compressor have to be secured by decompression valves.
