Areas of application

Refrigerants

• HFKW / HFC: R134a, R404A/R507, R407C
• (H)FCKW / (H)CFC: R22

Oil charge

The compressors are filled at the factory with the following oil type:

• for R134a, R404A/R507, R407C: BOCK lub E55
• for R22: BOCK lub A46

Compressors with ester oil charge (BOCK lub E55) are marked with an X in the type designation (e.g. HGX34e/380-4).

INFO: For refilling, we recommend the above oil types: see chapter 7.4

ATTENTION

• 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 invormation given there.

• Permissible ambient temperature (-20°C) – (+60°C)
• Max. permissible discharge end temperature 140°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 supplementary cooling:

• Use only oils with high thermal stability.
• Avoid continuous operation near the threshold.

For operation with capacity regulator:

• Continuous operation, when the capacity regulator is activated, 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 sufficient oil is transported back to the compressor.

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 subject of frequency converters, see chapter 5.9,)

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!

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 transport

• 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 loadbearing capacity.
• Single compressor preferably on vibration damper.
• Duplex and parallel circuits always rigid.
• Sun protection: If the compressor is set up outdoors, it has to be protected from direct sunlight.

Pipe connections

_ ATTENTION: _Damage possible.

• Do not solder as long as the compressor is under pressure.
• 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).
• 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: 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

Opening the shut-off valve

• Spindle: turn to the left (counter-clockwise) as far as it will go.
  • —> Shut-off valve completely opened / service connection closed.

Opening the service connection

• Spindle: Turn ½ – 1 turn to the right clockwise.
  • —> Service connection opened / shut-off valve opened.

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 devices and switching or monitoring units must be fitted in accordance with the local safety regulations and established specifications (e.g. VDE) as well as with the manufacturer’s information.
• Motor protection switches are required! Motor contactors, feed lines, fuses and motor protection switches must be rated on the basis of the maximum working current (see name plate).
• For motor protection use a current-dependent and time-delayed overload protection device for monitoring all three phases. Set the overload protection device so that it must be actuated within 2 hours, if there is 1.2 times the max. working current.

Connection of the driving motor

• The compressor is designed with a motor for star-delta circuits.

Designation on the name plate

Star-delta start-up is only possible on 230 V voltage supply. Example:

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

Circuit diagramm for direct start 230 V Δ / 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.

Relay position INT69 G

| Gauge state| Relay position
---|---|---
1.| Deactivated state| 11-12
2.| INT69 G switch-on| 11-14
3.| Remove PTC connector| 11-12
4.| Insert PTC connector| 11-12
5.| Reset after mains on| 11-14

Start unloader

• To avoid current peaks during the starting phase we recommend using the Bock Bock-ESS soft starting device (Electronic Soft Start). Refer to “Accessories” for further information.

Oil sump heater

When the compressor is at a standstill, refrigerant diffuses into the lubricating oil of the compressors housing, depending on pressure and ambient temperature. This reduces the lubricating capacity of the oil. When the compressor starts up, the refrigerant contained in the oil evaporates out through the reduction in pressure. The consequences can be foaming and migration of the oil, causing oil shocks under certain circumstances.

Operation: The oil sump heater operates when the compressor is at a standstill. When the compressor starts up, the oil sump heater switches off again automatically.

Connection

• The oil sump heater must be connected via an auxiliary contact (or parallel wired auxiliary contact) of the compressor contactor to a separate electric circuit. El. data: 50 – 120 W, 110 – 240 V AC

ATTENTION: Connection to the current path of the safety control chain is not permitted.

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 140% 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.

f-min/f-max see chapter: Technical data: adjustable 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!

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.
• 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.
• With the compressor switched off, add the liquid refrigerant directly to the condenser or receiver, breaking the vacuum.
• If the refrigerant needs topping up after starting the compressor, it can be topped up in vapour form on the suction side, or, taking suitable precautions, also in liquid form at the inlet to the evaporator.

ATTENTION

• Avoid overfilling the system with refrigerant!
• To avoid shifts in concentration, zeotropic refrigerant blends (e.g. R407C) must always only be filled into the refrigerating plant in liquid form.
• Do not pour liquid coolant through the suction line valve on the compressor.
• It is not permissible to 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 all functioning properly.
• Switch on the compressor and allow to run for a minimum of 10 min.
• Check the oil level by: The oil must be visible in the sightglass.

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!

Avoiding slugging

ATTENTION: Slugging can damage 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 min. 7 – 10 K. (check the setting of the expansion valve).
• 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.

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.

Spare parts recommendation/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 / oil

The oil type filled as standard in the factory is marked on the name plate, and this should always be used, even in the case of maintenance units. Alternative oil types can vary significantly in quality due to additives or inferior raw materials by the manufacturer. Validation within the compressors entire operating limits can not be guaranteed, if such alternative oil types are used. It is for this reason, that we only recommend the use of oil from Bock! Bock assumes no liability for any damage arising from alternative oil types.

Decommissioning

Close the shut-off valves on the compressor. Drain the refrigerant (it must not be discharged into the environment) and dispose of it according to the regulations. When the compressor is depressurised, undo the fastening screws of the shut-off valves. Remove the compressor using an appropriate hoist. Dispose of the oil inside in accordance with the applicable national regulations.
