4 Safety The Bock refrigerating compressors named in the title are intended for installation in machines (within the EU according to EU directive 98/37/EC Machinery Directive, 97/23/EC Pressure Equipment Directive and 73/23/EC Low Voltage Directive). Initial commissioning is only allowed when the compressor has been installed according to these instructions and the whole machine in which it is integrated has been tested and accepted according to the statutory regulations. Bock refrigerating compressors have been designed to state-of-the-art engineering. Safety for the user is given particular priority during the design stage. However, it is always possible for the refrigerating machine and operation thereof to pose unavoidable residual risks. This is why these instructions must be observed carefully by every person working at the compressor. Work on the compressor may only be carried out by persons whose technical training, skills and experience together with their knowledge of pertinent regulations and documentation means that they are capable of assessing the work to be carried out and detecting any possible dangers (trained staff as per DIN 31000) SAFETY INSTUCTIONS Caution! efrigerating compressors are pressurised machines and therefore require particularly careful and meticulous handling. Only quali ed staff are allowed to handle refrigerating compressors. National safety regulations, accident prevention regulations, technical rules and other speci cations (incl. EN 378 etc.) must be observed The compressor may only be operated in refrigerating systems, and only with coolants approved for this compressor by Bock. The maximum tolerable operating overpressure may not be exceeded (not even for test purposes). Pressure switches are required to safeguard the machine from excess pressures. New compressors are provided with an inert gas lling in the factory (approx. 3 bar nitrogen) The pressure in the compressor must be relieved before connecting up the refrigerating system. Before starting the compressor, check for any signs of transport damage. Before starting up, check that all components mounted by the user have been properly tted and are connected pressure-tight with the compressor (e.g. pipelines, bungs, union nuts, replaced parts, etc.) Before starting up, evacuate the refrigerating machine carefully with the compressor and then ll with coolant. Before starting the compressor, open the discharge shut-off valve and suction shut-off valve. Do not start the compressor in a vacuum. Only operate the compressor when the whole system has been lled. Surface temperatures of more than 100 C are possible on the pressure side respectively below 0 C on the suction side, depending on operating conditions.

Installation instructions Transport eyelet General Only lift the compressor at the transport eyelet. The hoisting gear must be suitable for the compressor weight. When erecting the compressor in a closed room, suf cient ventilation of the machine room air must be guaranteed. Do not operate the compressor in a corrosive atmosphere, dust, steam or ammable environment. Allow suf cient space for performing maintenance work. The compressor must be erected horizontally on anti-vibration pads or if necessary rigidly. Avoid any distortion in the compressor housing. Always consult the manufacturer before mounting the compressor in a slanting position! Direct erection on bundle pipe condensers only with anti-vibration pads. isk of vibration cracks and breakage with rigid installation! In addition, we recommend the installation of pipeline vibration compensators. Pipe connections / pipes Caution! Compressor is pressurised. Leave the inert gas lling in the compressor until initial commissioning. The shut-off valves should remain closed until evacuated. The pipe connections are suitable for all pipes of normal metric and inch dimensions. The solder connections of the shut-off valves are to be removed from the shut-off valves when soldering the pipes. Pipes and machine components should always be clean and dry on the inside, and free of cinders, metal chips, rust and phosphate coats. In addition, all parts to be tted to the compressor and to the whole machine must be delivered sealed air-tight

9 Pipe installation Ensure there is provision for proper oil re ux Pipes and non-return valves must be dimensioned according to the operating points. Pressure losses must be kept to a minimum. Fix the pipes with fastening clips with rubber sleeves. Provide suitable vibration compensators for the pipes, ensuring they are mounted in the correct position. Prevent any vibration in the pipes, as these can cause cracks or breaks (caution! isk of coolant leaks). Check the whole machine regularly. Shut-off valves i Warning! Both shut-off valves - the suction and the discharge shut-off valve - must be opened before starting the compressor! Before opening or closing the shut-off valve, turn the valve spindle seal approx. 1 4 of a turn counter-clockwise. After activating the shut-off valve, tighten the valve spindle seal again clockwise.

10 Electrical connection General instructions The electrical connection of the motor is to be completed according to the main line circuit diagram (on the inside of the terminal box). When connecting up the compressor, always comply with the local electricity regulations (VDE 0100 for Germany). Use suitable screwed cable glands with protection class IP 54 for the cable leadthroughs at the terminal box. Use strain relief elements. Avoid any chafe marks on the cables. Motor contactors (see table), feed lines and fuses are to be rated according to the maximum operating current (see compressor nameplate). Compare the details for voltage and frequency on the nameplate with the details for the electricity mains supply. The motor may only be connected up when these details correspond. Standard motor, designed for direct or part winding start Features: Designation on the nameplate: Y / YY Designation on the yellow label on the terminal box (see gur): Compressors marked in this way are suitable for direct or part winding start. The motor winding is divided into two parts: part winding 1 = 60% and part winding 2 = 40%. This winding division reduces the start-up current during a part winding start to approx. 65% of the value for a direct start. i Mechanical start unloader with bypass solenoid is not required In the factory, the motor is switched for direct starting (YY) (see photo). For part winding start Y/YY, remove the bridges and connect the motor feed cable according to the circuit diagram. right wrong part winding 2 = 40% part winding 1 = 60% Terminal box with bridges inserted for direct start WANING! Failure to comply results in reversed elds of rotation and can cause motor damage. After the motor has started up with part winding 1, part winding 2 must be switched on after max. 1 second delay. Failure to comply can be detrimental to the service life of the motor

11 Main line wiring diagram for part winding start with standard motor CAUTION! Ensure that power is supplied via K1 to winding 1 (60%) (1U1 / 1V1 / 1W1) and via K2 to winding 2 (40%) (2U1 / 2V1 / 2W1). The motor contactors (K1/K2) are each to be rated for approx. 70% of the max. operating current. 1-2 Connections for PTC sensor K1 Mains contactor (part winding 1) 1 PTC sensor motor winding K2 Mains contactor (part winding 2) 2 Heat protection thermostat (PTC sensor) K1T Delay relay max. 1s F1 2 motor safety switches (60%:40% of I A total) A1 Trigger unit MP10 F2 Fuse control power circuit Q1 Main switch F3 Safety chain (high/low pressure monitoring) S1 Switch control voltage F4 Oil differential pressure controller M1 Compressor motor B1 Enabling switch (thermostat) Special motor, version for direct or star delta starting Example for motor 230 V / 400 V Y Features: Designation on the nameplate: / Y Designation on the yellow label on the terminal box ( gur).

13 Electronic trigger MP 10 The compressor motor is equipped with posistor temperature sensors (PTC) which are wired to the electronic trigger MP 10 in the terminal box. The stand-by mode is indicated by the light diode H3 (green) when mains voltage is applied. In the event of overtemperature in the motor winding, the device switches the compressor off and signal lamp H1 lights up red. In addition, the hot gas side of the compressor can be protected from overheating by heat protection thermostats (accessories). i When the device has triggered, this indicates an overload or intolerable operating conditions. Ascertain and eliminate the cause. The device has a reclosure preventing feature. After eliminating the fault, the device is quit by interrupting the mains power with the external alarm reset switch S1 (see main-line wiring diagram). The reclosure preventing feature is unlocked and LEDs H1 or H2 go off again. Connection of the electronic trigger MP 10 The electrical connection of MP 10 is to be completed according to the circuit diagram. The trigger is to be protected with a fuse (F) of max. 4 A, slow-acting. To guarantee the protection function, the electronic trigger is mounted as rst element in the control power circuit. Connections temperature monitoring: motor winding: terminals 1-2 hot gas side: terminals 3-4 WANING! Terminals 1-6 on the electronic trigger MP 10 and terminals PTC 1 and PTC 2 on the compressor terminal board (see diagram) may not come into contact with mains voltage. This would destroy the electronic trigger and the PTC sensors.

15 Oil sump heating When the compressor is at a standstill, coolant diffuses into the lubricating oil of the compressor housing, depending on pressure and ambient temperature. This reduces the lubricating capacity of the oil. When the compressor starts up, the coolant 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. In order to avoid damage to the compressor, the compressor is equipped with an oil sump heating as a standard feature. The oil sump heating should always be connected up and operated. Operation: The oil sump heating operates when the compressor is at a standstill. When the compressor starts up, the oil sump heating switches off again automatically. Connection: The oil sump heating must be connected via an auxiliary contact (or parallel wired auxiliary contact) of the compressor contactor to a separate electric circuit. El. data: 230 V ~ / 80 W WANING! The oil sump heating must not be connected to the electrical circuit of the safety control chain. Initial commissioning The compressor has undergone trials in the factory and all functions have been tested. There are therefore no special running-in instructions. i Before starting up, check the compressor for any signs of transport damage! To protect the compressor from intolerable operating conditions, high- and lowpressure pressostats. Comply with the accident prevention regulations! Leak test, evacuation Check the refrigerating system for leaks without including the compressor (preferably with dried N2) In the following evacuation process, evacuate the machine rst, then include the compressor as follows: - elease the pressure in the compressor using the suction and pressure shut-off valves at service connection 2. - Open the suction and discharge shut-off valves - Evacuate the suction and high-pressure wide with the vacuum pump. - Vacuum 1.5 mbar while the pump is switched off. - epeat the procedure several times. The refrigerating machine is then dry and tight when the pressure increase in the refrigerating system is < 0.5 mbar/24h. WANING! Do not start the compressor in vacuum. Do not apply voltage, not even for test purpose (may only run after lling with coolant). The spark-over and leakage current distances of the terminal board connection bolts are reduced in a vacuum, this can cause damage to the winding and to the terminal board. Filling with coolant i Caution! Wear personal safety gear! Check that the compressor suction and discharge shut-off valves are open. With the compressor switched off, ll the liquid coolant directly into the condenser or receiver, breaking the vacuum

16 i Start the compressor. If the coolant 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. Avoid over lling the machine with coolant. To avoid shifts in concentration, zeotropic coolant blends (e.g. 407C) must always only be lled into the refrigerating system in liquid form WANING! Do not ll liquid coolant into the suction shut-off valve on the compressor. Do not mix additives with the oil and coolant. Operation check After initial commissioning has been completed, check that the machine complies with the tolerable operating conditions. Liquid shocks WANING! Liquid shocks can cause damage to the compressor and leakage of coolant. To avoid liquid shocks, the following points should be observed: The whole plant must be properly designed. All components must be rated to be compatible with each other with regard to output (particularly evaporator and expansion valve). Suction gas overheating at the evaporator output should be min K (check setting of the expansion valve). The machine 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 in the liquid line, etc. Coolant should not move in the compressor when the machine is at a standstill. Lubrication / oil check Check oil pressure using a pressure gauge when starting up via the gauge connection at the oil pump. Oil differential pressure approx bar (depending on operating conditions, coolant and lubricant). After reaching equilibrium (constant operating conditions), check the oil level in the compressor. It should be visible in the lower section of the sight glass (see diagram). Automatic monitoring by oil differential pressure switch. Check the functions of the oil differential pressure switch when the machine starts up. i Normal oil level When the unit causes the system to close down, proceed with fault analysis. Comply with the instructions on the cover of the switch. WANING! If larger quantities of oil have to be topped up, there is a risk of liquid shocks. In this case, the oil return has to be checked

17 Connection of the oil level controller Oil level controlling systems have proven useful in compound systems with several compressors. Connection O is provided for tting an oil level controller (see dimensioned drawing). All customary oil level controllers make AC&, ESK and the electronic controller system TAXOIL S1A21 by SPOLAN can be connected up directly without needing an adapter (see diagram).

Comply with the safety instructions on page 4! 47,6 Before any work is carried out on the compressor, switch the machine off and secure it to prevent it being switched on again. elieve the pressure in the system using an extraction device. Do not release coolant into the atmosphere! After maintenance has been completed, check the safety switch and check functions. Evacuate the compressor. emove the switching-on safeguard. Service intervals The compressor is to be kept in a clean, orderly condition by suitable care. In order to guarantee optimum operating safety and service life of the compressor, we recommend that you carry out the following servicing and checks at regular intervals: Oil change including cleaning the oil intake lter: after operating hours, then once per year. Dispose of used oil properly, comply with national regulations. Drain oil through plug F (see dimensioned drawing/connections) Function checks: leaks, running noises, pressures, temperatures, proper functioning of all additional equipment such as capacity regulators, oil sump heating, pressure switch: once per year. 124 o ecommended alternatives for H-CFCs (e.g. 22) FUCHS eniso SP 46 MOBIL SHC 425 SUNOIL Suniso 4 GS SHELL Clavus SD TEXAKO Capella WF 46 SUNOIL Suniso 3 GS for uorocarbons (e.g. 134a, 404A, 407C) FUCHS eniso Triton SE 55 FUCHS SEZ 32 MOBIL Arctic EAL 46 ICI Emkarate L 46 S SHELL Clavus
