Fig. 4 3.3 Operating limits 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: 140°C - M ax. permissible switching frequency: 8x /h - A minimum running time of 3 min. - Page 9 3 | Areas of application ATTENTION! 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.

Page 20: Commissioning
6| Commissioning 6.1 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! 6.2 Pressure strength test The compressor has been tested in the factory for pressure integrity. -
Page 21: Refrigerant Charge
6 | Commissioning 6.5 Refrigerant charge CAUTION! Wear personal protective clothing such as goggles and protective gloves! Make sure that the suction and discharge line 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. -
Page 22: Maintenance
Annual checks: Oil level, tightness, running noise, pressures, temperatures, function of auxiliary devices such as a oil sump heater, pressure switch. 7.3 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! -
