2.3 Checking the Vacuum Fit the resin feed system to the resin and sample chambers, as shown in the diagram for section 3.1.3, ensuring that the O‐rings, shown in section 3.1.1, are in place contacting the top of the glass lid (16). Check visually that the O‐rings on the sample chamber (1) are in place and that the resin chamber (2) is sitting squarely under the glass lid (16) on its spring loaded base. Ensure that the resin and sample chamber valves (10, 12) and the resin and sample chamber vents (11, 13) are closed. Switch on the machine using the mains switch at the side by the electrical inlet. The pump will start and the mains indicator light (8) on the pirani gauge (9) will glow green. The pirani gauge (9) will progressively reduce in reading to the ultimate vacuum achieved by the pump over a period of up to half a minute. This should be in the region 10 ‐2 to 5x10 ‐2 mbar. Slowly open the sample chamber valve (12) ‐ the sample chamber (1) will start to pump down. On a new machine the vacuum will gradually build over a period which may be as long as half an hour, depending on water vapour etc., which has accumulated in transit (after this first pump down the sample chamber should evacuate in under five minutes). If the vacuum fails to start building, ensure that all O‐rings are sitting on clean surfaces. Repeat this check after opening the resin chamber valve (10), so that both chambers are evacuated. In both cases the ultimate vacuum reach will depend on atmospheric and other conditions but should be in the region of 5x10 ‐2 mbar to 10 ‐1 mbar. 2.4 Health & Safety When operating this unit the operator must be aware of the risks involved when working with resins and vacuum pressure. a) The unit is operated under sufficient vacuum pressure to accelerate the exothermic reaction in the resin when out gassing. Care must be taken to slowly control the rate of expansion of the resin bubbling up or effervescing to retain it inside the mixing vessel. This is done by manually adjusting rate of air removal via the vacuum/air control valves. b) The vacuum pump exhaust port emits oil vapour and must be vented correctly through a suitable oil mist filter (see separate vacuum pump manual if supplied with the machine) or to the facility exhaust system to prevent oil mist in the working area. c) The system is not sensitive to vibration and can be installed on a standard bench which will support the weight (74kg).

d) The system should be situated away from areas of dust or particle contamination as this may affect the quality of the impregnation if airborne particulates become trapped in the resin layer. e) No special lighting is required for the system and the machine may be operated from 200 lux or above environment with no flicker or glare. 2.5 Machine Noise Levels The IU30 series of machines in normal operation run at a noise level below 70dB (A). The main noise from the unit occurs through the oil pump and motor which is below 70dB (A). The IU30 unit was tested using a calibrated ISOTECH SLM‐52N (serial number 090514361) sound level gauge (technical data included in the technical file) over a one hour period and averaged below 70dB (A). Background levels were recorded at 58dB (A) +/‐2dB before and after the tests. The sound meter was placed 1m from the unit and facing the unit directly at a height 1.6m from the floor.
