14 2 Included with the Unit as Supplied The Contamination Test Unit CTU comes packed and partially factory-assembled. Before commissioning the CTU, check the contents of the consignment to make sure everything is present. The CTU comes with the following: No. Qty Description 1 1 Contamination Test Unit CTU 2xxx Series 2 1 Waste air outlet kit, consisting of: 1x quick connect cover, 1x hose nozzle, 2x gaskets, various hardware items 3 1 Four-sided hollow socket key, 6 mm - 1 Spray gun including connector hose - 1 Accessories for 3-fold membran retainer: 2x Support ring, 3x Support strainer - 1 Drain tray - 1 Operating and Maintenance Instructions HYDAC Filtertechnik GmbH en Page 14

15 3 Designated Use of the CTU The CTU is a specially designed test stand for analyzing the surface cleanliness of components. These components undergo rinsing in a defined clean environment using an analysis fluid, which also has a defined cleanliness. The particle-laden fluid is filtered through a prepared analysis membrane and then subjected to analysis. The resulting findings provide information on the type, size and mass of contamination. Knowing what type of contamination is involved enables measurements to be taken to prevent it (improved filtration, transportation, storage, etc.). 3.1 Designated Media The CTU may only be used with: rinsing fluids which are compatible with the sealing and gasket materials used in the unit rinsing fluids which are not combustible rinsing fluids which don t require explosion-proofing (class AIII) (flashpoint 60 C, lower explosion limit > 0.6 % by vol.) Don t use water as rinsing fluids. That will get to do damage the system! Generally speaking, we advise you to contact us if you have any reservations concerning the rinsing fluid.

17 3.4 Operating Console Shut-off Valve, Rinsing Fluid Setting of: Vacuum Return Line Setting of: Pressure Rinsing Fluid Vacuum shut-off valve 3-fold Membrane retainer Compressed air shut-off Compressed air inlet 3.5 Function After the CTU is filled the rinsing fluid is located in reservoir B1. The component to undergo analysis is located in the analysis chamber (4). As soon as the operating mode is changed from Stand-by to Operation, reservoir B1 is pressurized. After the desired quantity of rinsing fluid is filled and contamination testing is started via the text display, actuating the spray gun (7) causes the rinsing fluid to be conveyed from reservoir B1 to the analysis chamber via the rinsing fluid micronic filter (22). The operator has to make sure that the surfaces of the component to be analyzed are flushed. The contamination-particle-loaded rinsing fluid is sucked via vacuum action through the analysis membrane (11) and flows into reservoir B2. The vacuum is created by a vacuum generator (21) employing the Venturi principle. The fill level in reservoirs B1 and B2 is continuously monitored via level sensors (12, 13). When the lower fill level is reached in reservoir B1, switchover automatically takes place between reservoir B1 and reservoir B2 so that the rinsing fluid is conveyed from reservoir B2 into reservoir B1 during further processing. The quantity of rinsing fluid is determined by a meter (23). The contamination test is automatically stopped when the preselected quantity has been conveyed. The analysis membrane can now be taken out and analyzed. HYDAC Filtertechnik GmbH en Page 17

18 3.6 Hydraulic Schematic 3.7 Clean-Room Conditions in the Analysis Chamber The filter hood contains the clean-air module for supplying the analysis chamber with filtered air. An air curtain and overpressure are created in the analysis chamber via the clean-air module, the overpressure preventing particles from entering into the analysis chamber from the environment. The filter hood also contains the extract ventilation system. This is used to extract the air of the analysis chamber in the front area of the CTU and convey it to the waste air ducts.

The CTU is to be unplugged from the power supply during any inspection or maintenance work. The CTU is to be secured as follows when performing any maintenance, servicing, inspection or repair work. Switch off the CTU as described in section 6.11 Power-down and via the main switch. The pressure gauges show the pressure and vacuum during operation, however not the current reservoir pressure. Only by powering down the CTU are the pressure vessels air-bled. Pull the power plug. Affix a warning sign so as to prevent the unit from being inadvertently switched back on. 8.1 Inspection Work Inspections have to be conducted at regular intervals. We recommend that the following be performed on a weekly basis: Perform a visual check of the hoses and piping for leaking and brittleness. Conduct a visual check of the electric equipment for damage to lines, the plug, sensors or cabling and the devices in the switch cabinet. Check screwed and plug fittings to ensure that they are sufficiently tight/secured. Check all the signal and display lamps. HYDAC Filtertechnik GmbH en Page 36

37 Check the function of the analysis chamber lighting. Check the function of the shut-off valves. 8.2 Maintenance Work The maintenance and servicing to be performed periodically is described here. The CTU s serviceability, operational reliability and life substantially depend on performing maintenance and servicing work regularly and carefully. For further maintenance information, refer to the documentation provided by the supplier. see Every 100 hours of operation or weekly Every 6000 hours of operation or yearly As needed or after at the latest Hoses years Rinsing fluid micronic filter year Return line filter year Replace clean room prefilter mat year Rinsing fluid micronic filter years Drain in-between tray X Calibrate the flow rate meter X Clean the analysis chamber X Change the analysis fluid month Hoses The hoses used in the CTU are specifically designed and rated for use with the rinsing fluids described in these operating instructions.

41 8.2.3 Replacing the Clean-Room Prefilter Mat A prefilter and main filter are used in the clean-room module of the CTU. The prefilter mat [2] has to be changed regularly. No generally binding maintenance intervals can be given as every situation is different. The intervals have to be determined by experience. We recommend replacing the prefilter every 6 months, or every year at the latest. Remove the hexagon socket head mounting screws of the filter hood cover [1]. Remove the filter hood cover [1]. The prefilter mat is now exposed and can be removed. Insert the new prefilter mat [2]. Replace the filter hood cover [1] and screw it tight Replacing the Clean-Room Main Filter The main filter may not require maintenance for virtually years on end providing the prefilter mat is regularly changed as needed. However, we recommend that the main filter be replaced every 2 years at minimum so as to ensure trouble-free operation of the CTU. The main filter of the analysis chamber can be replaced without having to disassemble the filter assembly as follows: HYDAC Filtertechnik GmbH en Page 41

44 8.2.5 Draining the In-between Tray When the air is sucked out of the analysis chamber during contamination testing sometimes the rinsing fluid is extracted at the same time. It is collected underneath the analysis chamber in the in-between tray. Depending on usage, it has to be emptied at least once a week. There is a drain ball valve underneath the drain tray for this purpose. Drain ball valve Calibration of the Rinsing Fluid Meter The meter should be checked/inspected once a year. This can be done by simply gauging the flow rate of the meter in liters: Obtain a measuring receptacle able to hold 5 l. Start the contamination test with a rinsing volume of 5 l. Fill the measuring receptacle with a spray gun. After the contamination test completes automatically, read the quantity remaining in the measuring receptacle. A measured deviation of +/-2% should not be exceeded/fallen short of. If the deviation is larger than 2% the meter has to be sent in for adjustment in the factory Cleaning the Analysis Chamber The analysis chamber should be manually cleaned at least once a week. We recommend using a clean microfiber cloth for this purpose. HYDAC Filtertechnik GmbH en Page 44

45 8.2.8 Changing the Analysis Fluid No generally binding intervals can be given for when the fluid has to be changed as every situation is different. The intervals have to be determined by experience.
