WARNING This Symbol Represents a to Ensure Safe and Correct Operation. Failure to observe this caution could result in personal injuries or damages on the assets only. Please follow the instructions indicated by this symbol. Useful tips for operations. For your safety Use this filter housing below the design pressure. Otherwise, it may cause leakage or breakage. Never use gases with the filter housing. If it should be broken, there may cause damages to human bodies and WARNING properties. If you open or close the valves in an abrupt manner, the filter housing may be damaged due to pulsations of the line pressure. Besides if you apply a shock, excessive flow rate or back flow to the filter housing, it may cause damages to the cartridge or housing. Never use the filter housing in such improper ways. Never use the housing filter for corrosive fluids. In addition check the fluid in advance to see if it is appropriate to the filter housing of 1BS-T/1BS-TW. To prevent electrostatic accumulation of electricity, Use a ground wire. When you use the filter housing for high-temperature fluid, its surface will become hot. Pay enough attention when you handle the housing. When you replace a cartridge with another, release the pressure in the filter housing. Especially when you use high-temperature fluid, it may blow out. Deterioration or destruction of gaskets and others may cause the fluid used to blow out. Inspect them regularly and replace them if deterioration or destruction is detected. For the maximum allowable working pressure, working temperature, flow-rate and others, observe the conditions specified when the filter housing was selected. 1
When you detect anything wrong with the filter housing body or gaskets and others (e.g. damages), stop using it immediately. Attention to galling or seizure of treaded portions It is said that in general stainless steel is likely to have galling or seizure because its thermal conductivity is lower than ordinary steel and the thread surface develops larger heat and expands more. Galling or seizure can be reduced by taking appropriate actions but in fact existing technologies cannot eliminate galling or seizure as well as contamination by foreign matters completely. For the threaded portions of this device (center rod and cap nut, and center rod and cover), stainless steel is used. Therefore, please use the device in an appropriate manner while paying attention to the items described below in order to prevent galling or seizure. In order to prevent galling of stainless steel components, surface coating or appropriate lubricant should be used to reduce friction and to improve thermal conductivity. Neither special disposition nor treatment is applied for the threaded portions of this device. Please use the lubricant optimal to your working conditions. When you remove the cap nut, take the most care not to let the threaded portion contaminated by foreign matters. When you install it, fasten it with the specified torque at maximum. In case you have not removed the cartridge for a long time, the threaded portions may be solidified. In that case, check the threaded portions of the center rod, cap nut and cover if anything sticks to them after the components are removed. If anything remains, take it away before reassembling the device. When you assemble the threaded portions, first turn them a few times manually to verify there is no galling. Then, use the tools to fasten them. If leakage of the fluid used occurs to the sealing portions of the shell gasket or the nut gasket, fasten the cap nut with the specified torque at maximum. Then, if leakage cannot be stopped, the gaskets may be deteriorated, damaged or deformed. So, please replace them by new ones and fasten them again. If you forcibly fasten the threaded portions, it may cause galling. So, never fasten them with force. Please understand we do not include galling or seizure of the threaded portions of this device in our guarantee. 2

Installation and Piping 1. Follow the arrow marks on the head to connect pipes. 2. Place the filter housing upright on the cover. 3. Fix the filter housing by using the pipes at the inlet and the outlet. There is no mounting seat for the fixtures. See the figure below for fixing the housing. Vent Inlet Outlet Example of piping The filter housing usually does not carry a cartridge when it is supplied. Check if it has a cartridge or not before using it. Check if the shell gasket and nut gasket have been installed properly. Install valves before the inlet and after the outlet. In addition, install the manometer to measure pressure loss (differential pressure). 4.Because a cartridge needs to be replaced, secure a sufficient space for replacement where you install the filter housing. To prevent electrostatic accumulation of electricity, Use a ground wire. Do not connect the wrong pipes to the inlet and the outlet. If you do so, you cannot filter the fluid properly. Do not forcibly pull or bend the nozzle at the inlet or the outlet of the filter housing in order to adapt it to the piping at site. If you do so, you will damage the housing. Flushing and Cleaning 1.Clean the components before assemble a cartridge to the housing. 2. For cleaning use the fluid that is compatible to the fluid that is subject to filtration. 3. If you clean (flush) the filter housing with the components in place after piping by running a compatible fluid, you should keep it running 30 minutes or longer. 4. After cleaning is finished, disassemble the components before assembling a cartridge. For the procedure of disassembling the components, refer to the section describing the procedure to remove a cartridge. 5
How to assemble a cartidge 1.Confirm that the center rod has been screwed into the head surely without looseness. Assemble a new cartridge to the center rod. When you assemble the guide, you should make adjustments that the guide end comes approx. 30mm below the center rod end. Insert the protruding poring in the center of the cover into a cartridge and check if the cartridge tilts or gets loose. When you assemble a 10" of 3M TM Micro-Wind TM D Series filter cartridge to 1BS2-T/1BS2-TW, put a spacer between them. A spacer is not required for other filter cartridges. In case of 10" 3M TM Micro-Wind TM D Series filter cartridge make adjustments that the guide end comes approx. 30mm below the center rod end and the guide comes between the cartridges. In case of 20"of 3M TM Micro-Wind TM D Series filter cartridge, make similar adjustments for 10" to position the guide between the cartridges. (See the figures below.) 1BS1-T/1BS1-TW Guide 1BS2-T/1BS2-TW 2. Assemble the shell gaskets and nut gaskets to the gasket grooves of the head and the cover. Inspect the gaskets before assembling and if it has deterioration or damages, replace them by new ones. In addition, check if the filter housing body has anything abnormal. 3. Assemble the shell (this applied only to 1BS-T type). 4. Hold the cover firmly and insert it from the bottom of the head. 5. Screw the cap nut and tighten it. 6. Assemble the drain plug and tighten it. Make sure that the shell is fitted in the head groove and the cover groove. (For 1BS-TW type, the shell is welled to the cover.) When you fasten the cap nut, fix the projection on the cover bottom with the wrench. The appropriate torque for fastening the cap nut is 27 to 32N-m. The drain plug and vent plug are covered with sealing tape. If the tape is peeled off, cover them with new tape. 6

Deterioration or damages of gaskets may cause the fluid used to blow out. If the cap nut is not fastened appropriately, the fluid used may blow out. In addition, it may cause the center rod and cap nut had the threaded portion to suffer from galling. 7
Filtration process 1.Open the inlet to fill the filter housing with the fluid gradually. Make sure that the shell gasket and nut gasket are properly fitted. 2. Purge the air in the filter housing from the vent. 3. When the fluid comes out from the vent, close the inlet and tighten the vent plug. 4. Then open the inlet to pressurize the filter housing up to the working pressure. Make sure that the shell gasket and nut gasket do not have leakage. 5. If you find any leakage of the fluid, close the inlet and loosen the vent plug to depressurize the filter housing. 6. Tighten the cap nut. 7. Open the inlet again to pressurize the filter housing and check if the fluid is leaking. 8. When you find no leakage, open fully the inlet and the outlet for filtration. If you pressurize the filter housing up to the working pressure all at once, the fluid may blow out form the point where the fluid is leaking. Loosen the vent plug slowly not to let the fluid blow out. How to remove a cartridge 1. Close the inlet and the outlet to stop running of the fluid in the filter housing. 2. Loosen the vent plug to depressurize the filter housing gradually. 3. Loosen the drain plug to let out the fluid in the filter housing. 4. Loosen the cap nut and remove it 5. Remove the cover from the shell. 6. Pull out the used cartridge from the center rod. When you loosen the cap nut, you can remove the components from the head. So, hold the cover firmly not to let the components drop. Deal with the shell most carefully no to let its end have scratches. Clean up the components. Use a cleaning fluid compatible to the fluid for filtration. 8
