2 Feature (Effortless replacement of elements) (one element including type) How to remove an element. fter stopping the operation, close the valve in the order of inlet and outlet. 2. Open the air release valve to let the internal pressure of a filter be zero, and open the drain valve and liquid discharging valve to let out the internal fluid completely.. fter pulling the pin for confirming the tightening position, loosen the tightening nut, and then remove the T-bracket from the latch. (It is convenient to use a wrench commercially available with the nominal size 7.) How to attach an element. Pull a new element by the cloth handle toward the center, and put it inside the basket, folding the edge of an element. Further, push the edge of an element to the bottom plate's flange surface of the basket thoroughly. 2. Grasp the handle and put the basket in the case Note) Set the handle avoiding attaching it to the notch (guide groove) of the case. 4. Remove the cover upward by turning it counterclockwise Set the O-ring to the case. Replace the O-ring with a new one if it is expanded. (Refer to page 784, Seal list, Part nos.) 4. djust the pins (two locations) to the guide slit of the case inside the cover, and push them thoroughly and turning clockwise Using the handle, remove the basket vertically. Inspect a gasket in the case, and replace it with a new one if it is expanded. (Refer to page 784, Seal list, Part nos.) 6. handle made of cloth is attached to the element so that elements can be pulled out of the basket by fingers or using sticks, pulling them to the center Install the V-band in the edge of the cover and case correctly. 6. Gently strike the circumference around the V-band with a plastic hammer, etc. to fit the connection. 7. Install the T-bracket correctly in the latch. fter fastening the tightening nut to the prescribed position, insert the pin for confirming the tightening position. Refer to the back of page 796, Specific Product Precautions 4. 7 Note) Please use caution for burns in the case of a high temperature. aution When restarting this product or performing the air release works after replacing the elements, refer to the back of page 796, Specific Product Precautions

5 Bag Filter Series FGF Model Selection and Flow haracteristics. Determine the material for the vessel, gasket and O-ring after confirming operating fluids. 2. Select a vessel model by referring to the maximum flow rate in the specifications, (page 782) after confirming the operating flow rate.. onfirm whether the operating pressure and temperature is within the specification range (page 782) or not. 4. alculate the nominal filtration accuracy of an element that is required.. onfirm the flow rate and pressure drop based on the below flow characteristics when selecting a vessel and an element. 6. Determine a model by the element size, (ø90 x l770) when many contaminants (pollutants) are contained in the fluid. 7. Select the required option. 8. Determine the filter model according to the model selection procedures above. (Refer to page 782.) Flow haracteristics Flow rate per element Graph : Flow haracteristics of Series FGF Fluid: Water, Temperature: Room temp. The flow rate per element can be obtained as follows using Graph and Table B. Note ) The flow characteristics does not change according to the element size. The life expectancy changes in proportion to the filtration area. Note 2) We recommend that the pressure drop be calculated by 7 kpa. Much pressure drop in the initial stage will substantially shorten the service life in an element in the case of a highly turbid fluid. <alculation methods> (Example) Viscosity 00 m 2 /sec Pressure drop 7 kpa Nominal filtration accuracy 00 μm ) ccording to Graph, Flow haracteristics, the flow rate, 400 l/min is obtained from the point of intersection of the 00 μm line and the y-axis. 2) Next, according to Table B, Viscosity onversion Table, the flow coefficient is obtained as 8% for 00 m 2 /sec. ) The flow rate 400 l/min multiplied by the flow coefficient 8%, that is 280 l/min, gives the flow rate per element. 400 l/min (flow rate) x 8% (flow coefficient) = 40 l/min Pressure drop (kpa) 00 μm, 0 μm 2 μm 0 0 μm, 00 μm 7 q Flow rate (l/min) Table B: Viscosity onversion Table Viscosity (mm 2 /sec) 0,000 8,000 6,000 4,000 2,000,00, Flow coefficient (%) Multiply the number of elements by the flow rate per one element in case that the flow rate of including or elements is calculated. 78

Refer to front matters 42 and 4 for Safety Instructions and consult instruction manuals for details Mishandling will likely cause fluid leakage or removal of a cover, which may lead to an unexpected accident. lso, adaptability of equipment should be determined by a fully knowledgeable and experienced system designer. Please be sure to observe the following precautions, taking into consideration the damage prevention of an element, preservation of the poduct peformance and the maintenance performance. Operating ondition Range Warning. Operating pressure Do not use the product above its pressure range. 2. Operating temperature Do not use the product above its temperature range. Operating fluids ) Never use the product with gases 2) Do not use the product with corrosive fluids ) Do not use the product with fluids which will likely cause the expansion and deterioration of O-rings or the element. 4. Operating environment ) Do not use the product in an atmosphere if it may be corrosive. 2) Do not use this product in a place where shock or vibrations occur. aution on Design and Installation aution. Pressure drop (ΔP) Use the product with a flow which has an initial pressure drop which will become 7 kpa or less 2. Installation space rrange the necessary space for inspection, before installing and piping the product..

When using the product at a high temperature, take measures to prevent a burn from occurring 7. Provide circuits for releasing drainage and fluids. Warning aution on Operation. Replace the elements only after confirming that the pressure is zero. (Open the air release valve.) 2. The parts used for tightening the cover (V-band, etc.) must be properly positioned when attached.. Replace the deteriorated or expanded O-ring or gasket. O-ring or gasket replacement should be performed within one year after usage or when fluid leakage occurs. (Reter to page 784. omponent parts and Seal list.) 4. When applying pressure for starting a pump, etc., be sure to release the air by opening the release valve on the top.. If a part used for tightening the cover is deformed or the threads are galled, it must not be used. (Refer to page 784, omponent parts and Seal list.) aution aution on Operation. Replacement of elements Replace the element only when the pressure drops (ΔP) reaches 0. MPa 2. Surface temperature of a filter onfirm that the surface temperature of the filter is 40 or less, to prevent a burn from occurring.. leaning of each component In order for firm sealing to take place, clean the sealing surface of the O-ring or gasket and/or remove the paint which is left on the tightened parts of the cover or the thread parts. 4. When applying a pressure to start up a pump, confirm that the valves in the piping are sealed when opened or closed and that each connecting parts are completely sealed. If any abnormality is found, such as air leakage, stop the product immediately. The possible cause of the failure should be located. Resume operation after taking appropriate measures to stop the air leakage, such as replacing the O-rings, or additionally tightening the fittings. 79
