Warning

• Do not operate the product outside of the specifications.
  • Operating pressure : If pressure outside of the specified range due to such things as water hammer or surge pressure is possible, install an accumulator. When the product is used for gas, the maximum operating pressure shall be 0.5Mpa.
  • Operating temperature : Even if the specified temperature range is satisfied, the product cannot be used if the temperature is over the boiling point of the operating fluid.
  • Fluid : Do not use fluid which is harmful to the human body.
  • Do not use any fluid which will cause the seal or element to swell or deteriorate.
  • Operating environment : Note that the valve is not for outdoor use. – Do not use the product where it can be exposed to vibration or impact.
  • Do not use in environments where there is a danger of corrosion.
• Do not use the product with flammable or highly permeable fluids.
  • Usage may cause a fire, explosion or leakage.
• Do not disassemble with pressure applied.
  • Never loosen the connecting part (bolt) while pressure is being applied to the product. Make sure that the gauge pressure in the line is zero before loosening the bolts. Otherwise it may cause an injury.
• Do not modify the product.
  • Broken parts may cause an injury or failure.

Caution

• Do not touch the filter or piping when hot fluid is used.
  • Using this product at high temperatures (40 to 80 oC) may cause burns.
  • Do not touch the surface until it is cooled down to less than 40oC.
• Connect IN and OUT correctly. (Make sure that reverse flow will not be generated)
  • Make sure that back flow will not be generated. The element might break due to exposure to back flow.
• Perform regular leakage inspections and release trapped air when supplying pressure after the maintenance.
  • Stop operation if there are abnormalities such as leakage. Do not restart operation until the corrective action (replacement with a new gasket, retightening of the fitting etc.) is taken.
  • Release the air.
• Determine the replacement period of the element by referring to the differential pressure.
  • Replace the element when the differential pressure reaches 0.1MPa. If the element is not replaced, the element can be damaged.
• Wear personal protective equipment when replacing the element.
  • When replacing, make sure to wear protective gloves, protective glasses, etc. Fluid and captured foreign matter may cause injury.
• Make sure that load such as vibration or weight is not applied to the filter piping.
  • Fix the IN/OUT piping to the base using U bolts, or fix to the panel using a bracket. Otherwise, the filter may be damaged.
• High-viscosity fluids generate large differential pressures at low temperatures, which can damage the element.

Installation and Piping

Installation

1. When installing, allow sufficient space for maintenance. Reserve a space of 100mm or more beneath the reservoir.
2. Start with a flow with an initial differential pressure across the element of 0.02 MPa or less. If operation starts with differential pressure exceeding 0.02 MPa, the element replacement will be shortened significantly.
3. This filter generates particles at first. Before initial operation, flush the piping enough to remove the particles completely.

Piping

1. Check each port size for selecting valves and fittings suitable for operating conditions. Please check Safety Instruction before use.
2. For filter piping, apply a spanner to the filter cover so that force is not applied to the filter case.

Maintenance

Make sure periodically that there is no leakage from around the seals. Periodically check the pressure, temperature, surge pressure, etc. to make sure they are within the specified range of the filter. Replace the element before the differential pressure across it reaches 0.1 MPa due to clogging. Element is a disposable product. It cannot be cleaned

Replacement of element should be performed according to the procedure below.

Removal of the element

1. Stop operation.

2. Check following before maintenance.
   Confirm that the pressure of the system in which the filter is installed is zero, When using the product at a high temperature, be sure to check that the surface temperature of the filter container is not more than 40 oC before starting operation in order to prevent burns.

3. After closing the piping valve on the IN side of the filter, close the piping valve on the OUT side of the filter.

4. Loosen the air vent and release the residual pressure of the filter completely.

5. Discharge the residual fluid inside from the drain port.

6. Loosen the clamp ring with a tool such as a belt wrench and remove bowl and then the element. (Be careful not to lose the clamp ring.)

7. Clean the parts of the filter which are visibly dirty. If the gasket or seals are deteriorated or swollen, replace them with new ones.

Mounting of element

1. Assemble in the reverse order of section 6 Maintenance 【1】.
2. Set the element as below.
3. Make sure that the bowl and the sealing surface of the cover are not scratched.
4. Align the bowl in the gasket groove.
5. Set the element in the bowl. Center the element in the bowl. (If there is enough maintenance space, it is possible to attach the element to the cover and then attach the bowl.)
6. Set the clamp ring to the bowl as in Fig. 2.
7. Lightly align the seal part of the element with the sheet of the cover.
8. After screwing the clamp ring into the cover by hand, tighten it with a belt wrench.
9. Set the seals and plug of the drain part, and tighten the hexagon bolt of the air vent.

Restart the operation

1. After the replacement of the element, check the parts are assembled correctly before restarting operation. In case of fluid leakage, stop the operation immediately. Check the sealing condition and take corrective actions.
2. When supplying pressure by starting the pump, open the relief port (hexagon bolt) to discharge air. After the air is released, close the air exhaust port (hexagon bolt) and start operation
