  1. Processing capacity figure based on water source standard purity level of 150μS/cm. Capasity may vary according to water quality.
  2. Processing capacity is not based on circulating water flow system. Ion exchange resin lifespan and water quality may fluctuate depending on the properties of the wetted parts and suefaces, as well as the particular working environment.
  3. It is recommended that the initially supplied water be either water that has been purified by having passed ehrough an ion exchange resin, or be commercially purchased deionized water. If tap water (or a similar grade of water) is used, the effective life of the ion exchange resin will be greatly reduced. In this case, please replace the ion exchange resin with the apare soon. (Ion exchange resin assemblies A, B, C, and F only.)
  4. Ion exchange resin assemblies D and E are wall mounted. Please confirm that there is a suitable installation place before installing the filter. A stand mount is available as an accessory (sold separately). (The mounting hole positions of Ion Exchange Resin D and E assemblies are the same as the mounting hole positions on Water Filter A and B assemblies respectively. Please refer to the Water Filter Equipment page for details regarding dimensions.)
  5. on Ion Exchange Resin D and E assemblies, if there is a chance that the water pressure within the purification vessel will exceed 0.2MPa, a pressure reducing valve should be installed.
  • Avoid installing the ion exchange resin where it will be in direct sunlight or in places where there is a risk of it being damaged.
