取り付け上の注意
Caution in setting
1）このカタログは、イオナイザモジュール単½での仕様であり、½用環境や取り付け状態、取り付け部周辺の構造、
材料などにより、イオン・オゾン発生量がカタログを満足しない場合があります。
This datasheet is representative of typical application conditions. If used outside of our specification, Ion/Ozone
amount may not meet same performance levels.
2）ご½用の際には機器にイオナイザモジュールを取り付け、イオン・オゾンの発生量をご確認ください。
Please make sure the Ion/ozone generation in your end product has been evaluated in view of your specifications with
our product being mounted appropriately.
3)特に、開口部周辺に金属½やプラスチックが存在しますと、発生したイオン½オゾンが吸収される場合があります。
Please note that some metal or plastic parts located near the Ionizer element can affect the amount of Ion/ozone
amount. Please follow the clearance/spacing recommendations on section 7.1

警告
warning (Ion Element)
発生子直近では高濃度のオゾンが発生します。高濃度のオゾンを長時間吸い続けると、人½に悪½響を及ぼす恐れがあ
りますので、通電中は高濃度オゾンを吸引しないよう人½から距離を取ってご½用願います。
High-density ozone will be generated closest to the Ionizer element. Exposure to high-density ozone for prolonged
periods can be harmful to the human body. Please maintain appropriate distance from the human body so as not to
breathe high-density ozone while the Ionizer is operational (input voltage applied).
