TROUBLESHOOTING (continued)
ANTI-MOLD WASABI CASSETTE
• Anti-mold elements with wasabi aroma prevents mold growth inside the dust box in which the dust collected
by filter cleaning operation is kept. Although only a trace amount of anti-mold elements is released, there may
be wasabi smell in the room depending on the environment in which the air conditioner is used. If you feel this
smell is unpleasant, block one of the anti-mold element outlets with a commercially available adhesive tape. If
this measure is taken, the amount of anti-mold element to be released will be reduced and the anti-mold effect
will also be less accordingly. To prevent mold growth, frequent cleaning of the dust box is recommended.
