Shortening of "maintenance cycle" and "replacement cycle" needs to be considered in the following cases:

  1. When used in hot, humid locations or locations where temperature and humidity fluctuate greatly.
  2. When used in locations where power fluctuation (voltage, frequency, wave distortion, etc.) is high. (Cannot be used if it is outside the allowable range.)
  3. When installed and used in locations where bumps and vibrations are frequent.
  4. When used in bad locations where dust, salt, harmful gas or oil mist such as sulfurous acid and hydrogen sulfide may be present in the air.
  5. When used in locations where the machine is started and stopped frequently or operation time is long. (Example: 24 hour air-conditioning)

Recommended replacement cycle of wear-out parts

[The cycle is not the same as the warranty period.]

Name of Main Part Inspection Cycle Replacement Cycle
Air filter 5 years
High efficiency filter (Optional accessory) 1 year 1 year
