The following tables are applicable when using equipment under the conditions below.
Normal use without frequent START/STOPs (The number of START/STOPs is assumed to be less than 6 times
per hour in normal use.)
Operating hours are assumed to be 10 hours per day/2500 hours per year.
When the equipment is used under the following conditions, the "maintenance cycle" and "replacement intervals"
may be shortened.
When equipment is used in an environment where the temperature and humidity are high or change dramatically
When equipment is used in an environment where power supply fluctuations (the distortion of voltage,
frequency, and waveform) are large (Only within the allowable range)
When equipment is used in an environment where the unit may receive vibration or mechanical shock
When equipment is used in an environment where dust, salt, toxic gases such as sulfur dioxide and hydrogen
sulfide, and oil mist are present
When equipment starts/stops frequently and operates for long periods (24-hour air-conditioning operation)
