than those listed here.
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 temper-
ature and humidity fluctuate greatly.
2.
When used in locations where power fluctuation (voltage, fre-
quency, 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 vibra-
tions 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.

When used in locations where the machine is started and
stopped frequently or operation time is long. (Example: 24
hour air-conditioning)
