VI Maintenance/Inspection
1. Maintenance/Inspection Schedule
Having the units inspected by a specialist on a regular basis, in addition to regular maintenance such as changing the filters,
will allow the users to use them safely and in good condition for an extended period of time.
The chart below indicates standard maintenance schedule.
(1) Approximate Longevity of Various Parts
The chart shows an approximate longevity of parts. It is an estimation of the time when old parts may need to be replaced or
repairs need to be made.
It does not mean that the parts must absolutely be replaced (except for the fan belt).
Please note that the figures in the chart do not mean warranty periods.
(2) Notes
Œ
The above chart shows a maintenance schedule for a unit that is used under the following conditions:
A. Less than 6 times per hour of compressor stoppage
B. The product is assumed to be operated for 24 hours a day.
Œ
Shortening the inspection cycle may need to be considered when the following conditions apply:
1) When used in high temperature/high humidity area or when used in a place where the temperature and/or humidity
fluctuate greatly
2) When plugged into an unstable power source (sudden change in voltage, frequency, wave distortions) (Do not exceed the
maximum capacity.)
3) When the unit is installed in a place where it receives vibrations or major impacts.
4) When used in a place with poor air quality (containing dust particles, salt, poisonous gas such as sulfuric acid gas and
sulfuric hydrogen gas, oil mist).
Œ
Even when the above maintenance schedule is followed, there could be unexpected problems that cannot be predicted.
