Important
Causes of failure
Shorten maintenance interval if conditions of installation or operation are unfavorable.
In particular, ambient temperature has a great influence on failure. Maintenance interval is based on an ambient
temperature 5~40
℃ and a yearly average ambient temperature 25 ℃ .
Shorten the maintenance interval if temperature exceeds the foregoing. If not, it can cause failure.
Maintenance interval is not a guarantee period.
Exceeding maintenance interval
Operation exceeding maintenance interval increases risk of failure and accidents.
When maintenance interval has elapsed, be sure to contact either our sales branches who sold it to you or local
sales.
