MAINTENANCE SCHEDULE
When properly maintained, the life expectancy of the units under normal operating conditions is in excess of
15 years.
We recommend checking and cleaning the unit every six months though this interval should be adapted to the
operating conditions.
It is recommended to thoroughly clean the unit at least once a year.
If it’s not used for a longer period we recommend turning the unit on for one hour every six months.
