PREVENTIVE MAINTENANCE PREVENTS COSTLY REPAIRS.
BECAUSE OF THIS PERIODIC INSPECTIONS ARE REQUIRED.
Remember that the Control Panel may program a notification parameter, for cleaning or
replacement of air filters depending on the number of hours of fan operation in the indoor section.
The filter should be cleaned with a vacuum cleaner or washed in soapy water.
The frequency for cleaning or changing the air filters will depend on the quality air in the area (fumes, vapors,
suspended dust particles, etc.).
Remember that the metal grille should always be toward the inside of the unit.
