2. Belt tightening:
a. Tighten the belts by turning the tensor screw -1-.
b. Measure the tightness of the belts. In the event that you do not have a tension gauge, use the
following practical method:
• Apply a 5kg force on the middle of the cord, perpendicular to it.
• With this force the belt must be displaced by between 12 and 14mm.
3. It is recommended to check the tension of the belts twice during the first 24 hours of operations.
Air filters
The air filters should be replaced by new ones of the same type and size, as required.
Slide the unit filters out on their guides to replace them.

Visually inspect the indoor coil when performing air filter maintenance.
The complete surface of the fins must be kept clean. If they need to be cleaned, use a soft brush or a
vacuum cleaner, taking special care not to damage the fins.
