For units with 0% outdoor air and 100% return air, dry indoor coil, and standard G4 filters.

  C A U T I O N

Before consulting the tables, add secure drops to the pressure required for the installation due to:

• Accessories included in the unit, when appropriate. See 

Pressure drop in options/accessories

, see

on page 27

The motor pulley comes adjusted to an opening of four turns. See 

Regular maintenance tasks performed

by specialised personnel

, see on page 33for the belt adjustment and tightening procedure.

  C A U T I O N

• Before commissioning the installation, but after balancing the air distribution in the building, the supply

air flow should be checked.

• With clean filters the indoor fan should not exceed a 200 Pa suction vacuum.
