The air suction side of the initial air filter and the ventilation slats of the generator, as well as the suction grille of the cooling element must be free of any obstruction and there must be sufficient distance to walls or other units (ca. 20 cm). We strongly recommend that additi-onal ventilation is made available in the room. Where room temperatures above +40 °C are experienced then supple-mentary ventilation for the room is necessary, see fig. 3.

The use of a flexible pressure hose between the rigid pressure pipes and the compressor reduces the amount of vibration, thus reducing the amount of noise. Do not use a pressure hoses with strengthened electrical connection.

Use
11. Operation
At any sign of danger, separate the appliance from the power supply (unplug at the mains and remove all power).The compressor surfaces are hot! There is the danger of receiving burn injuries if contact is made with the hot surfaces.Automatic start up. When the pressure in the pressure tank falls, the compressor is au-tomatically switched on and then shuts down when the operating pressure set has been reached.
