9. Set-up and initial use

Only fully qualified personnel are allowed to set up this appliance, to install it or to carry out commissi-oning. Before commissioning and first use all packing protection must be re-moved from the compressor unit.

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.

11.1 Turning the compressor On / Off

Danger of too high pressure. If the maximum operating pressure (10 bar) is exceeded, then the com-pressor generator must be switched off and disconnected from the pow-er supply. - unplug at the mains and remove all power - inform your Service Technician

Troubleshooting

15. Tips for Operators and TechniciansAny repairs above and beyond routine maintenance must be carried out by suitably qualified personnel or one of our service technicians.

Before troubleshooting remove the unit from the mains supply.

Problem Probable cause Solution1. Compressor does not start. •�No�supply�voltage •�Check�the�mains�fusing,��

if�necessary�reset�the�switch�(if�the�cut-out�fuse�is�defect,�replace)�

•�Pressure�switch�not�swit-ched�on�

•�Switch�pressure�switch�on�•� Inform�the�Service�Technician

2. Compressor does not turn off

•�Compressor�is�too�small,�air�consumption�too�high

•�Calculate�the�amount�of�air�re-quired�(this�cab�ne�up�to�50�l/min�per�treatment�station),�if�necessa-ry�install�a�larger�compressor�

•�Leak�in�compressed�air�system

•�Find�leak�and�seal•� Inform�the�Service�Technician

3. Compressor switches on from time to time although no air has been used by operator.

•�Leak�in�compressed�air�system

•�Find�leak�and�seal•� Inform�the�Service�Technician

4. Loud knocking noises from compressor.

•�Bearing�damage •� Inform�the�Service�Technician

5. Fall in performance. Compressor needs longer to fill the pressure tank. For charge times see section 5. "Technical Data".
