Installation 5 Installation 5.1 Preparing for installation Check the following points: • • • • • Machine freely accessible from all sides Do not close ventilation grids and holes Sufficient room for installing and removing pipes and for maintenance work, particularly for installing and dismantling the machine No external vibration effects Do not suck any hot exhaust air from other machines into the cooling system. The suction flange (Fig. 2/D), oil filling point (Fig. 2/H), oil sight glass (Fig.
PAGE 15
Installation 5.3 Connecting pipes WARNING Sealing or constricting of the exhaust air outlet (Fig. 2/B) may lead to severe or fatal injuries! In the aggregate an inside pressure can be higher and higher, which leads to the destruction of components! NOTICE Material damage resulting from the forces and torques of the pipes on the unit being too high. Only screw pipes in by hand. The pumping capacity of the vacuum pump is reduced if the suction pipe is too narrow and/or too long.

Installation 5.5 Connecting the motor DANGER Danger of death if the electrical installation has not been done professionally. The electrical installation may only be done by a specialist electrician observing EN 60204. The operating company has to provide the main switch. a) The motor’s electrical data is given on the data plate (Fig. 2/N) or on the motor data plate. The motors comply with DIN EN 60034 and are in protection class IP 55 and insulation class F.

Commissioning and decommissioning 6 Commissioning and decommissioning 6.1 Commissioning WARNING Improper use May lead to severe or fatal injuries. Therefore be sure to obey the safety instructions. CAUTION Hot surfaces When the machine is at operating temperature the surface temperatures on the components (Fig. 2/ Q) may go above 70°C. You must avoid touching the hot surfaces (marked with warning plates).
PAGE 18
Commissioning and decommissioning 6.1.1 Checking the rotation direction The drive shaft direction of rotation is shown by the rotation direction arrow (Fig. 2/O) on the motor flange. a) Start the motor briefly (max. two seconds) to check the direction of rotation. When looking at the motor fan, it must rotate clockwise. NOTICE Incorrect direction of rotation Operating in the wrong direction of rotation leads to damage to the machine.

Maintenance and repair 7 Maintenance and repair DANGER Danger of death from touching live parts. Before maintenance work disconnect the machine by pressing the main switch or unplugging it and ensure that it cannot be turned on again. WARNING Hot surfaces During maintenance work there is the danger of getting burnt on hot components (Fig. 2/Q …4/Q) of the machine. Wait for the machine to cool down. 7.

Maintenance and repair 7.2.2 Coupling The coupling sprocket (Fig. 6/k) is subject to wear and must be checked regularly (at least once a year). When doing this the cooling coil (Fig. 6/v1) must be cleaned each time by purging. m n v q CAUTION k v1 To check the coupling switch the motor (Fig. 6/m) off and ensure that it cannot be switched on again. Undo the screws (Fig. 6/s5) on the motor flange (Fig. 6/n). Remove the coupling half on the motor side (Fig. 6/q) and the motor flange (Fig.

Maintenance and repair 7.2.4 Oil removal open Fig. 8 Air oil remover closed WARNING Heavily contaminated air oil removing devices lead to increased pump temperatures and in extreme cases may cause the lubricating oil to ignite spontaneously. The oil separator elements (5x) can become contaminated by dust particles after they have been running for some time (power consumption and pump temperature increase). Replace these components (Fig.
PAGE 24
Maintenance and repair 7.3 Repair/ Service a) For on site repair work the motor must be disconnected from the mains by a qualified electrician so that it cannot be started up again accidentally. For repairs use the manufacturer, its branch offices or authorised dealers. Please contact the manufacturer for the address of the service centre responsible for you (see Manufacturer’s address).
