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 oil filling pointFig. 2/H), oil sight glassFig. 2/I) and oil outletFig.
Installation 5.3 Connecting pipes 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. The air vent (Fig. 1/B) must not be closed or restricted. Counter pressures on the outlet side are only permissible up to + 0.1 bars. Prevent liquids accumulating in the exhaust line. a) Vacuum connection (Fig. 2/A).
Installation 5.5 Connecting the motor DANGER Danger of death if the electrical installation has not been done professionally. The electrical installation must only be done by a qualified 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 (Fig. 2/ P1). 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. 1/Q) may go above 70°C. You must avoid touching the hot surfaces (marked with warning plates).
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 anti-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 and equipment During maintenance work there is the danger of getting burnt on hot components (Fig. 2/Q) and by the machine lubricating oil. Wait for the machine to cool down. 7.
Maintenance and repair 7.2.1 Air filtering f1 h Fig. 4 Air filtering D Suction flange h Non-return valve f1 Micro filter s1 Screws s2 Screws 20 | s2 D s1 NOTICE Insufficient maintenance on the air filter The power of the machine lessens and damage may occur to the machine. The micro filter (Fig. 4/f1) must be cleaned by rinsing out or purging or replaced more or less often depending on how dirty the discharged medium is. Also check the non-return valve (Fig. 4/h) for contamination.
Maintenance and repair 7.2.2 Coupling The coupling rubbers (Fig. 5/k) are subject to wear and und must be checked regularly (at least once a year).. You can tell when the coupling rubbers are worn by a knocking noise when the pump starts up. m q s4 CAUTION s5 Defective coupling rubbers Defective coupling rubbers may lead to the rotor shaft breaking l1 v1 l k q1 r v u Fig.
Maintenance and repair 7.2.3 Lubrication H M NOTICE Always change the oil when the machine is at operating temperature and in an atmospherically ventilated area. If it is not completely emptied the amount that can be refilled is reduced. The waste oil must be disposed of in compliance with the local environmental protection regulations. If you are going to use another oil type, empty the oil removing device housing and oil cooler completely. K I Fig.
Maintenance and repair 7.2.4 Oil removal t1 L L1 Fig. 7 Oil removal L Oil separator element L1 O ring T Purging cover s3 Screws T s3 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 element may be contaminated with particles of dirt when it has been running for a long time (power consumption and pump temperature increase). Replace the device (Fig.
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).
