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. 1/H), oil sight glass (Fig. 1/I) and oil outlet Fig.
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) The vacuum connection at (Fig. 1/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 electrical motor data can be found on the data plate (Fig. 1/N). 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.
Commissioning and decommissioning 6.1.1 Checking the rotation direction The drive shaft direction of rotation is shown by the rotation direction arrow (Fig. 1/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 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 NOTICE Insufficient maintenance on the air filter The power of the machine lessens and damage may occur to the machine. f d e h g The filter cartridge Fig. 3/f) must be cleaned by purging or replaced more or less often depending on how dirty the discharged medium is. Undo the screw buttonFig. 3/g). Remove the filter cover (Fig. 3/h) and gaskets Fig. 3/d/e). Remove the filter cartridgeFig. 3/f) and clean or replace. Re-assemble in reverse order. Fig.
Maintenance and repair Only lubricating oils complying with DIN 51506 group VC/VCL or a synthetic oil approved by Elmo Rietschle must be used. The viscosity of the oil must comply with ISO-VG46 as per DIN51519.Elmo Rietschle oil types: MULTI-LUBE 46 (mineral oil) and SUPER-LUBE46 (synthetic oil) see also oil recommendation plate (Fig. 4/M)). If the oil is subject to high temperatures (ambient or intake temperatures over 30°C, insufficient cooling, 60 Hz operation etc.
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.
