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 point (Fig. 2/H), oil sight glass (Fig.
Installation 5.3 Connecting pipes a) Vacuum connection at (Fig. 2/A). b) Connect the vacuum line. 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. c) The extracted air can be discharged through the exhaust silencer (Fig. 2/B) or conducted away via a pipe.
Installation 5.4 Filling with lubricating oil a) Fill the lubricating oil (for suitable types see “Maintenance”) for the gear wheels and oil filling point (Fig. 2/H) up to the middle of the sight glasses (Fig. 2/I). b) Close the oil filling point. 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.
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).
Commissioning and decommissioning 6.1.1 Checking the rotation direction The intended direction of rotation of the drive shaft is shown by the rotary direction arrow (Fig. 2/O). 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.
Commissioning and decommissioning 6.2 Decommissioning/ storing Stop the machine a) Switch the machine off. b) If available close the cut off device in the suction and pressure pipe. c) Disconnect the machine from the electricity source. d) Depressurise the machine: Open the pipes slowly. The pressure reduces slowly. e) Remove the pipes and hoses. f) Seal the connections for suction and discharge nozzles with adhesive foil. see also Section 3.2.1, Page 11 6.
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) of the machine. Wait for the machine to cool down. 7.
Maintenance and repair 7.2.1 Changing the oil H M K Fig. 4 Changing the oil H Oil filling point I Oil sight glass K Oil discharge point M Oil recommendation plate I 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.
Maintenance and repair 7.2.2 Air filtering D Fig. 5 s1 f1 Air filtering D Suction flange f1 Mesh filter s1 Screws NOTICE Insufficient maintenance on the air filter The power of the machine lessens and damage may occur to the machine. Intake air filter: The mesh filter (Fig. 5/f1) must be cleaned by rinsing out or purging or replaced more or less often depending on how dirty the discharged medium is. Remove the suction flange (Fig. 5/D) after undoing the screws (Fig. 5/s1).
Maintenance and repair 7.2.3 Coupling s5 v q k n2 m Fig. 7 The coupling sprocket (Fig. 7/k)) is subject to wear and must be checked regularly (at least once a year). Coupling k Coupling sprocket m Motor n2 Fan housing q Coupling half on the motor side s5 Screws v Fan CAUTION Defective coupling sprocket Defective sprockets may lead to the rotor shaft breaking. To check the coupling switch the motor (Fig. 7/m) off and ensure that it cannot be switched on again. Undo the screws (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).
