Operating and maintenance instructions 5.2 Location WARNING: The pump must be installed in a protected area (see safety rules). It must be fastened with support feet on horizontal surface. It must be accessible for correct and easy maintenance, by respecting the minimum distances from possible obstructions (see figure 6). -
Page 11: Connection To The Machine
Operating and maintenance instructions 5.3 Connection to the machine The connection to the chamber to be pumped down must be carried out by means of pipes of the same diameter as the inlet port. Pipe weights and expansions, if any, must not rest on the pump. It is advisable to make the final connection to the pump inlet port with flexible pipes or fittings. -
Page 12: Electrical Connection
Operating and maintenance instructions 5.5 Electrical connection The control panel and electrical connections must be carried out by skilled personnel and conform to the EN 60204-1 rules or to other local regulations in the Country of use.

Page 13: Commissioning
Operating and maintenance instructions 5.6 Commissioning The pump is supplied without lubricating oil. NOTE: the operation without oil causes big damages to the pump. Carry out the first filling up through the plug (E) up to the half of the sight glass (F) and close the plug (E) (Figure 8). -
Page 14: Water Vapour Intake
Operating and maintenance instructions 5.8 Water vapour intake In order to pump down any water vapour, the following operations are recommended: Let the pump run for thirty minutes at the maximum vacuum in order to bring the pump temperature to its operating value. At the end of the working cycle, in case of further presence of condensate in the oil, let the pump run for at least thirty minutes at the maximum vacuum. -
Page 15: General Information
Operating and maintenance instructions 6.1 General information In order to keep the pump operating at a high efficiency level, it is mandatory to follow all periodical service points listed in the table below.However, more frequent service operations may be necessary depending on what the pump is used for (suction of con- densable vapours, suction of powders or polluting substances). -
