page 4 of 27 Safety information! General information NOTICE Read and comply with this manual before installing or operating the equipment. Transport the pump at the provided handle. Remove all packing material, remove the product from its packing-box, remove the protective covers from the inlet and outlet ports and keep, inspect the equipment.
page 5 of 27 ☞ Avoid overpressure of more than 0.2 bar in case inert gas is connected to the pump, the gas ballast connection or to a venting valve. • • • • NOTICE Comply with maximum permissible pressures at inlet and outlet and pressure differences, see section ”Technical data”. Do not operate the pump with overpressure at the inlet. Check that mains voltage and current conform with the equipment (see rating plate). Connect pipes gas tight at inlet and outlet of the pump.
page 6 of 27 NOTICE • The pumps are not suitable for pumping substances which may form deposits inside the pump. Deposits and condensate in the pump may lead to increased temperatures even to the point of excessing the maximum permitted temperatures! • If there is a danger of formation of deposits in the pump chamber (check inlet and outlet of the pump), inspect the pump chambers regularly and clean if necessary.
page 7 of 27 • NOTICE Due to the residual leak rate of the equipment, there might be an exchange of gas, albeit extremely slight, between the environment and the vacuum system. Adopt suitable measures to prevent contamination of the pumped substances or the environment. Provide appropriate protective measures (i.e precautions which allow for the requirements of the respective application) even for the case of failure and malfunction. Failure of the pump (e.g.

page 12 of 27 Use and operation Installing in a vacuum system • • • • The gas outlet (hose nozzle 10 mm / silencer) must not be blocked. The exhaust pipeline has always to be free and pressureless to enable an unhindered discharge of gases. When using the silencer: Check the silencer regularly for chemical attack and deposits, replace if necessary or use an exhaust pipeline without silencer. • Reduce the transmission of vibration and prevent loading due to rigid pipelines.
page 13 of 27 During operation • • • • NOTICE Maximum ambient temperature: 40 °C Make sure ventilation is adequate if pump is installed in a housing or if ambient temperature is elevated. Potentially dangerous gases or vapours at the outlet of the pump have to be drained and disposed appropriately. Due to the high compression ratio of the pumps, pressure at the outlet port might be generated being higher than the maximum permissible pressure compatible with the mechanical stability of the system.
page 14 of 27 gas ballast In case of condensable vapours (water vapour, solvents, ...): ☞ Do not pump vapour until the pump has reached its operating temperature. ☞ Open gas ballast valve. The gas ballast valve is open if the arrow on the gas ballast cap shows towards the pump. ☞ With gas ballast valve open ultimate vacuum will be reduced, pumping speed is decreased. ☞ Use inert gas at the air inlet to avoid the formation of explosive mixtures. ☞ Close gas ballast valve by turning 180°.
page 15 of 27 Troubleshooting Fault Possible cause Remedy ❑ ➨ Knob for motor speed is turned to the left stop? ✔ Turn the knob to the right. ➨ Supply voltage is missing or too low? ✔ Check or connect the supply voltage; check the mains fuse. ➨ Overpressure in the exhaust line? ✔ Open exhaust line, ensure a free (pressureless) outlet line ➨ Motor overloaded? ✔ Allow motor to cool. Identify and eliminate the cause of failure. ➨ ✔ VACUU•BUS fuse has been triggered, e.g.

page 17 of 27 Replacing diaphragms and valves NOTICE All bearings are encapsulated and are filled with long-life lubricant. Under normal operating conditions, the pump is maintenance free. The valves and diaphragms are wear parts. If the rated ultimate vacuum is no longer achieved or in case of increased noise level, the pump interior, the diaphragms and the valves must be cleaned and the diaphragms and valves must be checked for cracks or other damage.
page 18 of 27 ➨ Use an open-ended wrench (w/f 17) to loosen the union nut at the hose connection next to the gas ballast. ➨ Use an open ended wrench (w/f 14) to turn the elbow fitting 1/4 of a turn, disconnect the hose. Do not remove the elbow fitting from the pump head. ☞ Through reassembly a leak may result. ➨ Use hex key size 5 to unscrew the handle from one side of the housing cover.

page 20 of 27 ➨ Lift diaphragm carefully. ➨ Apply pressure to the adjacent clamping disc to bring connecting rod into upper turning point position if necessary. ☞ Never use a spiky or sharp-edged tool to lift the diaphragm. ➨ Use the diaphragm key to grip the diaphragm support disc below the diaphragm. ➨ Apply pressure to the diaphragm clamping disc to bring the diaphragm into the lower turning point position.
page 21 of 27 ➨ Assemble head covers and valves. ☞ Check for correct position (see also fig. below).
page 22 of 27 Disassembling the housing cover at the side of the on/off switch ➨ Open hose clip by using a flat-bladed screw driver and pull off hose. ➨ Apply screw driver as shown and turn. ➨ Lay the pumping unit down with the housing cover at the side of the ON/OFF switch facing upwards (support pumping unit appropriately). ➨ Use a hex key size 4 to loosen the six socket head screws at the pump head. ➨ Raise the housing cover. ➨ Pull off the hose from the housing cover. Do not kink the hose.
page 23 of 27 Assembling the housing cover at the side of the on/off switch ➨ Position housing cover. Pay attention to correct hose guidance. ☞ Move housing cover slightly to make sure that the head covers are correctly positioned. ➨ Screw in the six socket head screws fixing the housing cover crosswise first slightly, then tighten. ☞ Do not tighten until head cover is in contact with housing, max. torque 6 Nm. ➨ Slip the PTFE tube onto the hose connection at the housing cover.
