Page 4: Safety Information
page 4 of 28 Safety information! 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. If the equipment is damaged, notify the supplier and the carrier in writing within three days;... - Page 5 page 5 of 28 ☞ Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their accidental slipping. ☞ Check liquid level in both catchpots regularly and drain condensate in time. ☞ Check the overpressure safety relief device at the exhaust waste vapour condenser in appropriate intervals.
- Page 6 page 6 of 28 The motor is shut down by a thermal cutout in the winding. ☞ Attention: Manual reset is necessary. Switch off the pump or isolate the equipment from mains. Wait approx. five minutes before restarting the pump. ☞...
- Page 7 page 7 of 28 ☞ Ensure that the pump cannot be operated accidentally. Never operate the pump if covers or other parts of the pump are disassembled. Never operate a defec- tive or damaged pump. ☞ Attention: The pump might be contaminated with process chemicals which have been pumped during operation.

Page 12: Use And Operation
page 12 of 28 Use and operation Installing in a vacuum system: ☞ Avoid throttling losses by using connecting pipes with large diameter and keep them as short as possible. ☞ Reduce the transmission of vibration and prevent mechanical loading due to rigid pipelines. -
Page 13: During Operation
page 13 of 28 ☞ Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their accidental slipping. ☞ Ensure that the coolant outlet pipeline is always free and that it cannot get blocked. ☞ The gas outlet (hose nozzle 10 mm) must not be blocked. The exhaust pipeline has always to be free and pressureless to enable an unhindered discharge of gases. - Page 14 page 14 of 28 In case of low boiling solvents when the formation of condensate is unlikely, the use of gas ballast might be unnecessary. ☞ Operating the pump without gas ballast increases the solvent recovery rates at the exhaust waste vapour condenser. Attention: Notes concerning the operation of the exhaust waste vapour condenser ➨...

Page 19: Cleaning And Inspecting The Pump Heads
page 19 of 28 Disassembling the pump from the pump support (MD 4C + AK + EK / MD 4C + AK Synchro + EK) ➨ Use open-ended wrench (w/f 17) to remove union nut on the fitting of the cover plate. ➨... - Page 20 page 20 of 28 ➨ Use open-ended wrench (w/f 14) to turn elbow fitting 1/4 of a turn, remove hose. ☞ Do not remove the elbow fitting from the pump head. Through reassembly a leak may result. ➨ To check valves use hex key to remove four socket head screws from pump head and remove upper housing (hous- ing cover with housing cover insert), head cover and valves.

Page 21: Replacing The Diaphragm
Optimum torque for the diaphragm support disc: 6 Nm. ☞ The optimum torque is achieved if the pointer in the handle of the VACUUBRAND face wrench shows to the longer mark- ing line. Assembling pump heads: ➨ By turning eccentric bushing (front of connecting rod), bring connecting rod into a position in which diaphragm is in con- tact with housing and centred with respect to bore. - Page 22 page 22 of 28 Reassemble in reverse order. ➨ Install head cover, valves and housing cover with housing cover insert. ☞ Make sure that the valves are correctly seated: Valves at the outlet with round centred opening under valve, valves at the inlet with kidney-shaped opening beside valve.
- Page 23 page 23 of 28 If the pump does not achieve the ultimate pressure: ☞ In case the diaphragms and valves have been replaced, a run-in period of several hours is required before the pump achieves its ultimate vacuum. If all pump heads achieve a vacuum below 120 mbar but pump does not achieve the ultimate total pressure: Check hose connectors between pump heads and manifolds for leaks.
- Page 24 page 24 of 28 Cleaning and assembling components Overpressure safety relief device ......638821 (at the exhaust waste vapour condenser) ☞ Remove union nut at the condenser and remove hose from the inlet of the condenser. ☞ Pull off old overpressure safety relief device and install new one.
