3. ume turn the adjustment screw 10 counter clockwise One full turn is equivalent to approx 1 litre less flush volume Proportioning of the flush volume To decrease the flush volume only press the operating lever 3 down lightly and for a short time To increase the flush volume press the operating lever 3 down for a longer time 0 Pressure Balance Bore Jet Bore Operation and Operating Principle The operating lever 3 is pressed This causes the lifting sleeve to rise and the auxiliary valve 8 to open and be pushed against the piston spring This in turn relieves the areas above and inside the piston of pressure The operating lever causes the piston to be pushed fully upwards The flushing process has now begun The operating lever is now released This causes the auxiliary valve to close the piston chamber This now fills with water via the pressure balance bore this process causes the piston to be pressed down against the valve seat the pressure in the piston chamber now gradually builds up to the prevailing mains pressure The flushing process is now complete Spare parts 122 6K Complete Piston piston 6 piston nipple 9 piston lip seal 19 piston seal 21 lip seal retaining ring 24 122 8K Complete Auxiliary Valve auxiliary valve 8 auxiliary valve seal 20 122 14K Complete Outlet Fitting outlet nut 14 tail pipe 15 seal 22 122 24 Set of Spare Parts 122 25 Set
