• Measure the position of the end of the hexagon on the main shaft relative to the flange of the
tube.
• Memorize and note this value as "Length".
• Make sure that the knob of the locking device is lowered to disable rotation of the adjusting
disk.
• Turn the handwheel to adjust this "Length" to a value of "Depth" minus 35 mm.
• Position the tube on top of the ball valve, the extension of the tube (40 mm diameter) has to
slide into the ball valve. Mind the O-ring sealing in the flange of the ball valve, if damaged:
replace (size 55.56 x 3.53 mm).
• Fasten the tube to the ball valve using the clamping device. This device consists of two halves,
bolted together with 4 bolts M8 x 20 mm (only use grade 12.9). When properly positioned and
tightened: on opposite sides, where the ends of two halves meet, the clearance should be
equal, on each side approximately 3 mm.
