Maintenance Manual
Actions to carry out after the parts have
been exchanged
1. First perform a heat disinfection program.
Refer to the AK 95 or AK 95 S Operator's
Manual.
2. After the heat disinfection; re-tighten the
nuts of the dialyser connector set to the
machine.
3. Let the machine pass FCH.
4. Control of the blood pump occlusion
Check surface on the roller at the pump
rotor, if it is damaged exchange the unit.
The roller unit should easily go back to
upper end position when it has been pres-
sed down to end position, exchange unit if
it gets stuck in any position.
Note! If the blood lines have a different
wall thickness, the occlusion of the blood
pump must be adjusted to the right size.
Use the gauge pins (stop/go) available in
the kit K40158001. The kit includes
following three different gauge pins:
T = 1.1 (Stop pin = 1.1*2*0.7 = 1.5mm)
T = 1.6 (Stop pin = 1.6*2*0.7 = 2.2mm)
T = 2.0 (Stop pin = 2.0*2*0.7 = 2.8mm)
T = wall thickness of the blood tubing
Use following formula to calculate which
gage pin to use:
2 * wall thickness * 0,7 (mm)

Check the range between the blood
pump rollers and the path according to
the picture below.
= Measuring
Adjust range between the blood pump
rollers and the path if it is necessary.
The GO pin should barely pass within
the calibrating area.
The STOP pin is NOT allowed to pass
in any point within the calibrating
area.
Note! Put grease on the GO and STOP
pins when not used and store gage in
plastic bag to prevent it from corroding.
Note! The gauge pins can also be
ordered separately:
T=1.1 (white) K40158002
T=1.6 mm (red) K40158003
T=2.0 mm (blue) K40158004
