ÄKTAprocess™ Air Trap sightglass cover
Air traps with part numbers listed in the table at the end of this document must be fitted with a metal cover for added protection in case the
air trap is subjected to a sudden overpressure.
Follow the instructions in this document to mount the cover assembly correctly on the air trap.
Note: For added protection, replace allthe sightglass mounting bolts with the enclosed 20 mm bolts as instructed below, before mounting the
sightglass cover assembly.
Note: After the sightglass cover assembly is mounted, the air trap should be tested for leakage and/or damage by applying an overpressure of
1.43 times the rated maximum pressure. This test shall be performed with the air trap filled with liquid. Inspect the air trap for any sign of
deformation before the system is taken into operation.
Sightglass cover assembly kit - parts list
Note: There are different variants of the mounting details and supports connecting the air trap to the ÄKTAprocess system frame. You may find
that the illustrations below do not exactly correspond to the mounting details on your specific system. Please contact GE Healthcare
service if you need advice or assistance when mounting the sightglass cover.

Align and tighten the sightglass assemblies
• Removeoneoftheoriginalbolts(E) fromthetopsightglass
assembly.
• Move the washer (F) from the original bolt to one of the
replacement bolts enclosed with the cover assembly kit.
Note: It is important that the new, longer bolts are used.
• Insert the replacement bolt through the sightglass bracket
(A)andtightenthefirstturnscarefullyby hand. Ensurethat
the bolt is positioned straight.
• Repeat the steps above for the other bolts, cross-wise.
• Ensurethatthesightglassassembly fits snuglyagainstthe
O-ring (D) in the air trap housing and that the
polypropylene spacer (B) and sightglass C are properly
aligned.
• Using a torque setting of 0.5 Nm, tighten the bolts cross-
wise, slowly and carefully.
• Verify that the sightglass bracket (A) is properly aligned
with the air trap housing.
• Increase the torque setting to 1 Nm and tighten the bolts
cross-wise.
Note: To avoid damage to the threads, it is important that the
procedureaboveisfollowed,with propertorquesettings.

Assembly mount procedure – 6 mm and 1/2 inch air traps
1 Disconnect the air trap and remove the bottom nuts
• Remove the TC coupling (A) and evacuation hose from the
top valve.
• Unscrew and disconnect the cable contacts (B) from the
level sensors.
• Disconnect the airtrap inlet and outlet from the system
valves.
• Loosen andremovefourbottomnuts(E) and washersfrom
the connecting rods that are fixed to the support (D).
Note: The nut on the fifth connecting rod does not need to be
removed.
Note: The washers from the two front connecting rods will not
be used when the cover is mounted.
• Lift the air trap from the support (D) and move it to a
suitable place to mount the cover assembly.
2 Pull out the connecting rods
• Remove the bottom nuts (C) from the two front connecting
rods.
• Pull the connecting rods (F) out of the air trap. Remove the
washers from the rods.
Note: Donotremovethedomenuts.Ensurethatthedomenuts
still are securely fastened. If loose, the nuts should be
fastened and locked into place using Loctite™ 243.
3 Mount the top sightglass cover part
• Place the top cover (G) on the air trap, with the opening
aligned with the sight glass.
• Re-insert the front two connecting rods (F) through the top
holes in the cover.
• Insert a plain washer and a lock washer on each of the
two front connecting rods underneath the air trapand
mount the nuts (C).
Note: The lock washer should be closest to the nut.
• Tighten the nuts using atorque of 3 Nm (±0.3Nm). Verify
also that the other three nuts are tightened, using the
same torque value.
• Return the air trap to the support (D), aligning the bottom
part of each connecting rod through the holes in the
support.
• Connect the air trap inlet and outlet to the system valves.
