28-9266-70 AA Sightglass cover assembly instruction

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 air trap inlet and outlet from the system

valves.

• Loosen and remove four bottom nuts (E) and washers from

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: Do not remove the dome nuts. Ensure that the dome nuts

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 trap and

mount the nuts (C).

Note: The lock washer should be closest to the nut.

• Tighten the nuts using a torque of 3 Nm (±0.3 Nm). 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.
