Fig.11.5 Cleaning the surfaces of the internal air-filtration unit
Notes:
Only proceed to the next step when the acetone has completely
evaporated from the air-filter retaining disc and filtration unit.
Each of the fine filter-papers DS 0759 are packed between two
pieces of packing paper. The fine filter-paper is always white in
colour.
Remove a new fine filter-paper from its packaging using the
tweezers. Hold it by its edge. Refer to Fig.11.6. Lift the filter up and
place it inside the unit.
Fig.11.6 Placing a new filter-paper in the unit
Holding the handle-end of the unit between your thumb and fingers,
pick up the (dry) retaining disc and place it over the new filter-paper.
Refer to Fig.11.7 . Gently press the disc down over the filter-paper,
making sure that the disc’s locking tabs fit properly into the groove
in the unit and that the filter-paper stays in position and is not
damaged in any way.
Holding the handle-end of the re-assembled unit between your
thumb and fingers, place it back into position in the air-inlet of the
Monitor. Screw it back into its mounting. To do this, turn the unit
clockwise with your fingers to tighten until it is in position.
