Step 1 – Donning
1.
Slide your pre-filter material into your pre-filter holder. Make sure all of the small pre-filter
holder tabs are above the pre-filter material, to secure in place.
2.
Take your pre-filter holder and one of your F1100 range filters. Connect the two by clipping the
protruding circle area on the pre-filter holder onto the outside of the F1100 range filter
(circular opening) and turn clockwise.
a.
Start the pre-filter at a 12
°
– 35
° angle
(see pictorial instructions).
b.
If the pre-filter begins the mount at an angle less than 12
° or more than 35°, the pre-
filter will not mount correctly and this may cause breakages.
