with all Tiger instruments.
PTFE Filter Disc (861221)
The Filter Disc should be changed after every 100 hours of use. This
frequency should be increased for dusty or moisture laden
environments. or whenever the filter appears ‘dirty’ when viewed
through the transparent upper surface of the Filter Clamp.
Filter Disc changing should be conducted in a suitably clean environment, with clean hands and equipment
to avoid contamination of the new Filter Disc.
To change the Filter Disc, unscrew the Filter Housing Cap, lift off the Filter Clamp and O-Ring and lift the
Filter Disc from the Instrument Body. Carefully place a new Filter Disc into the Instrument Body. (Under no
circumstances should a Filter Disc be used once it has been removed.) Replace the Filter Clamp,
ensuring the locating lugs are correctly positioned in the cut-outs in the Instrument Body and that the O-Ring
is correctly seated. Replace the Filter Housing Cap. Do not over-tighten.
