Installation of Filters into Filter Holders
Installation of filters into the filter holders requires care and patience to avoid damaging the
threads as well as the filters. The following procedures describe this process and should be
practiced with a drop-in (or slide-in) filter holder before attempting to load filters into the
filter cups.
Figure 2-10. Removing the retaining ring
The threaded retaining ring has two notches cut into it, 180 degrees apart. Place the teeth
(for 25mm; Figure 2-10) or notches (32 or 50 mm) of the spanner wrench into the notches on
the retaining ring and carefully turn it counter-clockwise to unscrew it.
Once the retaining ring is removed, the spacer (and blank, if present) should be easily
removed. You should become familiar with the assembly of this retaining system. In
particular, you should develop a feel for turning the retaining ring without pushing down on
the driver or wrench. This is important because if you forcefully push on the filter holder
while you are trying to load a filter, you run the risk of scratching the filter if the tool slips
out of place!
