Setting Up the Filter System
The following steps will get the filter setup correctly, remember the thumbscrew and nut will
only ever need to be fitted once, then it's only a matter of fitting the soaked Filter Cartridge
onto the stainless spindle and screwing it on.
The Thumbscrew, O-ring and Nut shown below make up the fitting that the spindle will screw
into and will be fitted first onto the Top Bucket (the one with the small hole in the base)
1. The thumb screw fits through the bucket base, the O-ring is fitted under the bucket
base.
2. The nut which is done up tight with the recess for the O-ring facing up (toward the base
of the bucket as per photo below) and will tighten over the O-ring. Finger tight should
ensure no leaks, do not over tighten!
