1. Introduction

If you've already installed the external power supply for the filtration unit, skip to step 16.

Nah, it only takes about 30 minutes, and was not hard at all.  Much more convenient for it to be mounted on the enclosure.

A suggestion: if possible, just mount the power supply on your benchtop or elsewhere, and run the cable to the control unit on the front of the printer.  That will save you many steps inclduing removing the existing pwer supply and the front and rear enclosure feet.
