MICRO-FLO BUILT-IN SERIES FILTRATION SYSTEMS

CHAPTER 4:  OPERATIONS

4.1 Initial Installation

On initial installation and before each use, remove all loose parts from the filter, wash the filter pan
and all accessories in hot, soapy water and dry thoroughly.

4.2  Assembling The Filter Pack

4.2.1  Models Prior to 1994

Micro-Flo filtration systems are shipped with a filter starter kit containing filter paper, filter powder
and other accessories.  Remove the filter hold-down ring, place two papers on the grid, and then
replace the hold-down ring.  It is essential that "Dean" filter papers are used; use of other than OEM
parts will void the warranty.  The remaining filter papers should be stored away from moisture for
future use.

The illustration below shows the proper assembly of the filter.
