MF90 SERIES PORTABLE FILTRATION SYSTEMS 

CHAPTER 3:  FILTER PREPARATION 

 

 

3-1 

3.1  Assembling The Filter System 

 

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.

 

 

 

 

WARNING! 

Water or boil-out solution 

MUST

 not be allowed to drain into the filter pan or filter 

system.  Irreversible damage will result if water is allowed into the system, and the 

warranty will be voided. 

 

 

The MF90 portable filtration system uses a filter support grid, one sheet of filter paper and a hold-

down ring to secure the filter paper in place.  

 

 

3.1.1  Filter Paper Configuration 

 

See illustration for proper assembly.

3.

 

Filter Paper (one sheet) 

4.

5.

 

Filter Pan Assembly 

 

  

 

A.

 

First, place the support grid in the bottom of filter pan. 

 

B.

 

Place one sheet of filter paper on top of the support grid.  Be sure the paper covers the whole 

filter pan bottom. 

 

C.

 

Position the hold-down ring on top of the filter paper and latch the hold-down ring and filter 

paper securely against the filter pan bottom, forming a tight seal.  

 

D.

 

Sprinkle  8  ounces  of  filter  powder  over  the  filter  paper,  distributing  the  powder  as  evenly  as 

possible.    If  filtering  a  second  frypot  immediately  after  the  first,  add  only  4  ounces  of  filter 

powder for the second filtering. 

 

E.

 

Place the crumb catcher screen (if applicable) in the filter pan.  Allow the crumb catcher screen 

to rest on the top edges of the hold-down ring.  

 

F.

 

Place filter pan cover onto the filter pan assembly.
