CHAPTER 2: PARTS LIST

APPENDIX: ND90 Built-In Filter System Components

NOTES: Early model 24G fryers were available only as single units. To create multi-fryer batteries, a number of single fryers were battered together with top connecting strips.

To provide built-in filtration for these batteries, a filter (with a dump station above it) was placed somewhere in the middle, as shown in the photograph below. The filter system is referred to as the 44210ND90, or simply as the ND90.

The first generation filter returned the shortening to the frypot using a hose and wand assembly. Later versions used a so-called “hands free” plumbing assembly attached to the backsplash of the dump station.

The ND90 filter option was discontinued in 1996 when the fryer design was changed to incorporate the Under Fryer Filter (UFF) system. A large number of ND90-equipped fryers were produced and Frymaster/Dean continues to support them with replacement systems and parts, with the exception that the “hands free” plumbing components are no longer available.

A complete filter kit, illustrated below, may be ordered to replace existing ND90 filters in the field. The kit does not include the oil return hose and wand assembly. See page 2-19 for this part.
