CHAPTER 6: TROUBLESHOOTING
6.1 Oil Does Not Re-circulate In Filter and/or Does Not Return To Fryer.
A.
System may be plugged with solid shortening in pan sump or in pump. The pump operates
without circulating oil. See Section 4.5.2 & 4.5.3.
B.
Check for loose connections in the suction line. Tighten all loose fittings.
C.
Shortening may have solidified in internal return lines; see section 4.5.4.
6.2 Rate Of Oil Return To Fryer Slows.
A.
Filter paper is plugged due to too much sediment in fryer. Scrape top filter paper (or replace)
after each filtering cycle and filter the oil more frequently.
B.
Paper may be plugged by improper use of filter powder. Replace top filter paper and apply
the correct amount of filter powder, according to labeled directions.
C.
Sediment may be collected around suction pipe in filter bottom. Remove the paper support
grid and clean out sediment, ensuring that all five inlet ports are free of sediment.
