F25385 (May 2010)
POSSIBLE CAUSES
1. Filter screen plugged.
2. Clog in filter system lines.
NOTE: If using solid shortening, when all filtered shortening
is returned to the fry tank and filter power switch is off, open
the filter drawer approximately one inch. Allow the remaining
shortening in the line to drain into the filter tank to prevent
possible clogging after the shortening cools and solidifies.
Close the filter drawer when complete.
3. Shortening below 300°F to thick.
4. Fill solenoid valve malfunction.
5. Interconnecting wiring malfunction.
6. Pump is inoperative.
