3-8. FILTERING OF
SHORTENING
(Continued)
3-20
9. When the pump is pumping air only, the shortening in the frypot
will appear to be boiling. Close the filter valve first and then
move the main power switch from PUMP to OFF. This will
keep the filter pump and lines from filling up with shortening.
When bubbling occurs, immediately close the filter valve. This
prevents aeration of the shortening, therefore increasing
shortening life.
10. Check the level of the shortening if necessary, until it reaches the
level indicator line on the rear wall of the frypot, or the top level
indicator line on model 500s..

11. After completing the filtering operation, empty and
replace the condensation drain pan.
12. If frying is to be continued at this time, move the main power
switch back to the ON position, and allow time for reheating of
the shortening.
