10. Re-install the drop-in grid into the
fryer.
11. Once the drop-in grid is covered with
shortening, turn the fryer power switch
"ON" and push the reset switch (if
applicable).
12. When the oil in the fryer starts to
bubble, open the filter cabinet door,
then lift the front of the filter pan and
allow the bubbling to continue for
approximately 10-15 seconds more. If
it is blowing bubbles, air is moving
through the lines and the lines cannot
be plugged.
13. Turn the filter switch "OFF".
14. Close the oil return valve (or push in
the yellow handle) to the fryer and
close the fryer cabinet door.
NOTE: This completes the filtering of one
fryer. To filter additional fryers in the same
battery, repeat the process starting at step
3.b.1.
Complete the process with the following
final steps.
15. Close the hose connect valve (or push
yellow handle) at the fryer. Then open
the oil return line by turning the red
handle at the filter. This drains the oil
return line back into the filter pan and
clears the lines.
16. Close the filter cabinet door.
NOTE: With the hose connect valve
"closed" at the fryer and the filter oil return
valve "open", any oil left in the return lines
will drain into the filter pan and not be
trapped in the lines. These valves should be
kept in these positions when not filtering.
