When frypot empties into filter pan, turn
return handle to ON. Filter pump will
activate.
The oil moves through the filter, the frypot
and out the open frypot-drain during filtering.
Allow the oil to circulate through the pot for 5
minutes. This process is called polishing the
oil. Polishing cleans the oil and washes
small particles from the frypot.
Close the drain-valve and leave the filter
pump on.
With the drain-valve closed, the frypot fills
with oil.
