CHAPTER 4: OPERATING/FILTERING INSTRUCTIONS
4.1 Filter Operation (cont.)
To flush residual shortening and sediment from the frypot, place a clean metal container
under the frypot drain valve. Open drain valve and place the hose nozzle inside the frypot.
Turn the Suction/Off/Return switch to RETURN. Rinse and flush sediment and debris from
frypot, into the metal container. DO NOT OVERFILL THE CONTAINER. Turn the
Suction/Off/Return switch to OFF after rinsing the frypot.
Wipe any remaining oil or sediment from the frypot with a clean, dry cloth or paper towel.
Close the drain valve. Pour the contents of the metal container into the filter pan, using care
not to splash hot oil. Place the hose nozzle into the frypot and turn the Suction/Off/Return
switch to RETURN. Ensure all oil is returned to the frypot before turning filter off.
Allow the portable filter to cool, then remove and discard the filter paper. Clean the interior
of the filter pan and all components. Do not use detergent or water in the filter pan for
cleaning.
7. PF50S Gravity Drain:
Place filter pan directly under fryer drain valve and drain oil into the filter. Place the filter
a.
hose nozzle securely inside the frypot. Turn the Suction/Off/Return switch to RETURN to
start the filter pump (see illustration below).
Allow the oil to circulate through the frypot and filter for approximately 5 minutes (process
known as "polishing"). Polishing the oil produces maximum filtration and extends the life
of the oil. Rinse any residual oil or sediment from the frypot during the polishing process.
