FILTERING THE OIL
Hot oil and hot parts can cause burns. Use care when operating,
cleaning, and servicing the fryer.
Filter shortening at least once a day.
1. Do NOT turn off the power to the fryer. Leave power on.
2. Insert the drain extension into the drain valve. Tighten only hand tight.
3. Direct the drain extension into the mobile filtering device that you want to use.
4. A cold fryer will not drain properly. Always filter shortening between 250°F
and 350°F. The shortening in the cold zone area will remain hard if the heat is
only on for a few minutes. If necessary, use the clean-out rod to carefully stir
the hard shortening to an area above the cold zone where it will melt.
5. Use the provided crumb scoop to remove the heavy debris lying on the bottom
of the tank.
6. Slowly open the drain valve to allow oil to flow from the fry tank to the filter pan.
Then open the drain valve all the way. Please note the gas burners will
automatically turn off at this point and DRAINING will appear on the digital
display for solid state models and DRAINING OIL will display on computer
models.
7. When fry tank is empty use the tank brush to remove any additional debris.
8. Close the drain valve. The display will change to; FILL TANK for solid state
models and FILL TANK for computer models.
9. Fill tank with new shortening. Fill to a minimum of the MIN level but no high that
halfway between MIN and MAX. Oil will expand as it is heated.
10. Press the Temp button on the display. The display will ask if the tank is full;
TANK FULL.
11. Press the TEMP button on the display a second time to confirm that the oil level
is correct in the fry tank. Once pressed, the gas burners will ignite and begin
heating the oil to desired temperature.
DRAINING THE TANK
1. Turn off fryer.
2. Insert the drain extension into the drain valve. Tighten only hand tight.
