Rules for Safe Operation
• All fryers are potentially
hazardous in that fire, electrical
shock, or burns may occur. The
hazard is increased in pressure
fryer operation because
shortening is under pressure.
The equipment must be installed
and serviced ONLY by
authorized service agents.
• All operating procedures must be
followed carefully
• If shortening begins to smoke
excessively, turn the fryer OFF
and immediately contact your
authorized service agent.

Start Up
1 Perform
safety
checks
• Check that drain valve is closed.
• Shortening level must be at OIL LEVEL line.
• Check level of fryer by looking at shortening level in frypot.
Shortening level in frypot should be equal distance from top of all
3 heater brackets. Adjust legs as necessary to level fryer.
2 Turn fryer ON,
heat
shortening
• Turn fryer ON. Make sure power lamp is ON.
• If in COOL MODE, press EXIT COOL, select product button.
HEAT ON light will cycle on and off until shortening temperature
reaches 185°F, then heat will stay on. Display will begin indicating
temperature at 255°F
3 Melt
shortening
in collector
• Push stirring tool through solid shortening to
bottom of collector. Stir and swirl shortening
until completely melted.
4 Check
collector
• Carefully feel exterior of collector bottom with hand to see if it’s
hot. If not hot, continue to stir until it is hot to the touch.
5 Install
heat plate
• Use heat resistant gloves and install heat plate using the collector
removal tool (diamond-shaped hole UP).
6 Heat
shortening
to DROP
temperature
• After droP is displayed, or HEAT ON light goes OFF, check
shortening level. If needed, add small amounts of shortening.
• To OIL LEVEL line inside rear of frypot.
• If overfilled, dip out excess shortening using a saucepan and use
later as add back.
• Ready to cook first round.

Discard Cracklings and Filter Shortening Twice Daily
• During a busy/high volume period or day when continually
cooking back to back rounds, cracklings may need to be removed
from collector more than 2 times each day. Failure to filter at
least 2 times daily will produce chicken with black specks and
will reduce shortening life.
• Refer to the procedure for type of filtering equipment being used.

Checking Fryer Recovery Rate – Monthly
• The fryer recovery rate check is necessary to determine if the fryer is
heating correctly. During start up, using a stop watch or a watch with a
second hand, start timing once the display reads 275°F. When the fryer
reaches 300°F, stop and note the length of time for the fryer to heat up.
Compare this to the ideal recovery range. If the time is higher than the
maximum recovery range, contact maintenance. If the fryers don't
recover in the allotted time, the product will not be cooked to KFC
standards.
Ideal Recovery Range
1 minute
Maximum Recovery Range
1 minute 30 seconds
Changing Shortening
Wear heat resistant gloves and goggles while
performing these steps.
• Shortening must be changed and inside of fryer
must be cleaned when visibility is less than
3" on visibility tester, if shortening smokes
excessively, or if off-flavors develop.
• Make sure grease barrel has room for old
shortening. DO NOT pour shortening down
floor drain.
Check visibility daily when shortening is at drop
temperature. You must change the shortening if
you can’t see the plate when shortening touches the
3” mark on the rod.
For details on using the visibility tester, see
"Shortening Management" chapter in
Standards Library Vol. 1.
