POWER/PUMP Switch
A three way switch with center OFF position; move the switch to
the position marked POWER to operate the fryer; move the switch
to the position marked PUMP to operate the filter pump; certain
conditions must be met prior to operation of the filter pump; these
conditions are covered later in this section
Frypot
This reservoir holds the cooking shortening, and is designed to
accommodate the heat exchanger, 6 head of product and an
adequate cold zone for collection of cracklings
Carrier
This stainless steel carrier consists of five racks which contain
the food product during and after frying
Drain Valve
A two-way ball valve, normally in the closed position; turn the
handle to drain the shortening from the frypot into the filter drain
pan
Drain Interlock Switch
A microswitch that provides protection for the frypot in the event an
operator inadvertently drains the shortening from the frypot while
the main switch is in the POWER position; the switch is designed to
automatically shut off the heat when the drain valve is opened
Shortening Mixing System
A shortening mixing capability to help ensure shortening is properly
mixed to prevent an accumulation of moisture and hence boiling
action in the pot; the filter pump is activated by the controls, at
preset intervals, to mix the shortening
Lid Latch
Air Valve
A mechanical catch on the front of the lid which engages a bracket
on the front of the frypot, when lid is lowered
Pumps air into the shortening, periodically, to keep the shortening at
a uniform temperature; this only functions when the unit has been
sitting idle for a period of time, and when heating upfrom a cold
start

SHORTENING
The shortening level must always be above the heating
elements when the fryer is heating and at the frypot level
indicators on the rear of the frypot (Figure 3-3). Failure
to follow these instructions could result in a fire and/or
damage to the fryer.
When using solid shortening, it is recommended to melt
the shortening on an outside heating source before plac-
ing it in the frypots. The burner tubes must be completely
submerged in shortening. Fire or damage to the frypot
could result.
1. It is recommended that a high quality frying shortening
be used in the open fryer. Some low grade shortenings have a
high moisture content and will cause foaming and boiling over.
To avoid severe burns when pouring hot shortening
into frypot, wear gloves and take care to avoid
splashing.
2. The electric model requires 100 lbs. (45 Kg.) of shortening.
The frypot has 2 level indicator lines inscribed on the rear
wall of the frypot which show when the heated shortening is at
the proper level. Figure 3-3.
3. Cold shortening should be filled to the lower indicator.
Figure 3-3
BE CERTAIN THE SHORTENING IS NEVER
ABOVE THE UPPER LEVELINDICATOR LINE.

WHICH COULD RESULT IN SERIOUS BURNS,
PERSONALINJURY, FIRE,AND/OR PROPERTY
DAMAGE.
1.
2.
To protect the shortening when the fryer is not in immediate
use, the fryer should be put into the Cool Mode.
Frying breaded products requires filtering to keep the
shortening clean. The shortening should be filtered at
least twice a day; after lunch rush and at the end of the day.
3.
4.
Maintain the shortening at the proper cooking level. Add
fresh shortening as needed.
Do not overload the racks with product (21 lbs. (9.5 kgs.)
maximum), or place product with extreme moisture content
into racks.
WITH PROLONGED USE, THE FLASHPOINT OF
SHORTENING IS REDUCED. DISCARD SHORT-
ENING IF IT SHOWS SIGNS OF EXCESSIVE
SMOKING OR FOAMING. SERIOUS BURNS,
PERSONALINJURY, FIRE,AND/OR PROPERTY
DAMAGE COULD RESULT.
3-8. FILTERING
INSTRUCTIONS
The Henny Penny gas 6 head open fryer, Model 290, must be
cleaned and the shortening must be cleaned and polished at
least twice daily; after lunch rush and at the end of the day.
Refer to KFC’s Standards Library.
Filter shortening immediately following a Cook Cycle when the
shortening temperature is in the Cool Mode; 250° F
(121° C) or less.
Drain the shortening at 250° F (121° C) or less. The
higher temperatures cause cracklings to burn on the
steel frypot surfaces after the shortening has drained.

After the initial installation of the fryer, as well as before every
change of shortening, the frypot should be thoroughly cleaned as
follows:
1.
Turn the POWER/PUMPswitch to OFF positioin, and unplug
unit from wall receptacle.
Moving the fryer or filter drain pan while containing
hot shortening is not recommended. Hot shortening can
splash out and severe burns could result.
The filter drain pan must be as far back under fryer as
it will go, and the cover in place. Be sure the hole in the
cover lines up with the drain before opening the drain.
Failure to follow these instructions causes splashing
of shortening and could result in personal injury.
2.
If hot shortening is present in the frypot, it must be
drained by slowly pulling the drain handle out towards you.
3.
4.
Close the drain valve and discard the shortening.
Raise lid, remove the racks and carrier from lid, and tilt lid
back, so that the lid won’t interfere with cleaning.
5.
Refer to KFC’s Standard’s Library on cleaning instructions.
If the cleaning solution in the frypot starts to foam and
boil over, immediately turn the POWER Switch to OFF
or damage to components could result.
Do not use steel wool, other abrasive cleaners or cleaners/
sanitizers containing chlorine, bromine, iodine or ammonia
chemicals, as these will deteriorate the stainless steel
material and shorten the life of the unit.
Do not use a water jet (pressure sprayer) to clean the
unit, or component damage could result.
Make sure the inside of the frypot, the drain valve opening,
and all parts that come in contact with the new shortening are
as dry as possible.
