Contact with hot shortening
will cause severe injury or
death. Wear protective
gloves and clothing when
operating or servicing this
fryer.
HAZARD
DANGER:
BURN
Do not attempt to open the
fryer lid until the pressure in
the frypot has fallen to zero.
Opening the lid prematurely
will result in the explosive
release of hot shortening.
Contact with hot shortening
will cause severe injury or
death.
HAZARD
DANGER:
BURN
Do not attempt to open the
fryer drain valve if the frypot
is under pressure.
Opening the drain valve under
pressure will result in the
explosive release of hot
shortening.
Contact with hot shortening
will cause severe injury or
death.
HAZARD
DANGER:
EXPLOSION
Failure to operate this
pressure fryer as described
in this manual can lead to
explosion, severe injury and/
or death.
HAZARD
SAFE OPERATION OF THE PRESSURE FRYER
Contact with hot shortening will cause severe injury to unprotected skin
and eyes. Extensive exposure to hot shortening can cause death.
Protect yourself from contact with hot shortening:
ALWAYS wear protective clothing when operating this pressure
fryer.
ALWAYS wear protective goggles, gloves and apron when
cleaning or servicing this pressure fryer.
Shortening under pressure can be very hazardous unless handled
properly:
DO NOT attempt to operate this fryer without the LID O-RING and
COLLECTOR O-RING properly installed.
Do not operate this fryer if either of the LID O-RING or
COLLECTOR O-RING are damaged. A damaged O-ring will lead
to shortening leaks and/or spraying shortening.
Be sure the LID is seated in the frypot and the OPERATING
LEVER is turned fully COUNTERCLOCKWISE before starting a
cook cycle.
DO NOT attempt to turn the OPERATING LEVER until the
pressure in the frypot has fallen to zero.
DO NOT open the drain valve if the frypot is under pressure.
Opening the lid or drain valve with the fryer under pressure will
result in the explosive release of hot shortening.
Spilled shortening will cause a slip and fall hazard:
Add shortening, replenish the shortening, and service the fryer
carefully to avoid spills.
Clean up shortening spills promptly to avoid creating a slip and fall
hazard.
DO NOT allow water to contaminate the shortening. Water will
boil violently on contact with hot shortening, causing the hot
shortening to splatter.
DO NOT heat water in the fryer
DO NOT use boil-out method to clean the frypot.
DO NOT clean the frypot with water, water spray or steam
spray.
DO NOT use steel wool to clean any part of the fryer.

Hi-Temperature Brush
Breading will build up at the oil line. This breading must be removed
from the cooking zone to prevent leaving burned specks on product.
Also, the elements must be kept free of breading crumbs and other
cooking debris to ensure optimum operation.
1. Remove the fryer basket from the fryer. Using the blade of the
FRYPOT STIRRING TOOL, scrape the built-up breading from the
oil line.
2. Using a hi-temperature brush, brush all breading and other cooking
debris from the face of the heating elements, and from between the
elements, element retainers and the frypot.
IMPORTANT: Be careful when cleaning around the temperature
probe and hi-limit thermobulb. Damage to either component will
put the fryer out of service.
3. Using a hi-temperature brush, push all breading and crumb s into
the collector.
4. Check the shortening level. Add shortening as required to bring the
level between the MIN OIL and MAX OIL lines.
5. Using the FRYPOT STIRRING TOOL, stir the frypot until all
shortening is melted. DO NOT stir into the collector.
6. Raise LID AND YOKE assembly (see page 8). Clean bottom of lid
then carefully return lid & yoke to horizontal position.
7. Check CONDENSATE TRAY. Empty if necessary and reinstall.

DANGER:
BURN
HAZARD
Contact with hot shortening
will cause severe injury or
death. Wear protective
gloves and clothing when
cleaning this fryer during
operation.
CAUTION:
SLIPPING
HAZARD
Avoid spilling shortening on
the floor. Clean up all spills
immediately to prevent
creating a slip and fall
hazard.
CAUTION:
HOT OIL
SPLATTER
HAZARD
DO NOT clean the frypot with
commercial boil-out products.
DO NOT clean with water or
steam spray. Water will boil
violently causing splatter
when the shortening reaches
temperature.
IMPORTANT:
Clean components with a
clean towel or sponge Scrub
with a soft bristle brush only if
necessary to remove food
particles.
NOTE: The following may
safely be cleaned in a
dishwasher:
Collector, heat transfer plate,
fryer basket, condensate tray,
