ing allows for safe use of caster mounting. Our new power tilt
operates smoothly, with manual override that works easily
when needed, without the use of electric drills required by
other manufacturers. Construction: The UniVerse Skillet has
a textured stainless steel cooking surface with reinforcement.
Heating elements turn off automatically when the cooking pan
is raised to a tilted position. The skillet is provided with a
heavy-duty gas shock assisted cover with condensate vent.
The cooking pan and cover are mounted to a 1'/2" (38 mm)
square stainless steel tube frame, permitting access to floor
for easy cleaning. The closed-base model incorporates easily
removable stainless steel panels on the front and left sides.

DESCRIPTION
The Market Forge Electric UniVerse Tilting Skillets™ are
available in 30-gallon (87-liter) and 40-gallon (114-liter) pan
bodies with 12 kw and 18 kw inputs, respectively. Both
models are available in open-leg and closed-base frame
assemblies with manual or power tilt capabilities.
Benefits: Our UniVerse Skillets, unlike those of other braising
pan manufacturers that use clad plates, incorporate a uni-pan
design. This design reduces the potential for leaks and
eliminates the possi bility of pitting and surface rusting. The
new center-of-gravity tilt

TECHNICAL SPECIFICATIONS
Cooking Pan: The unitized cooking pan has no bottom welds
and is reinforced to resist cracking as expansion and
contraction occur. The textured cooking surface is machineapplied for a long-wearing, good appearance. The cooking
pan incorporates an easy-pour lip and 5-gallon increment
markings. Electric tubular heating elements are applied
directly to the underside of the cooking pan for better heat
transfer. An interlock switch is provided to cut power to the
heating elements when the pan is tilted more than 10° from
the normal horizontal cooking position. The counterbalanced
cover is pivoted from the frame using gas shocks to assist
lifting and ease of use. A lift handle is provided along the front
edge of the cover. A manually opened condensate vent is
positioned in the center of the cover.
Controls: The UniVerse Tilting Skillet™ comes standard with
a solid-state temperature controller with a positive OFF
position and 100°-450° Fahrenheit scale, a pilot light to
indicate when the electric heaters are ON, and a 1-hour
mechanical timer. Optional power tilting mechanism also
utilizes an UP/DOWN rocker switch. Manual tilting mechanism
uses a collapsible hand crank located below the control
panel. A high-limit temperature control is also provided The
control housing shall be water-resistant/splash-proof
Operation: The UniVerse Tilting Skillet™ Models 40-STEM
am 40-STEL will be rated at 18 kw. Models 30-STEM and 30STEM will be rated at 12 kw. All models are available in

INTRODUCTION
This technical manual contains general information, installation, operation, principles of operation, troubleshooting
guide, and maintenance information for the electrically
operated UniVerse Tilting Skillet. Also included is an
illustrated parts list and a directory of authorized parts and
service agencies.
Description
The Market Forge Industries UniVerse Models 30-STEL (12
kW input) and 40-STEL (18 kW input) are electrically
operated skillets, tilting type, with 30- and 40-gallon capacities, respectively. They are equipped with a solid-state
thermostat and high-limit control with a 100°F -to-450°F
temperature scale.
Basic Functions
The UniVerse Tilting Skillet is a very versatile cooking appliance. It can perform basic cooking functions, such as
brais ing meat, sauteing, pan-frying chicken, steaming
vegetables, boiling, and simmering. Refer to Section 4—
Test Kitchen Bulletin, which gives detailed information on
the various types of food products that can be cooked in
the skillet.
COOKING
1. Ensure that electric power connection has been made
correctly and that branch circuit breaker at building supply
box is ON.
2. Ensure that skillet is in full down position and clean before using.
NOTE: Electric power automatically shuts off when skillet
is tilted more than 10° above normal horizontal cooking
position.
3. Set thermostat at desired temperature by turning ther
mostat control knob clockwise. See Section 4—Test
Kitchen Bulletin for thermostat settings.
4. Preheat to desired temperature (with cover down)
before grilling, pan-frying, or any other method of cooking
except boiling.
NOTE: For best results, allow unit to cycle ON/OFF once.
5. Ensure that cover is up for most types of cooking
except for simmering, braising, or boiling. Cover has drip lip at rear to direct condensate into skillet.
6. Remove cooked food immediately to prevent overcooking. Tilt skillet by turning handcrank clockwise or
pushing tilt switch.
7. Lower skillet by turning handcrank counterclockwise on
pushing tilt switch.
SHUT-DOWN
Turn thermostat control knob counterclockwise to OFF
when no further heating is desired.
CLEANING
Unit must be cleaned after each use. Proceed as follows:
1. When all food has been removed from skillet, add water
to loosen/dissolve any remaining food.
2. Wash skillet using mild detergent, water and nylon
brush. If food is stuck to skillet surface, soak and use a
little heat to loosen food.
WARNING: Do not get water on wiring or in controls. Be
sure to wash inside of skillet pan, inside of cover including
under drip-lip. and pouring spout area.
3. Rinse and dry entire unit.

COOKING FACTS ON PARADE
1. The UniVerse Skillet is one of the most versatile pieces of
equipment to be found in any restaurant or institutional
kitchen.
2. This unit will stew, simmer, pan-fry, braise, grill, and
saute —and all with a very uniform heat pattern.
NOTE: Do not attempt to deep fry with your skillet!
3. For best results, the Tilting Skillet should always be preheated and allowed to cycle once.
4. A great deal of heavy lifting and transferring of foods from
one pan to another can be eliminated, and, therefore, pot
washing will be reduced.
5. This type of equipment usually reduces the total cooking
time by as much as 25% on combination dishes.
6. Sauces usually lose less moisture, as the cover reduces
evaporation.
7. Large batches of gourmet items can be prepared with less
work and with more uniform results.
8. Frozen vegetables can be cooked in the UniVerse Skillet
in the serving pan, then removed and transferred directly
to the serving line.
9. The following temperatures should be used:
Simmering: maximum of 200°F
Sauteing: 225-275°F
Searing: 300-350°F
Frying: 325-375°F
Grilling: 350-425°F
10. Temperatures of approximately 200°F should always be
used for milk-based products, or scorching will take place.
Lower temperatures (150-175°F) prevent thickening.
4-1
11. Some items should be started at a high temperature
and then reduced. This permits sealing for about 20%
of the time and cooking for the remaining 80%.
12. The cover has a lip at the back edge that directs the
con-densate on the cover back into the skillet.
13. The unit tilts easily to 90°, and receiving pan is
always approximately 2 inches from the pouring Up of
the skillet.
14. The stainless steel UniVerse Skillet is rapidly cleaned
with a mild detergent. Water, waste, and scraps are
eas ily removed into the receiving pan for disposal. (It
is always recommended that this type of unit be
presoaked if possible.)
15. Breakfast foods such as sausage, bacon, pancakes,
fried eggs, scrambled eggs, and French toast are a
few of the more common items that can be cooked in
the UniVerse Skillet.
16. When cooking meat or poultry, all pieces should be of
fairly uniform size and weight and should be turned at
least once while simmering.
17. This unit can be converted to a proof box by placing a
small amount of water in the pan to form steam and
then placing the food in another pan. The thermostat
should be set very low (100-150°F).
18. The unit can also be used as a holding cabinet by
adding water and setting the thermostat at
approximately 175°F.
19. When using water over and over for vegetable
cookery, be sure to add water occasionally to keep
level at about 3-4 inches. Thermostat should be set at
250°F.
20. Perforated 2 1/2 "-deep pans are suggested for
vegetables for the most satisfactory results. The pan,
can then be removed easily and transferred to the
serving line.
