OPERATING INSTRUCTIONS

HOT FOOD SECTION:

SINCE THE FOOD WARMING UNIT IS DESIGNED FOR HOLDING OR WARMING PRECOOKED FOOD, IT
WILL NOT OVERCOOK FOOD WHEN PROPERLY USED. THERE ARE THREE (3) WAYS OF
MAINTAINING HOT FOOD IN THE RECEPTACLE: 1. DRY HEATING, 2. STEAM HEATING AND 3. HOT
WATER HEATING.

PERSONNEL ONLY PER NATIONAL ELECTRICAL

1. DRY HEATING

A. SET THE CONTROL SETTING ON THE DESIRED POSITION AND ALLOW THE RECEPTACLE TO

PREHEAT FOR 20 TO 30 MINUTES.

B. PLACE THE CONTAINER OF FOOD IN THE RECEPTACLE. KEEP THE FOOD COVERED WHEN

NOT SERVING.

*** WARNING ***

NEVER POUR COLD WATER INTO A HOT FOOD PAN RECEPTACLE.

BOILS OUT, REFILL WITH HOT WATER OR WAIT UNTIL WELL HAS COOLED DOWN. IF COLD WATER
IS POURED ON A HOT, EMPTY RECEPTACLE IT WILL CAUSE THE WELL TO SPLIT OR CRACK.

2. STEAM HEATING

A. PLACE A FEW QUARTS OF COLD WATER OR HOT WATER (FOR A FASTER PRE-HEAT) IN TO

THE RECEPTACLE OR ABOUT 3/4 “ INCH OF WATER IN BOTTOM OF WELL. THE WATER
SHOULD NOT BE IN CONTACT WITH THE FOOD PAN. BOTTOM.PLACE A COVER OR EMPTY
FOOD PAN OVER THE RECEPTACLE AND SET THE THERMOSTAT TO A POSITION FOR
MODERATE BOILING NO. (7) SETTING ON CONTROLLER . ALLOW UNIT TO PREHEAT UNTIL
WATER BOILS IN ABOUT 40 TO 45 MINUTES.

C. PLACE THE CONTAINER OF FOOD IN THE RECEPTACLE. KEEP FOOD COVERED WHEN NOT

BEING SERVED.

D. SET THE THERMOSTAT TO A POINT WHERE THE WATER JUST BOILS NO (6) SETTING ON

CONTROLLER.

2. HOT WATER
A. PLACE A FEW QUARTS OF WATER IN THE RECEPTACLE WITH A DEPTH SO THAT THE

FOOD CONTAINER WILL NOT BE IN CONTACT WITH THE WATER.

B. PLACE A COVER OR EMPTY FOOD PAN OVER THE RECEPTACLE AND SET THE

THERMOSTAT TO A POSITION FOR MODERATE BOILING NO. (7) SETTING ALLOW UNIT TO
PREHEAT UNTIL WATER BOILS.

C. LOWER THE SETTING ON THE THERMOSTAT SLIGHTLY SO THAT THE WATER

TEMPERATURE IS JUST BELOW THE BOILING POINT NO. (6) SETTING.

D. PLACE THE CONTAINER OF FOOD IN THE RECEPTACLE. KEEP FOOD COVERED WHEN NOT

BEING SERVED.

EXACT DIAL SETTING TO MAINTAIN DESIRED FOOD TEMPERATURE WILL VARY WITH THE
CHARACTER OF THE FOOD, SUCH AS WHETHER OR NOT THE FOOD IS WATERY OR HAS A
CONSIDERABLE AMOUNT OF GREASE. THE MOST SATISFACTORY TEMPERATURE SETTING MUST
BE DETERMINED BY EXPERIENCE.

WITH STEAM AND HOT WATER HEATING THE DRYING OUT OF THE FOOD IS MINIMIZED BECAUSE
THE WATER VAPOR FROM THE RECEPTACLES CREATES HUMID AIR OVER THE FOOD.

THERMOSTAT:
THE THERMOSTAT WHENEVER THE HEATING UNIT IS ENERGIZED THE LOAD LIGHT COMES ON

AND GOES OFF WHEN THE PRESET TEMPERATURE IS REACHED.THE CYCLING OF THE
THERMOSTAT IS THEREFORE INDICATED BY THE LOAD LIGHT.

IF THE WATER

4. = 150 DEGREE WATER 9. = 212 DEGREE WATER

5. = 180 DEGREE WATER 10. = 212 DEGREE WATER
SHUTDOWN:

AT THE END OF THE DAY OR SERVING PERIOD, SET THE THERMOSTAT CONTROLS TO THE (1)
POSITION WHICH IS THE OFF SETTING. THIS REMOVES ALL POWER TO THE HEATING UNITS. TO
SHUT OFF THE EQUIPMENT FOR LONG PERIODS OF TIME OR TO PREVENT THE UNAUTHORIZED
USE OF THE EQUIPMENT PLACE THE CIRCUIT BREAKER TO THE OFF POSITION.

CLEANING

HOT FOOD WELLS:
WET OPERATION - IF HOT WATER OR STEAM HEATING IS USED, ALL SURFACES ARE COVERED

WITH A FILM OF WATER. FOOD SPILLAGE INTO THE RECEPTACLE WILL NOT STICK OR CARBONIZE.
IT WILL DROP IN TO THE WATER AN FLOAT OR SETTLE TO THE BOTTOM. TO CLEAN THE
RECEPTACLE, REMOVE THE WATER BY OPENING THE DRAIN VALVE LOCATED UNDER THE UNIT
AND DRAIN THE WATER IN TO A SUITABLE CONTAINER AND SPONGE OUT THE REMAINING
WATER. WASH THE RECEPTACLE WITH A MILD DETERGENT AND HOT WATER, RINSE AND DRY.
SEE THE FOLLOWING SECTION ON "HOW TO CLEAN STAINLESS STEEL" FOR SPECIFIC
RECOMMENDATIONS.

DRY OPERATION - WHEN THE FOOD WARMER IS USED DRY, FOOD SPILLAGE ON THE HOT
SURFACES WILL BURN AND STICK. THE SAME COMMERCIAL CLEANERS USED ON STAINLESS
STEEL UTENSILS MAY BE USED TO CLEAN THE RECEPTACLE. WASH THE INTERIOR SURFACES
WITH WATER AND A MILD DETERGENT TO REMOVE DISCOLORATION. RINSE WITH PLAIN WATER
AND DRY WITH AN ABSORBENT CLOTH. THE BOTTOM OF THE RECEPTACLE MAY TAKE ON A
STRAW COLORED APPEARANCE WHEN IT IS USED DRY. THIS IS DUE TO THE INTENSE HEAT. T HE
DISCOLORATION WILL NOT COME OFF WITH NORMAL CLEANING PROCEDURES BUT DOES NOT
POSE ANY PERFORMANCE OR HEALTH PROBLEMS. SEE THE SECTION ON "HOW TO CLEAN

STAINLESS STEEL" FOR SPECIFIC RECOMMENDATIONS.

*** WARNING ***

DO NOT USE HARSH CHEMICALS, ACIDS OR ALKALIS IN CLEANING THIS TABLE OR HEATING
RECEPTACLES. WITH ANY CLEANERS, READ INSTRUCTIONS CAREFULLY AND DILUTE AS
INSTRUCTED BEFORE APPLYING TO STAINLESS STEEL EQUIPMENT.

THE FOOD WARMING RECEPTACLE IS MADE OF STAINLESS STEEL, BUT USE CARE DURING THE
CLEANING OPERATION. HEAVY OBJECTS SHOULD NOT BE DROPPED IN THE RECEPTACLE.

LAMINATE BODY & STAINLESS STEEL BODY

THE LAMINATE BODY SHOULD BE CLEANED WITH A MILD NON-ABRASIVE CLEANER. STAINLESS
STEEL BODY, SEE SECTION IN THIS MANUAL “HOW TO CLEAN STAINLESS STEEL”

*** CAUTION ***

DO NOT USE BLEACHES, ABRASIVE CLEANERS OR ABRASIVE CLOTHS OR PADS AS THEY MAY
DISCOLOR AND SCRATCH THE SURFACE. DO NOT USE HARSH CHEMICALS, ACIDS OR ALKALIS IN
THE CLEANING OF THE STAINLESS STEEL.

PLEXIGLASS SHIELDS:

USE A MILD SOAP AND A SOFT CLOTH WHEN CLEANING THE PLEXIGLASS SURFACES. WIPING THE
SURFACE WITH A DRY CLOTH CAN CAUSE SCRATCHES.

DO NOT USE WINDOW CLEANING SPRAY OR KITCHEN SCOURING COMPOUNDS. PRODUCTS WITH
A HIGH ALCOHOL CONTENT CAN CAUSE SURFACE FISSURES COMMONLY REFERRED TO AS
"CRAZING". THIS WILL OCCUR IN ANY SPOT THAT HAS BEEN SUBJECT TO STRESSES, SUCH AS
CHIPPED OR BURNED SAW CUTS, CRACKED HOLES FLAME POLISHED EDGES, FORMED EDGES,
ETC. FOR BEST RESULTS USE "NOVUS PLASTIC POLISH NO. 1".

TEMPERED GLASS SHIELDS:

MANY TYPES OF WINDOW CLEANING SPRAYS ARE AVAILABLE FOR CLEANING GLASS

HOW TO CLEAN STAINLESS STEEL

THE FOLLOWING INFORMATION WAS TAKEN FROM A PAMPHLET BY MR. RICHARD E. PARET,
STAINLESS STEEL SPECIALIST, AMERICAN IRON AND STEEL INSTITUTE.

STAINLESS STEEL IS ONE OF THE EASIEST MATERIALS TO CLEAN AND KEEP CLEAN.
THE REASONS FOR STAINLESS STEEL'S EASE OF CLEANING IS EASY TO SEE; THEY LIE IN THE

NATURE OF THE METAL ITSELF.

1. IT'S HARD, TOUGH SURFACE. STAINLESS STEEL WILL WORK HARDER, THAT IS, THE MORE IT
IS USED, THE MORE RESISTANT TO WEAR IT BECOMES. STAINLESS STEEL WILL NOT DEVELOP
ROUGH SPOTS THAT HARBOR BACTERIA AND SOIL.

2. HIGH CORROSIVE RESISTANCE. STAINLESS STEEL IS PRACTICALLY UNTOUCHED BY THE
CORROSIVE ATTACKS OF MOISTURE, DETERGENTS, FOOD ACIDS, BLOOD SALTS AND OTHER
CORRODENTS CONNECTED WITH FOOD PREPARATION. THIS MEANS THAT STAINLESS STEEL
ALWAYS HAS A BRIGHT SURFACE FREE FROM OXIDES THAT CAN AFFECT THE FLAVOR OF
FOODS.

THE SECRET OF MAINTAINING STAINLESS STEEL IS FREQUENT, SCHEDULED CLEANING THAT WILL
PREVENT BUILD UP OF SURFACE DEPOSITS. SURFACE DEPOSITS, IF ALLOWED TO REMAIN FOR
LONG PERIODS OF TIME CAN HARM STAINLESS STEEL. STAINLESS STEEL THRIVES ON EXPOSURE
TO AIR; UNDER CERTAIN CONDITIONS, THE LENGTHY DEPRIVATION OF OXYGEN BY HEAVY SOIL
DEPOSITS CAN CAUSE LOCALIZED PITTING OR STAINING.

NEGLECTING THE MATERIAL IN THIS MANNER IS DEFINITE ABUSE, WHICH EVEN STAINLESS STEEL
IS NOT IMMUNE.

TWO BASIC RULES:

1. CLEAN FREQUENTLY, AND ON A FIXED SCHEDULE.

2. SELECT THE SIMPLEST METHOD.
TO REMOVE ORDINARY DIRT AND FOOD RESIDUE FROM STAINLESS STEEL EQUIPMENT THAT

OPERATES AT LOW TEMPERATURES, USE ORDINARY SOAP AND WATER AND APPLY WITH A
SPONGE, FIBER BRUSH OR CLOTH. TO HASTEN ACTION, ADD EITHER SODA ASH, BAKING SODA,
BORAX OR ANY OF SEVERAL NON-ABRASIVE COMMERCIAL CLEANSING AGENTS.

TO REMOVE SPLATTER OR CONDENSED VAPOR, WHICH HAVE "BAKED" ONTO THE EQUIPMENT,
THE TREATMENT OUTLINED ABOVE IS OFTEN SUFFICIENT. IN OTHER CASES A GENTLE TO
VIGOROUS POLISHING ACTION MAY BE NECESSARY.

FIRST TRY A PASTE MADE WITH WATER AND AMMONIA AS THE LIQUID AND EITHER MAGNESIUM
OXIDE, FINELY POWDER PUMICE OR FRENCH CHALK AS THE SOLID. YOU CAN ALSO USE ONE OF
SEVERAL COMMERCIAL CLEANERS LISTED IN THE FOLLOWING TABLE.

RUB AS GENTLY AS POSSIBLE IN THE DIRECTION OF THE POLISHING MARKS ON THE STEEL,
USING A SOFT CLOTH. FOR MORE RESISTANT DEPOSITS, USE A STAINLESS STEEL SCOURING
SPONGE OR STAINLESS STEEL WOOL OF THE FINEST POSSIBLE TEXTURE.

WHAT NOT TO DO:
DO NOT USE COMMON STEEL WOOL, SCOURING PADS, SCRAPERS, WIRE BRUSHES, FILES OR

OTHER STEEL TOOLS, SINCE THESE CAN MAR THE STAINLESS STEEL. THESE PARTICLES WILL
EVENTUALLY RUST AND STAIN THE SURFACE, AND YOU MAY HAVE TO REFINISH IT.

HOW TO CLEAN STAINLESS STEEL

(CONT.)

SLIGHTLY DARKENED AREAS SOMETIMES APPEAR ON STAINLESS STEEL SURFACES WHERE HEAT
HAS BEEN APPLIED DURING FABRICATION OR IN SERVICE.

THESE ARE CAUSED BY THICKENING OF THE PROTECTIVE SURFACE OF STAINLESS STEEL, AND
ARE NOT HARMFUL. REMOVAL CALLS FOR ENERGETIC SCOURING, AGAIN USING A STAINLESS
STEEL WOOL OR SCOURING PAD, COMBINED WITH A SCOURING POWDER OR ONE OF THE HEAT­TINT REMOVERS LISTED IN THE TABLE.

THREE RULES WILL PREVENT HEAT TINTING:

1) USE ONLY ENOUGH HEAT TO DO THE JOB EFFICIENTLY.

2) DO NOT APPLY HEAT TO EMPTY EQUIPMENT.

3) AVOID CONCENTRATING HEAT ON A SMALL AREA.
*** CAUTION IS ADVISED ***

IN STERILIZING STAINLESS STEEL EQUIPMENT, PAY PARTICULAR ATTENTION TO AGENTS
CONTAINING CHLORINE COMPOUNDS SUCH AS POTASSIUM HYPOCHLORITE. THESE COMPOUNDS
MAY BREAK DOWN AND RELEASE FREE CHLORINE, OR HYDROLYZE TO FORM HYDROCHLORIC
ACID.

STAINLESS STEEL RESISTS ATTACK BY SUCH COMPOUNDS FOR UP TO TWO HOURS. SEVERE
LOCALIZED PITTING MAY OCCUR FROM LONGER EXPOSURE. FOR SAFE USE OF THESE AGENTS,
KEEP CONTACT TIME SHORT, FLUSH THOROUGHLY WITH WATER, AND OPERATE EQUIPMENT
NORMALLY BETWEEN APPLICATIONS. USING THESE PRECAUTIONS, THE STERILIZATION
PROCESS CAN BE REPEATED ANY NUMBER OF TIMES.

3. The following detergents and solvents are excellent removers of grease, oil and fatty acids, where
swabbing or rubbing is not practical.

4 to 6% solution of all excellent
(sodium Metasillcate) removers of grease,
(Trisodium Phosphate) oil, and milkstone
(Sodium Metaphosphate)
(Sodium Pyrophosphate)

5-15% caustic soda (hot or cold) will remove grease

4. The following organic solvents may be used for removing oils and grease deposits:
Carbon-tetrachloride, Naphtha, Trichlorethylene No affect on finish,

Acetone, Kerosene, Gasoline, Ether, Alcohol, Benzene however, take all

Notes: ordinary wool or steel brushes should never be used on stainless steel surfaces. Particles of steel
may become imbedded in the stainless steel surface, and rusting of these particles will eventually appear
as stains. Use stainless steel wool or sponge on stainless steel equipment. Heat tint removers will
usually scratch stainless steel surfaces. This, however, is necessary in removing heat tint by hand.
Oakite, a fibrous material, may be used in place of metal sponges or cloth pads for applying cleaners and
polishes. This material is effective in aiding in removal of milkstone.

For heavy hard water deposits, 15-20% (by volume) nitric acid is very effective. Acid treatment should be
followed by a thorough water rinse.

The action of soldering fluxes should be neutralized immediately with a 5% sodium carbonate solution.
Soap and water followed by a water rinse will not harm stainless steel.
