GENERAL INFORMATION
This equipment is designed and sold for commercial use only by personnel trained and experienced
in its operation and is not sold for consumer use in and around the home nor for use directly by the
general public in food service locations. For equipment to be used by the general public, please
contact the factory.
INSTALLATION
The griddles are equipped for the voltage indicated on the nameplate mounted on the front panel.
They will operate on alternating current (AC) only.
WARNING
DO NOT CONNECT TO DIRECT CURRENT (DC).
The installation of the electric griddle should conform to the:
NATIONAL ELECTRIC CODE AND ALL LOCAL ELECTRIC CODES AND
ORDINANCES AND THE LOCAL ELECTRIC COMPANY RULES AND
REGULATIONS
For your protection we recommend that a qualied electrician install this griddle. He should be
familiar with electrical installations and all electric codes. Proper connections and power supply are
essential for efcient performance. The external wiring should be in conduit or an approved type
of exible cable suitable for operation at the temperature indicated on the wiring diagram, and of a
proper size to carry the load. The supply circuit should be properly fused and equipped with a means
of disconnecting, as required by local electrical code. THE BODY OF THE GRIDDLE SHOULD BE
GROUNDED (DO NOT GROUND TO A GAS SUPPLY LINE).
EXHAUST CANOPY
Griddles inherently create a good deal of heat and smoke and should be installed under an efcient
exhaust hood with ame proof lters. A vertical distance of not less than 48” shall be provided
between the top of the appliance and lters or any other combustible material. Exhaust installation
must conform to local codes.
AIR SUPPLY: Provisions for adequate air supply must be provided.
GENERAL OPERATING PROCEDURES
The Ultra-Max series electric griddles may be wired for operation in the eld for either 1-phase or
3-phase power supplies by making line connections at the junction box(es) located at the rear of the
unit. Models 724T-230/400V, 736T-230/400V & 748T-230/400V, should be wired for 3-phase power
supply only. Two junction boxes are provided on the 760T & 772T for making line connections.
CONNECTING POWER SUPPLY
Detach cover on junction box at rear of unit. There is a terminal block for the supply connection in the
junction box. Wires can be rerouted in the terminal block for 3phase hook-up. See wiring diagrams
and model voltage on unit panel
LOCATING AND LEVELING THE UNIT
Do not install the unit closer than 1-inch from a side wall and/or closer than 1-inch from a rear
wall. Make sure the unit is properly ventilated. Level unit by adjusting the (4) feet which have an
adjustment of 1-3/4” (43.75mm) for accurate leveling and perfect line-up with other Ultra-Max series
units.

GENERAL OPERATING PROCEDURES continued
SEASONING THE GRIDDLE HEATING SURFACE
Before initial use, clean the griddle surface thoroughly with hot soap and water. See Griddle care on
page 4 for further information. After the griddle has been thoroughly cleaned, it should be seasoned
to prevent food from sticking. Before using and after each thorough scouring, season the griddle
heating surface in the following manner.
1. Remove any shipping material from the cooking surface and thouroughly clean the entire grill
with hot soap and water.
2. Turn temperature control dials to 350°F (177°C).
3. Using a clean cloth, not a spatula, brush a thin lm of cooking oil over the griddle cooking surface.
This lm should remain on the hot griddle surface for half an hour.
4. Remove the excess oil and wipe clean.
5. Apply another lm of cooking oil over the hot cooking area for another half hour and again
remove excess oil and wipe clean. The griddle surface should now be ready for use.
Even with careful seasoning, food may, to some extent, stick to the griddle cooking surface until the
griddle plate is broken in.
TEMPERATURE CONTROL
The temperature controls are combination “ON/OFF” switches and thermostats. Turning the dial knob
automatically maintains the selected heat range.
The Ultra-Max electric griddle line has one thermostat for every 12” (30cm) section of griddle that
operates independently of one another. Each thermostat controls the section of the griddle above it
and may be set at different temperatures as desired.
COOKING
Set the thermostat dial knob at the temperature desired. After a short pre-heating period, the
thermostat will automatically maintain the selected temperature.
IDLING
During idle periods, to save on operating costs, lower the temperature setting of the thermostat to
about 250°F (121°C). It is not necessary to maintain cooking temperature during idle periods, as the
griddle can quickly be reheated to the desired temperature.
SIGNAL LIGHTS
Each thermostat has its own signal light which indicates when the unit’s control knob is in the on
position. Cooking surface will be hot when the control knob is in this position.

CAUTION
CLEANING
GRIDDLE CARE (NON-CHROME SURFACES)
It takes very little time and effort to keep the griddle attractive and performing at top efciency
If grease is permitted to accumulate, it will form a gummy cake and then carbonize into a hard
substance which is extremely difcult to remove. To prevent this condition, the following suggestions
for cleanliness should be followed:
1. After each use, scrape the griddle with a scraper or exible spatula to remove excess grease
and food. A waste drawer is provided for the drippings. If there is an accumulation of burned
on grease and food, the griddle should be thoroughly scoured and re-seasoned. Use pumice
or griddle stone while the griddle is warm. Do not use steel wool because of the danger of steel
slivers getting into the food.
2. Daily, use a clean cloth and a good non-abrasive cleaner to clean the stainless steel body of
the griddle. Wipe the polished front with a soft cloth.
3. At least once a day, remove the waste drawer and wash in the same way as an ordinary cooking
utensil. The drawers are removed by pulling forward until they are released from their track.
.
GRIDDLE CARE (CHROME SURFACES)
(Chrome surface griddles are marked with “CHS” at the end of the model number designation on the
nameplate.) It takes very little time and effort to keep this Industrial Chrome griddle surface sparkling
clean and performing at top efciency. DO NOT allow grease to accumulate as it will carbonize and
become difcult to remove. To prevent this condition, the following cleaning suggestions should be
followed:
1. Remove excess oil and food regularly with a 4” (100mm) wide razor sharp type scraper and
wipe surface with a damp cloth if desired.
2. Following the scraping, for end of the day cleaning, a damp cloth and a non-silicated, non-
abrasive, non-chlorinated cleaner such as Bon-Ami may be used to wipe surface clean, followed
by wiping with clean wet cloth.
3. Follow steps 2 and 3 from Griddle Care (Non-Chrome Surfaces).
ON C
HROME SURFACES:
1. Never use pumice, griddle stones, or abrasives on the surface.
2. Never strike the griddle surface with a sharp instrument or spatula edge.
3. Never use steel wool.
4. Never use commercial liquid grill cleaner on the griddle surface.
5. Abusing the surface voids the warranty.
GREASE DRAWER
A grease drawer is located at the front can be removed for cleaning by pulling drawer forward. This
drawer contains hot grease and should be checked and emptied when necessary or at least once a
day.
EXERCISE EXTREME CARE IN HANDLING THE GREASE DRAWER
CAUTION
CONTAINING HOT GREASE.
Never pour large amounts of water onto a hot griddle surface, the sudden
