Melt Options (GRD Series)
When using solid shortening in the fryer, the CY S (solid shortening) option must be used. Solid
shortening must be gently warmed to a liquid state before heating to frying temperatures. Melting solid
shortening without using this option will damage the fry tank and scorch the shortening.
The controller has three options for bring shortening up to temperature:
CY L (Liquid shortening) - For slowly bringing liquid shortening up to temperature.
CY S (Solid shortening) - For slowly melting solid shortening.
CY O (No melt) - For immediately bringing liquid shortening up to fry temperature.
Upon startup, if the CY L or CY S melt option is selected and the shortening temperature is below 135°F
(57°C), CY is displayed in the window and the fryer cycles to bring the shortening up to temperature.
If the shortening temperature is over 135°F (57°C), HEAT is displayed in the window and the fryer
quickly heats up to set temperature.
The temperature is displayed in the window when the fryer has reached the set temperature. After the
first initial startup, the fryer always defaults to the last entered melt option.

Melt Options (GRC Series)
When using solid shortening in the fryer, the SOLID melt option must be used. Solid shortening must
be gently warmed to a liquid state before heating to frying temperatures. Melting solid shortening
without using this option will damage the fry tank and scorch the shortening.
The controller has three options for bring shortening up to temperature. Upon startup, the fryer will
display the selected melt option in the window when heating:
HEATING
MELT L
MELT S
NO MELT - For immediately bringing shortening up to fry temperature.
LIQUID - For slowly bringing liquid shortening up to temperature.
SOLID - For slowly melting solid shortening.
If the LIQUID or SOLID melt option is selected and the shortening temperature is below 135°F (57°C),
MELT L or MELT S is displayed in the window and the fryer cycles to bring the shortening up to
temperature. If the shortening temperature is over 135°F (57°C), HEATING is displayed in the window
and the fryer quickly heats up to set temperature.
The temperature is displayed in the window when the fryer has reached the set temperature. After the
first initial startup, the fryer always defaults to the last entered melt option.
Filter
The Filter parameter can be programed to alert the operator to filter the shortening by counting the
number of cook counts. When the actual cook count is the same as the programmed cook count,
FILTER flashes in the window. It also can be programmed to time the filtering process.
• PROG 0000 - Enter the number of cook counts you want the controller to count before giving
a filter alert (each time a timer times out is equal to one cook count). To disable the filter
reminder, enter 9999.
• ACT 0000 - Leave at 0000 unless editing. This is the number of cook counts.
• TIME 00:00 - Enter the amount of time for timing the filtering process. Leave at zero if you do
not wish to use the timer.
• Pressing either arrow on
starts the filter timer after the drain valve is opened.
• After the timer times out, FILTER DONE is displayed in the window and a beeper sounds for
5 seconds. The filter prompt and cook count are reset to zero. After the beeper stops, CLOSE
DRAIN is displayed in the window (see Daily Filtering on page 31 for more information).
Dispose
The controller can also be programmed to alert the operator to dispose of the shortening by counting
the number of times the shortening is filtered. When the filter count is the same as the programmed filter
count, DISPOSE is displayed in the window.
• PROG 00 - Enter the number of filter counts you want the controller to count before giving a
dispose alert. To disable the dispose reminder, enter 99.
• ACT 00 - Leave at 00 unless editing. This is the number of times the shortening has been filtered.

DAILY FILTERING
WARNING: HOT OIL AND PARTS CAN CAUSE BURNS. USE CARE WHEN OPERATING,
CLEANING AND SERVICING THE FRYER.
Filtering Guidelines (All Models)
• Stand alone fryers are available in filter-ready and non-filter-ready versions.
• Battery interplumbing is available only on fryers equipped with KleenScreen.
• A cold fryer will not drain properly. Always filter shortening in a liquid state. The shortening under
the cold zone area will remain hard, even if the heat is on for a few minutes. If necessary, use
the cleanout rod to carefully stir the hard shortening to an area above the cold zone (Fig. 8)
where it will melt.
• Filter shortening at least once a day (see Shortening Life on page 33).
Fig. 8
Filter-Ready Fryers (For Use With Mobile Filter Only)
• The Mobile Filter is covered in a separate instruction manual. Follow the instructions.

Battery Interplumbing (Only Available on KleenScreen Models)
A battery of fryers equipped with optional interplumbing connects the fry tanks to a common drain.
Each tank has an individual drain valve. Only one tank can be filtered at a time. Instructions for the
KleenScreen filtering system are covered in a separate manual. Follow the instructions.
Filtering Procedures (Non-Filter-Ready Fryers)
1. Shut down the fryer.
2. Slowly remove basket(s).
3. Open fryer door and attach the drain pipe to the drain valve.
4. Select a container that will hold all the liquified shortening and place it below the drain pipe.
5. If using a filter bag, tie it securely to the drain pipe. If a different filter medium is used, place it
in the container.
6. Open drain valve carefully so the oil stream is directed through the filter. See Filtering
Guidelines on page 31 for draining tips.
7. Flush out scraps and sediment in the fry tank with a small amount of warm shortening.
8. Drain the tank thoroughly and wipe clean.
9. Should it be necessary to clean the tank more thoroughly, see Cleaning on page 33.
10. Close the drain valve.
11. Pour the filtered shortening back into the fry tank.
12. Shortening level should be between the MIN and MAX lines.
HIGH LIMIT DEVICE (All Models)
If the shortening becomes overheated, a high-temperature device will close the gas valve and
extinguish the pilot. Should this occur, the pilot will be unable to relight until the shortening temperature
is below 300°F (149°C). If the temperature is below 300°F (149°C) and the pilot will not relight, contact
your local Vulcan-Hart Service office.
DRAIN INTERLOCK (GRD and GRC Series)
Prevents the burners from operating when the drain valve is open.
SHORTENING LIFE (All Models)
Shortening life can be extended by following these guidelines:
• Do not salt foods over the fryer.
• Use good quality shortening.
• Filter shortening daily (at a minimum).
• Replace shortening if it becomes poorly flavored.
• Keep equipment and surroundings clean.
• Remove excess moisture and particles from food products before placing in fryer.
