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.
