Battery Interplumbing (Optional)
A battery of fryers equipped with optional interplumbing connects the fry tanks to a common drain. Each
tank has an individual drain valve; these should only be opened one at a time.
Always be sure you have adequate container capacity before opening drain; monitor draining process.
After oil has filtered into the mobile filter, it is pumped back to the individual tank by (1) closing the drain
valve, and (2) opening the valve on the return line (Fig. 4). Only one return valve should be opened at any
one time.
After oil is pumped back, close the return valve. Fill tank to the fill level line on the back wall of the fry tank.

SHORTENING LIFE
Shortening life may 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.
• Set thermostats correctly.
• Remove excess moisture and particles from food products before placing in fryer.
HIGH LIMIT DEVICE
If the shortening becomes overheated, a high temperature shutoff device will turn the gas valve off and
extinguish the pilot. DO NOT relight the pilot until the shortening temperature is below 300°F (149°C). If
this situation persists, contact your local Vulcan-Hart authorized service office.
