INSTALLATION AND OPERATION MANUAL FOR GRC SERIES GAS FRYERS KEEP THESE INSTRUCTIONS FOR FUTURE USE GENERAL Vulcan-Hart GRC Series Gas Fryers are available in 4 sizes with an array of features and options for a range of commercial fryer applications. While the overall tank widths on the GRC35 and GRC45 are the same, the GRC45 has a deeper tank area than the GRC35. Thus the GRC45 has larger tank capacity than GRC35 but not as large as GRC65.

INSTALLATION Before installing the fryer, verify that the type of gas (natural or propane) agrees with the specifications on the fryer data plate which is located on the inside of the door panel. Also be sure the unit is built for the installation elevation. UNCRATING This fryer was carefully inspected before leaving the factory. The transportation company assumes full responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking the fryer, check for possible shipping damage.
Carefully raise fryer to its normal position and place it in installing location. Casters (Optional) It is recommended that casters be installed on all batteried appliances. If the fryer is equipped with casters the gas connector (available from Vulcan-Hart) must comply with the Standard for Connectors of Movable Gas Appliances, ANSI-Z21.69 (latest edition), and a quick-disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI-Z21.41 (latest edition).
TESTING THE GAS SUPPLY PIPING SYSTEM When test pressures exceed 1⁄2 psig (3.45 kPa), the fryer and its individual shutoff valve must be disconnected from the gas supply piping system. When test pressures are 1⁄2 psig (3.45 kPa) or less, the fryer must be isolated from the gas supply piping system by closing its individual shutoff valve. LEVELING THE FRYER Once gas connections have been made, place a spirit level on top of the fryer.
OPERATION WARNING: HOT OIL AND PARTS CAN CAUSE BURNS. USE CARE WHEN OPERATING, CLEANING AND SERVICING THE FRYER. WARNING: SPILLING HOT FRYING COMPOUND CAN CAUSE SEVERE BURNS. DO NOT MOVE FRYER WITHOUT DRAINING ALL FRYING COMPOUND FROM THE TANK. BEFORE FIRST USE Clean the Fryer Using a non-corrosive, grease-dissolving commercial cleaner, clean the protective metal oils from all surface parts and the tank interior. Follow the cleaner manufacturer's directions.
MELTING SOLID SHORTENING Melting solid shortening without using the melt cycle will damage the fry tank and scorch the shortening. Only fryers equipped with the MELT cycle may use solid shortening. Solid shortening must be gently warmed to the liquid state before heating to frying temperatures. To begin the melt cycle, press the MELT switch. ELECTRONIC IGNITER CAUTION: Before turning the burners on, the fry tank must be filled with liquid or melted shortening.
FRYING Heat shortening to set temperature. Pieces of product to be fried should be about the same size to ensure the same doneness. Drain or wipe dry raw or wet foods to minimize splatter when lowering into the hot oil. Do not overfill baskets. Recommended maximum capacities are: Models Lb / kg of Total Lb / kg Total Lb / kg Product of Product of Product (1 Basket) (2 Baskets) (3 Baskets) GRC35 11/2 / 0.6 3 / 1.4 N/A GRC45 21/2 / 1.1 5 / 2.3 N/A GRC65 3 / 1.4 6 / 2.7 9 / 4.1 GRC85 31/2 / 1.
DAILY FILTERING Fryers Without Filter Ready Options Turn gas valve off when draining or filling. Always filter the shortening while liquified. A cold fryer will not drain properly because the shortening under the cold zone tube area will remain hard, even if the heat is on for a few minutes. If necessary, the cleanout rod may be used to carefully stir up hard fat to an area above the cold zone (see Fig. 2) where it will melt. After the cold zone is liquified, turn the fryer thermostat and gas valve off.
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).
