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. Ensure the fryer is configured for the proper elevation. UNPACKING 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.
LOCATION The equipment area must be kept free and clear of combustible substances. Minimum clearance from combustible construction is 6" (15 cm) from the sides and 6" (15 cm) from the back of the fryer. Minimum clearance from noncombustible construction is 0" from the sides and 0" from the back. At least 16" (41 cm) clearance must be between the fryer and any open-top flame units. Adequate clearances for servicing and proper operation must be allowed. The fryer may be installed on combustible floors.
ASSEMBLY When installed, the fryer must be restrained to prevent tipping in to avoid the splashing of hot liquid. The means of restraint may be the manner of installation, such as connection to a battery of appliances or installing the fryer in an alcove, or by separate means, such as adequate ties. Fryers Mounted on Legs (Non-Batteried Fryers) Fryers serviced from the rear must have a minimum clearance of 18" (46 cm) from the wall when mounted on legs. 1.
GAS CONNECTIONS CAUTION: All gas supply connections and any pipe joint compound must be resistant to the action of propane gases. The gas inlet is located on the lower right rear of the fryer. Codes require that a gas shutoff valve be installed in the gas line ahead of the fryer. The gas supply line must be at least the equivalent of 1/2" iron pipe for single units and 1 1/4" for batteries. If using the optional quick-disconnect flex hose: 3/4" iron pipe for single units and 1 1/4" iron pipe for batteries.
LEVELING FRYER 1. Place a spirit level on top of the fryer after gas connections have been made. 2. Adjust the legs to ensure that the fryer is level front-to-back and side-to side in the final installed position. FLUE CONNECTIONS The fryer must be located under a hood with adequate connection to an exhaust duct. The hood must extend 6" (15 cm) beyond fryer sides.
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 protective metal oils from all surface parts and the tank interior using a noncorrosive, grease-dissolving commercial cleaner. Follow the cleaner manufacturer's directions.

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.

FRYING GUIDELINES (All Models) • Heat shortening to set temperature. • Fry pieces of product that are about the same size together. • Drain or wipe dry raw or wet foods to minimize splatter when lowering into the hot shortening. • Keep shortening between the MIN and MAX lines. Shortening will expand when heated; do not fill the fry tank past the MAX line. • Add fresh shortening as needed. Fry Basket Guidelines • Shake the basket gently to avoid splattering the shortening.
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.
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.
CLEANING WARNING: HOT OIL AND PARTS CAN CAUSE BURNS. USE CARE WHEN OPERATING, CLEANING AND SERVICING THE FRYER. DAILY • Clean all exterior surfaces of your fryer at least once daily. • Use a damp cloth with warm water and a mild soap or detergent. • Rinse thoroughly, then polish with a soft, dry cloth. • Keep the fryer exterior clean and free of accumulated grease to prevent stubborn stains from forming. If regular cleaning is neglected, grease will be burned on and discolorations may form.
10. Drain the tank. 11. Rinse the tank thoroughly with clear, hot water (all traces of cleaner must be removed). 12. Dry the tank thoroughly. 13. Close the drain valve and add shortening. 14. Shortening level should be between the MIN and MAX lines. Shortening will expand when heated; do not fill the fry tank past the MAX line. The fryer is now ready for use. MAINTENANCE WARNING: HOT OIL AND PARTS CAN CAUSE BURNS. USE CARE WHEN OPERATING, CLEANING AND SERVICING THE FRYER.
TROUBLESHOOTING GUIDE SYMPTOM POSSIBLE CAUSES No power when switch is turned on. Tripped external breaker; external fuse blown. Verify fryer is plugged in and/or check external circuit breakers and/or fuse. Problem with power switch; call service. Problem with high limit; call service. Fryer will not heat. Gas supply not on or partially on. Verify external gas supply valve is on. Check hose connection (if applicable). Power not on. Verify power is on. Gas valve in fryer not on.
