Installation, Operation and Care of

MODEL HP15G & HP15GF GAS PRESSURE FRYERS

SAVE THESE INSTRUCTIONS FOR FUTURE USE

GENERAL

Your Hobart Gas Pressure Fryer will produce uniform, high quality product time after time. It operates at a low temperature (325°F) and high pressure (14 psi). Rapid cooking time increases production and improves energy efficiency, and high pressure frying preserves food flavor and reduces shrinkage. Up to 15 pounds of product may be prepared at a time.

Standard equipment includes a drain pipe extension for the exhaust tank, wooden doughnut stick, 11/4" exhaust pipe, solenoid open wrench, insulated mitts, and a flexible cleaning rod. Both legs and casters are supplied with each fryer. Extra O-ring seals for the lid, the kettle pressure regulator assembly and the cleaning port plug screw are also included. The O-ring seals are not covered under normal warranty.

Model HOF40 Filtering System for draining and filtering the oil for Model HP15G is available as an option.

IMPORTANT: Your pressure fryer must be cleaned frequently or it will not function properly. Follow the procedures in the CLEANING section of this manual.

INSTALLATION

When installing this pressure fryer, the base should remain open at the front to allow air circulation for the gas burner. DO NOT BLOCK THE FRONT OF THE FRYER.

Prior to installation, verify that the electrical and gas supply lines agree with the specifications on the fryer data plate, which is located on the inside of the door.

UNPACKING

Immediately after unpacking the pressure fryer, check it for possible shipping damage. If this fryer is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

Do not use the door to lift or move the fryer.

– 4 –

LOCATION

The equipment area must be kept free and clear of combustible substances. The pressure fryer, when installed, must have minimum clearance from combustible and non-combustible

construction of 1" at the sides and 3" at the rear of the fryer. This fryer is for use on non-combustible floors only. It must be installed at least 12" away from open top flame units.

The installation location must allow adequate clearances for servicing and proper operation. The pressure fryer must be installed so that the flow of combustion and ventilation air will not be obstructed.

Adequate clearance for air openings into the combustion chamber must be provided. Make sure there is an adequate supply of air in the room to allow for combustion of the gas at the fryer burners.

Do not permit fans to blow directly at the pressure fryer. Wherever possible, avoid open windows next to the pressure fryer. Avoid wall-type fans which create air cross currents within the room.

INSTALLATION CODES AND STANDARDS

Hobart pressure fryers must be installed in accordance with:

In the United States

1. State and local codes.

2. National Fuel Gas Code, ANSI-Z223.1 (latest edition), available from The American Gas Association, Inc., 1515 Wilson Blvd., Arlington, VA 22209.

3. National Electrical Code ANSI/NFPA-70 (latest edition).

Casters

Place the fryer on its side, being careful to avoid scratching the surface. Use only the casters supplied with your pressure fryer.

Thread the 4 casters to the flanges on the bottom corners of the fryer. Use the open-ended wrench supplied to tighten (apply wrench at the flat surfaces on leg extensions). The 2 locking casters mount at the front; the nonlocking casters at the rear.

Tighten At Flats

PL-51559

Fig. 1

For pressure fryers equipped with casters, the installation shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 (latest edition) and CGA 6.16 (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) and CAN1-6-9 (latest edition).

Provide a restraining device for the gas line to limit movement of the fryer without depending on the connector and any quick-disconnect device or its associated piping to limit fryer movement. Attach the restraint to the rear of the fryer (Fig. 2).

If disconnection of the restraint is necessary, turn off the gas supply before disconnection. Reconnect this restraint before turning the gas supply on and returning the pressure fryer to its original installation position.

GAS CONNECTIONS

All gas supply connections and any pipe joint compound used must be resistant to the action of liquified petroleum gases.

Location of the gas inlet is underneath the fryer on the left-hand side toward the rear. Pipe gas supply to the fryer. Make sure the pipes are clean and free of obstructions, dirt, and piping compound. Codes require that a gas shutoff valve be installed in the gas line ahead of the pressure fryer. The orifices are set at 3.5" W.C. (Water Column) pressure for natural gas, and 11" W.C. (Water Column) pressure

for propane gas. A manifold pressure regulator is supplied as part of the gas control valve. No adjustment should be required.

WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.

After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air. Make certain primary air supply to the main burner is properly adjusted for complete combustion.

TESTING THE GAS SUPPLY 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 manual shutoff valve.

FLUE CONNECTIONS

This pressure fryer must be installed under a ventilating hood. From the termination of the fryer flue vent to the filters of the hood venting system, a minimum clearance of 18" must be maintained.

Do not obstruct the flow of flue gases from the flue duct located on the rear of the fryer. It is recommended that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel.

Information on the construction and installation of ventilating hoods may be obtained from the standard for "Vapor Removal from Cooking Equipment," NFPA No. 96 (latest edition).

ELECTRICAL CONNECTIONS WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE APPLICABLE

PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL ELECTRICAL CODES. WARNING:

WITH

A THREE-PRONG GROUNDING PLUG. IT IS IMPERATIVE THAT THIS PLUG BE CONNECTED INTO A PROPERLY GROUNDED THREE-PRONG RECEPTACLE. IF THE RECEPTACLE IS NOT THE PROPER GROUNDING TYPE, CONTACT AN ELECTRICIAN. DO NOT REMOVE THE GROUNDING PRONG FROM THIS PLUG.
