BATTERY CONFIGURATIONS

Batteries of up to four fryers wide can be configured with any HF Series Fryer or HFO Frymate Dump

Station (either 15

/2" [39 cm] or 21" [53 cm ] wide). Possible configurations showing positions A through

E are depicted below:

NOTES:

= Dump Station; = Fryer.

*Indicates filter interplumbing not available. A filter dump station can be located under any position in a battery if it has been built without an HFO Frymate. A filter dump station can be located under any position in a battery if the line-up has been built with an HFO Frymate located at either end of the battery. When a HFO Frymate is built between two fryers within a battery, the filter dump station is located under the HFO Frymate. In two-unit batteries utilizing a HFO Frymate, the filter dump station will always be located under the fryer. All options and accessories can be used with batteried equipment. HFO15 is used on Model HF50. HFO21 is used on Model HF85.

INSTALLATION

Before installing the fryer, verify that the electrical service agrees with the specifications on the fryer data plate which is located on the inside of the door panel. If the supply and equipment requirements do not agree, do not proceed with the installation. Contact your dealer or Hobart Corporation immediately.

UNPACKING

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

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

LOCATION

The fryer may be installed at 0" clearance from the back or side walls. A 16" (40.6 cm) clearance is required between the fryer and any open top flame burner. Position the fryer for easy accessibility for service.

INSTALLATION CODES AND STANDARDS

Your Hobart fryer must be installed in accordance with:

1. State and local codes.

2. The National Electrical Code, ANSI/NFPA No. 70 (latest edition). Copies may be obtained from The National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

3. NFPA Standard #96.

ASSEMBLY

The fryer must be restrained with adequate ties to prevent tipping when installed in order to avoid the splashing of hot liquid.

Legs

Position fryer in an open space near the final installation area. Tilt fryer on its side, being careful to avoid scratching the finish. Thread legs into mounting holes provided on bottom of fryer by screwing in a clockwise rotation until tight.

Carefully raise fryer to its normal position and place it in the installing location.

Casters (Optional)

It is recommended that casters be installed on all batteried appliances. A strain relief (Fig. 1) is supplied to protect the electrical supply line.

If it is necessary to disconnect the restraint, unplug electrical supply before disconnection. Reconnect the restraint before plugging the electrical supply in and returning the fryer to its installation position.

Instructions for installing casters to the fryer are included with the casters.

STRAIN RELIEF FITTING FOR ELECTRIC THIS SIDE ONLY.

(Strain relief fitting supplied by Hobart. Chain to be supplied by others.)

PL-53296

Fig. 1

LEVELING

Place a carpenter's level on top of the fryer and level the fryer front-to-back and side-to-side by turning the adjustable legs or casters.

ELECTRICAL CONNECTIONS

WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE NATIONAL

ELECTRICAL CODE AND/OR OTHER LOCAL CODES.

WARNING: DISCONNECT THE ELECTRICAL POWER SUPPLY TO THE MACHINE AND FOLLOW LOCKOUT/TAGOUT PROCEDURES.

WARNING: APPLIANCES EQUIPPED WITH A 120V FLEXIBLE ELECTRIC SUPPLY CORD ARE PROVIDED 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.

Place fryer as near to its final position as possible. Connect 3 phase line to X, Y and Z of terminal block. To reach terminal block, remove electric cover plate from fryer.

For each 15

/2" (39 cm) and 21" (53 cm) section, a 3 phase supply line capable of handling the required KW at the fryer's rated voltage (208, 240, 480) is needed. Refer to the fryer data plate for this electrical information.

If a fan interlock is needed, it should be connected to 1 and 2 on the 4 pole barrier strip. 1 and 2 go to a set of dry contacts on the power switch.

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 and Heating Elements

Do not operate fryer without frying compound or water solution in the tank.

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. Rinse thoroughly and drain by opening the drain valve (accessible when the door is opened). After cooling, wipe tank and heating elements completely dry with a soft clean cloth. (See also CLEANING — WEEKLY in this manual.) NOTE: When cleaning, avoid moving the thermostat bulb or capilary.

Clean all fryer accessories. Rinse all parts thoroughly after cleaning and wipe dry.

FILLING THE FRY TANK WITH SHORTENING

Liquid shortening may be used in all HFD/HFC Series Fryers.

Melting solid shortening without using the melt cycle will damage the heating elements 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. On HFC fryers, the computer must be programmed for MELT ENABLE.

Fill fryer tank to the fill level line on back wall (Fig. 2). Keep shortening at the fill level line in the fry tank. Add fresh shortening as needed. Do not overfill tank.

ADDING SOLID SHORTENING

If replacing shortening, place the block of shortening in the room with the fryer for 1 to 2 hours before using. This will soften the shortening and make it easier to divide.

CAUTION: Failure to remove crumb screens prior to addition of fresh shortening may cause heating elements to overheat, allowing shortening to reach flashpoint.

After draining shortening, allow the tank to cool down before adding all new shortening to avoid scorching new shortening.

Shortening Capacity

Full Vat 50 lb., 85 lb. (22.7, 38.5 kg)

WARNING: Do not set a complete block of solid shortening on top of an electric fryer's heating elements. Doing this may damage the elements and increase the potential for shortening flash fire. If solid shortening is to be used in an electric fryer, remove the baskets and crumb screen(s), raise elements from tank, pack the bottom of the tank completely with solid shortening, lower the elements and then pack the shortening COMPLETELY around over top of the elements. Lay crumb screen(s) in the tank on top of the packed shortening. Follow the Fat Melt instructions in the installation & operation manual. Once all shortening has been melted and the fryer has met the set temperature, fill baskets and resume frying.

Single Vat

1. Remove crumb screens from fryer tank.

2. Lift elements out of each tank area.

3. Chop the solid block of shortening into pieces that can be packed into the bottom of fryer tank.

4. Pack bottom of the tank with shortening chunks.

5. Lower elements back into tank.

6. Pack the remaining chunks of shortening completely around and over top of the elements, then place the screen on top of the shortening.

DAILY SHORTENING ADDITION (All Models)

Add approximately 15% new shortening daily. Keep level of shortening at fill level line in fry tank. Add fresh shortening as needed.

HIGH LIMIT CONTROL

If the shortening becomes overheated, one of the temperature shutoff devices will shut the fryer off. DO NOT turn fryer on until the shortening temperature is below 300°F (149°C).

If the high limit device has shut the fryer system off, push the red reset button on the back of the element head(s) before turning the fryer back on.

If this situation persists, shut fryer down and contact your local Hobart service office.
