Fig 6
NOTE: WALDORF 'FAST-FRI' fryers can be used with both oil and shortening.
1. Before filling the tank, always check that the drain valve(s) behind the door is (are) closed. A locking slide is provided on these valves and this should always be locked in position during use.
a. OIL - Carefully fill fryer tank with oil until the 'FILL-LEVEL' mark is reached.
The FN8120G fryer will hold 20 litres of oil (37 lbs shortening). The FN8226G fryer will hold 13 litres of oil per tank (24 lbs shortening per tank). The FN8130G fryer will hold 31 litres of oil. (46.5 lbs shortening).
b. SHORTENING - Ideally shortening should be pre-melted prior to putting it into the tank. This is
normally done in a suitable vessel on a boiling table burner(s). The liquefied shortening can then be poured into the tank until it reaches the 'FILL LEVEL' mark.
When pre-melting shortening, only heat until the shortening is just liquefied. Do not bring up to high temperature as handling of hot shortening is dangerous.
If pre-melting of shortening is not possible then the shortening should be cut in pieces and packed down into the tank.
Bringing the shortening up to frying temperature, when not pre-melting, should be done in two stages.
14
Page 17
Operation
i. Pre-Heating;
Light the main burners and manually cycle the burners ‘On’ / ‘Off’ until the shortening has liquefied. Ideally the main burners should be cycled ‘On’ for 5 seconds and ‘Off’ for 10 seconds. Following this procedure should allow shortening to liquefy gradually without scorching.
ii. Once the shortening has liquefied, it can be brought up to fryer operating temperature.
NOTE: Running burners continuously will cause shortening in contact with the tank to overheat,
resulting in premature oil breakdown. Never allow the shortening to smoke while melting as this indicates that the temperature is too high. If the shortening starts smoking, increase the ‘Off' intervals of the main burners.
Lighting the Pilot Burners
FN8120 Fryer (Single Tank)
1. With the fryer tank full of frying medium, the pilot burners can be lit.
2. Check that the gas supply is turned on at the mains supply.
3. Open the access door at the front of the appliance to access the control panel.
4. Rotate the gas control knob to the position marked 'PILOT' and hold depressed.

15
Page 18
Operation
Lighting the Main Burners
1. Ensure that the pilot burners are alight, by opening the front access door of the appliance and checking that both pilot flames are alight.
2. Depress and rotate the gas control knob to the ‘Full Flame’ position.
3. The main burners will now ignite automatically off the pilot burners.
NOTE:
If the main burners are turned on immediately after the pilot burners are lit, a delay of approximately 30 seconds will occur until the thermopile (which provides power to open the main valve) has heated up off the pilot burners.
The main burners will not light if the frying medium temperature is above the thermostat set temperature.
Turning the gas control knob from the ‘Pilot’ position to the ‘Main Burner’ position will allow manual cycling of the burners ‘On’ and ‘Off’ when melting shortening.
Turning ‘OFF’ the Fryer
To the ‘Pilot’ Position
a. Depress and rotate the gas control valve clockwise to the ‘Pilot’ position. b. The main burners will extinguish and the ‘Pilot’ will remain alight.
To the ‘Off’ Position
a. Depress and rotate the gas control valve fully clockwise to the ‘Off’ position. b. The ‘Pilot’ burners will extinguish. c. Rotate the thermostat to the ‘O’ position.
Setting the Operating Temperature
1. Rotate the gas control knob to the required temperature.
2. The temperature used for frying food is the most important aspect of fryer operation. Incorrect temperatures will result in poor product quality and will reduce the life of the oil / shortening.
3. WALDORF 'FAST-FRI' fryers feature a thermostat which is accurate to 1°C.
4. The temperature can be set from 145°C to 195°C, although we do not recommend any food to be cooked above 190°C.
5. To set the operating temperature simply turn the thermostat to the desired setting.
6. Main burners will operate automatically to maintain this temperature.
7. In order to obtain the best results with your fryer and the product cooked in it, the following pages detail recommended temperatures and a practical guide to frying. Time spent reading this information will assist in obtaining a cooked product of exceptional quality and taste.
8. As a safety precaution all WALDORF 'FAST-FRI' fryers feature an Over-Heat control which will ‘Turn Off’ the fryer in the event that the oil reaches over 220°C, should there be a thermostat failure.
9. WALDORF FN8226G 'FAST-FRI' Fryers feature a split tank allowing distinctive products to be cooked in individual pans and at different temperatures. This allows seafood products to be fried separate from French Fries for instance to stop flavour contamination between products and allow products to be cooked at their optimum frying temperature.
Should any abnormal operation like;
- ignition problems,

Operation
Frying Guide and Care of Frying Oils and Fats.
1. Prepare the food correctly. Prepare the food in as nearly uniform pieces as possible and bring the food up to room temperature. Ensure that the food is free from excessive moisture and also excessive crumbing when 'breading' is done.
2. Preheat the frying medium to the recommended temperature for the particular food to be cooked and no higher - specially prepared frying mediums are recommended.
3. The frying medium should be at the correct temperature for the food to be cooked before lowering the food into the tank. Avoid heating the frying medium to any higher temperature than is recommended. Also avoid holding the frying medium at the frying temperature when there is no food being cooked.
temperatures
4. Lower food gradually into the hot frying medium using a wire basket, until all food pieces are submerged. Avoid overloading the basket, we recommend no more that 900g per basket or 1800g per load.
.
Overloading will cause temperature to drop so low that a longer frying time will be needed
and the foods will become grease soaked and unattractive
amount of food may be added to fryer without causing excessive drop in temperature. If the temperature drop is excessive, either the food is too cold or there is too much food in fryer. Temperatures and cooking times quoted are based on average size batches being used in fryer.
5. Continue cooking until the outside of the food is brown and crisp and the pieces are cooked through.
6. The exact cooking time depends upon the size of the food pieces and upon whether the food has been pre-cooked. When in doubt, test a sample and be sure.
7. Remove the food from the frying medium and allow the food to drain in the basket over the fryer.
8. Conserve the excess frying medium by letting it drain back into the fryer. This draining should not consume much time if the fried food is to be served at its hot, crisp and flavoursome best.
9. Serve the food immediately after frying.
10. Deep fried foods are at their flavour peak as soon as the frying is complete. Serve them within a minute or two after they are taken from the fryer.
Frying Temperature Guide and Care of Frying Medium
Any frying medium will break down if held for long periods at frying
. With experience you can determine what
Fried foods should never be held.
Summary of Practical Care of Frying Fats and Oils
Fats and oils are unstable compounds. Even the best oils and fats will break down to some extent in the fryer.
There are a number of causes of frying mediums ceasing to be edible. Heat and moisture are two of the most important causes and we have both heat and moisture in the deep well fryer.
Frying medium is by far the most expensive item of deep well frying equipment, if the following points are carefully observed, the cost of frying can be kept to a minimum:-
a. Select one of the recommend mediums for deep frying (Hydrogenated shortening, high grade
lards or salad oils made from peanuts, cottonseed or corn). Know the smoking temperature of the one you select, generally the heat temperate qualities and stability of frying oils, particularly peanut oil, are perhaps greater than that of the solid fats.
b. Avoid burning the medium - either when putting new medium into fryer or during frying,
food needs a deep well frying temperature higher than 195°C and most foods should be fried around 180°C
c. Have rapid 'turnover' of the frying medium. The term 'turnover' means the rate at which fresh
medium is added to the old medium in the fryer.
d. Filter the frying medium daily, or more often if necessary, to remove crumbs and other
sediment.
e. Clean fryer each time the medium is filtered, to keep it free from gum. Also be sure that all
soap and detergent is thoroughly removed from the fryer after cleaning it.
f. Taste the frying medium daily to be sure there is no 'Off' flavour which may be transmitted to
other foods.
If these simple precautions are taken consistently, fried foods can always be served at their delicious best. Furthermore, the breakdown of frying medium can be kept at a minimum and the cost of frying operations can be considerably lowered.

Daily Cleaning
WARNING:
HOT OIL WILL BURN - DO NOT RUSH THIS JOB.
1. At the end of each day or at the end of each shift, if the frying schedule is heavy, the frying medium should be drained and filtered into a receptacle.
2. Always filter the fryer when the cool zone under the burners is hot and liquid. A cold fryer heated up won't drain, because the frying medium in this zone will remain hard if using solid fat / oils.
3. Screw the drain extension pipe onto the end of the drain valve and position a suitable container and filter under the drain extension pipe.
4. Do not empty the total contents into one large container, as this will be dangerous and may be difficult when lifted up, to pour the hot oil back into the tank.
5. Alternatively use a Filter-Max.
6. Slip a muslin or other suitable bag over the drain valve. Crumbs will be caught in the bag but frying medium will strain freely through into the receptacle.
7. Open the drain valve slowly to minimise splashing, and take care not to overfill the container.
8. If necessary, use a drain stick to stir up any solid medium into the top medium to melt it.
9. When the tank has been drained, use a ladle or small pan with a handle and dip into the hot frying medium from the receptacle and pour around the sides and bottom of the tank to wash out crumbs and particles adhering to the tank.
10. Continue to dip and pour until all crumbs are washed down and into the filter bag.
11. Open the drain valve fully and check for any particles or crumb residue lodged in the valve. Clean out with a stiff nylon brush. Do not use a wire brush or metal rods as these damage the seating in the valve and will eventually lead to valve leakage. If the obstruction in the valve cannot be removed with a brush, use a wooden probe to dislodge the obstruction.
12. Wipe all exterior panels with a cloth dampened with detergent and rinse off any residue with clean warm water.
13. Clean the Control Panel with a damp cloth lightly moistened with a solution of water and a commercial quality foodservice approved detergent.
14. Once the daily cleaning operation is completed, close the drain valve and pour the frying medium back into the tank and continue the days work.
15. Cleaning the tank takes less time than frying one load of potatoes and will pay dividends in food quality and saving of frying medium.

Cleaning and Maintenance
Weekly Cleaning
NOTE: If the fryer usage is very high, we recommend that the weekly cleaning procedure is carried
out on a more frequent basis.
1. Proceed as for 'Daily Cleaning' to drain and filter the tank. Do not refill the tank with frying medium until it has been cleaned as shown below.
2. Fill the fryer with cold water to the normal fill level and add a high quality commercial cleaner that has been specifically formulated for fryers.
All purpose cleaners are not recommended
.
NOTE: Never use a caustic or lye solution, as this will leave a fat destroying film on the tank.
3. Heat the water to approximately 80-90°C.
4. Clean the fryer baskets at the same time by simply immersing them in the cleaning solution. Allow the fryer to soak for 5-10 minutes or as directed on the cleaner instructions. Remove the baskets and turn OFF the main burners.
5. Scrub the baskets and fryer tank lightly, but vigorously with a stiff nylon bristle brush to remove any remaining deposits.
DO NOT use a wire brush, as this will scratch the sides
.
6. Empty the fryer and rinse thoroughly with water. Use a 1 part vinegar to 15 parts water solution to rinse the tank and neutralise any cleaner residue. Use a weaker solution of up to 1 part to 25 water if this proves unsuitable for the cleaner being used.
7. Rinse the tank thoroughly with water, drain and dry.
8. Refill the tank with new filtered frying medium.
Stainless Steel Surfaces
a. With the tank(s) drained, cleaned and dried as shown above, clean the exterior surfaces of the
fryer with hot water, a mild detergent solution and a soft cloth. Note that the gas control knobs are a push fit onto the gas control valve spindles and can be removed to allow
cleaning of the front control panel. b. Dry all components thoroughly with a dry cloth and polish with a soft dry cloth. c. To remove any discolouration, use an approved stainless steel cleaner or stainless steel wool.
Always rub in the direction of the grain.
Periodic Maintenance
WARNING:
DO NOT ATTEMPT TO MOVE THE FRYER WHILST THE FRYER IS FULL OF OIL.
BEFORE ATTEMPTING TO MOVE THE FRYER, ENSURE THAT ALL THE OIL HAS BEEN DRAINED FROM THE TANK. REFER TO THE INFORMATION ON THE PREVIOUS PAGE ON HOW TO DRAIN THE OIL FROM THE FRYER.
NOTE: All maintenance operations should only be carried out by a qualified service person.

Pilot Burners will not light / stay alight.
Check gas supply is turned on. Turn on gas supply. Check gas supply is low or empty. Replenish gas supply. Thermocouple connection loose. Tighten thermocouple connection.
Over temperature lead connection to interrupter on thermocouple is loose. Loose connections will cause resistance to millivolt circuit and result in pilot outage.
Replace any damaged connectors. Tighten over temperature lead to the
interrupter on the thermocouple.
If sufficient pilot flame cannot be obtained, remove pilot orifice from pilot burner and check for blockage of the pilot burner and / or correct size.
If pilot can be lit but flame too small to impinge on the thermocouple.
If pilot flame OK but goes out after control knob released (after holding in for approx. 30 secs).
Check the oil temperature. If above 205°C, the over temperature will be open circuit.
Check the oil temperature, if the oil is cold, disconnect the thermocouple from the gas control, while holding in the control knob in the pilot position and using a multimeter measure the millivolts being generated between the thermocouple end and earth (place other probe of multimeter on body of gas control).
If connections OK, check for gas at the pilot burner by manually lighting the pilot burner.
Check adjustment of pilot flow by adjusting screw below control knob on gas control. Check the supply.
Check for faulty thermocouple or over temperature thermostat. Call service provider.
Wait for oil to cool to approximately 190°C and re-light pilot burner. If overtemp is operating OK the pilot should now stay alight.
With the thermocouple hot, millivolt reading should be between 20­30mV. If voltage reading below 15 millivolts the thermocouple is defective. Replace the thermocouple.
