DRAINAGE
 Always allow the oil to cool to a maximum 55 oC before draining.
 Remove the blanking nut from the front of the unit (Fig 3, 5). Fit the drain pipe,
which has a stowage clip under the lid, and place a suitable receptacle under the
pipe outlet. Lift the safety catch (Fig 3, 7) and operate the tap by moving the handle
(Fig 3, 6) to the right to drain. Remove the pipe and fit into its storage position in the
lid. Replace the blanking nut and close the tap before refilling the tank.
 Take care when draining the oil that the drain bucket is not filled so full that it is
difficult to handle.
 Excess oil remaining in the base of the tank can be mopped up using kitchen paper.
CLEANING
Note: Clean the appliance with hot water and a mild detergent – do not use abrasives. In extreme
conditions a branded cleanser such as “Carb „n‟ Off ” makes cleaning easier after an overnight
application.








Isolate the appliance from the gas supply.
Allow the oil to cool to a maximum 55 oC.
Drain as per above instructions.
Wash the tank and the top surface of the fryer body.
Clean the drain tube assembly, using a tube or flue brush suitable for 15mm tube,
with the drain valve in the open position. Clean by inserting the brush into both the
inlet and outlet of the drain.
Wash all parts thoroughly.
Ensure all parts are thoroughly rinsed and dried. To ensure there is no water left in
the drain tube, flush thoroughly with a small amount of clean cooking oil.
Re-assemble by reversing the above procedure.
OPERATOR PRECAUTIONS
Never leave the unit unsupervised whilst frying.
Always drain food of excess moisture before frying, never put water into the oil.
Overheating the oil may lead to hazardous circumstances.
Ensure oil is always maintained at the level indicated (H-High, L-Low) to avoid
risk of hazardous circumstances.
Never use flammable cleaning agents on the appliance.
Under no circumstances should replenishment of the oil when the appliance is
hot.
NOTES ON FRYING MEDIA
Good quality vegetable oil is recommended. Animal fat may be used - but must always be
melted first. Animal fat has a lower smoke and fire temperature than vegetable oil and
taste is transferred when cooking with it (e.g. onions fried in animal fat will taint other foods
i.e. fish which may follow). This does not occur when cooking with vegetable oil.
The life expectancy of oils and cooking fats will be lengthened if they are filtered regularly food particles not removed turn rancid and reduce oil/fat quality.
Vegetable oils and animal fat are incompatible - e.g. if sausages containing a lot of animal
fat are fried in vegetable oil, the oil will tend to "glue" and spoil.
IS355 ECN3592
10
The life of oil or fat will also be extended if the temperature is turned down when the fryer is
not in use - otherwise if left "full-on" the oil is being subjected to needless heat treatment
and thereby destroyed.
Used oil symptoms firstly indicate discolouration by darkening. The oil becomes thin its fat
content having become exhausted. The next symptom is an unhealthy yellow foam which
may appear on the surface, and the third and more serious one is that the oil will boil or
"surge" if not changed - thereby causing damage. Be safe, not sorry. Keep your oil in
good condition and ensure a healthier food product and happier customers.
Please note also, that "spent" oil will have a lower flash point than new oil and therefore
present a greater fire hazard. Also avoid overflow from over-wet loads or over-large
batches.
In time, oil/fat may build up as a dried-on residue on tanks, baskets etc., although this can
be minimised on baskets by regular washing in hot water and detergent. If subsequently, it
cannot be removed by normal cleaning, various branded cleansers are available such as
"Carb 'n' Off" which makes removal easy after overnight application. Carb „n‟ Off is
available from us Part No. FCB01.
If a fryer is to be out of use for a lengthy period, drain and clean the tank. Lightly oil tanks
below the batter plate with cooking oil.
FROZEN FOODS
When cooking frozen food, it is advisable to defrost the food before use. Cooking of frozen
food will affect the heating recovery time, lowering your cooking output.
FRYING TIPS
 Always use a good quality oil or fat, preferably oil which has a high breakdown
temperature e.g. pure vegetable oil.
 Do not exceed the recommended cooking temperature stated by the supplier.
 Always maintain the oil at the correct level.
 Do not use the Fryer until the oil is at its correct temperature.
 Only use very clean oil and filter it daily.
 Skim the surface of crumbs and pieces that float, to prevent burning and
contaminating the oil.
 Keep the pan clean.
 Do not overload the baskets.
 Use batter plate only if free frying of fish is required.
