1 RECOMMENDATIONS
♦These appliances are for professional use, only qualified personnel should use them.
♦These appliances must be installed with sufficient ventilation to prevent the formation of an excessive
concentration of substances harmful for health within the premises in which they are installed.
♦The equipment is not designed to work in an explosive atmosphere. Due to this, it must not be installed in
a zone pertaining to the ATEX provision.
♦The rate of new air required for gas oven combustion is 2 m3/h per kW of heat rate (gas appliance).
♦The cooking appliances and their heating hobs reach high temperatures. BE CAREFUL, you may burn
yourself when using them, or handling accessories (grills, trays...).
♦The gas appliances are fitted with exhaust flues for burnt gases: NEVER COVER THE EXHAUST
APERTURES.
♦Vicinity: the vapour emitted when frying is a greasy vapour. It may ignite and consequently ignite the oil
bath if a source of heat (for instance, the flame of open burners or an other source of heat) is placed too
close to the oil bath.
♦DO NOT PLACE FRYERS DIRECTLY NEAR SOURCES OF HEAT SUCH AS OPEN BURNERS,
SALAMANDERS, etc.
♦Heated oil used for frying reaches the temperature of 180°C. CAREFUL ! You may burn yourself.
♦Do not start the fryer if the oil level is not within the minimum and maximum levels.
♦Watch condition of the oil batch : replace oil the colour of which turns to brown, which foams excessively
or smokes.
♦According to the standard EN 60 335, utilisation of used oil is dangerous: it has a reduced ignition point
and it is subject to sudden rises (danger of fire and abnormal swelling).
♦Do not add water or immerse too voluminous products soaked with water or not undrained in the fryer (it
may result in serious spillage and overflow).
♦Observe the maximum loads indicated.
♦The fryer must be used only for frying operations. Do not immerse foodstuffs other than those foreseen.
♦Use only fats/oils specifically "for frying and seasoning". The other fats/oils, especially animal fats, contain
compounds that may turn into toxic agents at high temperature.
♦Electronic regulation includes a safety temperature limit at 210°C. Beyond this temperature, the fry er
switches off and the red safety indicator switches on. Switch off the supply line to the fryer and hire a
technician of the After Sales Service.
♦During the ignition phase of the burner, it is advised to avoid the presence of electronic appliances close
to the fryer.

2.2 BEFORE START UP
- Wash and dry the tank.
- Filling :Liquid oil: fill just above the minimum level.
Solid oil: * Electric fryers
- In case of use of solid oils (which congeal when cold, such as palm oils) in
these fryers, melt at medium temperature half of solid oil and pour it liquid into
the fryer. Then add the remaining solid oil bars.
* Gas fryers
- Place the solid oil bars over the entire tank bottom.

Turn the adjustment knob to the desired temperature (adjustment from 140 to 185°C).
Electronic regulation controls heating by initiating an automatic melting cycle of solid oils.
When set temperature is reached, the heating indicator switches off: then you may immerse the basket.
The safety indicator (red colour) switches on in case safety temperature is exceeded (210°C), in case of
burner malfunction and in case the reinjection lever isn't correctly pushed back in place (battery filtering
option). In that case, push the reinjection lever completely (battery filtering option), if the indicator does not
turn off it is necessary to relaunch the fryer (get the knob to the stop position and reset it to the desired
temperature).
WARNING !: For quality frying and a good production, always wait until oil has reached its set temperature
to immerse the products. (Heating indicator off).

2.4 MAINTENANCE OF OIL BATH
After each use, drain a little oil from the bath to eliminate residue and water trapped in the cold zone.
Filter oil after 3 frying operations, as a minimum. Use the container and filter supplied or the trolley
accessory for filtering oil.
Replace oil bath after about 10 frying operations or when oil turns brown, smokes or foams
abnormally and persistently on the surface.
WARNING !:
- Never drain oil with temperature higher than 50°C.
- The standard container supplied with the fryers do not permit full drainage of the tank.
- Handling a container containing the whole of the tank contents is too risky. Proceed in several
stages by using the filtering trolley (optional accessory).
- The choice and quality of cooking products have a great influence on the hourly production and the
maintenance of the oil bath: for instance, you must systematically filter oil after cooking breaded
products.
- Always use oil supplied for frying. Do not leave heat on when not in use.
- Protect the bath from the light and oxidation when you are not using the equipment. Close the lid.
Oil deteriorates even if it is not used.
- Avoid draining product above the oil. Never salt over hot oil!
- The addition of new oil into a batch of used oil will not extend its service life.
