To turn the deep fryer off, press and hold knob "B" for a
few seconds; "HOT" will be indicated on the display panel
"A" for as long as the oil temperature remains above 60
°C; once it falls below this temperature, "OFF" will appear
on the display panel.
MELTING function
The Melting function activates the deep fryer cyclically,
allowing you to heat the oil without sudden increases in
temperature.
This function is mainly used during colder months when
the oil tends to solidify, or when using vegetable fat for
frying.
Operating intermittently, the deep fryer dissolves the fat
used for frying without the risk of it burning.
To activate the Melting function, press button "D"; LED
light "F" turns on and the display panel will automatically
indicate 100 °C. The deep fryer will start to operate in
cycles until the temperature reaches 100 °C, after which it
will automatically maintain the oil temperature at 100 °C.
The Melting function can be activated and deactivated at
any time by pressing button "D".
EN
If the Melting function is activated when the oil
temperature is over 100 °C, the deep fryer will wait
for the temperature to go down to 100 °C and then
automatically maintain the oil temperature at 100 °C.
Warnings
The appliance is equipped with the following safety
functions:
- if LED light "G" is on, it means that the heating element
is not fully pivoted into the horizontal operational
position;
- if LED light "H" is on, it means that the safety thermostat
has intervened (see the SAFETY DEVICES chapter)
In these cases, the deep fryer does not function until the
safety of the appliance is restored.
When you have finished using the deep fryer for the day,
turn off the main switch "C".
Use the automatic basket lifter, set the cooking time
(FA models, see Fig. 7)
The basket lifter can be used either with 1 basket or 2 half
baskets.
To use the basket lifter with 2 half baskets, set the fryer
compartment's "M" switch to the "2 baskets" position.
To use the basket lifter with 1 basket, set the "M" switch
to the 1 basket position. In this case, set the fry time by
rotating the right "A" knob. The left "A" knob is not enabled.
Set the frying time by rotating the "A" knob to the value
you want. As soon as the "A" knob is rotated, the basket
will lower. When the set time is reached, the cooking cycle
finishes and the basket lifts up.
Oil filtering and use of the pump (F and FA models, see
Fig. 7)
Make sure that the tray and the filter are positioned
under the oil drain. The oil should not be drained at room
temperature or soon after frying. Wait about 3 hours
after the last frying before draining oil; in any case, the
temperature must be lower than 90 °C. Be careful around
F AND FA MODELS
hot oil. Slowly rotate the "H" knob to open the drain tap.
Pay attention to oil splashes. Oil will flow out faster into
the tanks and the filter will clean it properly. If the oil is
particularly dirty, make sure that the oil does not overflow
from the filter. Close the "H" tap. To start pumping the oil
from the tray to the tank, rotate the "E" knob. As soon as
the "E" knob is rotated, the orange "F" light will illuminate
and the oil will start to flow out into the tank. To stop
pumping, rotate the "E" knob to 0; the tank will empty in
about 5 minutes. The colder the oil is, the longer it will take
to pump it.
The oil must have a temperature lower than 90 °C and a
viscosity lower than 350 cSt.
Performances
The PERFORMANCES table shows the maximum capacities
and the maximum production per hour of the various
models of fryers.
To have a few suggestions about the cooking times,
refer to the table COOKING TIME AND RECOMMENDED
TEMPERATURE.
MAINTENANCE
Maintenance must be carried out by qualified
personnel.
Disconnect the unit from the main power supply
before performing any operation.
Check the condition of the conductors, commands and
electrical heating elements. Use only original spare parts.
If the power supply cable is to be replaced, use H07RN-F
cables. (See the TECHNICAL DATA table).
After each technical intervention and any maintenance
work, the specialised installer must test the device before
switching it back on.
Warnings
It is necessary to periodically check the stuffing box system
of the deep fryers. The stuffing boxes on deep fryers
should be tight so as to avoid any oil leakage which in the
long run could cause problems.
CARE OF THE APPLIANCE
ATTENTION!
- Before cleaning, switch off the unit and let it cool
down.
- In the event of electrically supplied units, use the
isolator switch to disconnect the mains.
Carefully clean daily the appliance to guarantee its proper
operation and long life.
Steel surfaces must be cleaned with a dish washer
detergent diluted in very hot water by using a soft cloth;
for the toughest dirt, use ethylic alcohol, acetone or
another non-halogenated solvent; do not use abrasive
powder detergents or corrosive substances such as
hydrochloric acid, muriatic or sulphuric acid. The use
of acids can affect the unit's operation and safety. Do
not use brushes, steel cottons or abrasive disks made with
