OPERATING INSTRUCTIONS
Only qualified or trained personnel should use this appliance.
Do not place metal objects, aluminium foil and plastic vessels on the ceramic
surface, and do not use the surface for storage.
Rings, watches and similar objects could get hot when in close proximity to the hob
surface.
Users with heart pacemakers should consult with the manufacturer of the
pacemaker or their doctor.
Information
With induction cooking, heat is produced directly in the base of the pan. The
system comprises a ceramic glass hob surface with an induction coil beneath,
which generates an alternating magnetic field. When a pan with a magnetic base is
placed on the cooking zone, eddy currents are created in the pan base leading to
the production of heat. The pan heats quickly. The quality of the cookware is
important to the efficiency of induction cooking. The pan base must be flat with
good heat distribution. Generally, suitable pans are made from cast iron, enamelled
steel and stainless steel with a magnetic base. Unsuitable pans are glass,
earthenware, aluminium, copper and non-magnetic stainless steel. Use pans of the
size and type recommended.
Operation of the pan detection system is dependent on the size of the pan and its
material.

The pan should be located concentrically over the glass target ring. If the inner ring
of the ceramic glass is visible around the pan, the pan is too small.

It is normal for induction generators to make buzzing, whistling and clicking noises,
especially on lower power settings.
If the ceramic glass surface is cracked, immediately disconnect the appliance
from the supply.
Use
Connect to the mains supply and switch on via the On/Off switch located on the
base of the appliance (see Fig 4). The green neon will illuminate and the cooling
fan will be heard.

The following symbols are observed through the ceramic glass:
Fig 3
Low temperature hold
The pan base temperature is monitored through the hobtop, allowing dishes to be kept
warm. The ‘u’ symbol is displayed. The food type, flatness of pan base and pan
material will have a significant effect on the temperature of the pan contents, therefore
to comply with food minimum safe holding temperatures, lids should be fitted and a
temperature probe used frequently.

Power boost function
Power boost is activated by turning the control clockwise from level 9. Only one coil
can be boosted at a time.
The IH21 is rated at 3kW total input, therefore:
If the rear coil (2kW) is power boosted, its power increases to 3kW and the front coil
will be shut down.
If the front coil (1kW) is power boosted, its power increases to 1.8kW and the rear coil
is limited to 1.2kW.
The power boost will run for a maximum of 10 minutes before reverting to level 9. It
may be boosted again, providing the system internal temperatures are satisfactory.
Automatic heat-up control (AHC)
When activated, the AHC will give maximum power (level 9) to a coil for a preset time
before reducing to a lower power level set by the control. To activate, the control is
turned anticlockwise from the ‘Off’ position briefly whilst the ‘A’ symbol illuminates: the
control is then turned clockwise to set the ‘final’ required power (1-8). The display
reverts to the ‘A’ symbol and the hob will run at maximum power for the time shown in
the table, before reducing power to the ‘final’ setting.

Control lock function
This function prevents unwanted operation of the hob. When the control lock is active,
the ‘L’ symbol is displayed. It is activated and de-activated by turning either control
knob anticlockwise to the control lock position and held for approximately 6 seconds.
Pan detection function
This prevents the coils being turned on without a pan being present, and also turns off
the coil as soon as a pan is removed. If the pan is of the wrong material for induction
equipment, the ‘no pan present’ symbol is displayed. After use, switch off the hob via
the control and do not rely on the pan detector.

IS 519 ECN 3681 Page 9 of 12
Residual heat display
When the temperature of the hobtop exceeds 60oC after removal of a pan, the ‘H’
symbol displays, indicating a hot surface. (Refer also to the error codes section).
Whilst the residual heat display is showing, leaving the appliance connected to the
power supply allows the cooling fans to continue to operate. When the ‘H’ symbol is
extinguished, switch off the power supply.
Error codes
There are numerous ‘E’ symbol error codes identifying issues within the system which
are primarily of use when reporting a fault to the Service Department at Lincat. Some
errors can be cleared by turning the control off, or completely turning off and
unplugging the appliance before reconnecting.
The ‘lightening’ symbol reports errors due to the control knob circuit, i.e. if a control
knob is turned anticlockwise and held in excess of 30 seconds in the ‘control lock’
position, the system may assume a ‘stuck control’ and display this symbol.
A situation such as a blocked air filter, failed cooling fan or insufficient air flow to a
confined installation, may cause the generator to overheat, resulting in the ‘H’ symbol
being displayed. Replacing the air filter, cooling fan or ensuring an adequate air flow
will rectify the issue.
CLEANING
Do not use a water jet or steam cleaner, and do not immerse this appliance.
Clean all panels with warm water and mild detergent, do not use abrasive
materials. Dry with a soft cloth.
Clean the ceramic glass with a scraper or Vileda CERAN cleaning sponge –use a
few drops of a suitable cleaner on a paper towel or the rough side of the sponge.
Wipe with a damp cloth and dry with a clean cloth.
Check the air filter and replace if contaminated (see Component Replacement).
Plastic, aluminium foil or sugary food must be scraped of the ceramic glass
immediately. If these substances melt they can damage the surface.

SERVICING, MAINTENANCE AND
COMPONENT REPLACEMENT
Replacement of air filter
Cool the appliance and disconnect from supply. Turn the hob on its back or side
without scratching the cooking surface.
Push the slide latch (Fig 4) and lift the filter cover away from the base. Replace the
used filter with a new one. Reverse the procedure to re-fit the cover. Do not
operate the appliance without a filter, as dirt and grease could be drawn into the
electronics, impairing safe operation.
