IS 565 ECN 3766 Page 6 of 13
The IH series countertop induction hobs require cool air to operate satisfactorily;
they are not suitable to be sited over heated bases, electric ovens or other hot
cooking equipment.
The cooling air is drawn in through the air filter in the base of the unit; and hot air is
exhausted from beneath the unit, at the front.
It is important that hot exhaust air cannot be drawn back into the inlet filter as this
recirculation will degrade the performance of the induction system, leading to an
overheat shutdown.
OPERATING INSTRUCTIONS
Only qualified or trained personnel should use this appliance.
Do not place metal objects, aluminium foil and plastic vessels on the ceramic glass
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.
Control knob operation:
Connect to the mains supply and turn on using the switch located in the base panel.
The green neon will illuminate and the cooling fan will begin operating. (The IH42
has two supply cords, two switches and two neons).

Power boost function
Power boost is activated by turning the control clockwise from level 9.
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.
On the IH3, power boosting raises the coil from 2.4kW to 3kW.
On the IH21 and IH42, if a rear coil (2kW) is power boosted, it’s power increases to
3kW and the front coil will be shut down. If a front coil (1kW) is power boosted, it’s
power increases to 1.8kW and the rear coil is limited to 1.2kW.
The IH42 has independent left and right side generators; one coil on the left side and
one coil on the right side can be power boosted at the same time.
Automatic heat-up control (AHC) this function may not be available in all models.
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 for 2 seconds
whilst the ‘A’ symbol illuminates: within the next 10 seconds the control is turned
clockwise to set the final required power (1-8). The display then alternates between
the ‘A’ symbol and the set power level. The hob runs at maximum power for the time
shown in the table, before reducing power to the set power level.

Control lock function this function may not be available in all models.
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 front and rear
control knobs anticlockwise to the control lock position, and holding for approximately
6 seconds.
This has to be performed separately for the left side and right side of the IH42.
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.
Always use the control to switch off the hob after use.

IS 565 ECN 3766 Page 10 of 13
Residual heat display
When the temperature of the hobtop exceeds 60oC after removal of a pan, the ‘H’
symbol displays, indicating a hot surface, (See also the Error code section).
Leaving the appliance connected to the power supply whilst the residual heat display
is showing allows the cooling fans to continue to operate. When the ‘H’ symbol is
extinguished, the power supply can be switched off.
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, or by allowing the unit to cool down.
The ‘lightning’ 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 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.
Locating the appliance where the exhaust airflow is constrained and allowed to
recirculate back into the air inlet, will eventually cause overheating of the unit.
The ‘H’ symbol will also display if the operating time limit is exceeded, this time limit
varies with power level (see Power Level Settings).
Turning the control off and then back on, will resume operation.
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 off 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, the filter is located in the base of
the appliance.
Raise the latch and lift the filter away from the base. Replace the used filter with a
new one and reverse the procedure to re-fit. Do not operate the appliance without a
filter, as dirt and grease could be drawn into the electronics, impairing safe
operation.
