USER MAINTENANCE
1. Before working on or cleaning the equipment, isolate it from the power supply and allow it to
cool to a safe working temperature.
2. Clean units regularly with hot water and detergent, do not use abrasive or chlorine based
cleaners on stainless steel. Take care to avoid wetting electrical components.
Do not use a water jet.
3. Clean the ceramic glass regularly. Avoid abrasive sponges or scouring agents and harsh
chemical cleaners like oven sprays. Remove dirt and food with a scraper or Vileda CERAN
cleaning sponge.
Once the ceramic glass has cooled, use a few drops of suitable cleaner on a paper towel or the
rough side of the sponge. Wipe the ceramic glass with a damp cloth and dry it with a clean cloth
or the smooth side of the sponge
If plastic, aluminium foil, sugar or sugary food has dropped onto hot ceramic glass,
scrape it off immediately. If these substances melt they can damage the surface.
4. Check the air filter regularly and replace if it is contaminated.
INDUCTION COOKING AND PAN SELECTION
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 it. The coil generates an alternating magnetic
field. When a pan with a magnetic base is placed on the cooking zone, eddy currents are created in the
base of the pan leading to the production of heat. The pan heats very quickly.
The quality of the cookware is important to the efficiency of induction cooking. The base of the pan
needs to be flat and 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.
Operation of the pan detection system is dependent on the size of the pan and its material.
Power available from the induction coil to the pan will vary and is dependent on size and pan material.
Induction generators make buzzing, whistling and clicking noises especially on lower power settings.
This is normal for this type of equipment.
The pan should be located concentrically over the ceramic glass target ring. If the inner ring of the
ceramic glass is visible around the pan, then the pan is too small.
RECOMMENDED PAN BASE DIAMETER
Rear Zone Front Zone
Recommended minimum pan Ø180mm Ø120mm
Limit of pan detection Ø135mm Ø90mm
Nominal coil diameter Ø210mm Ø145mm

LOW TEMPERATURE HOLD
The pan base temperature is monitored through the ceramic glass hobtop, allowing dishes to be kept
warm. The “u” symbol is displayed.
The food type, pan construction material and flatness of the pan base will have a significant effect on
the temperature of the pan contents. To comply with food minimum safe holding temperatures, pan lids
should be fitted and a temperature probe used frequently.
POWER LEVEL SETTING 1 – 9:
There are 9 power level settings available via the rotary control knob

POWER BOOST FUNCTION
The IH21 is rated at 3kW total power input.
Normal operation; the large rear coil is rated at 2kw, the small front coil is rated at 1kw (total 3 kW).
If the large rear coil is power boosted, its power increases to 3kW, the front coil will be shut down.
If the small front coil is power boosted, its power increases to 1.8kW, the rear coil is limited to 1.2kW.
Power boost is activated by turning the control clockwise from the level 9 position.
Note: Only one coil can be boosted at a time.
The power boost will run for a maximum of 10 minutes, after that time the zone reverts to level 9. It may
be boosted again providing the system internal temperatures are satisfactory.
AUTOMATIC HEAT-UP CONTROL (AHC):
This is an advanced function.
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.
The table below gives the preset time for each level setting (in seconds) according to the power level.
Power level setting 1 2 3 4 5 6 7 8
Preset time (secs) 40 72 120 176 256 432 120 192
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 will
revert to the “A” symbol and the induction hob will run at maximum power for the time shown in the
table above, before reducing power to the ‘final’ setting.
CONTROL LOCK FUNCTION
This function prevents unwanted operation of the induction 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.
IS429:ECN3369
PAN DETECTION FUNCTION
Each zone has pan detection; this prevents the coil from turning on without a pan being present. The
coil also turns off as soon as the pan is removed. If the pan is of the wrong material to operate with
induction equipment, the ‘no pan present’ symbol will be displayed.
RESIDUAL HEAT DISPLAY
When a pan is removed from the hobtop and the temperature of the ceramic glass exceeds 60°C, the
“H” symbol is displayed indicating a hot surface. Refer also to the error codes section.
Whilst the residual heat display is showing, leave the IH21 Induction hob connected to the power
supply. This allows the internal cooling fans to continue to operate. When the “H” symbol is
extinguished, the mains power supply may be switched off.
ERROR CODES
There are numerous “E” symbol error codes, these identify issues within the induction system and are
primarily of use when reporting a fault to the Service department at Lincat Ltd. Some errors can be
cleared by turning the control to the “off” position, or completely turning off and unplugging the IH21,
before switching on again.
The “lightning” symbol reports errors due to the control knob circuit. If a control knob is wound anti-
clockwise and held in the “control lock” position in excess of 30 seconds, the system may assume a
“stuck control” and display this symbol.
A reduction in performance during cooking may be attributed to a blocked air filter, or a confined
location with insufficient cooling airflow, or a failed cooling fan. These circumstances will cause the
generator to overheat. Eventually the control electronics will shut down the generator causing the “H”
symbol to display.
Replacing the air filter and ensuring an adequate supply of cool air will restore performance.
REPLACEMENT OF AIR FILTER
Disconnect from the power supply after allowing the Induction hob to cool down. Turn the hob onto its
side or back, taking care not to scratch the ceramic glass cooking surface.
Push the slide latch sideways, this will allow the filter cover to be lifted away from the base panel.
Remove the old filter and replace with a clean filter.
Shut the filter cover onto the base panel ensuring that the slide latch has fully engaged into the
receptacle.
Turn the hob the right way up and reconnect to the power supply. The hob is now ready to use.
Important: Do not operate the IH21 Induction hob without a filter being fitted otherwise dirt and grease
could be drawn into the electronics and impair safe operation.
