not use it when the glass surface is cracked or broken, immediately switch off and disconnect
the unit from the outlet.
CAUTION
The glass surface is warmed up from the heat
of the pan or bac. To avoid injuries (burning)
do not touch this area.
Use a induction pan or bac that is suitable for keeping the food warm and having a bottom
diameter of at least 12 cm.

The glass surface must always be clean. No water residues or fouling.

Put some water in the pan and place it in the center of the right or left heating area.

Turn the temperature rotary knob ON (in a position between 51°C and 100°C). The
adjusted temperature appear In a red type below the glass surface (the water will be
heated). In the use LED and temperature in the display shines constantly.

Take the pan or bac away from the heating area. The function LED light will flash.

Turn the temperature rotary knob in the OFF-position, the heating process will stop,
indicator light turns off. By rest warmth bigger as 50°C appears signal HOT on the display
under the glass surface.
The blinking LED on the display means that energy is being transferred to the pan or bac.
If the indicator operation remains off, check the following:

Is the induction unit connected to the outlet?

Is the temperature rotary knob in ON position?

Do you use a suitable pan or bac (bottom diameter at least 12 cm and the pan or bac made
of suitable material?

Is the pan placed in the center of the right or left heating area?
To verify if the pan or bac is suitable, use a permanent magnet and find out if it sticks to the
bottom of the pan or bac. If not, your pan or bac is not suitable for use with induction. Choose
a pan or bac which is recommended for induction and keeping food warm.
If in spite of all positive controls and tests the induction unit doesn’t work, refer to the Fault
Finding Section.

Operation
5.1
Heat-retention process
This induction unit „RTCSmp Hold-Line“ is immediately ready for use. The temperature
level is chosen by turning the rotary knob under the ground sheet and the adjusted temperature
set point is shown constantly. The inductive transmission of power depends on the position of
the temperature. The blinking LED on the display means that energy is being transferred to
the pan or bac.
Due to the following reasons, the operator has to be more attentive than with conventional
heat-retention systems.
The heat storage capacity of this technology is very low. After turning the temperature rotary
knob to a different level, the pan or bac ground is exposed to the new adjusted temperature
level. Empty pan or bac heat-up very quickly. Do not put empty pan or bac on the glass
surface.
The pan or bac must be placed of one of the two heating areas, otherwise the bottom of the
pan or bac is heated unequally.
Never place a container with a temperature of more than 100°C onto the glass. This may lead
to a damage of the glass.
5.2
Comfort
The induction unit transmits energy only when an pan or bac is placed on the heating area,
independently of the position of the temperature rotary knob. If you take the pan or bac away
from the heating area, the power transfer stops immediately. If the pan or bac is put back on
the heating area, the selected power or temperature will be transferred to the pan or bac again.
After switching the induction unit to the “Off”-position, the heat-retention process is stopped
immediately.

Safety conscious work
The safety information contained in these instructions for use, the existing national regulation
for the prevention of accidents as well as any internal working, operating and safety
regulation stipulated by the operator must be observed.
6.3
Safety information for the operator/operating personnel

The heating area is warmed up from the heat of the pan or bac. To avoid injuries (burning)
do not touch the heating area.

To avoid overheating of pans or bacs by means of evaporating the contents, don’t heat up
pans or bacs unattended.

Switch the temperature rotary knob off if you take the pan or bac away for a while. This
will avoid having the heating process continue automatically when a pan or bac is placed
back on the heating area. So, if any person starts to use the unit, he/she will have to start
the heating process by turning the temperature rotary knob in the ON-position.

Do not insert any piece of paper, cardboard, cloth, etc. between the pan or bac and the
heating area, as this might initiate a fire.

As metallic objects are heated up very quickly when placed on the operating heating area,
do not place any other objects on the induction unit (closed cans, aluminium foil, cutlery,
jewelry, watches etc.). Persons with a pacemaker should ask their doctor whether they are
safe near an induction unit or not.

Aluminium foil and plastic vessels are not to be placed on the hot surface.
