1.0 General remarks
1.1 Application
The following instructions contain information, which is fundamentally important and must be
taken into account during assembly, operation and maintenance. They must therefore be read
very carefully before installation and operation by the responsible specialist staff and the
operator(s). They must always be available for consultation at the place of operation.
General information about products – installation – initial operation – operating test – cooking
process – safety instructions – out of operation – fault finding – cleaning – support – are
described on the following pages.
1.2 Purpose of induction cookers
The Garland induction unit cookers are especially suitable as cookers in the kitchen and for the
preparation of meals on the table. A cooker can be used for cooking, warming up, keeping
warm, flambéing, roasting, etc.The cookers are to be used only with pans made of material
which is suitable for induction. There are specific manufacturers who sell special types of pots
and pans for induction cooking.
Do not use induction cookers to heat up any other metallic objects other than pots and pans
provided for it.
NOTE: For Wok models, only use supplied wok pans or "Spring of Swizerland" wok pans. Other wok
pans may not have the same shape as the ceramic wok bowl, causing overheating and cracking of
the ceramic.

•Is the control knob in ON position?
•Do you use a suitable pan ? (bottom diameter at least 12cm (5"), pan made of suitable material)
•Is the pan placed in the center of the heating area?
To verify if the pan is suitable, use a permanent magnet and find out if it sticks to the bottom of
the pan. If not, your pan is not suitable for induction cooking. Choose a pan which is
recommended for induction cooking.
If in spite of all positive controls and tests, the cooker doesn't work, refer to the
Trouble Shooting Section.

6Operation
Modes of operation
Heating
The induction cooker is switched on with the control knob (OFF àON). The cooker is
immediately ready for operation. The illuminated indicator operation lights means that energy is
being transferred to the pan.
The power rating is set by turning the control knob. The inductive power depends on the
position of the potentiometer:
•ñposition 1: minimum power
•ñposition 10: maximum power for GIU 2.5
•ñposition 12: maximum power for all other models

the number that points to the indicator operation marks the actual position of the control
knob.
OFF-position:
0 points to the indicator operation
ON-position:
any position, where other than 0 points to the indicator operation

Special Features of Garland Induction
1) Excellent Simmer Control
We have designed these units with excellent simmer control. The 3.5KW and 5.0KW units all
feature an infinite control and we have marked the overlays from 1-12 as the power increases.
(0-11 for GIU2.5) We have designed the units such that the range from 1-9 (1-7 on GIU2.5)
controls the heat from about 5% to 50% of total power, giving a great range of simmer control.
The power jumps dramatically for strong boiling and quick heat after that.
6.1 Cooking process
Due to the following characteristics, the operator must be more attentive when using the
induction cooker than it would be required with other appliances.
The heat storage capacity of this system is very low. If the heating level is changed with the
control knob, the food is immediately exposed to a different temperature. Empty pots and pans
will heat up very quickly and are then ready for cooking. Once this has occurred, carefully adjust
the heating level to the desired cooking level by setting and adjusting the power with the control
knob.
Set and adjust the power with the control knob. The pan should always remain in the center of
the heating area, otherwise, the bottom of the pan is heated unequally and the food inside the
pan may burn.
When heating up oil or grease, constantly check the pan to prevent oil and grease from
overheating and burning.
Comfort
The cooker only transmits energy if a pan is placed on the heating area. If you take the pan
away from the heating area, power transfer stops immediately. If the pan is put back on the
heating area, the selected power will be transferred to the pan again.
After switching the cooker to the off position the cooking will stop.
7. Safety instructions
7.1 Description of danger signs
This symbol identifies the safety
information which may cause danger
(personal injury) for people at
non - observance of proper operation
CAUTION Indicates a hazard or unsafe practice
which could result in minor personal injury
or property damage
Information signs mounted directly on the cooker must be observed at all times and kept in a
fully legible condition.

Example:
CAUTION
Refer to instructions before
operating or servicing the unit.
The staff for assembly, installation, commissioning, operation and maintenance must have the
appropriate qualifications. The field of responsibility, competence and supervision of the staff
must be defined and controlled.
7.2 Risk in the event of non-observance of the safety information
Certain risks may be associated with non-observance of precautions, including:
•danger to persons through electrical causes
•danger to persons through overheated pans
•danger to persons through an overheated cooking platform
7.3 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.
7.4 Safety information for the operator/operating personnel
•The heating area is warmed up from the heat of the pan. To avoid injuries (burning) do not
touch the heating area.
•To avoid overheating of pans by means of evaporating the contents, don't heat up pans
unattended.
•Switch the control knob off if you take the pan away for a while. This will avoid having the
heating process continue automatically when a pan is placed back on the heating area.
•Do not insert any piece of paper, cardboard, cloth, etc. between the pan 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 (closed cans, aluminum foil, cutlery, jewelry, watches etc.) on the
induction cooker.
•Persons with a pacemaker should consult their doctor before using an induction cooker.
•Do not place credit cards, phone cards, cassette tapes, or other objects that are sensitive to
magnetism on the Ceran plate.
•The induction cooker has an internal air-cooling system. Do not obstruct the air inlet- and air
outlet-slots with objects (cloth). This would cause overheating and therefore the cooker
would switch off.
•Avoid liquid entering into the cooker. Do not let water or food overflow the pan. Do not clean
the cooker with a jet of water.
•If the heating area (Ceran plate) is cracked or broken, the induction cooker must be switched
off and disconnected from the electric connection. Don't touch any parts inside the cooker.

7.5 Unauthorized reconstruction and use of spare parts
Reconstruction of the cooker or changes to the cooker are not allowed. Contact the
manufacturer if you intend to make any changes on the cooker. To guarantee safety, use
genuine Garland replacement parts and accessories. The use of other components voids all
warranties.
7.6 Improper operating methods
The operating reliability of the cookers can only be guaranteed with proper use.
7.7 Pan detection
During pan detection, the indicator light flashes. No power is transferred and the indicator lamp
flashes if no pan or an unsuitable pan is detected. Pans having a diameter smaller than 12 cm
(5") are not detected.
7.8 Control of the heating area
The heating area is controlled with a temperature sensor. Overheated pans (hot oil, empty
pans) can be detected. Energy transfer will be stopped. The induction unit must be re-started
after it has cooled down.
8Out of operation
If the cooker is not in use, make sure that the control knob is in the "OFF" position. If you don’t
use the cooker for a longer period (several days), unplug the unit.
Make sure that no liquid can enter into the cooker, and do not clean the cooker with a jet of
water.
9Trouble Shooting
CAUTION Do not open the cooker, dangerous
electric voltage inside
The cookers may only be opened by authorized service personnel.
Stop any actions if the heating area (Ceran plate) is cracked or broken, the induction cooker
must be switched off and disconnected from the electric supply. Don't touch any parts inside the
cooker.

bottom of the pan. If not, your pan is not suitable for induction cooking. Choose a pan which
is recommended for induction cooking. Chose a pan material suitable for induction
appliances.
2) The cooling-system (fan) starts to operate when the ambient temperature in the control area
exceeds 55ºC / 130ºF. At heat temperatures higher than 70ºC / 160ºF, the controller
automatically reduces the power to keep the unit in normal operating conditions. The cooker
runs in a non continuous mode. This mode can be heard.

10 Cleaning
The cleaning of the Ceran plate and the ceramic bowl is identical to that of other similar
surfaces like glass. Do not use corrosive or abrasive cleaning agents, such as grill and oven
sprays, stain and rust removers, scouring powder or rough sponges.
Before being cleaned, the Ceran plate must be cooled down.
Other maintenance and servicing work other than cleaning as described here, must be done by
authorized service personnel.
The following is a list of common types of soil and recommendations how to treat them:
Type of soiling Treatment
Slight soiling, no burned residues Wipe with a moist cloth (scotch), without cleaning
agent
Sticky soiling Remove with a scraper (razor blade). Then wipe the
heating area with a moist cloth
Lime deposits, caused by water
which has boiled over These spots can be removed with vinegar or a special cleaning agent
Food containing sugar, plastic,
aluminum foil Immediately scrape off the sugar, plastic or aluminum foil residues thoroughly from the hot cooking area,
e.g. with a razor blade.
After removal of the residues, clean it with a cleaning
agent.
If the heating area soiled with residues of sugar,
plastic or aluminum foil cools down without prior
cleaning, the ceramic surface might become
deformed by pinhead-sized pits
Make sure that no liquid can enter in the induction unit.

11 Support
A good maintenance of the induction cooker requires its regular cleaning, care and servicing.
The operator has to ensure, that all components relevant to safety are in perfect working order
at all times.
The cooker should be examined at least once a year by an authorized technician.
CAUTION Do not open the cooker, dangerous
electric voltage inside
The cookers may only be opened by authorized service personnel.
