ELECTRICAL COMPARTMENT

To protect the induction unit and wiring, we recommend
isolating the generator, the coil carrier sheets, and the wires
in separate electrical compartments inside the cabinet
(Figure B, below).

The illustration below shows a simplified representation of
an installation.

Notice

To ensure reliability of the induction unit, the custom
built counter / island suite / compartments must have
sufficient ventilation for the exhaust.

The in-take air and exhaust air must not mix. Depending
on the air path and the amount of natural air movement,
it is highly recommended to install a fan or fans on the
cabinet to pull hot exhaust air away from the electronic
equipment, or to provide a separate exhaust air plenum.

Failure to provide adequate ventilation will cause
the induction unit to overheat, to reduce power, or to
shutdown.

Section 2 Installation

Mounting Structure Design and Installation

A custom-built support structure or mounting frame is required to mount the glass-top to the counter surface and to install
the induction compact line module. This section provides the main design criteria.

NOTE: Please contact Garland if you would require assistance on designing a proper mounting frame.

TWO METHODS OF INSTALLATION

Method 1: Install the unit from under the counter.

• The mounting frame is to be stud-mounted to the
underside of the counter-top.

• The glass-top can be installed either:

• from the top onto the same mounting frame for
the compact-line generator, or

• onto a separate support structure.

• This method allows the removal of the unit for service
and maintenance below the counter-top.

Method 2: Install the unit from above the counter.

• This method is suitable for custom built suite with
removable counter-top.

• The mounting frame is attached to the cabinet. The
compact-line generator can then be installed onto the
mounting frame from above.

• With a separate mounting frame for the glass-top, the
glass-top is installed onto the counter top.

• The whole counter top can then be placed onto the
body of the cabinet.

• Example of a custom designed mounting frame for
quad model:

Part Number 4532879 1/15 17

Installation Section 2

GENERAL DESIGN CRITERIA

Notice

Components of the structure made from steel in the
vicinity of the coils must not be magnetic.

If two coil carriers are installed in the same frame, a
partitioning plate made from non-magnetic steel must
be installed between the coil carriers.

• For all critical information regarding glass-top
dimensions and installation, refer to section “Glass

Installation Guidelines and Instructions” on page 23

• The generators should be accessible and removable
for service and maintenance. Note that all electrical
connectors are located on the front panel of the
generator.

• Features on the induction unit designed for installation:

A. Support Rails: There are support rails on each long

side of the unit. To install the unit, support these
rails on a mounting structure.

B. Locating Tabs: There are locating tabs at front of

the support rails for positioning the unit. In your
design, include slots or holes to insert these tabs.
Refer to the technical drawings of the compact line
generators for the exact locations of these tabs.

• It is desirable to include height-adjustable feature to
level the unit during installation.

• Use 10- to 14-gauge non-magnetic metal (typical12­gauge) for the mounting frame.

• The mounting frame should not interfere with the air
intake duct (provided in the air intake kit) or block the
air vents on the unit.

• Depending on the thickness and material of the
counter-top, additional reinforcement structure may
be required. Consult your counter-top supplier for
information.

CRITICAL DIMENSION FOR COMPRESSION

The RTCSmp sensors (“E”, illustration below) monitor the
cook-zone temperature constantly to ensure an accurate
and safe operating temperature. For the sensors to function
properly, they have to be compressed against the glass-top
constantly and evenly. The springs “D” supporting the coils
and sensors will allow this compression to occur during
installation.

Notice

Critical Dimension

After installation, the distance from the guard rail to the
glass, 40+/-1mm, must be obtained to get the correct

Glass Installation Guidelines and Instructions

GLASS INSTALLATION GUIDELINES

• The glass-top should be installed first before installing
the compact-line induction module.

• To allow the temperature sensors to work properly,
the induction module is to be compressed against the
underside of the glass-top after installation. See section

“Critical Dimension for Compression” on page 19

• The glass-top should be installed flush with the counter­top and bonded using silicone sealant (included in the
Air Intake Kit).

• The glass-top must not be adhered to the support
surface directly. Silicone gasket is provided for glass
installation. See procedure in “Glass Installation

Instructions” on page 24

• NOTE: Final installed thickness:

Thickness of glass + silicone gasket + silicone seal =
6mm + 3mm + approx. 0.5mm = total approx. 9.5mm.

• The glass perimeter should be sealed with silicone to
prevent penetration of any liquid into the interior. For
a typical installation, we recommend to leave a gap of

4.0mm / 0.16” between the glass and the counter-top to
be filled with silicone.

• To match the edged pattern on the glass and the
centers of the induction coils, the glass-top should only
be oriented in one direction as shown:

Warning

n

When residual current circuit breakers are used, it
has to be taken into account, that by switching on an
induction generator to a three phase power supply
system, leakage current can be caused for a short period
due to the asymmetry. This leakage current can activate
the residual current circuit breakers. While choosing
residual current circuit breakers, please note that the
generator generates direct as well as alternating current
in high frequency areas of approximately 20 kHz.
Our recommendation is to choose a residual current
circuit breaker suitable for these requirements. If the
residual current circuit breakers are used as protection
for personnel, the breakers must be in compliance to
the specific national and local regulations for personal
safety devices.

Proper Induction Cookware

CONDITION OF COOKWARE

Pans with layer separation (outward and inward bubbles),
arching or partially detached bottoms must be replaced.
When these pans are used, the sensors under the glass­top cannot detect temperature correctly. These pans
will overheat the sensors and eventually will damage
the sensors and the generator. Illustration below shows
examples of good and bad pans in cross-sections.

MATERIAL OF COOKWARE

Use cookware made of conductive and
magnetic materials. If the pan bottom attracts a
magnet, the pan is suitable for induction
cooking. Look for cookware that is labeled
“suitable for induction” or with an induction
compatible symbol.

Note the signals given by the green indicator lamp:

• The green indicator lamp flashes when the unit is ON
but without any pan placed on the hob; the unit is in
pan detection mode.

• As soon as a pan is put on the hob, the heating process
is engaged and the indicator lamp stops flashing and
remains bright. However, the indicator lamp will keep
flashing if the unit is unable to detect the pan or an
unsuitable pan is placed on the glass-top.

NOTE: Pan with a bottom diameter smaller than 5”(12 cm) is
not detected by the system.

When Unit Is Idle

Best Practice:

If the induction unit is not in use, ensure the control knob is
in the 0 (OFF) position.

Notice

Switch the unit OFF if you take the cookware away for
a while. This will prevent the heating process to start
automatically and unintentionally when a pan is placed
back on the heating area. If any person needs to use
the induction unit, he/she will have to turn the unit ON
intentionally.

• The induction unit continues to work in a power
reduction mode.

• The induction unit continues to work as usual.

• For any unit equipped with an indicator lamp or a digital
display, see section Troubleshooting Chart With Error

Code / Indicator Lamp Flash Code

• For any unit without an indicator lamp or a digital
display, see section Troubleshooting Chart Without Error

Code / Indicator Lamp Flash Code

• NOTE:

The cooling fan starts when the ambient temperature
in the control area exceeds 130ºF/55ºC.

At heat sink temperature higher than 160ºF/70ºC, the
controller automatically reduces power to keep the unit
in normal operating conditions. The cooker runs in a
non-continuous mode. This mode can be heard.

Common Causes for Induction Unit Failure

One or more of the following conditions may affect the
function or contribute to the failure of an induction unit:

• Using unsuitable cookware such as non-induction pans,
oversized pans, or damaged pans.

• High ambient temperature.

• Inadequate ventilation causing hot air to re-enter
through the air intake slots.

• Dirty air intake filter.

• Empty pan is left on the hob when the unit is ON.

Boil Test: Performance of Cookware

(Test for 3.5kW or 5.0kW Coil)

Perform a boil test to verify the performance of a pan for
induction cooking.

• Add one liter of cold water into the pan (optimal when
use pan with bottom diameter of 24cm) and bring it to
boil. Compare the total boil time to the guideline below:

• 3.5kW Coil, approx. 140 seconds

• 5.0kW Coil, approx. 85 seconds

If time to boil exceeds the above guideline, then the pan is
not suitable for achieving optimal efficiency. Please contact
your supplier to purchase suitable induction pans.

If the induction unit does not function as expected despite
using quality induction pans, refer to the troubleshooting
charts.
