•Induction equipment that is not installed correctly will have warranty voided. See Warranty, p.2.
4.1 Location
•The induction unit must be installed securely in closed counters. IMPORTANT: Allow easy access to unit
and cable connections for maintenance and service.
•The heat retaining plate has to be mounted on a leveled and even counter surface.
•The generator can be placed in a separate cabinet. All the connectors are located at the front.
CLEARANCE minimum 2.95”(75mm) for the connectors. Ensure the generator and connectors can be
accessed easily for electrical installation and service.
•Do not place the induction unit on or near a hot surface or any heat producing equipment such as an
oven or a deep fryer.
•Protect the induction unit from steam if the unit is placed next to high steam emitting equipment such as
pasta cookers, steamers, and water bath.
•Allow easy access to the control knob(s).
•Keep the induction unit away from combustible materials, vapors or liquids.
4.2 Ventilation
Proper cool air intake and ventilation is essential to the reliability and functioning of the induction unit. Please
ensure all requirements listed below are met:
•The air inlet and exhaust openings of the Generator must not be blocked. Clearance: minimum 1.57”
(40mm).
•The maximum air flow is 56.50cfm (96m3per hour) and therefore a minimal opening of 9.30 sq.in. (6000
mm2) is required.
•An optimal air intake must not be restricted by the installation.
•Ensure the induction unit always gets cool air intake. If necessary, draw in fresh air supply through an air
duct (not provided).

Installation RTCSmp Built-In Temperature Controlled Hold-Line
Part # 4532287 Rev 2 (1/20/14) 9
•When installing the built-in unit, ensure the intake air and exhaust air are conducted separately. The in-
take air and exhaust air must not mix. To avoid build-up of hot exhaust air inside the cabinet, draw the
exhaust air out of the cabinet. Build up of hot exhaust air will cause the induction unit to reduce power
or to switch-off. The air intake temperature must not exceed 104°F (40°C).
•We recommend drawing fresh intake air through an air intake vent with a removable air intake filter.
•It is highly recommended that an exhaust fan be installed into the cabinet at an appropriate location.
This will force hot air out the cabinet and away from the induction unit. Consult an electrical or
installation expert for the most appropriate location to install a cabinet exhaust fan.

followings:
•For stone countertop, keep a minimum gap of 4”
[101.6mm] between cut-outs and provide reinforcement
beam in between units.
•For other countertop materials, the glass-tops can be put
side by side, and the joints between glass-tops must be
water-tight, silicone sealed.
The Heat Retaining Plates can be installed in a variety of arrangements. Some examples are:
•(A) and (B): The plates are placed in a row, with or without gaps in between plates.
•(C) and (D): The plates are arranged in a rectangle, with or without gaps in between.

5Function Test
IMPORTANT
CAUTION When the unit is in use, the cookware will warm up the glass-top. To
avoid burn injuries, do not touch the glass-top.
•Remove all objects from the glass-top and verify that the glass-top is not cracked or broken.
CAUTION Do not continue if the glass-top is cracked or broken. Immediately
switch off the unit and if possible and safe, disconnect it from the
power outlet. Contact a Factory Authorized Service agency.
•Before carrying out the function test, the user must understand how to operate the unit.
•Always use a pan or a chafing dish suitable for induction cooking, having a bottom diameter of at least
5”(12cm).
•See 6.1 Proper Induction Serving Pans and 6.2 Proper Placement of Serving Pans.
•NEVER LEAVE AN EMPTY PAN ON AN INDUCTION HOB.
To perform a function test:
1. Put some water in the induction pan and place it in the center of the hob.
2. Turn the control knob to select a temperature between 122-212oF (50-100oC).
The digital Display underneath the Ceran glass shows the selected temperature with point (eg.
). Within 2 seconds, the display shows the actual temperature and the point blinks
. This means energy is being transferred to the pan and the water is heated.
3. Take the pan away from the hob and power transmission stops. The display shows the current
temperature without point, for example
4. Place the pan back on the hob and the heating process starts again. The point blinks.
5. Turn the control knob to the OFF-position and the power transmission stops. If the temperature is over
122oF (50oC), the display shows “hot”. Otherwise, the display is off.
When the knob is in an ON-Position and the display remains off, check:
•Is the induction unit connected to the power supply?
•Is the control knob in an ON-Position?
If the point blinks but the pan is not heated up, or the display shows the temperature without a blinking point:
•Are you using a suitable pan or dish? See section 6.1 Proper Induction Serving Pans.
•Is the pan placed in the center of the heating area? See section 6.2 Proper Placement of Serving Pans .

6Operating Instructions
IMPORTANT
•Induction units are more powerful, heat up pans quicker, and cook food faster than conventional cooking
equipment. Your induction unit will require different use and care than other conventional equipment. Do
not operate the induction equipment without reading this manual and follow all safety requirements. Refer
to chapter 1 Safety Requirements.
•This appliance is for professional use and shall be used only by qualified personnel.
CAUTION
Do not put any empty cookware on the hob when the induction unit is ON. The
induction unit heats up empty pans very quickly. Overheated empty pan can
cause personal injury and damages to cookware and the induction unit. See
Warranty, p.2.
To avoid overheating, always put food products or oil into the pan before
turning the induction unit on.
•Induction unit offers short cooking time. When you turn the power level up, the temperature of the pan and
its contents is changed quickly. Therefore especially when you heat up oil or grease, check the cooking
process frequently to prevent the oil or grease from overheating and burning.
•BROIL-DRY PROTECTION
The RTCSmp electronic temperature control monitors overheating at the pan base. When an overheated pan
(overheated oil, empty pan) is detected, energy transfer from the generator to the pan will be stopped
immediately. You must turn the unit off, let it cool down before re-starting the unit.
6.1 Proper Induction Serving Pan
IMPORTANT Using unsuitable cookware on the induction unit can cause the unit to fail prematurely, void
your warranty, or incur high service costs. Refer to Warranty, p.2.
•
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 glass-top cannot detect temperature correctly.
These pans will overheat the sensors below and eventually will damage them. Illustration below shows
examples of good and bad pans in cross-sections.
IMPORTANT: CONDITION OF CHAFING DISH OR PAN
•Material
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 is marked with an induction compatible symbol.

•Size
The RTCSmp HOIN800/1600/2400/3200 models are designed to work with induction suitable serving pans in
standard or GN (Gastronorm) sizes such as 1/1, 2/4, 1/2, 2/3, and 1/3. For optimal results, Garland has carefully
selected a range of special GN (Gastronorm) serving pans for purchase. Please contact your dealer for details.
6.2 Proper Placement of Serving Pan
Each Heat Retaining Plate of the RTCSmp HOIN800/1600/2400/3200 models is considered to be one heat-zone.
Each heat-zone is equipped with the latest RTCSmp sensor technology which enables temperature controls in
realtime. To obtain optimal results from the sensors, you must place the pan within the perimeter of the glass-top.
CAUTION A single pan must not cover more than one glass-tops. The bottom of the
pan must fit the glass. Otherwise, electronic components of the induction
unit can be damaged.
DO
Place pans within the perimeter of the
glass-tops.
DO NOT
A. Place a pan over two hobs.
B. Place part of a pan outside the hob.
C. Place metallic objects on the hob
when the induction unit is in
operation.

6.3 Temperature Control and Display
6.3.1 Configurations and Temperature Control
One RTCSmp HOIN induction generator can control up to four heat retaining plates. Hence, four configurations
are available, ranging from one to four heat retaining plates. For each configuration, one temperature control
switch controls up to two heat retaining plates. When two heat retaining plates are connected to one switch, both
plates would be set to the same set temperature.
Model Configuration
(Heat Retaining Plate(s), Control Switch(s), and
Induction Generator are shown)
HOIN800
One switch controls one heat retaining plate.
HOIN1600
Two switches; each controls only one heat
retaining plate.
HOIN2400
Two switches; one switch controls one heat
retaining plate and the other switch controls two
plates.
HOIN3600 Two switches; each controls two heat retaining
plates.
6.3.2 Set and Current Temperatures
Set the desired temperature by turning the control knob and the unit is immediately ready for operation. You
can adjust the temperature in an increment of 5oF (1oC), from 122-212oF (50-100oC). The digital display
underneath the Ceran glass shows the set temperature initially and then followed by the current/actual
temperature.
ON-Position
Any position where
“0”/Line is not
pointing straight up.
OFF-Position
“0” / Line is pointing
straight up.

Operating Instructions RTCSmp Built-In Temperature Controlled Hold-Line
20 Part # 4532287 Rev 2 (1/20/14)
6.3.3 Digital Display
Temperature followed by a dot:
When you turn the control knob, the digital display shows the selected temperature with a dot.
Within two (2) seconds, the display shows the actual temperature.
Temperature followed by a blinking dot:
The blinking dot indicates the induction zone is active and the current temperature is displayed.
This means the system has detected a pan in the heating zone and energy is being transferred
to the pan.
Temperature shown without a dot:
The display shows the actual temperature and the induction coil is dormant; no energy is being
transferred from the system to the induction pan at the moment or the system cannot detect an
induction pan.
NOTE Unit with more than one heat retaining plate (RTCSmp HOIN1600/2400/3200):
To maximize efficiency with minimal resources, power cycles through the heat retaining plates at set
intervals. This means when one plate is active and the temperature is shown with a blinking dot, the other
plates lay dormant with temperatures shown without dots. This is normal. However, ensure you are using
proper induction pans on the plates.
To shutdown the unit, simply turn the control knob to the OFF-position. If the ambient temperature is over
122oF (50oC), the display shows “hot”. Otherwise, the display is off.
6.4 No Pan No Heat
When a temperature is chosen, the induction unit only transmits energy when a pan is placed in the heating zone.
If you remove the pan from the heating zone, power transfer to the pan stops immediately. If the pan is put back
in the heating zone, power is transferred to the pan again.
After switching the unit off, there is no heat retained inside the unit.
6.5 When Unit is Not In Use
Best Practice: If the induction unit is not in use, ensure the control knob is in the 0 (OFF) position.
•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.
