4 Installation
IMPORTANT
Kitchen designers and installation contractors are responsible for designing and installing correctly the
appropriate support structures and ventilation system for the cooking equipment.
When designing kitchen cabinets for the induction equipment, please take into account all installation
requirements, including factors such as: ease of electrical installation, size of the power conductor, and
length of the wires.
The installation, including electrical installation, must be carried out by registered installation contractors
only. The contractors are responsible for interpreting all instructions correctly and performing the
installation in compliance with national and local regulations. The warning signs and rating plates on the
cooking equipment must strictly be followed.
Read ALL SECTIONS carefully, comply with all requirements listed and ensure all inspection is done by
qualified personnel.
Refer to the technical data given in chapter 3 Dimensions and Technical Specifications.
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:

Page 9
Installation RTCSmp Built-In Temperature Controlled Hold-Line
Ensure the induction unit always gets cool air intake. If necessary, draw in fresh air supply through an air
duct (not provided).
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 104F (40C).
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.

6 Operating 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.
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
CAUTION
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.
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.
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 Chafing Dish or Pan
IMPORTANTUsing 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.
IMPORTANT: CONDITION OF CHAFING DISH OR PAN
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.
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.
20 Part # 4532286 Rev 3 (6/10/14)

Operating Instructions RTCSmp Built-In Temperature Controlled Hold-Line
Size
Minimum size: The bottom of the chafing dish or pan must have a diameter of at least 5” (12cm). Otherwise,
the sensors will not sense the pan properly.
Do not use oversized pans on the induction unit. The bottom of the pan must fit the glass. When a hot,
oversized pan covers the silicone joint underneath, the heat from the pan may dry out the silicone overtime
and cause this water tight seal to break. The induction unit may fail eventually due to penetration of liquid
through the broken silicone seal.
6.2 Proper Placement of Chafing Dish or Pan on Single Hob
Each Heat Retaining Plate of the RTCSmp HOIN450/900/1350/1800 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 in the center of the hob. The pan
should always remain in the center for optimal performance.
Pans and pots must not cover more than one cook zone at a

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)

temperature.
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 HOIN900/1350/1800):
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

122
F (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 stops immediately. If the pan is put back in the
heating zone, power is transferred to the pan again.
Note that pan with a bottom diameter smaller than 5”(12 cm) is not detected by the system.
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.
