1 Safety Requirements
WARNING This product contains chemicals known to the State of California to cause cancer.
Installation and servicing of this product could expose you to airborne particles of glass
wool / ceramic fibers. Inhalation of airborne particles of glass wool / ceramic fibers is
known to the State of California to cause cancer.
IMPORTANT Warning labels mounted directly on the induction unit must be observed at all times and
kept in a fully legible condition.
IMPORTANT To ensure your working environment is safe, you must follow all of the safety instructions
contained in this manual, the existing national regulations for accident prevention with
electrical systems, as well as any relevant company-specific safety instructions.
he induction unit should only be used if and only if the
installation of the electrical system is fitted by an approved
installation contractor in accordance with specific national and
local regulations.
1.1 Risk Involved By Disregarding Safety Information
Disregarding the safety instructions may cause harm to people, the surroundings, and the induction unit. Garland
is not responsible for any damages or personal injury caused by failure to observe the safety requirements. Risks
involved when disregarding safety precautions may include:
Death or injury caused by electric shock.
Injury due to burns from contacting overheated chafing dish or pan or glass-top.
Damage to the induction unit caused by using unsuitable chafing dish or pan.
1.2 Safety Instructions for Operator
Please follow the following rules to avoid personal injuries and property damages:
When the unit is in use, heat transfers from the cookware to the glass-top; the glass-top can become hot. To
avoid burn injuries, do not touch the heating area when the unit is in use.
If the glass-top is cracked or broken, switch off the induction unit immediately and if possible and safe,
disconnect it from the power supply. Do not touch any parts inside the induction unit.
Persons with a cardiac pacemaker should consult their doctor whether they are safe near an induction unit.
If the power cord is damaged, have it replaced immediately by an approved service technician.
The induction unit heats up cookware quickly. Do not leave an empty pan on the unit and do not leave the
unit unattended during operation.
Do not put any other items on the glass cook-top except non-empty induction chafing dish or pan.
o Do not leave any object such as paper, cardboard, or cloth between the cookware and the cooking
surface, as this might start a fire.
4 Part # 4532286 Rev 3 (6/10/14)
Safety Requirements RTCSmp Built-In Temperature Controlled Hold-Line
o Metallic objects are heated up very quickly when placed on the induction unit when the unit is in
use. Do not place any objects such as closed cans, aluminum foil, cutlery, jewelry, or watches on the
induction unit.
o Do not place credit cards, phone cards, tapes, or any objects sensitive to magnetism on the cooking
surface.
o Do not place plastic vessels and aluminum objects such as aluminum foil on the glass-top.
Ensure liquid cannot enter into the induction unit. Do not let water or food overflow the cooking area. Do not
use hoses to clean or power wash the induction unit or its vicinity.
The induction unit has an internal air-cooling system. Do not block the air intake and exhaust openings with
objects such as cleaning cloths or containers. Any obstruction to the air intake and exhaust could cause the
unit to overheat and to switch off.
Switch the unit OFF if you take the chafing dish or pan 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.
Use only induction suitable chafing dishes or pans with proper sizes and made of proper material. The
induction suitable serving dishes or pans should also be in good condition without any uneven, arched or
partially detached bottoms.
1.3 Improper Use of the Equipment
The reliability of the induction unit can only be guaranteed when it is used properly. The induction unit must
always be operated within the limits provided in the technical specifications. Please refer to section 9 Important
Rules of using induction equipment.
1.4 Unauthorized Modification and Use of Spare Parts
Please contact the manufacturer if you intend to make any changes on the induction unit. For safety reasons,
always use genuine parts and accessories approved by Garland. Any unauthorized modification as well as any
installation of unapproved components will void all warranty. See Warranty, p.2.
1.5 Pan Detection
Energy is transferred to cookware when the induction system detects a suitable pan on the heating area. The
digital display signals to communicate the Pan Detection process.
When the unit is ON without any pan on the hob, the display shows the current temperature without a
dot; the unit is in pan detection mode.
As soon as a pan is put on the hob, the heating process is engaged and the display shows the current
temperature followed by a blinking dot.
However, if the unit is not detecting any pan, the current temperature is shown without a dot.
NOTE: Pan with a bottom diameter smaller than 5” (12 cm) is not detected by the system.

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:
The air intake and exhaust openings of the Generator must not be blocked. CLEARANCE: minimum 1.57”
(40mm).
The maximum air flow is 56.50cfm (96m
2
mm
) is required.
An optimal air intake must not be restricted by the installation.

per hour) and therefore a minimal opening of 9.30 sq.in. (6000
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.
4.3 Electrical Compartment Protection
To protect the equipment, isolate the unit and the wires in a separate electrical compartment inside the cabinet.
