2. DESCRIPTION OF THE UNIT
2.1 Technical description
The panels are made of galvanized steel plating, stainless steel or aluminium. Some of the visible
internal and external parts have been provided with a powder coating. The glass used is tempered.
The controls for operating the appliance have been mounted on the operator side of the unit. The
product contact parts are made of stainless steel AISI 304 or AISI 430 and tempered glass.
Heating in the unit is achieved by means of heated shelves in combination with an hot-air curtain per
shelf. The air curtain isolates the hot air inside the unit from the ambient air.
An electronic thermostat controls the temperature. The MTT has a multi temperature controller which
allows each shelf to have its own operation temperature. The electronic thermostat has been set at
the correct value at the factory. The set temperature can be changed between 104ºF and 158ºF.
One LED-module per level provides for lighting of the products. The LED-lighting and the heating
are switched on and off together. There are two MTT user variants; a solid back version and a pass
through version which allows the user to (re)fill products via the back side.
2.2 Intended use
MTT models have been designed solely to keep packaged products warm and to display them.
Any other use will not beregarded as intended use. The manufacturer accepts no liability whatsoever
for loss or injury caused by failing to strictly adhere to the safety guidelines and instructions in this

3.2 Installation and positioning
WARNING
Electric chock hazard. Grounding instructions: only connect the appliance to an
alternating current provided by a grounded wall socket, with a mains voltage in
accordance with the information indicated on the data plate of the appliance.
It is the consumer's responsibility to make sure the electrical installation conforms
with current national and local codes and wiring regulations.
Do not use a multi plug or extension cord. Such can result in fire, electrical shock, or
other personal injury.
Failure to follow these instructions can result in death or serious injury.
WARNING
Position the unit on a flat and horizontal surface. A temporally inclined plane of
maximum 5° is allowed.
•Be sure that the personnel have sufficient room to work with the unit.
•Keep a distance of at least 1 inch between the back wall and the unit.
•While positioning, keep the unit out of children’s reach.
•Do not position a unit near a doorway, a ventilation device or a refrigerator in order to avoid
any negative effects on the unit’s operation by a cold airflow. The unit is designed for a
maximum draft of 0.65 ft./sec.
•Do not place into direct sunlight.
•The unit should not be used below 68ºF ambient temperatures.
•The unit has a mains plug, and must be connected to a wall socket with the proper mains
voltage. The wall socket must be mounted by a certified electrician.
3.2.1 Applying price rail

3.3 Repositioning the glass shelves
The top shelf can be positioned at two angled positions (0º and 3º). Refer to installation manual.
3.4 Air blockers
It is important that the air blockers remain on the shelf. Because without the air blockers the
performance of the MTT cannot be guaranteed! The installation of the air blockers is shown on the
next page.
The air blockers have the following numbers:

MTT

opening which needs to be facing upwards. If the power cord goes around the unit,
the opening of the back plinth must face downwards.

Display multi temperature controller
A controller for each shelf to switch it on/off and control it separately. The controllers are positioned
in the same way as the shelfs. So letter ´A´ shows the top shelf controller and letter ´B´ shows the
bottom shelf controller.
Using the multi-temperature controllers
The shelves can be controlled individually or even turned off completely. In this way optimal holding
conditions for different food groups can be achieved (for example: depending on holding time,
product quality, packaging and accessories used).
When set to the same temperature uniform temperatures can be attained throughout the cabinet and
energy can be saved. Although every combination of settings is possible (ranging from completely
off to a setpoint between 104ºF and 158ºF), certain settings may influence the time it takes for a
shelf to reach operating temperature.
For example, if only one shelf is turned on it may take over 60 minutes instead of approx. 30 minutes
when shelves are all set to the same temperature.
If different setpoints are required, it is advised to assign the highest setpoint to the
top shelf and the lowest setpoint to the bottom shelf for optimal performance and
energy savings.
If you need any assistance in determining the best setup for your hot food-to-go offering (such as
temperature setpoint, packaging and accessories), please contact Fri-Jado.
