1. INTRODUCTION
This manual has been carefully prepared and reviewed to provide reliable information
and assistance for proper installation, use, and maintenance that will ensure proper
operation and prolong the life of the oven. This manual is divided into two parts, the first
part dedicated to the installation of the equipment at the working point, and the second
part focused on the cleaning and maintenance of the oven.
Before any intervention or use of the equipment, it is necessary to read this
manual carefully and completely.
The manufacturer declines all implicit or explicit responsibility for any errors or
omissions it may contain.
- The furnace may not be used by personnel who have not received any kind of
training, and who do not have the necessary skills or experience for the proper
functioning of the equipment. Do not let children use or play with the equipment.
- The owner of the equipment is obliged to have this manual read by personnel
responsible for its use and maintenance, and to keep this manual in a safe place
for use by all users of the equipment and for future reference. If the equipment
is sold to others, they must be given this manual.
- This oven must only be used for the purpose for which it was designed, i.e.
cooking, heating, regenerating or dehydrating food. Any other use can be
dangerous and can result in personal injury and property damage.
- The equipment is shipped from the factory once it has been calibrated and has
passed rigorous quality and safety tests that ensure its correct operation.
The manufacturer will disclaim any responsibility for problems caused by
improper installation, modification, use or maintenance.

If the oven is on, but not cooking/washing, slight pressure will start
the cooking/washing cycle.
If the oven is on and cooking/washing, slight pressure will cancel the
cooking/washing cycle.
Table 1: Control panel description.
The central display is a very important part when interacting with the furnace, since it
indicates the value of each firing parameter.
Figure 3: Central screen.

The parameter display format is explained below:
Icon
Function
The moisture level is shown with an H in the first digit. The humidity value is
shown below.
The chamber temperature is shown with a T in the first digit. The temperature
value in degrees Celsius is shown below.
The cooking time is shown with the two central points. The two digits on the
left are the hours, and the two digits on the right are the minutes.
Cooking can also be continuous. In this case, CONT appears on the display.
For continuous firing, press the adjustment key - until CONT appears in the
display.
The fan speed is shown with an F in the first digit. If the convection fan is on
high speed, HI is displayed. Otherwise, if the convection fan is at a low speed,
LO appears.
If the self-cleaning button is pressed, the central display will show the
message CLN. However, if the temperature in the firing chamber is too high to
perform the self-cleaning process, the message COOL is displayed, indicating
that cooling of the chamber must be performed prior to self-cleaning.
To start both self-cleaning and cooling, press START/STOP.

This icon indicates that a cooking or cleaning process has been completed.
The message DOOR appears when the door is opened during a cooking or
cleaning process.
In the case of an error, the first two digits of the display show ER, followed by
the error number. Refer to the chapter on errors for more information.
It is possible to change the operating parameters of the furnace. In the
parameter edit menu, the central display shows a P, followed by the parameter
number. The two digits on the right show the value of the parameter. Refer to
the chapter on the configuration menu for more information.
Table 2: Description of messages on the central screen.
2.1.1 Switching on the equipment
The equipment is switched on or off by pressing the START/STOP button for two
seconds.
In order to protect the furnace from possible overheating, some protective
elements may work even when the furnace is switched off. When the oven is at
a safe temperature it will automatically turn off.
If the equipment does not turn on, check the status of the safety thermostat and the
service switch, located at the rear of the equipment.

2.1.2 Cooking modes
There are three cooking modes: convection, mixed and steam. To select a particular
mode, tap on the corresponding button.
Figure 5: Cooking mode selector.
The convection mode acts as a forced convection oven without adding or removing
moisture from the baking chamber.
The mixed convection mode allows to regulate, in an intelligent and controlled way by
the oven, the elimination or contribution of humidity in the cooking chamber. To do this,
press the humidity button and adjust with the +/- buttons to the desired value. This value
is shown in the central indicator.

The steam mode saturates the cooking chamber with moisture.

Table 3: Cooking modes in Mychef ovens
In order to prolong the life of your oven, it may automatically reduce the
maximum temperature of the baking chamber.
In all cooking modes it is possible to humidify the chamber at will. To do so, press the
HUMIDITY button until the oven sprays water into the baking chamber.
2.1.3 Cooking control
2.1.3.1 Temperature and time controlled cooking
In the temperature and time control mode we choose a cooking mode, a temperature
and a time by adjusting with the +/- buttons after having pressed the TEMPERATURE and
TIME buttons respectively.
