3. GENERAL SECURITY AND ACCIDENT
PREVENTION STANDARDS
3.1 Personnel responsible for appliance use
The use of the appliance is reserved for trained personnel.
The personnel who operate the oven, including use, cleaning, installation,
handling, etc., should be familiar with safety standards and usage
instructions.
Do not allow any unauthorized personnel to use, handle, or clean the
appliance.
3.2 Electrical hazard
Work on the electrical power source and access to power lines is permitted solely
for qualified and authorized personnel. In all instances, the appliance must be
disconnected from the power grid before accessing any power lines.
If the appliance is placed on top of a cart or on moving tables, do not move while
appliance is connected to electrical current so as to avoid damages in the wiring,
drainage tubes, or water input tubes. If you want to move or change the position
of the appliance, disconnect the cables and the draining and water input tubes.
3.3 Thermal hazard
When the appliance is running, open the door slowly and carefully to avoid possible
burns from the steam or hot air that may escape the oven chamber.
Make sure the ventilation openings are not blocked. Do not install the
appliance near ammable products. Avoid placing the oven near heat
sources such as stoves, griddles, deep-fryers, etc. Check the safety
distances in the Positioning chapter.
ACCIDENT HAZARD! Be careful when using cooking vessels in the oven
when the top tray is set at 160cm or more from the bottom. You run the
risk of injuries caused by hot content from the GN trays.
Do not touch the metal or glass parts of the oven while it is running.
Temperatures may exceed 60°C. Touch only the door lever and the
control panel.

129
ENGLISH
3.4 Corrosive materials hazard
Take caution and appropriate security measures when handling cleaning products.
Always read the security label for the chemical products before using them and
following the usage instructions. These products in contact with any part of the
body can be abrasive and may result in skin and eye irritations and chemical burns.
When cleaning the combi oven, if aerosol or mist result from handling cleaning
product containers, use a mask with a P2 / P3 particle filter, safety splash goggles,
and chemical protective gloves.
Distform detergent is recommended for cleaning the oven.

4. RECEIPT, TRANSPORT, AND POSITIONING
Before installing, verify the dimensions of the area where the appliance will be
installed and verify the electrical and water connections to ensure they are within
the parameters indicated in the installation sheet attached in chapter 6.
4.1 Receipt
Once the oven has been received, check that the model corresponds to the model
ordered.
Check to ensure that no damage occurred during transport and that no pieces
or parts of the appliance are missing. If any abnormality or problem is detected,
contact the distributor immediately.
4.2 Transport
The appliance should be transported with the original packaging until reaching the
site closest to the installation area in order to minimize the possibility of damages.
It is recommended that the original packaging be kept intact until the appliance is
correctly installed and functioning.
To move the appliance and place it in the workspace, note the appliance dimensions:
- Note the following dimensions for the dierent models when moving
appliance through narrow areas (hallways, doors, narrow spaces):
Model Dimensions (Width x Depth x Height)
4GN 2/3 520 x 625 x 575 mm
4 GN 1/1 520 x 799 x 575 mm
6GN 2/3 520 x 625 x 694mm
6GN 1/1 520 x 799 x 694 mm
10GN 1/1 520 x 799 x 935 mm
Table 2: Exterior dimensions for the dierent models.
- Use appropriate sta to handle and move the appliance, keeping in mind
current work safety standards at the installation site.
- The oven must always be in a vertical position during movement. Lift the
oven perpendicular to the ground and transport it parallel to the ground.
- Be sure that during transport, it does not overturn or hit any object.

131
ENGLISH
4.3 Positioning
- The oven should be placed at a distance from the wall that allows space
for electrical and water connections. Each part of the oven has space
requirements so that ventilation and cooling can properly occur. The space
requirements are as follows:
o 50mm on the left and right sides
o 100mm on the back
o 500mm on the top
- The appliance should be placed on a MyChef support table or a wall support.
- If heat sources are close to the appliance (stoves, charcoal grill, grill, deep-
fryer, etc.), they should be kept at a distance greater than 1 meter.
- Once the oven is placed in the workspace, be sure it is level.

To install stacked MyChef ovens, follow the instructions provided
with the stacking kit.

5. INSTALLATION
5.1 Electrical connection
Check that the voltage at the point where the oven will be connected is the correct
voltage for the the appliance.
Before doing any electrical work, be sure that there is no electric current at the
appliance connection point.
The appliance should be connected to the electrical grid through a multi-pole
circuit breaker with a contact gap of 3mm or greater. Also install a type A dierential
relay and and an overloading protection device.
Always ensure that the electrical environment is properly grounded.
Connect the appliance to an equipotential bonding system by using the contact
gap established expressly for this purpose (see equipotential symbol in the
bottom left corner of the appliance). If two appliances are stacked, both should
be equipotential bonded.
Connection to an equipotential bonding system ensures additional
protection in the event of simultaneous earth leakage and dierential
failure.
Wiring and other safety devices used in the electrical installation should have the
appropriate length for the appliance involved.
At all times, adhere to the current standards for connecting appliances
to a low-voltage grid.
Before beginning electrical installation, check that the electrical requirements of
the oven and the electrical grid supply are the same.
After the appliance has been positioned, a proper connection requires a length of
wire long enough to reach the connection point plus an additional 20cm in order
to connect to the back of the appliance. Remove back panel from appliance. Insert
the wire through the stung box located in the bottom left section of the oven
(from a rear view of the appliance).
At the time of installation, all MyChef ovens, with the exception of MyChef 4GN
2/3, can be configured to operate in single-phase or three-phase systems, and at
230VAC or 400VAC. To create a proper connection, use the electrical terminal
connectors that are provided with the appliance and follow the instructions in the
following subsections.

133
ENGLISH
Figure 4. Electrical terminal connectors. Figure 5: Wire input.
Once the connection is made, ensure that there are no loose wires and that all
wires are firmly secured. Also check the wire stung box.
Never connect a phase to neutral or ground wires. Check that the
installation voltage corresponds to the appliance power requirements.
In the following subsections, three types of possible connections for MyChef ovens
are shown.

5.2 Water connection
5.2.1 Water input
Cold water (max. 30°C) ¾ inch, from 150 to 400 kPa fluid pressure.
Potable water with the following features:
- Hardness between 3ºf and 6ºf
- pH between 6.5 and 8.5
- Chloride level less than 30ppm
Use of water softener and filter required (BRITA Purity Steam 450 recommended)
In a new installation, let the water run until the connection is completely
cleaned. This process should be repeated each time work or repairs are
done on the water system that supplies the oven.
5.2.2Drain
In order for the steam system to function properly, the appliance should be
connected to a drainage system with a heat-resistant pipe. The drain pipe must
have a nominal diameter of 40 mm (DN40).
Note that the drain pipe must have a minimum constant slope of 5º in order to
properly function.
Figure 14: Siphon drain installation.

5.3 Condensation hood
The condensation hood is an optional feature. The hood can be
installed after the oven is installed.
See the installation guide provided with the condensation hood to install.
