4. RECEPTION, TRANSPORT AND POSITIONING

Before carrying out the installation, the dimensions of the site where the equipment is to be installed and the electrical and water connections must be checked, and it must be verified that they are within the parameters detailed in the installation sheet.

4.1 Reception

Once the furnace has been received, check that the model purchased corresponds to the order.

Check that the packaging is undamaged during transport and that there are no missing parts or pieces of equipment. If any anomalies or problems are detected, please contact your dealer immediately.

4.2 Transport

The equipment must be transported in its original packaging to the place closest to the point of installation to avoid damage as much as possible. It is recommended that the original packaging be stored until the equipment is properly installed and operating.

To move the equipment and place it in your workspace, consider the following observations:

- The dimensions of the different models to be taken into account when passing

through narrow spaces (passageways, doors, narrow spaces). See Table 1 and Table 2.

- The manipulation must be done with the necessary personnel to move the load

of the furniture taking into account the regulations in force regarding work safety at the place of installation.

- During the movement of the oven, it must always be in a vertical position. It

must be lifted perpendicular to the ground and transported parallel to it.

- Make sure that during transport it does not tip over and does not hit any

objects.

4.3 Positioning

5. INSTALATION

Connection to an equipotential bonding system ensures additional safety in the event of simultaneous ground fault and differential failure.

Observe the applicable regulations for connecting the equipment to the lowvoltage mains supply.

5.1 Electrical connection

Check that the voltage at the point where the furnace is to be connected matches the operating voltage of the equipment.

Before carrying out any electrical work, make sure that there is no electric current at the equipment connection point.

The equipment must be connected to the mains by means of an omnipolar cut-off switch and with a contact opening distance of more than 3 mm. Also install a class A differential device and overcurrent protection.

Always guarantee an efficient earthing system.

Connect the equipment to an equipotential bonding system using the specially designed contact for this purpose (see equipotential sign on the lower left side of the equipment). In the case of two stacked equipment, both must be connected to the equipotential bonding system.

Wiring and other safety devices used for electrical installation must have the appropriate cross-section for the equipment in question.

Before starting the electrical installation, verify that the electrical requirements of the furnace and mains supply are the same.

For correct connection after positioning, you will need a cable with a length that allows you to reach the connection point plus about 20cm, to make the connection on the back of the equipment. Remove the rear plate from the equipment. Insert the cable through the cable gland in the lower left-hand side of the furnace (see rear panel).

Some MyChef ovens can be connected to different voltages and configurations at the time of installation. To make the correct connection, use the terminal blocks supplied with the equipment according to the instructions in the following subchapters. These terminal strips are located between contacts 4 and 5 of the terminal block.

Figure 2: Terminal junction strips.

Figure 3: Entrada de cable y bornero.

Never connect a phase to neutral or ground. Check that the installation voltages correspond to those of the equipment.

Check, once the connection has been made, that no cable is loose and they are all firmly fastened. Also secure the cable gland.

The following subchapters show the three types of possible connections for MyChef ovens.
