• In the event of thunder storms (lightning etc.) immediately switch off the power supply. This will prevent damage to the device caused by strokes of lightning.
• Do not move or tilt the device when in operation.

WARNING! Hazard via electrical current!

The device can cause injuries due to improper installation!

Before installation the local power grid specification should be compared with that of the device (see type label).

Connect the device only in case of compliance!

Take note of the security advice!

5.2 Installation and connection

CAUTION!

The installation and maintenance of the device should only be carried out by trained personnel!

• Discard the complete packing material after unpacking the device.
• Remove the protective foil from the device. Ensure that it has been completely removed.
• Place the device on top of an even and safe surface which supports the weight of the device and is not heat sensitive.
  Not at any time should you place the device on an inflammable surface.
• You must not position the device near open fireplaces, electric ovens/arc furnaces, furnaces/electric heaters or other heat sources.
• Keep a minimum safety distance of at least 20~cm to walls or other objects.

WARNING! Danger of fire!

Make sure that there are no flammable materials on and around the installation site. Keep a sufficient distance on all sides.

• Do not place inflammable acidic or alkaline materials or cloths close to the appliance since this may reduce the operational life of the device and may involve the danger of deflagration.

NOTE!

This device is not suitable for built-in use nor for being set up in multiple in-line series.

• Place the device in well-ventilated rooms.
• Arrange the device so that the power plug are easily accessible.
• The rear side of the device is fitted with an earthing pin. Please connect the earthing cable to a copper wire (minimum diameter 2mm^2 ) in accordance with the generally applicable safety regulations.

5.3 Operating

Prior to first use

• Keep the device turned on at the highest temperature for approx. 2 to 3 hours to remove the production residues. Then leave the device to cool down.
• Clean the pizza oven (see chapter 6.2 "Cleaning").

Putting the device into operation

• Connect the device to a grounded single outlet.
• Turn the device on with the ON/OFF toggle switch.
• The temperature is set individually for each baking chamber with the temperature control.
  Each baking chamber of the pizza ovens NT series (with the exception of 200.2027) has two heating elements. The one heating element is located below the pizza stone made of chamotte, the other heating element in the top part of the pizza oven. The heating elements are set via the temperature controls for top and bottom heat.

NOTE!

• The pizza oven 200.2027 has only one baking chamber, which is divided into two individual chambers by the chamotte pizza stone. This pizza oven has 3 heating elements and 3 temperature controls. The top temperature control serves to set the top heat, the bottom one to set the bottom heat. The heating element in the center of the pizza oven is located directly below the pizza stone. It therefore serves as top heat for the bottom part of the baking chamber and as bottom heat for the top part. The temperature control in the center serves to set the temperature in this section.
• Set the desired temperature. The control lamps for the top and bottom heat light up.
• The adjustable temperature range of the pizza oven is between 0^ - 400^ . The recommended temperature setting is between 300^ - 400^ .
• Once the set temperature has been reached, the control lamp goes off. When the temperature in the baking chamber sinks, the control lamp lights up again and the heating element heats up until it has reached the set temperature again.

NOTE!

Always preheat the pizza oven prior to baking pizzas!

• Once the desired temperature has been reached, open the door of the pizza oven using the handle.
• Place suitable pizzas into the baking chamber of the pizza oven and close the door.
• Do not leave the pizza oven unattended during operation.

• Observe the baking process through the window in the door.

• Once the baking process is finished, turn all temperature controls counter-clockwise up to the marking 0^ . Turn the device off with the toggle switch. Then open the door.

• Remove the baked pizzas from the oven.

WARNING! Risk of burns!

Some parts of the device get very hot during operation. Do not touch the device parts with bare hands or fingers. Wear protective gloves when removing the pizzas, which reach above the wrists and use kitchen utensils with long handles to prevent burns.

• Disconnect the device from the mains outlet if you are not going to use it any longer.
