• 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!

Installation and connection
CAUTION!
Installation and maintenance operations may only be performed by qualified professionals!

• Discard the complete packing material after unpacking the device.
• Carefully remove the protective foil from internal surfaces to avoid leaving any adhesive tape. If any adhesive tape does remain stuck, remove it using an appropriate agent.
• Place the unit on a flat, stable floor space which can support the weight and is not sensitive to heat.
• Not at any time should you place the device on an inflammable surface (such as: table cloth, carpet, etc.).
• You must not position the device near open fireplaces, electric ovens/arc furnaces, furnaces/electric heaters or other heat sources.
• Place the unit so that the ventilation ducts at the rear are not blocked in any way.
• Do not place the unit near walls or other objects made of flammable materials. Keep a minimum distance of 20 cm on all sides of the unit.
• Do not place any objects on the unit.

NOTE!
The device is not a built-in device and should not be installed as such!

Water hose
Ensure that a water spigot is located near the unit.

• Connect the unit using the water hose (3/4”) at the rear of the unit.
• Water hardness should not exceed 8.4° dH, to avoid deposit buildup.
• Water pressure should be 0.5 – 2 bars.

Use
Preparing the unit

• Prior to use, clean the interior and exterior of the unit with a soft, moist cloth and mild cleaning agent.
• Prior to first use, heat the unit without any foodstuffs inside. Set the temperature to 200 °C and timer to 30 minutes. A small amount of s moke or unpleasant odour may occur. This is normal during first use and will not reoccur. Open the glass door to let the smoke out.
• Clean the baking trays with a mild cleaning agent. Rinse in clean water and dry with a soft, dry cloth.

Setup

NOTE!
Pre-heat the oven prior to each use, to allow for even heat distribution.

• The baking process is the effect of even distribution of air in the baking chamber. The air is heated by a heater and circulated by 2 ventilation motors.
• Use the timer to set the desired time. The control light will come on when this regulator is adjusted. The ventilators are operating.
• Use the temperature regulator to set the temperature. The pre-heating indicator will come on. When the desired temperature has been reached, the pre-heating indicator will go off.

WARNING! Danger of burns!
When in use, elements of the unit get very hot. Open the convection oven using the door handle. Wear protective gloves when operating the unit.

• Baking trays with the items to be baked may now be placed inside the chamber.
• Up to 4 baking trays may be inserted into the oven guides. Ensure a minimum of 40 mm between the trays and products being baked, so that the proper circulation of air is possible.

NOTE!
In order to achieve even baking results with a full unit ( 4 baking trays simultaneously) utilise only perforated trays (with openings)!

• The unit will automatically turn off after the set time has expired.

Humidifier
To prevent drying out of baked goods, the oven has a humidification function. Humidification is activated by pressing the humidification button. The humidifier control light will come on. Water is in this way sprayed into the baking chamber. The ventilators will distribute the water onto the heaters, which created steam in the baking chamber. Water is sprayed into the unit as long as the button is held.

NOTE!
Use the humidifier when the oven is hot. Press the humidifier button for only a short time, as otherwise too much water may gather at the bottom of the unit. Generally a quick humidification at the beginning of the baking process is sufficient.
