Gas & electric combi ovens

Table of Contents

♦

These appliances are for professional use, only appropriately trained personnel should use them.

♦

These appliances are intended to be used for commercial applications, for example in kitchens of restaurants, canteens, hospitals and in

commercial enterprises such as bakeries, butcheries, etc., but not for continuous mass production of food.

♦

These appliances must be installed with sufficient ventilation to prevent the formation of an excessive concentration of substances harmful for

health within the premises in which they are installed.

♦

The rate of new air required for combustion is 2m3/h per kW of heating power.

♦

The equipment is not designed to work in an explosive atmosphere. Accordingly it must not be installed in an area covered by the ATEX directive.

♦

Never block the condensate exhaust flue, because the pressure could rise in the appliance and pose a risk of explosion.

♦

If an error message appears consult the list of error messages and follow the ADVICE given

♦

When cleaning high pressure jets or lances should never be used.

♦

NEVER start the oven WITHOUT HAVING POSITIONED AND LOCKED the ventilation duct.

♦

Do not remove the ventilation duct and the drain grid located in the oven. If this grid is missing do not start the oven.

♦

Always use a qualified technician to install the equipment and if necessary change the oven from one gas to another.

♦

IMPORTANT: Please be aware that when cooking dishes prepared with alcohol (coq au vin, pears in wine, etc....). Vapour saturated with alcohol

may when heated cause an explosion in the oven and due to the sealed door, create a momentary overpressure which may cause an irreversible

deformation of the panels. This risk is further increased when the user adds alcohol to the products near the end of the cooking cycle and closes

the door to complete cooking.

♦

The appliance must be isolated electrically during cleaning or maintenance and when replacing parts.

♦

The control panel is operated via a serigraphic touch screen using your fingers. We recommend the exclusive use of your fingers and no other

items such as knives, forks or spoons etc.

♦

For long term reliability and safety it is advisable to have the unit serviced by suitably qualified technicians

inspection and cleaning of venturis, cleaning nozzles, adjustment of air rings, cleaning vents, checking for possible leaks, checking control

elements, regulating and safety accessories...).

♦

The oven must be meticulously maintained on a DAILY basis (see the "Maintenance" chapter). In particular, the fans, heating elements

and walls must be kept clean, without accumulation of grease and mineral deposits (lime or other).

♦

Preheating (20 level ovens): Whatever the cooking mode, these ovens are designed to be preheated with the trolley in place. See « Practical

operating advice ».

♦

Using a trolley or preheating plate (optional) is compulsory for automatic cleaning of 20 level ovens.

♦

It is strictly forbidden to open the door of the oven during the cleaning cycle.

♦

Never place the core probe behind the ventilation duct (the probe could be damaged by the fan, an element or the gas heat exchange).

♦

THE APPLICATION OF ANY CLEANING PRODUCT ONTO A HOT SURFACE, OVER 60°C, IS STRICTLY FORBIDDEN. The surface will be

damaged beyond repair (darkened, virtually black).

♦

Combination ovens should be cleaned with specific products which can resist temperature of up to 70°C. An inappropriate cleaning or descaling

product may have a slightly corrosive effect.

♦

The detergent chemical risk should not exceed 3 in accordance with EN 1717 (Toxicological information FDS: LD50 > 200mg/kg).

♦

We strongly recommend the use of cleaning products supplied by the manufacturer to ensure good results and optimize the service life of its

components.

Except for the UK market: No detergent product is recommended or supplied. Any detergent used with this appliance must have been verified to

represent no greater risk than Fluid Category 3. If the detergent used represents a Fluid Category risk greater than Fluid Category 3 alternative

backflow protection to the double check valve supplied with the appliance will be required immediately upstream of the appliance. The backflow

protection used must be appropriate to the risk posed by the detergent.

♦

In order to ensure optimum cleaning results without the risk of chemical attack we recommend using our cleaning chemical BK101. Other

products can be used. Generally cleaning products that are compatible with our ovens should:

- have a composition based on potassium hydroxide with a concentration < 25%, WITHOUT sodium hydroxide

- be suitable for use at a temperature of 60°C.

- include anticorrosion agents

♦

For maximum efficiency of the descaling product without damaging the material and components of the oven, you should use an appropriate

descaler. The use of certain acids has an irreversible destructive effect that may cause significant damage. The descaling product must contain

corrosion inhibitors to prevent metal attack. It must also comply with legal requirements, in particular for material intended to come into contact

with foodstuffs.

Chemical products containing nitric acid are strictly prohibited. Recommended composition:

- Phosphoric acid <50%

- Corrosion inhibitor

♦

The automatic cleaning system is exclusively designed to achieve an introduction of cleaning and degreasing chemical. Never use a descaling

agent. This would damage the hydraulic system of the oven irreversibly.

♦

Under no circumstances should the oven be cleaned with grills or containers in situ.

♦

The core probe socket and USB port are fitted with silicone protective covers.

- Always put the protective cover in place (lowered to protect connections) whenever the socket is not in use.

- Never "clean" connections with a water hose or a sponge. (If the silicone cover is used and put back in place after use,

no maintenance is necessary).
