Therefore, read these instructions before starting to use the oven. Do not service or repair either the oven or the control panel. Incorrect servicing or repairs may result in injury or damage. Adjustments and repairs must be carried out by service engineers who are trained and authorised by SVEBA DAHLEN AB. Keep this manual in a suitably safe place. Be very careful when transporting the oven on castors as its centre of gravity is high and there is a great risk of it tipping over if it strikes any obstacles on the floor. The oven must be connected to an all-pole circuit breaker with a contact gap of at least 3mm. 3-pole protection is recommended for use for safety in the electrical supply unit so as to ensure automatic disconnection of all phase conductors if there is a fault in even one phase conductor. The supply cable must only be replaced by an authorised specialist. The glass doors must only be cleaned with a damp cloth and a small amount of detergent. Do not use large amounts of water. See the section entitled Maintenance. The air intakes at the front of the underside of the oven must not be covered. Attention The unit must be secured against slipping by a chain or cable in order to prevent damage to the electricity supply line. To avoid damages on the supply line, the restraint cable must be shorter than electrical connection line.

This procedure will cause quite a lot of smoke from the oven, but this is completely normal. Therefore, ensure that the ventilation system on the premises is running and capable of removing the smoke. All oven sections may be burned out at the same time. · Close all the oven doors, open all the dampers and set the temperature to approx. 248 °F. · Start the oven using the on/off buttons on the panels. · When the oven has reached a temperature of 248 °F, leave it to stand for approx. 30 minutes. Then wipe down the inside of the glass doors using a dry cloth or paper towel. Take care not to burn yourself. · Increase the temperature to approx. 392 °F. Leave the oven to stand for approx. 15 minutes when this tempera- ture has been reached. · Increase the temperature to 464-482 °F and leave the oven to stand at this temperature for approx. 2 hours. The oven will then be ready for use. · When the oven has been switched off and left to cool, wipe the inside of the glass doors with a damp cloth. The coating on the glass which appeared during burning will burn onto the glass otherwise and will be very difficult to remove. The above procedure also has to be carried out when switching to new hearthstones in an old oven, and failure to perform this procedure will invalidate the warranty. If the hearthstone is replaced at a later date, it is very important to follow the above instructions on heating . The hearthstone will crack and be destroyed if it is heated up too quickly . Any smoke detectors may be triggered during the first burn of the oven in a small room with poor ventilation . Therefore, try to allow the smoke to escape by opening doors and windows, for example . The user is responsible for the machine being cleaned thoroughly before it is put into use. It is best to use a mild cleaning liquid on all surfaces that come into contact with food to guarantee that they are not contaminated. It is the user's responsibility to ensure that the machine is not put into use before it has been cleaned thoroughly. 6 Operation Maintenance Installation P600HT-N 860251-02 Introduction You can program the start and stop times for the entire week using the smart panel. This means that the oven will always be at the correct operating temperature when you start baking. If there is a difference between the required temperature and the actual temperature, this is adjusted quickly by the automatic turbo function. The oven's insulating properties are important for the work environment and result in a cooler workplace. Ergonomics are improved when the oven door does not have to be opened over and over in order to move the pizzas around before they are ready. The oven rests on a solid structure with sturdy legs, while also being easy to move using the lockable wheels. This makes cleaning, servicing and other work easier. The P-Series is very well insulated and it is equipped with double temperature sensors. This keeps the heat in place and ensures and even temperature throughout the entire oven. The result is both lower energy costs and better baking results. Easy opening and closing, with the robust door structure supplied with decent auxiliary suspension. The stainless, sandblasted handles stay cool and are pleasant to touch. There are two robust, pull-out shelves as standard. Please read the section containing baking tips so you can get the best out of the oven. The P-Series high temp is available with one or two decks. The oven with two decks has one high temp deck and one deck for temperatures up to 6620F (3500C). -P601HT-N One deck high temp (up to 9320F (5000C)) -P602HT-N Lower deck: up to 6620F (3500C) Upper deck: up to 9320F (5000C) 7 Operation Maintenance Installation P600HT-N 860251-02 P-Series 601HT-N Approx . weight lbs (kg) without stone with stone 565 (257) 660 (300) Height, door opening 5,51" (140 mm) Ventilation 3500-4400 cu ft / hour (100-125 m3 / hour), Ø4,92" connection (Ø125mm) Cable 11,5 feet (3,5m) cables are included for all ovens.

The leg section comprises four legs, each of which is secured to the base by means of four screws. Electrical connection 11,5 feet (3,5m) cables are included for all ovens. Part number 60471-800 Entrelec 11513916 35mm2 4,5Nm Fuses The oven is fitted with built-in miniature circuit breakers situated inside the openable panel door, where they are readily accessible. There is also a glass fuse here (6,3A, 5x20mm) for illumination of the oven chamber. If the oven overheats, a miniature circuit breaker is tripped via the oven's overheat protector (see the section entitled Troubleshooting). Element Control Lighting Buzzer (only Premium) 10 Operation Maintenance Installation P600HT-N 860251-02 Ventilation The ventilation holes around the oven must not be covered. If the oven is built into a wall, this space must be ventilated so that the oven's electrical equipment is not damaged. The ambient temperature for the oven must not exceed 122 °F. When the oven is built in, it is important to ensure that there is at least 2" between the oven and any flammable construction elements. Bear in mind that the ventilation holes on the oven's front underside may not be blocked when installing on a bench or if the oven's own stand is not used. Evacuation The P-Series is designed for connection to an evacuation duct with mechanical ventilation. The oven is ready for connection to a Ø5" evacuation duct. An appropriate extraction volume is 3500-7000 cu ft/hour, depending on the size of the oven, see section Dimensions. The evacuation air temperature is approx. 104-113 °F. If the oven is connected to an evacuation with natural ventilation, the oven's vent hood will be unable to remove odours and smoke from the oven chamber as efficiently. Heating The oven has a built-in Turbo function which allows it to reach the set temperature in the shortest time possible. This function is enabled and disabled fully automatically if necessary. 11 Operation Maintenance Installation P600HT-N 860251-02 Panel General description Actual temperature Temperature setpoint 245 250 Panel on/off button Alarm button Increase/decrease button for temperature/power mode Button for power mode, front heat Button for power mode, top heat Button for power mode, bottom heat 12 Operation Maintenance Installation P600HT-N 860251-02 Oven off of f The panel shows OFF and all its functions are switched off.

In large measure, the challenge is in learning how the heat behaves in the stone, with its high thermal inertia, and, bearing this in mind, setting the oven and working in the right way. The oven is split into 3 heat groups. Top, bottom and front heat. All of them can be regulated from 0-10, where 0 means 0% power (completely switched off) and 10 means 100% power · The top heat primarily regulates baking the top of the pizza · The bottom heat primarily regulates baking the bottom of the pizza · The front heat regulates the baking towards the door A good basic setting to start with, looks like this: Front Top Bottom Temperature Low intensive baking 8 8 1 545°F Moderately intensive baking 9 9 3 572°F High intensive baking 10 10 6 590°F The bottom heat must never be set to 0! When only the top heat is working, it heats up the upper layer of the stone very much, which, in its turn, burns the bottom of the pizza. So, by setting the bottom heat to approx. 1-2 instead, you obtain a paler bottom and a more stable and balanced oven. It is important to work in a structured manner in order to obtain uniform results the placing of the pizzas is important. Because the stone has a natural inertia when absorbing heat, you should give the stone a couple of minutes to recover before placing a pizza on the same spot again. This is best done by thinking of numbered locations in the oven, where you place the first pizza in location one, a second in location two and so on, when you have used all of the locations you start from location one again. If you have more than one deck, you can rotate through even more locations as needed. If the stone even so does not recover between pizzas, you need to increase the bottom heat. It is also important not to bake a pizza in one location and then place the next pizza partly overlapping where the previous pizza lay. In which case, the pizza will lay partly on hot stone and partly on cooled stone and, has a result, the pizza will be very unevenly baked. During moderate and high intensive baking, the damper can be opened to release some of the steam formed during baking through the rear section of the oven, this reduces the steam that comes out through the door. During low intensive baking, the damper should be kept closed for the minimum energy consumption. 21 Operation Maintenance Installation P600HT-N 860251-02 Pizza High Temp Tips when baking Neapolitan pizza: · The flour should be finely ground and have a high protein content and low fibre content. "Tipo 00" is the best kind to use · Sea salt should be used · Sugar should not be used in the dough as this increases the risk of burning the base · A long proving time should be selected approx. 24 to 48 hours · The dough should be warmed up in the oven before baking. This results in an airier "cornicione" and reduces the risk of burning the base · The baking time is normally 60 to 90 seconds at a temperature of approx. 887 degrees Fahrenheit · The higher the water content in the dough, the higher temperature you can usually bake it at This is a typical recipe for Neapolitan pizza dough: 35,3 oz. 22,9 oz. 1,2 oz. 0,05 oz. Tipo 00 flour Water Sea salt Fresh yeast The recommended basic settings for the oven are: Low intensive baking Front 7 Moderately intensive baking 8 High intensive baking 9 Top 6 7 8 Bottom 1 2 3 As regards the temperature, we recommend the following based on how much water you have in the recipe in relation to the amount of flour used. However, we recommend that you always start on max. 375 degrees until you have got to know the oven. 50% water 60% water 75% water Temperature 707°F 797°F 887°F 22 Operation Maintenance Installation P600HT-N 860251-02 Troubleshooting If any kind of problem occurs, you should first look through the troubleshooting list below to see whether you can rectify the fault yourself. If this does not help, please contact the Sveba Dahlen service department. Note: You are not permitted to work on electrical components yourself. This work must be undertaken by a qualified electrician. Fault Cause Action The oven does not start. · The oven's fuse may have tripped. · The main fuse may have tripped: The oven temperature falls, or the oven takes a long time to return to temperature. The top of the product is too dark. · The damper is open. · A fuse/overheat protector may have tripped. · An element may be broken. · Too much top heat. The underside of the product is too dark. The top and underside of the product are too dark. · Too much top heat. · To high heat. · Baking temperature too high. · Baking time too long. · Too much top heat.

For this reason, direct the chilled air away from the oven. 23 Operation Maintenance Installation P600HT-N 860251-02 Maintenance Cleaning Cleaning your oven thoroughly will extend its service life and also give your customers a better impression. The oven chamber should be cleaned every day, for reasons of hygiene. Do not use steel wool or other cleaning sponges. Do not use scouring powder or detergents which are aggressive or cause scratches on the oven's glass doors. Remember not to use cold cleaning fluids on hot glass as this may possibly crack the glass. You must be able to touch the glass with your hand (max. 122 °F) to be able to clean it. Glass doors which are rarely or never cleaned will become very difficult to clean. The stones in a P600 High Temp are cleaned by heating the oven to its maximum temperature for about one hour. This causes residues burnt onto the stone to burn off, and these can then be swept away using a natural fibre brush (not metal) so as not to damage the stone. Daily cleaning 1. Allow the oven to cool. 2. The stone. Brush the stone clean using a natural fibre brush (not metal). Burnt on residues can be scraped off using a metal scraper (take care not to damage the surface of the stone). The stone used in the P600 High Temp must be cleaned using the process described above by setting the oven to its maximum temperature and only using a natural fibre brush (not metal). Note: water and detergent must not be used on the stone! 3. The glass door. Wipe with a damp dishcloth and a little washing-up liquid, or use an appropriate detergent. We recommend Brilliant Clean, part number 80064-005 (follow the instructions on the bottle). Note: the glass must be below 122 °F when cleaning it. 4. External cleaning. Wipe all external surfaces, including panels, using a damp dishcloth and a little washingup liquid. We recommend using Steel-Care, part number 91430-009, for the stainless surfaces. Every 4 to 8 weeks/As required We recommend Oven Cleaner, part number 6866-103180, for cleaning heavily burnt-on stains on/in the oven. Can be used on glass and metal (but not on aluminium). Note: this detergent is very strong. Take care to use the correct protective equipment, and do not get the detergent on the stone, the gasket or the panel! 1. Allow the oven to cool. It must be below 122 °F. 2. Put on rubber gloves and protective goggles. 3. Cover the dirty surfaces with Oven Cleaner. 4. Leave it to work for 5 to 15 minutes, depending on the thickness of the layer of burnt-on dirt to be removed. 5. Wipe with a wet sponge/cloth. Clean double glass / As needed Dismantling and removing the glass from the glass is easier if there are two people. You need: Socket for hex screw, size 8 mm. Glass cleaner. Towel 1. Open the door and unscrew the screws holding the glass unit to the inside of the door. The person helping holds their hands under the glass to stop it from falling down. 2. Lay the entire unit, glass pieces with sealing rings and metal frame, on a clean table and, preferably, on something soft, e.g. a towel. 24 Operation Maintenance Installation P600HT-N 860251-02 3. Clean the glass pieces with a small quantity of cleaner. Take care to note which glass was placed innermost and which side of the glass faced into the oven. The glass pieces have to be in the same position when they are reassembled. 4. When the glass pieces have been cleaned, reassemble the glass unit on the table. 5. Lift and reassemble the glass unit in the door. Note: The oven must not be flushed with water as this may result in short-circuiting and cause corrosion damage to parts of the oven which cannot be seen. Do not use a high-pressure washer. Do not use a high-pressure washer Electrical cabinet The main power supply must be switched off before carrying out any servicing. Use a soft brush to clean the cables and components in the electrical cabinet. Take care when using a vacuum cleaner in the electrical cabinet as this may generate static electricity which may destroy the electronics in the data panel. 25 Operation Maintenance Installation P600HT-N 860251-02 Replacing the oven chamber lamp, type LED (P Series HT) First, switch off the oven! Access the LED lamp by undoing the screw and turning the service panel on the outside of the oven. Service panel LED lamp There is an LED lamp at the end of the LED luminaire. To replace it, first pull out the plug to the lamp. Next, detach or break off the hooks at the top and bottom of the lamp. Use the tool supplied with the oven for ease of access to the hooks. When the hooks are detached, pull the LED straight out. Tool Hooks Install the new lamp by snapping it into the luminaire and connecting the plug. 26 Operation Maintenance Installation P600HT-N 860251-02 Servicing The oven must be serviced at regular intervals for the warranty terms to remain valid. A service programme indicating service intervals is provided below.
