Frequently Asked Questions - Design Advanced Scale Pro 46014 Gastroback

Why is my vacuum sealer not sealing the bag?

Common causes: The bag is not positioned correctly (the open end must lie flat on the heating bar and reach into the vacuum chamber), the sealing strip is dirty or wet, or the appliance has overheated. Clean the sealing bar, ensure the foil is dry and wrinkle-free, and allow the appliance to cool for at least 60 seconds between cycles.

The vacuum pump runs but the bag doesn’t evacuate. What should I do?

Check that the locking pins on both sides of the lid are inserted fully and click into place. Also verify that the drip tray is installed correctly (the higher bar facing the hinges). If the bag still doesn’t evacuate, the bag may be damaged or not airtight – try a new bag.

How do I use the scale function?

Screw the scale platform onto the scale installing port. Connect the appliance to power. Press the MODE button to select unit (g, oz, lb). Place the item on the center of the platform. To tare a container, place the empty container on the scale, press TARE, then add ingredients. Do not exceed 2 kg total load.

Can I vacuum seal liquids or moist foods?

Yes, but select the MOIST setting using the FOOD button. For very moist items, pre-freeze partially or use the GENTLE speed. Always leave at least 5-8 cm free space at the top of the bag. If liquid reaches the sealing area, stop immediately and dry the bag rim.

How do I clean the drip tray and the vacuum chamber?

Unplug the appliance. Remove the locking pins and open the lid. Take out the drip tray and wash it in warm dishwater. Wipe the vacuum chamber, sealing bar, and vacuum gaskets with a soft, damp cloth. Do not use abrasive cleaners or immerse the appliance. Let everything dry completely before reassembling.

What does the VACUUM MARINATE function do?

This function runs a 20-minute cycle of alternating vacuum and venting to quickly infuse marinade into food. You need a compatible vacuum container with a manually adjustable pressure valve. Connect the vacuum hose from the appliance to the container lid, open the valve, and press and hold the VACUUM MARINATE button for a few seconds.

Why does the scale show 'o_Ld'?

'o_Ld' indicates overload. The total weight on the scale platform exceeds 2 kg (2000 g). Immediately remove all objects to avoid damaging the scale sensor.

Can I use any plastic bag for vacuum sealing?

No, only use bags or foils specifically designed for vacuum sealers. Ordinary plastic bags may melt or not form an airtight seal. The appliance accepts foil up to 290 mm (11.5 inches) width. Use the SEAL function to create custom-sized bags from the foil roll.

How do I calibrate the scale?

Calibration requires a 2 kg calibration weight (not included). Press and hold TARE and MODE simultaneously until '2000.0 g' appears. Place the 2 kg weight on the center of the platform. After a few seconds, 'PASS' confirms calibration. If you don’t have the weight, press STOP immediately to exit.

What is the warranty period and how do I claim?

The appliance comes with a 2-year warranty covering manufacturing and material defects. Keep your sales slip as proof of purchase. For claims, send the appliance with a brief fault description to the address provided in the manual. Incorrect use or unauthorized repairs void the warranty.

Do not operate the appliance, when the appliance or any part of it is likely to be damaged. Damaged or unsuited parts could cause injuries and damage due to overheating, implosion, and electric shock.
• Regularly check the appliance and power cord for proper operation. The pins of the plugs and power port at the back of the appliance must be smooth and clean without any discolouration.
• Return the appliance to an authorised service centre for examination and repair, if the appliance is not working properly or overheating, or was subject to inadmissible strain (e.g. overheating, mechanical or electric shock, moisture). Do not operate the appliance, when any part of it is not working properly. Unplug the appliance immediately, when a severe problem occurs during operation (e.g. water is sucked

into the vacuum pump, overheating). Do not attempt to open or repair the appliance on your own. Any operation, repair and technical maintenance of the appliance or any part of it (e.g. exchanging any permanently mounted parts) other than described in these instructions may only be performed at an authorised service centre. Please contact your vendor.

• Operate the appliance on a well accessible, stable, level, dry and suitable large table or counter. During operation keep the appliance in an appropriate distance of at least 10 cm on each side to other objects. Keep at least 50 cm of free space in front and above the appliance for free access.
• Do not place any clothes or tissue or other objects under or on the appliance during operation, to avoid risk of fire, electric shock and overheating. Do not place the appliance or any part of it on or near hot surfaces (e.g. burner, heater, range, or oven).
• Do not place any hard, sharp-edged, or heavy objects onto the appliance to avoid damage to the appliance. The integrated scale will bear a maximum load of 2 kg. To avoid damage to the scale: Do not place any objects on the scale platform weighing more than 2 kg in total, including any weighing vessels/package (tare) and the contents. If in doubt, use another suited scale to check the rough weight of the object first. Do not leave any objects uselessly on the scale platform. Remove the scale platform from the scale installation port, before transport or storage of the appliance to maintain the accuracy of the scale sensor and avoid damage.
• While using the scale, ensure not to touch the contact bar. The contact bar will open the lid automatically, and any material on the scale platform could fall over.
• Before starting a sealing session, ensure that the drip tray in the vacuum chamber is completely empty (see: 'Emptying the Drip Tray').
• Keep in mind that the heating bar and sealing bar will get hot during operation. Do not touch the heating bar and sealing bar with your hands or any delicate objects shortly after operation.
• The vacuum sealer is intended for evacuating and sealing the designated foils, bags, and vacuum containers only. Insufficient or dama-

ged vacuum containers may burst (implode) when evacuated, leading to a high risk of injuries and damage according to splinters and splashes being hurled about. Before evacuating vacuum containers, always check the containers for any type of damage (e.g. cracks, distortions, or dents). Unsulted foils, and bags could cause overheating, and fire, or stick down to the sealing bar or heating bar. Do not overfill the bags or containers to avoid damage and overheating due to any substances, sucked in during operation. Do not place any foreign objects into the appliance. Always handle any evacuated containers with special care to avoid injuries and damage due to implosion, hurling splinters and splashes about. Do not expose evacuated containers to heat or mechanical or thermal shock or direct sunlight.

• Risk of Explosion and Fire! Do not seal or evacuate containers or bags filled with inflammable, volatile substances (e.g. spirits, organic solvents)!
• Do not use violence, especially when attempting to open the lid! There is an automatically operated lock, closing and opening the lid during and after operation (see: 'Properties of Your New Design Vacuum Sealer Advanced Scale Pro').
• Do not use abrasive cleaners or cleaning pads for cleaning the appliance or any part of it. Do not clean the appliance with any corrosive chemicals (e.g. bleach). Do not use any hard or sharp-edged objects for operation or cleaning. Always handle the heating bar, sealing bar, and vacuum gaskets with special care. DO NOT place the appliance or any part of it in an automatic dishwasher. Never re-use bags and containers for any foodstuffs, after storing foreign objects within them, because harmful substances (e.g. mineral oil, lubricants, solvents) could infuse plastics or build an invisible microscopic layer on plastic surfaces, that persists even after thorough cleaning, contaminating your food with foreign odours and toxic substances.

IMPORTANT SAFEGUARDS FOR ELECTRICAL APPLIANCES

- Ensure that the voltage rating of your power supply corresponds to the voltage requirements of the appliance: 220 - 240 V, 50/60 Hz, AC, rated for at least 8 A. The installation of a residual current operated cir-

cuit breaker (r.c.c.b.) with a maximum rated residual operating current of 30 mA is strongly recommended. If in doubt, contact your electrician.

• Only connect the appliance via the designated power cord to the mains power supply. Do not use any power cords other than recommended by the manufacturer.

PROPERTIES OF YOUR NEW DESIGN VACUUM SEALER ADVANCED SCALE PRO

Note

The operating elements of the appliance are touch sensors. There is no need to press on the buttons but only lightly touch them.

The following operating elements are provided.

Function Usage
VACUUM SEALING
Contact baron the front side of the lid	With the appliance live, touch this metallic bar for opening and closing the lid. The contact bar will be inactive, while a sealing or evacuating process is running.However, the appliance will open and/or close and lock the lid automatically during and after operation. On the LCD display an appropriate message is shown, whenever the lid is moved: “OPEN” or “CLOSE”.CAUTION: Do not attempt to open or close the lid violently!For moving the lid manually, the locking pins at the sides of the lid must be removed first.However, for sealing and evacuating bags, the locking pins must be installed correctly(see: ‘Operation / Emptying the Drip Tray’).
SEAL	For sealing bags and foils only.Via the SEAL function, you can seal foils and bags without evacuation. Use this function for making your own bags of individual size or for sealing bags airtight but under normal pressure.
Vac SEAL	For vacuum sealing air-tight bags only.Before sealing, the appliance will remove the air from the bag, causing the foil close-fitting to the contents of the bag.The appliance will reduce the pressure within an air-tight bag by at least 0,6 bar.The evacuating time will depend on the setting of the SPEED function, the size of the bag, and the contents.
SPEED	Using this button, you can toggle between 2 different speed settings: NORMAL and GENTLE. An LED will indicate the currently set speed.In most cases, the pre-set NORMAL speed operation is suited for vacuum sealing dry, solid, and tough food. With delicate, very moist, or fine-grained objects and small bags, the GENTLE speed may be better. Via this setting, the vacuum pump will be operated at reduced power.
FOOD	Press this button to select the type of food or object, you wish to vacuum seal:MOIST food containing a lot of liquid, or DRY food or solid objects. An LED will indicate the current setting.
VACUUM MARINATE	Use this function for evacuating containers and for vacuum marinating.·Shortly press the button to start evacuation of a vacuum container.·To enter the MARINATE function, press the button for some seconds until the vacuum pump starts working audibly and vertical bars are shown on the LCD display (see: 'Marinating').Vacuum containers are perfectly suited for marinating foods in a short time. This is because the micro-holes of the foods are opened under low pressure, allowing pickle infusion very quickly. Using this function, during 20 minutes the appliance will run cycles of evacuating and ventilating the container. This way, foods will get optimum marinade infusion in the least time duration. Additionally, due to the especially short marinating time under low pressure, the growth of germs within your food during marinating will be minimized.The designated vacuum tube and a suited vacuum container is essential for using these functions. Additionally, for vacuum marinating, a manually adjustable pressure valve on the container lid is required. Ensure that the pressure valve is set to "OPEN", before starting the marinating process.IMPORTANT: To prevent germs from getting into your food, it is good advice to sterilize the vacuum container and container lid before filling in food.
Stop	You may cancel any sealing or evacuating process at any time you wish by pressing the STOP button. The appliance will immediately stop operation and ventilate the vacuum chamber or container.NOTE: If you wish to terminate evacuation but seal the bag with the low pressure already achieved, press the SEAL button. If you wish to terminate the evacuation of a container with manually operated pressure valve at the already achieved pressure, simply close the pressure valve of the container.
Weighing
Button	Usage
MODE	Press this button for selecting the unit: "g", "oz", or "lb".
TARE	Tare function: subtracting the weight of the vessel automatically. The LCD display will show zero again. Use this function to conveniently weigh your ingredients in vessels or add further ingredients (see: 'Subtracting the Weight of the Vessel').

AUTOMATIC SHUT-OFF

For energy saving, the appliance will shut-off after being idle for more than 10 minutes.

For reactivating the appliance, simply press a button.

TIPS FOR BEST RESULTS

VACUUM SEALING AND FOOD SAFETY

Note

Vacuum sealing is NO substitute for refrigeration or freezing. Any perishable foods that require refrigeration must still be refrigerated or frozen after vacuum packaging. As with any other storage method, food must be checked carefully before storage and, as well, before consumption.

⚠ WARNING: Before placing evacuated containers in the freezer, check whether your containers are suited for freezing (e.g. check for any appropriate icons), because some types of plastics get brittle under freezing temperature conditions. Especially when taking the container out of the freezer, these containers could burst causing risk of injuries and damage according to splinters and splashes being hurled about.

Note

Do not use the designated bottle stopper on plastic bottles. Do not attempt to evacuate highly alcoholic, or carbonated, or sparkling beverages (e.g. lemonade, sparkling wine, spirits). Vacuum packaging extends the shelf life of foods by removing most of the air from sealed bags and containers, and additionally preventing air and germs from getting into the sealed packaging again. Additionally, vacuum packaging helps inhibiting the growth of a lot of microorganisms. However, please keep in mind that yeast and some types of bacteria (e.g. the highly toxic botulism causing bacterium) can grow even without air. Others produce spores still viable after evacuation.

• In general, bags may be re-used, but do not re-use bags that had been filled with any fatty and/or highly perishable foodstuffs (e.g. meat, sausages, cheese, fish, or seafood). To prevent germs from entering your food, before filling, you should rinse containers or re-used bags with hot water (at least up to 80°C). Check first, whether the container or bag will tolerate the desired high temperature.
• Some types of food contain aromas and colours that infuse plastics and cause persistent odours and discolouration (e.g. red cabbage, capsicum, garlic). Before re-utilisation of bags and containers, you should check whether any odours of the recently stored food persist within the bags or containers.
• For long-term storage, always freeze perishables that have been vacuum packaged. Food packed in bags may be placed in the freezer without hesitation. When using vacuum containers, please keep in mind that some types of plastics will get brittle under low temperature, thus bursting when under low pressure.

GUIDELINES FOR PREPARING FOOD

• Always check up on your food for perfect condition, before sealing and again before consumption.
• Vegetables need to be blanched to stop the enzyme reaction causing loss in quality. Finally, dab dry the vegetables via a kitchen towel before vacuum packaging.
• Some vegetables (broccoli, sprouts, cabbage, cauliflower, kale, turnips) naturally emit gases during storage. Therefore, even after blanching, they must be stored in the refrigerator or freezer only and are not suited for vacuum packaging.

DURING VACUUM SEALING

• Do not overfill the bag. When sealing flat objects, always leave at least 5 cm (2 inches) of free space on top of the bag material to enable evacuation and sealing. With large objects, it is better to leave at least 8 cm (3 inches) of free space above the objects.
• For vacuum sealing large objects, stretch the bag gently flat, while placing it into the vacuum chamber. Additionally, always ensure that the sealing area of the foil is completely dry and clean. Wrinkles, liquids and particles on the foil will prevent airtight sealing.
• When vacuum sealing sharp-edged objects (e.g. bones, spaghetti), protect the bag from punctures. For this you may wrap the objects in paper towel. Alternatively use a container.
• Pre-freeze delicate food that will be stored in the freezer after vacuum sealing. This way the food will not be mashed during evacuation and liquids (e.g. juices) will not be sucked in so easily.
• If the foil material is melted at the rim of the seal, the heating bar may have been too hot during sealing. To avoid overheating, after each usage allow the heating bar to cool down for at least 60 seconds with the lid open.
• If in doubt, whether your bag is really airtight, simply make a second seal.
• To ensure best results, only use foils, bags, and containers recommended by the manufacturer.

HANDLING OF VACUUM SEALED PACKAGES

• Do not heat any vacuum-packed food in the bag. The bag may explode! Additionally, the material of the bags will melt, spoiling your food. Always take your food out of the bag, before heating it.
• Also, avoid heating food within the vacuum containers to avoid spoiling your food and damaging the container. Additionally, vacuum containers could burst when exposed to high temperature. Nevertheless, when using vacuum containers for heating food, always remove the lid first. You may place the container into a bain-marie (pot with hot water) for warming the contents.
• With some vacuum containers, heating in the microwave oven is possible. Before placing your vacuum container in the microwave oven, ensure that the container material is microwave-safe, indicated via the microwave symbol or an appropriate information on the container. Remove the lid, before heating the container. However, to maintain the endurance of the container, it is better to transfer your food into another microwave-safe container for heating, because even microwave-safe plastics will get brittle when exposed to microwave radiation repeatedly.
• Direct sunlight could spoil your food or cause an unappetizing appearance. Also, foils/bags and plastic containers do not tolerate direct sunlight indefinitely. Thus, ALWAYS store foils/bags and containers in a dark, cool place.

STORAGE GUIDE

Important: It is difficulty to predict how long foods will keep their quality, flavour, appearance, or texture with vacuum packaging, because this depends on the type, date of production, and state of the food on the day it was vacuum packaged. Consider the following tables as a rule of thumb.

Food	Refrigerator +3 to +7°C Freezer -16 to -20°C
	Normal Vacuum Normal Vacuum
Meat 2 - 3 DAYS 8 - 9 days 3 - 5 months 1 year
Seafood and fish 1 - 3 days 4 - 5 days 3 - 5 months 1 year
Cooked meat 4 - 6 days 10 - 14 days
Vegetables 3 - 5 days	7 - 10 days
Fruit	5 - 7 days 14 - 20 days
Eggs	10 - 15 days	30 - 50 days

Food	Room Temperature: + 21 to + 25 °C
	Normal Vacuum
Bread 1 - 2 DAYS 6 - 8 days
Rice, flour 3 - 5 months 1 year and above
Peanuts, beans 3 - 6 months 1 year and above
Tea leaves 5 - 6 months 1 year and above

• Always place the objects to be weighed on the centre of the scale platform. Always observe the maximum load of 2000.0 g, to avoid damage to the scale sensor.
• Weighing of liquids is much more accurate than measuring the volume. Use a weighing vessel and the TARE function to eliminate the weight of the weighing vessel, before pouring in the liquid. However, special care is required to avoid spilling liquids on the appliance.
• When weighing large objects, it could be required to use a tray or container. Use the TARE function.
• For weighing powders, seeds, and similar small items, always use a sufficient weighing vessel (container or tray).
• For weighing, you should prefer containers and trays of materials light in weight (e.g. plastic, paper, tin foil), to avoid overloading the scale. Sometimes, for small amounts (e.g. spices), a piece of paper or tin foil is sufficient.

BEFORE FIRST USE

⚠ WARNING: DO NOT let young children play with the appliance, or any part of it, or the packaging!

⚠️ CAUTION: Do not attempt to open the lid with violence! The lid is connected to the locks in the base of the appliance. To open the lid manually, you must remove the locking pins at both sides of the lid.

1. Unpack the appliance and all accessories carefully and check that no parts are damaged or missing (see: 'Knowing Your New Design Vacuum Sealer Advanced Scale Pro').
2. Carefully remove all shipping materials and promotional materials, but DO NOT remove the warning labels or model label. Especially ensure that there are no foreign objects (e.g. packaging) under the lid of the appliance (see: 'Emptying the Drip Tray').
3. Before first use and after a longer period of storage, clean the appliance (see: 'Care and Cleaning').

OPERATION

⚠ WARNING - RISK OF SUFFOCATION! DO NOT let young children play with the packaging material (foils and bags) and/or evacuated containers and bottles. Always ensure that the appliance and all its parts and accessories are out of reach of young children!

⚠ WARNING - RISK OF IMPLOSION! Evacuated containers must always be handled with special care.

⚠ WARNING - EXPLOSION AND FIRE! DO NOT evacuate containers or bags containing any inflammable substances (e.g. spirits, organic solvents)! Under low pressure, large amounts of inflammable liquids will vaporize and build an inflammable atmosphere causing risk of injuries by explosion and fire.

For sealing foils and bags, an electrically powered heating bar is used that will get hot during operation. Avoid touching the heating bar shortly after operation. Do not place any foreign objects on the heating bar. During operation do not place any clothes, napkins, or other foreign objects on or under the appliance.

⚠️ CAUTION: Before connecting the appliance to the power supply, ensure that the voltage rating of your power supply corresponds to the requirements of the appliance.

Only use the power cord recommended by the manufacturer for connecting the appliance to the mains power supply.

CAUTION: Do not attempt to open or close the lid with violence! The lid is moved by the locks within the base of the appliance and is fixed to the locks by two locking pins (see: 'Knowing Your New Design Vacuum Sealer Advanced Scale Pro'). Always avoid to hold your fingers between lid and base of the appliance, when the lid is about to be closed. This will happen, when starting the SEAL or VAC SEAL function or when touching the contact bar.

Important: The vacuum sealer is intended for evacuating and sealing the designated foils, bags and vacuum containers. Insufficient or damaged containers may burst (implode) when evacuated, leading to a high risk of injuries and damage according to splinters and splashes being hurled about. Before operation, always check the vacuum containers for any type of damage (e.g. cracks, distortions, or dents). Insufficient foils and bags may damage the appliance and cause overheating and fire.

After activating the tare function by pressing the TARE button, keep in mind that the total weight of the vessel/packaging plus contents may not exceed 2 kg. If in doubt, check the weight using another course scale. If required, weigh your food in portions.

1. Place the objects to be weighed on the centre of the scale platform. On the LCD display the weight is shown.

2. Remove the objects from the scale platform immediately after weighing, to maintain the accuracy of the scale sensor.

SUBTRACTING THE WEIGHT OF THE VESSEL

For weighing your food in vessels (e.g. liquids, seeds, or flour), the scale can subtract the weight of the vessel (tare) automatically.

⚠ WARNING: Do not spill any liquids on the appliance to avoid risk of electric shock, fire, and damage to the appliance. If liquids are spilled on the appliance, always unplug the appliance immediately, and wipe off spilled liquids. Thereafter, clean the appliance and leave the appliance dry naturally for at least 1 day (see: 'Care and Cleaning').

⚠️ CAUTION: Even when using the tare function, it is crucial to observe the maximum load of the scale. The total weight of the vessel plus contents may not exceed 2 kg to avoid damage to the scale sensor.

1. Prepare the scale for operation (see: 'Preparing the Scale for Operation'). Place the desired vessel on the centre of the scale platform.
2. Wait, until the weight of the vessel is shown on the LCD display. Then press the TARE button. The LCD display is reset to zero.
3. Remove the vessel from the scale platform. The LCD display shows the weight of the vessel with a minus sign. Fill the vessel and place it on the scale platform again. The weight of the contents is shown.

Note

You may pour or spoon your food carefully into the vessel with the vessel still on the scale platform. When doing so, it is crucial not to spill any liquids on the appliance to avoid risk of electric shock and damage. However, if you wish to determine the weight of a portion of ingredients, it is a better way to remove the vessel from the scale platform for filling.

1. If you wish to use another vessel or add further ingredients, then simply place the desired vessel on the scale platform and repeat the procedure beginning with step 2.

2. If you wish to delete the weight of the vessel from the memory of the scale, remove all objects from the scale platform and press the TARE button. The LCD display shows zero.

CALIBRATION

⚠️ CAUTION: Do not attempt to perform calibration without a 2 kg calibration weight at hand! The scale is factory calibrated. Usually, there is no reason for calibration. However, if the scale must be calibrated because of incorrect readings, you will need a 2kg calibration weight. The calibration weight is not provided with the appliance.

Please note that the accuracy of all results displayed by the scale, depend on the accuracy of the calibration. Failure in calibration can reduce the performance of your scale considerably. Thus special care must be taken when calibrating the scale.

By holding the TARE and MODE buttons pressed simultaneously, the scale will enter calibration mode and with the scale platform empty, "2000.0 g" will be shown on the LCD display. If you do not have a 2kg calibration weight at hand, immediately press the STOP button to cancel calibration mode and keep the existing calibration data.

Important: During calibration, always ensure not to touch the contact bar at the lid of the appliance.
