important safety instructions Please read this instruction carefully! Only then can you operate your device safely and correctly. Keep the operating instructions for future use. Check the device after unpacking. Do not connect in case of transport damage. This device is intended for home and home use only. Use the device only for pest control of wood-destroying insects. Oversee the unit during operation. Only use the device indoors. Keep children up to 14 years away from the device and the connection cable. Risk of fire! The device gets very hot. Also, the woods to be treated are very hot. Observe the minimum distance above and beside the device in the chapter Setting up and connecting. Make sure that there are no residues, resin or similar on the front panel made of polystyrene or have formed. Scrape off such dirt with a sharp knife. Do not use solvents or solvent-based cleaning agents. The improper use of the device is dangerous and can cause damage. Danger of serious damage to health! Never operate the device without aligning it with the wood to be treated. For very small beams or boards fill the designated treatment area with additional wood, as otherwise unacceptably high and dangerous microwave potentials can occur in the room, see also chapter Exposure areas.



Version20190521

Electric shock! Improper repairs are dangerous. Only one of our trained service technicians is allowed to perform repairs and replace damaged power cords. If the device is defective, pull out the mains plug. Combustion danger The device gets very hot. Also, the wood to be heated is very hot. Allow to cool after use. Keep children away. Scalding! Due to the heating up of the wood, boiling steam can cause hot steam and spray steam bubbles, even if the appliance is switched off again. This also applies to any dissolved resin in the wood. Keep distance. Keep children away. Risk of injury Stellen Sie das Gerät immer auf geeigneten und festen Untergrund auf, damit es nicht umfallen kann. Eventuell mit Spanngurten verzurren, jedoch die gekennzeichnete Behandlungsfläche nicht abdecken. Preparation for microwave use On the device is the treatment surface, which is covered with a white rigid foam plate from which the microwaves, hereinafter referred to as μW, emerge. The effective treatment area (dashed line) when looking at the front of the device is approx. 21 x 33 cm:



Version20190521

It is very dangerous to expose yourself or others to this area of μW! For safety, there are additional notes on the sides of the housing:

Danger due to microwaves! To ensure success, you need to measure the temperature in the least favorable places. These are for unilateral treatment, the red circles marked: For two-sided treatment these are these areas: Note that it will not do you any good if you "overheat" one area and do not heat the other area enough. Furthermore, the buoyancy has a significant impact, which means that you are more likely to position the device slightly below the middle of the beam. Only if you reach the lethal temperature in the entire cross-section, you can be sure to have successfully fought the infestation. During operation, the measured temperatures are not exact because they are corrupted by interferences of the μW. So to be able to measure accurately, you must switch off the device. However, the measurement error during operation is relatively the same, so you can also see in operation, if the device is optimally positioned, d. H. the critical temperatures are even. For this reason, drill 4 holes, whether straight or inclined, into the most unfavorable areas and push in temperature sensors. The depth of the holes depends on the accessibility from the outside. With free access, 1 - 2 cm is sufficient. Make sure that the tip of the probe is also in contact with the wood. Fix the sensors, eg. B. with matching wooden dowels (not included).



Version20190521

If you want to use unshielded sensors, drill holes with a diameter of 2 - 3 mm, shielded cable sensors require a diameter of 6 - 8 mm. Note, however, that the meters offered for this purpose only measure reliably when no μW are in operation and, in the case of measurements with μW operation, the interference error of unshielded sensors is still considerably greater than shielded versions. If you treat thick beams (> 18 cm thick), it may happen that temperatures> 100 ° C occur on the treatment front or the wood discolors and changes its structure at temperatures> 120 ° C. Then it makes sense to also put temperature sensors on the front, which you can attach with a U-shaped (office) clip. It may then be necessary to interrupt the μW operation for a few minutes until the front temperature has fallen below 100 ° C again, and then possibly reheat it intermittently until reaching the lethal temperature at the most unfavorable points. For even more powerful beams, we also come to the limits of use of the device, so we recommend for dimensions above 20 cm of oak or 23 - 25 cm of softwood 2 devices opposite to arrange, as shown in the sketch of the previous pages, because of the limited power of the device (s) of the beam can not be heated with economic effort in its entire cross section. At 30 cm or even more, even more equipment may be required, but these can no longer be assigned to household-like use and therefore can be left to professional pest controllers. According to DIN 68800, the safe lethal temperature for all insects is 55 ° C for 1 hour. However, these treatment parameters are based on previous hot air treatments, in which the temperature could be supplied only slowly via heat conduction from the outside. In fact, these function parameters are dependent on temperature and time. So you can also z. B. at 60 ° C and 30 min. Holding time succeed or 65 ° C and 10 min. or 70 ° C and 2 min. However, we recommend adhering to the recognized technical rule according to DIN68800 (55 ° C 1 hour). To ensure this with μW technology, it is sufficient to heat the thermally insulated beam to about 65 - 68 ° C. Then, with the insulation left, the beam cools to around 55 ° C within one hour and so far there have been no complaints with this procedure. But no rule without exception: In our experience, the splint wood beetle (Lyctus) does not follow the DIN. Since this beetle originally comes from the tropics, its lethal temperature is 66 ° C. Therefore we recommend to fight this beetle with 70 ° C.



Version20190521

If the two lethal temperature sensors deviate significantly (> 5 ° C), the device can be better positioned and the duration of treatment reduced. Through appropriate plain text information, the measurement protocol is also reproducible to the unavailable. For documentation, we recommend the following measurement protocol.

Version20190521

Treatment of beams The insulating material is primarily hard foam (polystyrene), which is virtually no resistance to μW. For bulky beams, glass wool has also proven itself because it is more flexible. Even small slits in the insulation of 1 - 2 mm cause considerable heat losses and should be avoided. To close such slots is silicone or PU foam. But then please avoid direct contact with the beam. Insulate the beam to be treated with approx. 3 cm thick foam boards. You can also easily fix the plates with nails. However, avoid nails in the direct area of treatment. You do not need to insulate in the area of the treatment surface, as the front panel of the device simultaneously ensures insulation. For round bars we recommend glass wool mats. If the beam is between a wall, the wall can also serve as insulation. Align the device with the front directly on the beam to be treated. If necessary, position the device securely on boards or planks or on a tripod with a suitable substructure and fix it with tension straps, which, however, should not protrude into the treatment area. But before we start treatment, we still have to look at risks, namely the hazard and exposure areas explained below.

Danger and exposure area The employers' liability insurance association has issued the regulation and guideline'Electromagnetic fields' (BGV B11 and BGR B11). Even if you have nothing to do with the professional association as a private user, we take this rule because it serves for your safety. We have compiled the relevant values for you from these documents: Accordingly, the permissible limit value is a permanent exposure in the area of increased exposure and exposure range 1: 5 mW / m² = 50 W / m² in the exposure range 2: 1 mW / cm² = 10 W / m² Definition of the areas:



Version20190521

To give you a sense of the μW residual potential, some comparative data: When you make a call with your mobile phone, the 5 mW / cm² at the ear are usually exceeded. A long-term study (> 10 years) in high-frequency laboratories in the US found that sustained exposures of 100 mW / cm² did not cause any detectable damage or alteration to humans and animals. For medical μW applications, eg. For example, to relax back muscles people are being treated at 500 - 1,000 mW / cm² and they are doing well. (The doctors do not have to adhere to the regulations of the professional association of precision mechanics and electrical engineering!).

Setting up and connecting This appliance is intended for home and household use only. Place the device on a firm, even surface and align it directly in front of the wood to be treated. Never run the device empty without wood or wall in front !!! The ventilation slots on the back, top and bottom must always remain free.

If there are heat / temperature differences in the game, then you also have to consider the buoyancy. In fact, this is noticeable. When heating from the top you need considerably longer than when heating from below. With side heating we still have differences of 10 - 20%. Consequence: Bars are treated more efficiently from below. For lateral heating, it is better to position the device axis approximately 10 - 20% below the center of the beam. moisture content The influence of wood moisture is relatively low. Although we need a certain minimum moisture content (> approx. 1 - 2%), so that μW can be absorbed at all, but this moisture is practically always present. However, the thermal conductivity of wet wood (> 20-30%) is better. In this case, more heat flows into colder regions, but this is relevant only in the first heating section and in total means no additional losses. The loss of moisture during a μW treatment is also relatively low and is about 2-3% on average for dry beams (<approx. 10 - 12% wood moisture content) if treated optimally. With quite thick (> 18 cm) and new beams (wood moisture at approx. 30%), which can only be treated on one side and thus the treatment can sometimes take several hours, the evaporation is also greater. Since we have already measured 5 - 10% lower wood moisture after treatment than before the treatment. Colors and paintings According to previous experience, no changes / discolorations were found in the paints encountered. For unknown colors, however, we recommend that you consult the manufacturer about the temperature resistance; if necessary, test the temperature resistance on a sample or as far as possible on the minor side. The device is ready to plug in and may only be connected to a properly installed earthed socket. The fuse must be at least 10 amps. The mains voltage must correspond to the voltage stated on the rating plate. The laying of the socket or the replacement of the connecting cable may only be carried out by a qualified electrician. The appliance plug must always be accessible.

Worth knowing about microwaves Adjust as described in points 1 to 3.



Version20190521

Microwaves convert their energy directly into matter, in the wooden beam into heat only, which is the ultimate kick of microwaves. Therefore, the temperature inside the wood is higher than outside, in contrast to conventional control methods such as hot air, where the temperature from the outside can flow only slowly via the heat conduction to the interior of the wood. Without after-effects after shutdown. It's like the light switch: it's dark immediately after turning off the light. penetration depth Theoretically, the penetration depth is infinite. In practice, however, about 50% of the power is absorbed at each wavelength (12 cm). Therefore, we recommend one-sided treatments only for wood thicknesses up to 18 cm. For larger cross-sections, it makes more sense to treat from 2 sides or use 2 devices at the same time. Furthermore, the buoyancy plays a certain role. When you work from below, placing the device under a beam, you work with the buoyancy and are more efficient than if you act from top to bottom, ie against the buoyancy. In addition, the internal μW components are subjected to more thermal load and thus the service life is reduced. If vapors form within the wood, which then condense again on colder areas, behind or beside the main field, thermal stresses and cracking can occur. To avoid this, you should not exceed 100 ° C. Note that embedded resin can also become fluid at these temperatures and then primarily concentrate on branch attachments. If the wood is rotten or already eaten, the heating will be faster because the density / mass is much lower. If there is still "loose" milling or drilling dust in the interior of the beam (only), the ignition temperature can be exceeded. It can even cause a smoldering fire. Avoid temperatures above 100 ° C. Furthermore, at temperatures close to and above 100 ° C, the device front panel made of hard foam deforms. However, this is not a defect of the device but only a cosmetically unsightly concomitant and no functional disturbance or impairment of safety. Just take a few minutes breaks. Then the heat from the near-surface areas is dissipated further to the rear and you can then re-heat when the critical (near-surface) areas under again



Version20190521

the level you want. Although this extends the treatment time, but you can also lower maximum temperatures, eg. B. 80 ° C comply. Even if only 60 ° C is allowed for sensitive colors, this can be ensured with intermittent operation. You can check the surface temperatures with an infrared thermometer when the unit is turned off. See our accessories list for suitable devices that are very μW-sensitive. Never measure with these devices when operating the μW device. μW penetrate glass, porcelain, paper, ceramics, air without significant resistance (damping). On metal surfaces, no matter how thick or how they are procured in the surface, ie polished, polished or painted, even if copper, brass, aluminum, steel, stainless steel, galvanized, the μW are reflected. Again, no rule without exception. When μW is applied to a thin and long metal rod, it can become a rod (dipole) antenna. Then it no longer reflects the μW but absorbs it and converts the energy into heat, so it gets hot. That depends on the diameter and the length of the bar and the wavelength. This can affect nails or screws that are in the wood or even protruding. In practice, however, this has so far only occurred in headless steel pins, which are usually attached Boden¬randleisten. These nails are usually 3 cm long (λ / 4) and smaller than 1 mm in diameter. In this case, pay particular attention to possible overheating. All other commercial dimensions of nails and screws are too thick in relation to length to assume this phenomenon and thus can not cause problems. Hot Spots These are unreproducible, regional bundles of microwaves and unfortunately can not be avoided. As a result, certain areas in the wood are heated more. However, due to the natural heat conduction, the temperatures and their environment are equalized again, so that there are hardly any measurable differences in practice and these 'hot spots' are barely noticeable. Like all electromagnetic waves, μW also affect other similarly powered devices. These include electronic or magnetic devices such. As radios, TVs, PC's including their remote controls and connection cables, speakers, radios, "phones", magnetic memory cards, z. B. check or credit cards. Please relocate such items from the rooms to be treated to the safe exposure area 2. Any claims



Version20190521

alleged or actual defects on these devices are excluded! Therefore, the corresponding safety instructions of these devices must be observed. People with pacemakers are not allowed in exposure area 1. Since it can not be ruled out that you may spend a short time carelessly in the exposure area, the device must not be operated by people with pacemakers. However, before putting the μW device into operation, make sure once again that you have made all preparations. In particular, this includes estimating the expected exposure range 1 if the area behind the beam or parquet to be treated is not open or can be viewed. Make sure what's behind it. If the z. For example, if you have another apartment, inform the neighbors and close the room to make sure that during your μW treatment there is no B. can stop a baby. If necessary, you will need to refrain from treatment or take shielding measures if you can not resolve this before startup. Mark the appropriate areas eg. For example, with warning tape and warning signs, or put the control unit clearly visible in front of the access point, as it also the μW operation is displayed. Your personal permanent control also ensures that no unauthorized persons (eg with pacemakers) have access to exposure area 1. Then document your measurements and measures in the measurement protocol.



Version20190521

Furthermore, before the hazardous area, as a precaution, it is better to set the warning sign in front of the access to exposure area 1:



Version20190521

Do Not Enter ! Behind this barrier

Danger due to microwaves!



Version20190521

Print out this warning label and stick it on a cardboard or wooden board to mark the area described above. If you have also secured these premises, go to the exposure area 2 with the control panel and press the start button to go directly to the metrological tour: Metrological tour After commissioning, move out of the safe exposure area 2 in the direction of the μW device and measure until you reach the limit of 1 mW / cm². Move the meter up and down with the front of the μW unit to detect any hot spots. Define the exposure area 1 around the entire area behind and to the side of the μW device. At the safe distance, move to the front and measure the exposure limit 2 limit. That may be in the neighboring apartment! If there are areas that exceed the threshold, there is nothing left but to safely shut off or shut down this area until you find another solution. Furthermore, with the extended limits, there are <5 mW / cm² = 50 W / m² and <6 min in the exposure area 1 and <30 mW / cm² = 300 W / m² <6 min. in the area of increased exposure, safe limit values for your metrological tour (see section 9, Commissioning), where our desired exposure area 2 may briefly become exposure area 1 if you notice areas of increased exposure. Excessively high measured values are not to be classified as dangerous!
