6 4.1 Intended use Instruction manual 4 Technical description The negative pressure unit D305 serves for the filtration of asbestos contaminated air, in temperature rage up +45 C, with external exhaust for the air. During asbestos sanitation works within closed rooms, you must avoid that asbestos fibres quit the sanitation area and in this way endanger humans and the environment. For this reasons, the sanitation areas (also called dirty area) have to be separated from the clean area with the help of a negative pressure unit and kept in dynamic negative pressure. An integrated filtering system establishes the conditions that the asbestos concentration in the exhausted air does not exceed max. 1000F/m³. The exhausted air is blown in the open air. The device is not appropriate for the filtration of flammable gas or dust. 4.2 Unit description NPU to filtrate asbestos contaminated air via a 3-stage filtration unit. The inserted Hepa filter complies with the requirements according to EN 1822 classification H13. By stacking of several devices, minor floor space is needed. smooth and easy-to-decontaminate housing stable and light housing 3-fold sealed hepa filter Hepa filter according to EN 1822 classification H13 very low emission during the change of the filter. Filter change in 3 minutes the filter change is indicated visually via a pressure gauge rustproof and powder coated housing continuously variable control 0-100% (SE and SRE) automatic soft starting, also after a power failure all operation and function elements are shock-protected stackable housing, ergo minor floor space power optimised fan with high capacity Optionen: attachment housing for the second Hepa filter (Double filtration) attachment housing for bag filter acoustical indication for the filter change suction adapter Seite 6

Der Unterdruck wird zwischen Schwarzbereich und einem festzulegenden Referenzpunkt (angrenzende Räume) gemessen und durch kontinuierliche Drehzahlregelung des Elektrolüfters auf Sollwert gehalten. Bei Erreichen der maximalen Ventilatorleistung leuchtet die LED Fan auf. Der notwendige Filterwechsel wird durch die LED Filter angezeigt. LED Filter LED Fan Seite 8

11 4.6 Information regarding the change of filter The frequency of the change of filter depends on the degree of pollution of the filter. If the sealing up of the filter increases (contamination of the filter), the air capacity decreases. For the control of the filter during the operation, the device is equipped with a manometer. Important: Use only approved, faultless filter! The manometer shows approx. 650 Pascal when the filter is new (Evaluated at 100% performance) We recommend a change of filter at approx. 950 Pascal.

15 6 Assembly instructions The negative pressure unit is delivered ex-works and ready for immediate operation. If there are visible damages, do not operate the device. Please contact the deconta GmbH at once. 6.1 Assembly instructions Please respect: Basically the negative pressure can also be operated directly in the dirty area (over pressure technique prevent the infiltration of the surrounding contaminated air in the housing). Because the devices are contaminated from outside and therefore need an expensive cleaning after the end of the sanitation work, one should avoid the use in the dirty area by all means. Connect the device with the wall between clean / and sanitation area Place it about. 100 mm in the sanitation area Seal the device with the wall Conduct the exhausted air hose in the open air Provide for enough supply air in the sanitation area Clean area Contaminated area Supply air opening with self-closing flaps Seite 15

16 Clean area Sanitation area Exhaust hose Attention: Connect the filter housings according to the draft with the ventilation unit and let rise up about 100mm in the sanitation area. Seite 16

17 6.2 Assembly of the optional attachment housing (SNAP) Optionally for a second hepa filter (Double filtration), additional activated carbon filter or pocket filter Dismount the prefilter and unscrew the security corners (if existing) Safety corners Place the attachment housing and fix the tension locks Tension lock Insert the Hepa filter / activated carbon filter Fix the tension frame by means of screws Insert the pre-filter By using an activated carbon filter, this should be inserted in the negative pressure unit and the hepa-filter in the attachment housing.

18 7.1 Control SE Instruction manual 7 Initial operation For the power regulation, the negative pressure unit is delivered in series with a manual continuous variable control. Connect with the current Operate the adjuster Maintenance of the negative pressure in the room Adjust the wished negative pressure at the supply air opening or the continuous variable adjuster Negative pressure too high: open the supply air opening or decrease the device Negative pressure too low: shut the supply air opening or increase the device Seite 18

19 7.2 Control SRE For the power regulation the negative pressure unit is delivered in series with an electronic control, in order to measure and to regulate the negative pressure. The negative pressure is measured between the dirty area and at a reference point to be determined. In order to secure the adjusted values, the control is locked. A LED Fan will beam on reaching the maximal fan capacity, A LED Filter will beam if it is necessary to change the filter Control panel: LED Filter LED Fan Indication 1 Indication 2 Key ON/OFF Key AUTO/MANU Key + Key - Seite 19

20 Starting position: Connect to the current Chose a measuring point in the dirty area and connect the PE-tube 8 x 1 to the negative pressure connection Chose the measuring point in the clean area (adjoining room) and connect the PEtube 8 x 1 to the connection atmosphere Connection Atmosphere connection negative pressure The device is now ready for use. The last memorized negative pressure value will be adjusted automatically. In order to change this value, you may procede as follow: Activate the key ON/OFF Chose the operation mode key AUTO/MANU Automatic - operation The reference value in automatic operation is set with the keys - and + in Steps of one Pascal (reference value in the display Thank2). Thanks to the speed control of the ventilator, the negative pressure is regulated at once automatically. In the display 1 you can see the actual negative pressure. Seite 20

21 Manual - operation Instruction manual In manual operation the power of the ventilator is given with the keys - and + in maximum 7 steps. The display 2 represents this value in % In the display 1 you can see which negative pressure is created with the adjusted power. Important: Im Manual operation, the device does not regulate! 8.1 Maintenace 8 Maintenance The ventilator plants (deduster, industrial vaccum cleaners and devices for the deaeration or kipping in negative pressure) have to be overhauled or controlled once a year at least or if necessary by an expert. 8.2 Filter control During the operation the filter state has to be controlled as described under 4.6. Seite 21

22 8.3 Change of filter Attention: Contaminated filters have to be changed under all corresponding safety measures Filter change only with a machine switched off Use approved filters only Do not use bonding agents on the machine Remove the hepa-filter: Remove the prefilter Unscrew the hexagone screws M8 and remove the tension frame Remove the hepafilter and dispose of it professionally Insertion of the hepa-filter: Control the sealing face of the machine and clean. Clean the inside of the housingi Insert the new filter in the middle Tighten the tension frame and the hexagone screws M8 (tighten the screws carefully) Insert the pre-filter Important: Treat the hepafilter with care because otherwise damages can suspend the effectivity of the filtration.
