The copyright of this instruction manual remains with deconta. This manual is intended for assembly, operation and maintenance personnel. It contains instructions and drafts of technical nature which may neither be distributed nor used in any unauthorised way for competitive purposes or passed on to others.

1. Basic safety advice The operation of the negative pressure unit (NPU) must only be carried out by trained competent personnel. The information and instructions contained within this publication are of paramount importance to the user. The manual is always to be kept in the immediate proximity, accessible to all personnel. deconta insists as the NPU user you follow the information and instruction contained within the handbook and only use it in accordance with the regulations and never use this Negative Pressure Unit in an inappropriate way. In case of non-observance, deconta assumes no liability. To ensure safe operation of the NPU, the following must be strictly observed:

Do not use in potentially explosive atmospheres. Maintenance work, including removal and replacement of the filters, may only be

carried out by authorized persons wearing suitable protective clothing. The device must be completely disconnected from the power supply during all

repairs and maintenance work. The safety and protective systems must be maintained and functioning correctly. Safety instructions affixed to the unit must be maintained in a legible condition and

must be adhered to. General, legal and other binding regulations and procedures for accident prevention

and handling of hazardous substances must be observed. To ensure safety, modifications to the device are not permitted. To avoid damage, never operate the unit without built-in filters. ATTENTION! The negative pressure units are not suitable for use in condensing, corrosive, flammable and explosive atmospheres. We explicitly refer to the additional regional and national safety measures and regulations when operating the device technology. The filter must be checked by an oil thread test (DOP / DEHS) upon initial operation and after each HEPA filter change by the operator. Devices with SRE connect control should be checked and calibrated once a year by the deconta service. In addition to the instruction manual, general, legal and other binding regulations on accident prevention and environmental protection must be observed.


Version 3

1.1. Intended use The negative pressure unit is designed for filtering non-condensing, asbestos-contaminated room air, in the temperature range up to +45 ° C, with exhaust air discharged to atmosphere. In the case of asbestos removal work within contaminated areas, it is expected that airborne asbestos fibres will escape the contaminated area and pose a risk to human health and environment. For these reasons, contaminated areas are separated from the asbestos-free areas and kept under dynamic negative pressure by means of negative pressure units. An integrated filter system reduces the airborne asbestos fiber concentration to a figure of max. 1000F/m3 in the exhaust air. The exhaust air is expelled to the open air. The device is not suitable for filtering flammable gases or dusts. The user must comply with the specified operating parameters of this manual. The device may only be used according to its intended use. Any further use beyond this is not intended. The user is liable for any damages or injuries of any kind whatsoever.


Version 3

1.2. Dangers

DANGER Electric shock due to faulty mains cable. Touching a defective mains cable may result in death or serious injury. Do not damage the mains cable (e.g. by vehicle overrun, tearing, squeezing). Regularly check the mains cable for damage. Have defective mains cable replaced before use by the deconta service or a

qualified electrician

CAUTION Damage due to unsuitable mains voltage. The device can be damaged if it is connected to an unsuitable mains voltage. Check whether the voltage indicated on the rating plate matches the local mains

voltage.

WARNING Hazardous materials. The following materials must not be filtered: Hot materials (glowing cigarettes, hot ash, etc.) Combustible, explosive, aggressive materials and dusts

WARNING Contaminated filters. Filter changes may only be carried out by authorised persons who carry suitable

protective clothing. Dispose of the filter according to the legal requirements.


Version 3

2. Transport and storage 2.1. Transport A crane / forklift with a minimum lifting capacity of 2.2 tons is required for unloading. The unloading point should be firm and level. Transport damages must be documented immediately upon delivery by the supplier. Please also note any damage on the consignment note. 2.2. Storage To avoid any damages, the device should only be stored in clean dry inaccessible rooms intended for unauthorised persons only. Attach the transport lids on the suction side and, if used filters are installed, also cover them.

3. Delivery contents Included in the delivery contents of a negative pressure unit, independent of whether a device has been purchased or rented, unless other agreements have been made: Negative Pressure Unit Instruction manual Transport lid (3 parts) 25 m measuring hose Return after the end of the rental period For the protection of our customers and in the sense of dangerous goods transport regulations, we must insist on the following conditions of return: As listed above Thoroughly cleaned (ready for use) Free from any adhesive residues Without residual fiber bonding agent Without filters Without damages

4. Technical data All data on air performance and volume flows are taking into account a measuring tolerance of ± 15% based on the measuring range end value, determined in a multi-point measuring method with a calibrated vane anemometer. Please note! When using an FI protective device, only all-current sensitive FI protective devices (type B or B +) are permitted. When the power supply of the device is switched on, impulse-shaped charging currents of the capacitors in the integrated EMC filter can trigger the FI protective devices with instantaneous tripping. We recommend residual current circuit breakers with delayed tripping (super resistant). 4.1.

effective air output 70,000 m³ / h three filter stages consisting of a HEPA filter, bag filter and pre-filter energy-efficient and performance-optimised fan with high-capacity HEPA filter acc. to EN 1822 class H13 or H14 automatic or manual negative pressure control / volume flow control automatic soft start, even after power failure all operating control and functional elements are shock-protected automatically opening / closing exhaust flaps

5.2. Control SRE connect IoT (Internet of Things) => Devices with SRE connect control can be remotely controlled and monitored with any internet-enabled computer, mobile phone or tablet. For power regulation, the negative pressure unit is supplied with a control via a touch display to measure and regulate the negative pressure and / or the volume flow. The negative pressure is measured between the containment area and a reference point to be defined (adjacent rooms) and kept at the set point value by continuous speed control of the electric fan. The volume flow is measured in the device and kept at the set point value by continuous speed control of the electric fan. A manual control is also possible. A filter sensor monitors the particle concentration in the exhaust air and triggers an optical and acoustic alarm if a value of 100 particles per liter is permanently exceeded. A necessary filter change is shown on the display.

Version 3

8. Maintenance Maintenance work, including changing/removing filters, may only be carried out by authorised persons wearing suitable protective clothing. The appliance must be completely disconnected from the power supply during all repairs and maintenance work. We expressly refer to possible additional regional and national regulations in the maintenance of the appliance technology. The air-conditioning systems (dust extraction unit, industrial vacuum cleaners and devices used for venting or negative pressurisation) must be serviced as required, at least once a year, and checked by a qualified technician. The test result shall be presented on request. 8.1. Information on filter change The frequency of the filter change depends on the degree of contamination of the filters. As the filter occupancy is increased (contamination of the filters), the air performance decreases. For filter monitoring, the filter pressure is shown in the display of the control system. If the display reaches the red area, please replace pre or bag filter first. If the display value drops by 100 Pascal or more, the unit can be operated again. If the value drops by less than 100 pascals, the HEPA filter must be replaced.

Important: Only use approved filters!
