Version 3 Page 3
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.

Instruction Manual

Version 3 Page 4
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/m
3
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.

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.

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.

5.Technical description
5.1.Unit description
Negative pressure unit as a container system for filtering asbestos-contaminated room air
via a 3-stage filter unit.
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.

7.2.5. Day / Night setting
By selecting time ranges, it is possible to set on which days and at what time the set value
in automatic mode for the minimum negative pressure in night mode is activated.
7.2.6. Standby mode
A negative pressure unit with SRE connect can be operated as a standby device
(replacement device). If this function is activated, the device switches itself automatically
on if a predefined negative pressure falls below the minimal negative pressure (for
example, if the actual negative pressure unit fails).
The standby mode is switched on in the menu by pressing the button "stand-by".
In the field “Standby waiting time”, a delay of 0-600 seconds can be entered for power
up.
