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
Dealing with the device technology is only permitted for trained competent personnel.
Exact knowledge of the manual is a necessary requirement for the staff when handling the
device.
The operating instructions should always be kept in the immediate vicinity, accessible to
all persons.
deconta must oblige you, as operator of the device, to follow the operating instructions
and to use the device technology only as intended and not in an inappropriate manner! In
case of non-compliance, deconta assumes no liability.
To ensure safety during operation of the device, please strictly observe the following:
• Do not use in potentially explosive atmospheres.
• Maintenance, including removal and replacement of the filters, should only be
carried out authorized personnel wearing appropriate protective clothing.
• For all repair and maintenance work, the unit must be completely disconnected from the
power supply.
• The safety and protective equipment must be in perfect working order.
• Safety instructions affixed to the device are to be left in readable condition and to be
followed.
• 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 operator must carry out the inspection of the exhaust air at initial acceptance as well
as at least a 3-year interval.
In addition to the instruction manual, general, legal and other binding regulations on
accident prevention and environmental protection must be observed.

Instruction Manual
Negative Pressure Unit green dec
Version 1 Page 5
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.
ATTENTION! The device was only tested with original deconta HEPA filters H13 and
original deconta HEPA filters H14. To ensure machine safety, only original deconta
filters should be used. The machine safety cannot be guaranteed if this is not
observed. This may result in the risk of hazardous substances being released into
the environment due to a filter overload (leakage, filter crack, ...) in an unintentional
and uncontrolled manner.

Instruction Manual
Negative Pressure Unit green dec
Version 1 Page 16
The control of the Negative Pressure Unit (NPU) is optionally available in the following
versions:
5.2.Control SE
For power regulation, NPU is supplied with a manual speed controller.
5.3.Control SRE +
For power regulation, the NPU is supplied with a PLC control via a touch display in order
to measure and regulate the negative pressure or the volume flow.
The negative pressure is measured between the contaminated area and a reference point
(adjoining rooms) to be defined and is kept at the set point by continuous speed control of
the electric fan.
The volumetric flow is measured in the unit and is kept at the set point by continuous speed
control of the electric fan. Manual control is also possible.
The fan power is set using the "+" and "-" keys. In "manual" operation the machine does
not regulate!
The need to replace the HEPA filter is indicated on the NPU display.
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.

Negative Pressure Unit green dec
Version 1 Page 17
5.4.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 black area and a reference point to be
defined (adjacent rooms) and kept at the setpoint value by continuous speed control of
the electric fan.
The volume flow is measured in the device and kept at the setpoint 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 a visual
and audible alarm if a value of 100 particles per liter is permanently exceeded.
A necessary filter change is shown on the display.

6.Assembly instruction
The Negative Pressure Unit is shipped ready-to-use from the factory and is intended for
immediate commissioning.
In case of visible damage, do not operate the unit.
Please contact deconta GmbH immediately.
Please note:
In principle, the negative pressure unit can also be operated directly in the
contaminated area (overpressure technology prevents the penetration of
contaminated ambient air into the housing).
Since the devices are contaminated from the outside and therefore have to be
cleaned after completion of the rehabilitation, a use in the contaminated area should
absolutely be avoided.
Integrate the device to the partition wall clean/ contaminated area
Insert approx. 100 mm into the contaminated area
Seal the device with the partition wall
Route the exhaust hose into the open air
Ensure adequate supply air in the contaminated area

7.Initial operation
7.1.Control SE
For power regulation, the negative pressure unit is supplied with a manual speed controller.
Connect the power supply
Operate the controller
7.1.1. Room pressurisation
Set the required negative pressure at the air intake or at the manual speed controller
negative pressure too high: open air supply or decrease speed controller
negative pressure too low: close air supply or increase speed controller

7.2.Control SRE +
Set the measuring point in the contaminated area and connect it to the negative
pressure connection with the PE hose 8 x 1
Determine the measuring point in the clean area (adjoining rooms) and connect to
the atmosphere connection with PE hose 8 x 1
Establish power connection, the following is displayed for approx. 30 seconds
After the initialization, the device is ready for operation. The last saved settings are
automatically set.
