Read Before Commissioning - Trotec DA 4 Mode D'emploi

The DA 4 and DA 4 M Discharge Control Unit saves the
measurements on an integrated USB flash drive. Previ-
ous drying processes are thus documented. The DA 4
M Discharge Control Unit additionally sends in intervals
the sensor measurements to a WEB centre and thus
offers online remote monitoring of the drying process.

02. READ BEFORE COMMISSIONING

The DA 4 / DA 4 M Discharge Control Unit is to be
used as a control unit for drying insulation layers in the
suction process of floor screed or flat roofs exclusively.
The unit consists of a casing in which the valves, the
control unit and the connection nozzles are installed,
as well as the humidity sensor with adapter, which is
plugged into the respective holding fixture for trans-
portation purposes. During operation, the sensor is
installed at a four-fold distributor at the compressor by
means of the adapter.
m The humidity sensor must not have direct
contact with water!
m Never place items on the device or step on it.
The Discharge Control Unit can be used with all con-
ventional compressors in suction processes for the
drying of insulation layers. Furthermore, the device is
specifically aligned to the Trotec Multi-Qube modules.
The task of the Discharge Control Unit is to efficiently
distribute the suction flow to the existing core drill ho-
les; it is positioned between the water extractor and
the core drill holes. Water, particulate matter, fine dust
or other small particles are not filtered through the
device. Foreign bodies of this kind do not impair the
function of the device.
m Foreign bodies with a diameter of more than
15mm may lead to a clogging of the valves.
For this reason, the core drill hole is to be
cleaned thoroughly before drying. An indus-
trial vacuum cleaner is suitable for cleaning.
The Discharge Control Unit does not have any defined
inputs and outputs. It is irrelevant from which side the
hoses are connected.
B - 2
m All three inputs and all three outputs must be
Ensure a proper connection of the inputs and outputs.
Insufficient connections with the aluminium nozzle of
the Discharge Control Unit may result in leakages.
This will lead to reduced drying performance. In a
worst case scenario, water leaks from the connection
and causes water damage. Use hoses with smooth
and elastic internal surfaces or spiral hoses with a co
responding special clamp. With the Discharge Con-
trol Unit, you can directly control three core drilling
holes. By means of T/Y pieces or other distributors,
the number of the controllable core drilling holes can
be expanded. Here, ensure that the core drilling holes
which are controlled via one duct are grouped closely
together.
Generally, before using the MultiQube elements,
water in the core drilling holes must be removed via
suction before starting the drying process. This shor-
tens the drying time for rectifying the water damage.
All three ducts of the Discharge Control Unit must
be connected as otherwise correct functioning can-
not be guaranteed and the connected compressor
turbine will be damaged.
The use of a Discharge Control Unit in explosion-risk
rooms and atmospheres is inadmissible.
The Discharge Control Unit may only be operated by
specialist staff and experts who have been instructed
regarding the operation of the devices and are trained
in the area of insulation layer drying technologies.
The operating manual must be followed. Instructed
persons are persons who have been informed and,
if required, trained regarding the tasks transferred to
them and the possible hazards occurring in the event
of inappropriate behaviour.
