1.3 Conventional use
n Fume cupboards: The fume cupboards are determined to extract and lead off corrosive gas arising during
chemical processes in a conventional laboratory environment. Each fume cupboard may only be used
according to its determination (approval) and its choice of material that is either chemically, thermally or
mechanically.
n
Extract air function display: The function display is exclusively determined to control extract air flows in
laboratory fume cupboards according to DIN EN 14175. Utilization in explosive areas may only be allowed
for special executions and with an exact clarification of the operational conditions.
n Fume cupboard sash control: The fume cupboard sash control is exclusively determined for an automatic
closing of fume cupboards not in use, to protect the staff (splash protection) and to avoid pollutant emission
when people drop across. The automatic fume cupboard sash may not be used in explosive areas.

Every type of fume cupboard has a certain air technical operating range. Within this range the extract air volume
may fluctuate. Relevant specifications are shown on the type labels of the fume cupboards and in the technical
documents.
3.5 Fume Cupboard Function Display
According to the DIN EN 14175 each fume cupboard type is equipped with an extract air function display. This
function display is installed at the side of the fume cupboard. Each fume cupboard shows a certain pressure
drop that depends on the extracted air volume. Measurements of a fume cupboard´s pressure drop is usually
made through a differential pressure measurement between the laboratory and the extract air spigot of the laboratory. In this case the laboratory fume cupboard represents the streamed obstacle. The measuring outcome
results are indicated by a LED.

Please pay attention to the safety instructions according to chapter 1.8
Especially pay attention to the following points:
n Keep front slide closed during tests.
n If possible, set up tests in the rear working area and on stands.
n Check surfaces for resistance.
n Check fume cupboard for possible deposits and clean it, if necessary
n Intake openings shall be free.
n Connection cables and hoses shall be safely laid/installed
4.2 Sash
Always keep the sash closed during tests and if not in operation. The sash should only be opened during the
test set up. For short-term access always use the cross slides. The fume cupboard may be manually operated
at any time, irrespective of an optional sash control. The sash may be horizontally opened and closed by the
loop handle. When opening the sash it should be opened up to the stopper that stops the sash at an opening
height of 500 mm (normal operation). Beyond, the sash may only be opened by turning the loop handle. The
sash should be opened beyond 500 mm only during the test set-up. As soon as the sash is pulled down it is
automatically locked below the 500 mm marking.

Components
The electronic control of the fume cupboard is automatically closing, in case the fume cupboard is not in operation. A passive infrared detector (PIR) continuously controls the working area in front of the laboratory fume
cupboard. If no operating staff is directly in front of the lab fume cupboard, the automatic locking process of the
sash is started. The pollutant emission of a fume cupboard is lowest if the sash is closed. In connection with a
fume cupboard control it is energy saving and the air volume escaping above the fume cupboard is reduced.

n
Infrared light barrier: Detects objects that might obstruct the automatic locking process. Diffusion of the light barrier ray is less than 1 mm. The sender/receiver light barrier is installed on the left and the
right bottom side of the sash and controls the locking process. Instruments leading through the
laboratory sash (e.g. measuring probes, flasks, etc.) are detected and the automatic locking process is
stopped immediately.
n Control key: incorporated into the control panel of the fume cupboard function display: Foil keys are available for the operation modes UP and DOWN. The keys control the movement (UP, DOWN) or
immediately stops movement of the fume cupboard sash. It is also possible to manually move the sash.
n Control: The control system is processor-controlled. The locking delay is freely adjustable from 10 s.
to 30 min.
n Drive: The drive consists of a motor, an electromagnetic coupling and a distance sensor.
n Loop handle: With this handle the sash may be moved or stopped manually without changing the grip.

User Manual | DELTAGuard | General Instructions
Operation
Irrespective to an automatic sash control, the fume cupboard may be operated manually at any time and without limitations.
n Manual Operation: If the sash is in an inactive position it may be opened and closed with the loop
handle. Drive and sash are decoupled when in inactive state.
n Opening sash through the motor: Briefly actuate key
UP
The sash opens and automatically stops at an opening height of 500 mm. By briefly actuating the key
UP or DOWN any movement is stopped immediately.
DOWN
n Closing sash through the motor: Briefly actuate key
The sash closes and automatically stops in the BOTTOM position. By briefly actuating the key UP or
DOWN any movement is stopped immediately. The light barrier monitors the closing movement for
obstacles.
n Automatic locking device: In case no activity was detected in the fume cupboard within a given time
frame the sash is automatically closed and stops when in BOTTOM position. The light barrier monitors
the closing movement for obstacles. If a person is detected during this locking process, the process will
be stopped immediately (optional).
.
NOTE
The time frame until the closing of the sash may be varied in a range from approx. 10 seconds to 30
minutes. This setting shall be made by experienced and well trained service staff only.
n Detection of obstacles: If the sash is in up or down movement, the direct area below the handle bar
is monitored by means of a light barrier. 02 03
An interruption of the signal by touching the working room or object, projection from the interior cause
an immediate stop of the movement.
Danger!
In case a detected obstacle stopped the closing process, the locking mechanism is deactivated. By
actuating the UP or DOWN key, or by manually sliding the sash for at least 3 cm, the locking mechanism is reactivated (return to normal operation).
note
Other criteria may be programmed for returning to normal operation (2 cm downward movement, or
only a manual sash movement). This setting shall be made by experienced and well trained service
staff only.

detergent with soft cloth only.
Cleaning of Extract Air Ducts:
n Extract air ducts are accessible as soon as the scaffold rods are detached.
n Unscrew 3 x screws in the bottom area of the rear baffle.
n Unscrew hexagon socket screw (5mm) of the scaffold rod holder.
n Detach scaffold rod holder and rear baffle.
n Clean extract air ducts.
n Reinstall rear baffle and scaffold rod holder and tighten hexagon socket screws.

and damages.
DANGER!
n The measuring hose may neither be damaged nor kinked. It shall be tightly fixed to both,
the extract air spigot and the sensor.
n Checking of limiting values. Detach the hose from the function display.
n Checking of back-up battery is checked by switching of the power supply.
Note

n Checking of the functions of the light emitting diodes. Detach the hose from the function display.
n Checking of warning signal. Switch the device off. Press QUIT key
as soon as the
warning signal sounds.
Replacement of means of Illumination:
n To illuminate the fume cupboard interior 2 x 30 Watt fluorescent tubes are being used. In case of a failure
of these tubes they shall be replaced immediately.
n The front panel is held by two bars at the back side. Thanks to the 2 bars, the panel can be swivelled to
the front or may also be unhinged completely.
n Remove the metal housing of the lamp from the ceiling of the fume cupboard. Remove 2 sheet metal
screws from one of the front sides of the housing. Push the housing aside as far as necessary to be able
to remove the glass. Chance the fluorescent tubes. Put the housing back together in reversed order.
