4. Setting Up
4.1 Unpacking
⇒
Remove the device and all the accessories from the delivery package.
⇒
Check the delivery for completeness (refer to the “Scope of Delivery” section).
4.2 Setup
The extraction unit is a free-standing appliance, intended to be set-up on the floor (e.g. under the work
-
bench).
It is possible to connect up to two suction points.
Position the extraction device so that:
• The exhaust vent (14, Fig. 1) is not blocked.
• The distance to the suction points is approximately even.
• The front of the device is easily accessible for removal of dust drawer.
If the device is to be installed in a cabinet, an opening for the exhaust air with the following dimensions
must be provided, in addition to the openings for the suction hoses:
•
Circular opening:
Min. 120 mm diameters
•
Rectangular opening: Min. 170 x 65 mm
4.2.1 External Exhaust Air Route
An external exhaust air route (see accessories) allows the extracted air to leave the laboratory.
The installation details are supplied with the external exhaust air route.
When the extraction unit is used in conjunction with an external ventilation system, a signifi
-
cant quantity of air is extracted from the room per hour.
This can create negative pressure within the room which, when using an air dependent naked
flame fed by gas, liquid or solid fuel, can cause poisonous gasses (e.g. carbon monoxide) to be
drawn into the working area.
It is therefore essential to ensure that the fresh air supply is sufficient and that the environmen
-
tal air pressure is maintained, this should then be monitored by an authorized specialist (e.g. a
certified Gas Service Engineer).
4.3 Electrical Connection
Before connecting the device, ensure that the voltage information on the identification plate
corresponds with your local power supply.
Arrange the conducting parts (plug sockets, plugs and couplings) and install the extension
cord so that the protection class is retained.
⇒
Switch the device off at the on / off switch (3, Fig. 1).
⇒
Insert the mains cable into the plug socket.
4.4 Compressed Air Connection
The suction hoses are opened and closed via the pneumatic pinch valves (15, Fig. 3).
For this, compressed air is necessary. On the device, the compressed air tube is sealed.
Connection to the compressed air supply:
⇒
Select the appropriate tube connection piece from the connection set (17, Fig. 1) and attach to the
end of the tube.
⇒
Connect to the compressed air.
Observe the minimal / maximum connection pressure, see technical data!
Compressed air should be clean and dry (without condensed water). Wet compressed air can
damage the unit.
