4. Setting Up
4.1 Unpacking
EN
⇒ Remove the device and all the accessories from the delivery package.
You will find more accessories in the dust drawer. (To open the dust drawer, see section 6.1).
⇒ Check the delivery for completeness (refer to the "3.3 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).
Up to four suction points can be connected to the extraction unit.
Position the extraction device so that:
• The exhaust air duct at the back of the unit is not hindered.
• The distance to the suction points is approximately even (see section 4.5).
• The front of the device is easily accessible for removal of dust drawer.
4.2.1 Integration in existing Workbench
If the device is to be built into the existing furnishings, it is important to ensure there is a supply
of external cooling air and that the exhaust air is transported out via the external ventilation duct!
For this, please use the cooling air tube and the external ventilation duct available as an accesso-
ry (see accessories).
⇒ Insert the cool air tube into the cool air connection (19, Fig.1).
⇒ Position the cool air tube so that:
- Cool air is sucked in and not the warmed air exhaust air from the extraction unit.
- No dirt is sucked in (e.g. do not place on the floor).
⇒ Install the external ventilation duct as described in the instructions.
In addition, a ventilation opening is also required. The air ventilation passageway must be at least 80 cm²
in size.
The height of the unit can be altered via the adjustable feet at the base of the unit (see accessories).
The installation details are supplied with the unit feet.
4.2.2 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 significant
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 environmental
air pressure is maintained, this should then be monitored by an authorized specialist (e.g. a certi-
fied Gas Service Engineer).
4.3 Electrical Connection
Before connecting the device, ensure that the voltage infor-
mation on the identification plate corresponds with your local
power supply.
Arrange the conducting parts (plug sockets, plugs and cou-
plings) and install the extension cord so that the protection
class is retained.
⇒ Switch the device OFF at the On / Off switch (3, Fig.1).
⇒ Connect the power cable (18) to the power supply (13) (for units
produced until March 2018).
⇒ Insert the mains cable into the plug socket.
