⇒ Place the suction tube onto the suction port (6A / 6B)�
Observe the allocation of the device sockets (A, B) – suction channel (A, B)�
⇒ Connect the suction tube to the correct suction point�
If the diameter is not suitable, use an adapter (see accessories), to avoid loss of suction.
Avoid steep sloping and "sagging" of the tubes.
4.6 Connecting the Electrical Devices
⇒ Connect the electrical equipment to the device sockets (8A / 8B)
on the back�
Observe the allocation of the device sockets (A, B) – suction
channel (A, B)�
When connecting the electrical equipment to the suction unit,
ensure that the sum of the electrical power from the connect-
ed electrical appliances does not exceed the maximum per-
missible total power (see chapter 8 "Tech. Data").
4.7 External Exhaust Air Duct
The exhaust air can be transported out of the laboratory via an external exhaust air duct (see accesso-
ries)�
The installation instructions are included in the external exhaust air duct�
When using suction devices in conjunction with an external exhaust air duct, a large amount of
air is extracted from the room per hour.
This can lead to a negative pressure, whereby, when using air-dependent fireplaces with gas,
liquid or solid fuels, poisonous gases (e.g. carbon monoxide) will be sucked into the (working)
space.
Depending on the structural situation, it is therefore essential to ensure there is an addition-
al air supply or negative pressure monitoring which is checked by the appropriate institutions
(e.g. chimney sweep or heating engineer).
5 Operation
Low-dust disposal of the extracted material is only possible if the waste bag is used�
⇒ Before beginning to work, check that a waste bag has been inserted in the dust drawer�
Waste bags and the starter kit waste bag are available as accessories.
5.1 Switching On
The suction unit is switched on and off via the on / off switch (3)�
After activation:
♦ The suction unit performs an automatic filter cleaning sequence (for approx.
8 seconds, loud vibrating noise) (see chapter 5�3)�
Then the unit is in standby mode�
From the standby mode the unit can be changed to:
• operation, with one or both suction channels (see chapter 5�2);
• programming (see chapter 5�4);
• standby mode (see chapter 5�1�1)�
