The extraction air unit is used for the technical extraction of air from the inside of cabinets. The extracted air stream
does not get in contact with the electric current leading or metallically blank construction parts. The unit is suitable
to extract cabinets which are defined in the EN 14470-1/2.

HF.EA.8677 / HF.EA.11442 / HF.EA.17447
Install the extraction unit with the extraction air inlet on top of the cabinet. Connect the customer provided ext-
raction air duct appropriate to the extraction air outlet of the unit. The extracted air from in side safety cabinet can
either flow into a suitable ventilation system or must flow in safe place into the free.
ATTENTION: Use plastic duct with cabinet models VBFA/VBFT/VBF type series 196.

1. Bolt the enclosed brackets onto the side of the ventilation module.
2. Place the ventilation module with its inlet opening over the outlet connector of the underbench cabinet, and
align it horizontally.
3. Mark the positions of the holes required for the brackets on the rear wall of the underbench cabinet. Spot-drill
the marked holes with a small wood drill. Then position the ventilation module with the brackets in the appro-
priate positions, and fasten the brackets to the rear wall with the wood screws included.
4. Connect the outlet connectors (Ø 75 mm) on the ventilation module to the customer's exhaust air ducts. Note
that the connection must exhibit a degree of elasticity.
5. Insert the mains plug into a socket that is earthed in accordance with regulations.
3. Put into operation
Put the power supply plug into a correctly grounded power socket.
Activate the rocker switch (Position ON).
