– Clean the flexible connector with soapy wa-

paper.
– In the context of a fan check, the connecting
pieces must be visually inspected.
Check for:
– External damage to the bellows or flange
such as hairline cracks, abrasion points,
holes, embrittlement or extreme kinks.
– inadmissible movements, displacement and
installation length.
– Corrosion and wear to the entire component.
– Tight fit of the screw connection

ing functioning is jeopardised
– In case of welding and cutting work, cover
the fabric bellows and protect against heat.
The anode and cathode of the E-welding con-
nection must always be on the same section
