Aspiration borings
– Bore an aspiration boring with a 10mm drill at a right angle to the pipe.
Deburr the boring carefully and remove chips.
Clean the boring area (across the entire span of the pipe) of grease and dust, e.g. with
Tangit cleaning agent.
– Select the size of the aspiration reducing film sheet according to the specifications.
Glue the aspiration reducing film sheet to the opening.
– Glue the marking tape over the aspiration reducing film sheet, in order to prevent the film
sheet from becoming detached.
Notice!
The holes of the aspiration reducing film sheet and the marking tape must be exactly over the
aspiration boring so that the opening diameter of the aspiration reducing film sheet is not
changed.
To keep the adhesive surfaces of the film sheets free of dust and grease, avoid touching
them.
