For full details see the Installation and Maintenance Instructions
(IM-S48-06) supplied with the product.
Installation note:
Preferably fitted in a horizontal pipe but can be fitted in vertically
downwards pipe.
One side of the disc (3) is plain with a single scribe towards the
outer edge, whereas the other side of the disc has a machined
circular groove.
The Airodyn is supplied with the circular grooved side of the disc
towards the seating face and is suitable for clean operating
conditions with the exception of the 'HD' version which has been
designed for particularly contaminated air system having the
scribed disc facing the seat.
If the operation conditions are dirty, probably with heavy oil
contamination, unscrew the cap, using preferably a ring spanner
and turn over the disc so that the plain side with a bleed scribe is
towards the seating face. Replace cap - no gasket is required but
a suitable high temperature anti-sieze grease should be applied to
the threads.
Tighten the cap to the recommended torque.
Do not use a wrench of the Stillson type
which may distort the cap. In extremely dirty
conditions it may be necessary to deepen
the bleed scribe or to make additional
scribes up to a maximum of 3 thus.
The scribe should be over the area covered by and extending beyond
the outer seat face.
The product is recyclable. No ecological hazard is anticipated with
disposal of this product providing due care is taken.
Example: 1 off Spirax Sarco 1⁄2" screwed BSP Airodyn compressed
