The Airodyn is supplied with the side having the annular groove facing the valve seat, suitable for clean operating systems. If the system is relatively dirty, use a suitable wrench to loosen the valve cap, reverse the disc, and position the side with the drain scratch facing the valve seat. Tighten the valve cap without using a gasket, but apply high-temperature grease. Tighten the valve cap to the appropriate torque, avoiding the use of adjustable wrenches to prevent twisting the cap. If used in dirty environments, increase the depth of the scratch or increase the number of scratches (up to 3 scratches). The scratches should be evenly distributed on the disc surface and facing outward. **Handling** This product is recyclable and will not cause ecological problems if handled properly. **Ordering Instructions** Example: 1-½' Spirex Airodyn air compressor drain valve, threaded connection BSP. **Spare Parts** Spare parts are indicated with solid lines in the diagram; dashed parts are not available.
