FINAL ADJUSTMENT AND REGULATING PROCEDURE
Adjust Door speed, and Latching speed valves to achieve the desired closing time.
Recommend 6 seconds minimum from 90° to the closed position.
If Backcheck is required, adjust valve to achieve a slight cushioning effect. Auxiliary stop required.
If closer is equipped with Delayed Action, regulate valve to achieve the desired delay.
ADJUST POWER TO ALLOW DOOR TO CLOSE AND LATCH.
Adjust closing power to the minimum required to reliably close and latch door.
- If door is hard to open, decrease power slightly.
- If door does not latch, increase power as required.
- Use the chart as a starting point.
- Doors adjusted with high closing power to overcome
strong draft conditions may exceed ADA standards.
