CONTROL ADJUSTMENTS:
CRITICAL: For closer longevity, BACKCHECK
must be adjusted to significantly slow opening
of door before arm bottoms on stop.
Closing time of 3-7 seconds is typical.
More time may be needed for ADA/BF access.
Clockwise (CW) = SLOWER.
Counter-clockwise (CCW) = FASTER.
DO NOT REMOVE VALVES
1. Use hex key provided.
2. Adjust SWEEP (closing max.°- 10°).
3. Adjust LATCH (closing 10°- 0°).
4. Adjust BACKCHECK resistance (opening 70°- max.°).
DO NOT COMPLETELY CLOSE VALVE
5. Adjust (optional) DELAYED ACTION (closing max.°- 70°);
Provides additional hesitation for access (ADA/BF) through
door.
