Adjusting Screw
Adjust closing power to the minimum force required to reliably close and latch door.
yIf door is hard to open, decrease power slightly.
yIf door does not latch, increase power as required.
yUse chart below as a starting point.
yDoors adjusted with high closing power to overcome strong
draft conditions may exceed ADA standards.

44 - 48 15 -17 turns CW 8 turns & Up CW
* If interior doors do not have to comply with ADA requirements, exterior settings
are recommended. Where strong drafts exist, increase spring power as needed.
NOTES:
‒Adjusting door to close due to high draft conditions may
exceed ADA standards.
‒Consult local ordinances when fire doors are involved.
To Adjust Holder Arm (PSH Arm ONLY)
Adjusting Nut
All PSH arms are shipped in Non-Hold Open from the factory.
To set in Hold Open, turn the adjusting nut approximately
1-1/2 turns clockwise.
yRecommend 6 second minimum from 90° to the closed position.
yClosing and Latching Speeds: Turn valves clockwise to slow down or counterclockwise to speed up door movement.
yBackcheck: To regulate the intensity of backcheck action, turn valve clockwise to increase or counterclockwise to decrease check-
ing. CAUTION: Set valve for slight cushioning effect; Closer can be damaged if the checking action is too abrupt. Never use the
backcheck as a door stop. Always use a door stop to stop the door.
yDelayed Action Feature (Optional on some models): Delayed action provides slow door closing through the delayed action range.
Turn valve clockwise to slow down or counterclockwise to speed up door movement.
