DOOR CLOSER ADJUSTMENTS

Arm Attachment to Track

Insert arm stud into slide block in track.

Secure by pushing in on the retainer clip that extends from the slide block, until it is flush with the slide block, see illustration on page 2 of these instructions.

Hold Open Angle:

Place door in the Hold Open position. Remove 9/64" hex drive socket head screw from arm. Open door to desired angle and install hex-drive socket head screw into hole in adjusting rod that is aligned with the hole in the adjusting tube.

Closing Power

Closing Power can be increased by 50%.

To increase power, see Figure 1, rotate "Spring Adjustment Nut clockwise using a 11/16" wrench or socket. 15 full turns (360°) will provide maximum available power.

Closing Cycle (hydraulic control)

See figure 2A.

Valve "L" controls door speed in Latch range.

Valve "S" controls door speed in Sweep range.

Use 1/8" hex-key furnished and adjust as shown in figure 3

Opening Cycle (hydraulic control)

See figure 2B.

Valve "B" cushions (slows) door opening in the backcheck range.

Note: Never close this valve completely or damage to closer may occur.

Valve "P" allows "backcheck" to begin later in the opening cycle.

Use 1/8" hex-key furnished and adjust as shown in figure 4

Installation of Cover:

Fasten cover to closer with two screws provided:

• Molded Cover fastened at the top of closer.
• Metal Cover fastened at each end of closer.

Using four screws provided, fasten metal hook-up box cover.

Hold Open Power Adjustment:

If more hold open power is required, the power may be increased by turning the adjustment screw in the end of the track nearest the hinges. Use 9/64" hex wrench provided and rotate adjustment screw clockwise to increase holding power.
