B-B Door Closer Installation Instructions

Determine the Door Direction

This section illustrates how to determine the door direction (Left-open Door vs. Right-open Door) for installation.

Left-open Door: Pull side, inside view.

Right-open Door: Pull side, inside view.

Visual representation shows 'Pull' and 'Push' directions relative to the door's interior.

Adjustment After Installation

Instructions for adjusting closing speed and latching speed:

• Closing Speed Adjustment: Turn the regulating valve clockwise to slow down, counter-clockwise to speed up.
• Latching Speed Adjustment: A second regulating valve controls latching speed.
• Closing Power Adjustment: This involves adjusting the mounting base and hinges.

Visuals depict adjustment screws and their effect on closing power.

Standard Installation: Verticle Installation on Door of Pull Side

This covers the installation for a right-open door, with similar dimensions applying to a left-hand door measured from the hinge edge.

Components: Arm screw & washer, Mounting base, Speed regulating valve, Hinge center, Door frame, Door, Cover Cap.

Installation Instructions:

1. Select the degree of opening and use the provided dimensions to mark holes on the door and door frame. Install the door closer.
2. Place the main arm on the shaft of the door closer as illustrated.
3. Ensure the regulating valve faces the hinge side when installing the door closer body.
4. Attach the arm shoe of the forearm to the door frame.
5. Adjust the forearm length so that when attached to the main arm, it forms a right angle (90°) with the door. Secure the elbow with a locknut and connect the forearm and main arm with a screw and washer.
6. Place the cover cap over the shaft at the bottom of the closer and turn slightly to secure.
7. Do not spin the regulating valve completely out of the mount, as this can cause oil leakage and unadjustment.

NOTICE: Before installing, do not spin the shaft beyond 180° for hold-open function door closers, as this can damage the closer.

Position and Installation of Arm

Diagrams show the correct positioning of the main arm on the shaft for both right-open and left-open doors.

Right-open door: Shows forearm, lock nut, and the position of the main arm installing on the shaft.

Left-open door: Shows forearm, lock nut, and the position of the main arm installing on the shaft.

Closing Speed Control

Notice: Do not spin the regulating valve out of the closer mount.

Standard closing circle: Illustrates the 10° closing angle.

Closing: Regulating closing door time from 90° to close should be 4-6 seconds. For elders and children, the closing time can be longer.
