Install Body and Backplate Assembly

1. Use dimensions shown on template provided to prepare holes.

For concealed wire applications:

Locate and drill 1-1/8" diameter hole in the frame face for 3/4" conduit. (This is normally done at the time the frame is being installed.) Connect conduit to backplate before fastening backplate to frame. (Figure 1)

For surface wire units:

Use conduit bracket attached to backplate. (Figure 2)

• 2. Attach backplate/closer assembly to frame. Position backplate end with terminal strip AWAY from hinge of frame. (Figure 1)
• 3. Make electrical connections as described in Typical Wiring section.
• 4. Make input power connections to power supply board as directed in Typical Wiring section.

NOTE: If electrical connections are to be made at a later date, place cover on chassis now to prevent its loss.

• 3. Secure arm with screw and washer.

• 4. Remove end cap from track.
• 5. Position track with open side up.
• 6. Insert roller end of closer arm in sliding groove of track.

3 Final Adjustment and Regulating Procedures

Adjust Spring Power According to Chart (Figure 4)

Turn spring adjustment nut clockwise the required number of turns to match door width as indicated in chart.

NOTE:

• • Where strong drafts exist, increase spring power as needed.
• • 351 Style door closers normally leave the factory with spring adjustment set at eight (8) turns.

Figure 4

Maximum Width of Door Interior Only	Clockwise Turns of Adjusting Nut
2' 8"	8
3' 0"	8
3' 6"	12
4' 0"	16

Max adjustment is approx 20 turns. Do not forcibly extend adjustment beyond limits.

Adjustment Instructions (Figure 5)

Minimum recommended door closing time is 6 seconds for doors opened to 90 degrees.

Using 1/8" hex wrench, turn valve screw clockwise to slow down or counter clockwise to speed up door movement.

Turn backcheck valve clockwise to increase intensity of backcheck action or counter clockwise to decrease checking (as desired).

CAUTION: Set backcheck valve for a slight cushioning effect. It is damaging to the closer if the checking action is too abrupt. Backcheck should never be used as a door stop. Always use a door stop to stop the door.

Optional 80- Prefix Bypass Hold Open Switch for 2960, 2970 & 2990 FIREGUARD®

General Information The 80 prefix switch allows initial hold open point to be adjustable from 20 degrees through full door opening. This adjustment is done using a cam on spindle opposite from where arm mounts. Set Screw (2 Places)

Adjustment Instructions

IMPORTANT

• CAUTION: Disconnect all input power beginning installation to prevent electrical shock and equipment damage.
• 2. Installer must be a trained, experienced service person.
• 3. All wiring must comply with applicable local electrical codes, ordinances and regulations.

INSTALLATION

• 1. Mount closer/holder per instruction sheet provided.
• 2. Locate switch roller and cam and loosen both set screws in cam. (Figure 8)
• 3. Open door to desired holding position and hold open with door stop. Rotate cam until switch roller is on lower section of cam and approximately 1/32" from bottom of incline. (Figure 9) Cam should be positioned so when door closes, roller on switch will ride up incline of cam operating the switch. Tighten on set screw in cam with hex key and pull door closed.
• 4. Pull door open to desired hold open position. When switch roller travels down to bottom of incline, door closer will function as a standard multi-point holder. (Figure 10) Depending on door size and closer fall back, cam may need to be adjusted so that switch roller is positioned further from base of incline. When cam is positioned properly for desired door operation, tighten both set screws firmly.
