NOTE
Devices are handed and must be the same hand as door.

Install Body and Backplate Assembly

1. Use the dimensions shown on the 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.

2. 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 a conduit bracket attached to the backplate. (Figure 2)

3. Attach backplate/closer assembly to frame. Position the backplate end with the terminal strip AWAY from hinge of frame.(Figure 1)

4. Make electrical connections as described in the Typical Wiring section.

5. 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.

Install Arm and Track

1. With the appropriate size wrench, rotate closer top spindle approximately 45 degrees.(Figure 3)
   NOTE: Closing both valves for door speed and latching speed makes this procedure much easier.

2. Position closer arm on bottom spindle approximately parallel to the door and arm length AWAY from hinge.

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.

7. With arm engaged in slide groove, slide track into position so that the prepared holes on door align with track holes.

8. Replace end cap and secure track to door.

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.

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 counterclockwise to speed up door movement. Turn the backcheck valve clockwise to increase the intensity of the backcheck action or counterclockwise to decrease checking (as desired).
CAUTION: Set the 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 doorstop. Always use a door stop to stop the door.

Install Cover (Figure 6)

1. Assemble three (3) short cover screws (#8-32 x 5/16″) into bottom of closer body cover mounting bracket approximately one (1) turn.
2. Slide cover onto the backplate and closer assembly. Secure with three (3) cover screws.

CAUTION
Avoid interference with electronics and wires during the installation of cover.

2. Refer to data sticker for proper input voltage and current specifications.
   WARNING: Input power supply must match circuit board voltage rating, either 24VAC/DC or 120VAC. (Refer to data sticker)

3. Energize power supply.

4. Open door to hold open point. Door should hold open.

5. Depress on/off switch. Door should close and latch.

6. Adjustment of spring power may be necessary to ensure proper latching. See the Final Adjustment and Regulating Procedures section.

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.

Adjustment Instructions IMPORTANT

1. CAUTION : Disconnect all input power beginning installation to prevent electrical shock and equipment damage.
2. The 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.
