Install Body and Backplate Assembly

1. Use the dimensions shown on the provided template 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 the backplate/closer assembly to the frame. Position the backplate end with the conduit connection away from the hinge of the frame. (Figure 1)
4. Make electrical connections (see page 5 )
5. Make input power connections to the power supply board as directed in the Typical Wiring section.
   NOTE: If electrical connections are to be made at a later date, place the cover on the chassis now to prevent its loss.

Install Arm

Regular Arm

1. Attach foot to door with foot pivot AWAY from hinge edge of door. Move foot pivot to hole nearest hinge for additional closing power for all models. (Figure 3)
2. Assemble main arm to closer with index mark on spindle. Align with axis of arm. Use washer and screw. (Figure 4)
3. Open door and insert rectangular rod into swivel arm. Close door and tighten arm screw securely. (Figure 5)

Deep Reveal Arm (Models 2994, 2995)

1. Assemble main arm to closer with index mark on spindle. Align with axis of arm. Use washer and screw. (Figure 4)
2. Adjust length of rod assembly to position rod at right angle to door. (Figure 6)
3. Attach the foot of the rod assembly to the door.
4. Tighten locknut on rod.

Final Adjustment and Regulating Procedures
Adjust Spring Power According to Chart (Figure 7)

Turn the 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 8)

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 9)

1. Assemble three (3) short cover screws (#8-32 x 5/16″) into the 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 installation of cover.

Typical Wiring

CAUTION

1. Disconnect all power before 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.
4. Maximum wire size is 18AWG.

Stand-Alone Units (Figure 10)

1. Wire stand-alone unit to the appropriate power supply and fire alarm.

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 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 11)
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 12) Cam should be positioned so when door closes, roller on switch will ride up incline of cam operating the switch.
4. Tighten on set screw in cam with hex key and pull door closed.
5. 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 13)
6. 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.
