• This template information based upon use of 5" (127mm) maximum width butt hinges. A separate template is required for other conditions.
• Maximum frame reveal is 6-7/8" (175mm) for this application.
• Conduit hole is Class 2 low voltage wiring ONLY.
• !Due to the risk of the Power Cord becoming entrapped in moving parts of the operator, door, or system, the Power Cord must be kept clear of all moving parts.

Note: Door must be visible by person operating activation switch(es)

1A. Installation Sequence

• Step 1: Determine hand of door from illustration on upper right of this page.
• Step 2: Using template above locate and prepare holes in the frame & door:

Frame

• A. Prepare six (6) holes for 1/4-20 machine screws or No. 14 x 2-3/4" (70mm) wood screws.Blind rivet nuts (by others) are suggested for unreinforced hollow metal frames or for aluminum frames.
• B. Concealed Class 2 Low Voltage Only: One (1) 7/8" (22mm) diameter hole for conduit, for switch/sensor wires only. NOTE: On new construction this hole will generally be drilled by the frame supplier at their shop or at the time the frame is installed in the wall.

Door

C. Prepare three (3) holes for 3/8" diameter sex nuts.Standard units

are supplied with sex nuts and screws for 1-3/4" (44mm) thick door. Sex nuts and screws for other door thicknesses are available to order.

Step 3: Remove cover from the unit and set cover & cover screws aside.

Step 4: Mount unit to door frame. Select A or B below.

• A. Concealed Class 2 Low Voltage Only: Connect conduit to frame side of backplate. Fasten unit to door frame (seven screws).
• B. Surface Class 2 Low Voltage Only: Fasten unit to door frame (seven screws). Mount conduit bracket (found in screw pack) to unit's backplate with two screws provided. Connect wiring conduit to bracket.
• Step 5: Mount track assembly to door using 3 1/4-20 screws & sex nuts with buffer assembly toward hinge. Open part of track to face top of door.

1A. Installation Sequence Continued

Step 6: Insert slide arm rod into slide arm tube setting the distance between the pinion square and the slide stud at 13-1/2" (343). Install 9/64" hex drive socket head screw from screw pack. (See illustration below)

Note: Center threaded hole of slider arm should align with seventh hole of the slider tube

Step 7: Using an adjustable wrench, rotate pinion 45° toward hinge, as shown below. With the arm assembly parallel to the door, secure arm to pinion when square of the pinion aligns with the square in the arm. Secure with countersunk washer and 1/4-20 Flat Head Screw (with thread lock) provided. Tighten screw with 7/16" wrench or socket.

Step 8: Insert arm stud into slide block in track assembly. Secure by pushing in on the retainer clip that extends from the slide block in the track, until it is flush with the slide block (see illustration below).

Step 9: Adjust closing power of unit (See Fig. 1) - Using a 1/8" allen wrench, turn the power adjustment shaft clockwise to increase door closing power. Door control is shipped set at midpoint of power setting. Maximum closing power can be achieved with 8 (360°) clockwise turns of the power adjustment screw.

Step 10: Adjust Hydraulic valves using a 1/8" hex wrench to obtain proper door closing speeds. See following illustrations. Refer to Table 1 below for recommended minimum opening / closing times per ANSI/BHMA A156.19.

Closing Cycle – Make adjustments, as necessary, to the Sweep Speed "S" valve and Latch Speed "L" valve. See Fig. 2 below for location of valves. Turn valves clockwise to reduce speed, counter clockwise to increase speed.

Opening Cycle – Adjust Backcheck, "B" valve, as necessary, for hydraulic resistance to door opening in the backcheck range. See illustration in Fig. 2 for location of valve.

NOTE: Too much Backcheck, "B" valve, can affect the operation of the units pump, preventing units from fully opening the door. This valve may require fine tuning after all other adjustments have been made.

Note: A.D.A. requires that from an open position of 70°, the door will take at least 3 seconds to move to a point 3" (75mm) from the latched position, measured at the leading edge of the door.

Step 11: Make wiring connections using Wiring Instructions on Page 7 and 8.

Rotate main arm in direction away from the hinge edge until the adjusting rod and arm slide are perpendicular (at a 90° angle) to the door frame. Tighten the 1/4-20 hex head screw on the adjusting rod to secure arm in this new position.

Step 9: Adjust closing power of unit (See Fig. 5) - Using a 1/8" allen wrench, turn the power adjustment shaft clockwise to increase door closing power. Door control is shipped set at midpoint of power setting. Maximum closing power can be achieved with 8 (360°) clockwise turns of the power adjustment screw.

Step 10: Adjust Hydraulic valves using a 1/8" hex wrench to obtain proper door closing speeds. See following illustrations. Refer to Table 1 on page 5 for recommended minimum opening / closing times per ANSI/BHMA A156.19.

Closing Cycle - Make adjustments, as necessary, to the Sweep Speed "S" valve and Latch Speed "L" valve. See Fig. 6 below for location of valves. Turn valves clockwise to reduce speed, counter clockwise to increase speed.

Opening Cycle - Adjust Backcheck, "B" valve, as necessary, for hydraulic resistance to door opening in the backcheck range. See illustration at bottom of this page for location of valve.

NOTE: Too much Backcheck, "B" valve, can affect the operation of the units pump, preventing units from fully opening the door. This valve may require fine tuning after all other adjustments have been made.

Note: A.D.A. requires that from an open position of 70°, the door will take at least 3 seconds to move to a point 3" (75mm) from the latched position, measured at the leading edge of the door.

Step 11: Make wiring connections using Wiring Instructions below and on Page 8.

3. Electrical Connections and Final Setup

• Step 1: Confirm all mechanical adjustments have been made.
• Step 2: Plug Power Supply Cord C13 end into Power Inlet of unit. Insert three (3) prong plug of opposite end of Power Supply Cord into electrical outlet.

Step 3: Turn power to unit on at the Unit Power Switch and turn the Breaker Switch to "RESET". Breaker

Step 4: Using a short jumper cable, jump terminals 1 and 2, see Fig. 2 below, to activate unit. When door reaches 20°, switch Breaker Switch to "OFF" position cutting power to the unit. Allow door to fully close (door may be manually pulled closed).

3. Electrical Connections and Final Setup Continued

Step 5: Adjust Closing Position Magnet (See Fig. 3) - With door in the closed position, use finger to slide Closed Position Magnet so it aligns directly with the Reed Switch.

Step 6: Adjust Open Position Magnet - Use fingers to slide Open Position Magnet 180° from Open Position Magnet.

• Step 7: Flip Breaker Switch to "RESET" to turn power on. Jump terminals 1 and 2 (as shown in Fig. 2) to activate door. Note open position of the door. Allow door to close.
• Step 8: Use finger to readjust the Open Position Magnet to desired door open position.
• Step 9: Repeat Step 7 to verify door open position.
• Step 10: Make all connections necessary for any accessories to the 4-position Accessory Terminal (see Pages 9 - 118).
• Step 11: Make necessary adjustments to inverter (see Page 9). Replace cover and cover screws.
