Installation Instructions

1 To Change Hands

• 1. Remove four (4) screws and Vertical Lifter Assembly.
• 2. Rotate device to opposite orientation (180° degrees).
• 3. Insert Lifter Assembly and reinstall screws.

NOTE: Lifter must fit under lift block as shown. (Figure 1)

2 Maintenance

• 1. Periodically remove covers and coat mechanisms with an appropriate lubricant. This is particularly required in corrosive environments for proper product function.
• 2. Check mounting fasteners periodically. Re-tighten if found loose. Apply screw locking compound or change part fasteners if screws continue to back out.
• 3. Periodic checks (and adjustments) or rods may be required, to compensate for changes in the opening (e.g.: door sagging).

Installation Instructions

14 Complete Installation (4800M & ED4800MA Shown)

A. Rehang door plumb and true to opening. Set strike roller between tripping lever and bolt. DO NOT PRELOAD BOLT. Shim strike as needed. (Figure 28)

NOTE: Rods should move freely inside door. Bolts extend automatically and should deadlock when door closes and top strike hits tripping lever. Top bolt should retract flat. Bottom bolt should travel 1/2" (13) and engage 3/8" (9.5) into strike in down position without dragging on floor surface in up position.

Test device action by touchbar, by trim, and by dogging. Adjust as needed.

• B. Rod Adjustment for Proper Bolt Throw
  • 1. Use 3/32" (2.4) hex wrench to loosen set screws B1 and B2. (Figure 28)
  • 2. Adjust top rod first with adjusting screw C1. (Figure 28) With device in dogged position (panic devices) or touchbar fully depressed (fire devices) adjust top rod so that top latchbolt is flush and hold back feature is engaged. Lengthen top rod an additional 1/2 turn for proper latchbolt positioning.

NOTE: If adjusting screws bottom out before proper device operation, door and device must be removed so larger adjustments may be made by threading rod in or out, or by moving cotter pin to different hole in rod. (Section 8, page 6)

14 Complete Installation Continued (4800M & ED4800MA Shown)

• 3. Adjust bottom rod with adjusting screw C2. (Figure 29) With top latch retracted in hold back position, and touchbar dogged or fully depressed, adjust bottom rod so that deadbolt clears strike by 1/16" (1.6). The bottom rod should be in position in active case with square head of connector hanging in the Guide. (See note in Step 2).
• 4. Check device operation by opening and closing the door. An additional minor adjustment may be required for full retraction and correct strike engagement.

NOTE: To avoid thread damage and provide positive locking, be sure set screws engage flats on adjusting screws.

• C. After acceptable device function, install third screw in top strike to lock strike in position with 10-24 x 3/4" PFHMS.
• D. Install device cover and end cap with (2) 8-32 PFHMS each.
