• Step 2. With the door open, turn the key counterclockwise to its stop, and remove it from the lock.

Installation Instructions

INTRODUCTION

Follow these basic precautions:

• The bolt of the Key Lock can withstand an end load up to 1.8 lbs. (8 N). Forces greater than this amount may prevent the lock from working properly.
• The key requires a minimum keyhole diameter of 1 ⁄2 inch (12,7 mm). If a guide tube is used with the lock, the minimum diameter increases to 11⁄16 inch (17,5 mm).
• Installer modifications to the Key Lock are not covered by the manufacturer's warranty.
• Take precautions to prevent metal shavings, safe insulation, paint, weld spatter, or other foreign material from entering the lock.
• Make sure the lock is not installed in a manner that will allow objects to come in contact with the changing button.
• The lock can be mounted right-hand (RH), left-hand (LH), vertical-up (VU), or vertical-down (VD).
• The safe must incorporate a relock device, or have a plate of at least 12-gage steel attached to the back of the lock. Plate dimensions are given in the drawing at right. Attaching screws must be inserted into the blind holes on the lock's back.
• The lock should only be serviced and lubricated by trained service personnel. Improper service or lubrication will damage the lock and void the manufacturer's warranty.

ATTACH PLATE TO LOCK USING (2) 8-32X3⁄ 8" SELF-TAPPING SHEET METAL SCREWS

INSTALLATION PROCEDURE

• Step 1. Insure that the mounting surface for the lock is smooth and flat, and that the keyhole is perpendicular to the mounting surface.
• Step 2. Attach the lock to the mounting surface using three 1 ⁄4 -20 or three M6- 30 machine screws, depending on the dimensions of the screw threads in the mounting surface.Attach the safe relock device or recommended back plate (see illustration above).
• Step 3. A guide tube should be used on insulated and composite safes. The tube must be cut to a length equal to the safe door thickness plus 3 ⁄16 inch (5mm). This will cause the tube to mate with the pattern surrounding the keyhole and the pattern in the underside of the escutcheon. Remove all sharp edges, burrs, and metal shavings created when the tube is cut.
• Step 4. Attach the escutcheon to the outside surface of the safe door over the keyhole.
• Step 5. Check the operation of the key in the lock. There should be no binding or scraping of the key against the tube or the sides of the keyhole. It should turn easily and smoothly.
• Step 6. Check the operation of the new key(s) in your lock at least three times before closing the safe door.
• Step 7. Make sure the lock bolt does not drag or bind against the safe's boltwork or door frame (rebate).
