For measurements use template on page 4. Affix paper template to door and follow template instructions in preparing door. Install latch.

1. Pass the cable assembly with connectors through the 1" hole, then mount the exterior housing through door preparation. Make sure that the lock chassis and latch are properly engaged as shown in Figure B.

• 1. Locks are factory assembled with a ring for 1-3/4" door thickness, when lock chassis is firmly against ring. (For 1-3/8" doors, use the EK1038 spacers, one on each side.) When installing thinner than 1-3/4" door thickness, plastic ring must be removed.
• 2. Before installation, use door thickness gauge on template as shown to check lock chassis position. Center of latch retractor should align with mark on gauge for appropriate door thickness.
• 3. Make sure to adjust for correct door handing. To align retractor for desired handing, make sure the outside lever is not attached, and turn the chassis clockwise or counterclockwise until the retractor is in the desired position. Then attach outside lever.
• 4. Assemble outside lever on tube and check that lever engages lever catch before installation.

• 1. Remove screw from Battery Cover to access backplate.
• 2. Feed the cable assembly with connectors through the backplate, lock washer and CableGard™ nut.
• 3. While holding the interior backplate in position, loosely install the two thru-bolts.
• 4. Tighten the CableGard™ nut on the CableGard™ that passes through the door using supplied wrench. When this connection is tight secure the thru-bolts.
• 5. Tear cable wrap to separate wires.

NOTE: USE ONLY ALKALINE BATTERIES, DUE TO PREDETERMINED POWER SETTINGS IN THE LOCK.

NOTE:

• • Dielectric Grease/Silicone lubricant is provided with each lockset by manufacturer. It is recommended to use during installation for all electrical connectors.
• • All wire pairs are color coded to connect with like pair.
• 1. Connect the grey/red wires from the CableGard™ to the grey/red wires from the lever tube. The two remaining pairs are only for the optional sensor-array package, as well as the "reset lock" function. (See programming manual.)
• 2. Connect the red/black wires from the CableGard™ to the red/black wires from the battery pack.
• 3. Place the battery holder over the center grooved stud .
• 4. When properly aligned, push down on the battery holder assembly, engaging the upper part of the hole into the groove of the center stud. This will connect the lower fork with the center post, giving a very secure fit.

• 1. Slide the inside lower housing over the lever tube until it has passed over the lever catch. (Be sure wires are not pinched.)
• 2. Fasten with two brass #8 screws. Once secure, fasten the finished #8 screw at the bottom.
• 3. PUSH ALL EXCESS WIRE LENGTHS DOWN THROUGH THE OPENING AT THE TOP OF THE INSIDE LOWER HOUSING.
