Chamberlain 2000E - 1/3 HP - Manual (Page 4)

BEFORE YOU BEGIN, PLEASE TAKE SOME TIME TO CAREFULLY EXAMINE THE ILLUSTRATIONS OF A
TYPICAL GARAGE DOOR OPENER INSTALLATION ON BOTH A SECTIONAL AND A ONE-PIECE DOOR.
Some installation instructions vary for sectional and one-piece doors. Follow only those instructions which apply
to your door type.
Do you have a finished ceiling in your garage? If so, you will need a support bracket and additional fastening
hardware. Refer to Step 4, Page 13 for specific requirements.
Do you have a lightweight or metal door (or does it have glass panels)? If so, horizontal and vertical
reinforcement is required. Refer to Step 8, Page 17.
If possible, install the door opener 2.1m or more above floor with the manual release handle mounted
1.8m above the floor.
