Alternate Installation - Chamberlain AGS 3000 Installation Instructions Manual

Alternate Installations
REAR MOUNT PLACEMENT
CHAIN ARRANGEMENT
pg 12
The rear mount installation is an
excellent way to conceal the chain or opera-
tor. The operator is placed in the extreme rear
of the gate as shown and the chain never
goes across the driveway. The chain only
goes from the gate operator to a post or wall
beside the driveway. Place shortest edge of
the operator 3" from the rear end of the gate
and place the long edge of the operator 3-1/2"
away from the gate toward the wall.
The chain will form a continuous
loop, going around the drive sprocket on the
operator, and around the idler sprocket on the
post or wall. Only one gate bracket is
required on the rear edge of the gate where
both ends of the chain come together and
attach to the bracket. To prepare the AGS
3000 for a rear mount installation, remove one
or both idler sprockets from the operator.
Neither idler sprocket will be needed on the
gate operator. For the idler sprocket, an
ES130 End Sprocket Assembly with chain
guard may be used. Alternately, an idler
sprocket that was removed from the gate
operator may be used. It is recommended
that a cover be placed over the idler sprocket
in this case for safety.
