DETERMINING THE MOUNTING POSITION AND MOUNTING THE OPERATOR
STEP 2 |
| |
Illustration B | ||
Install chain brackets at each end of the gate on the inside | ||
| ||
(operator side) of the gate (see Overview Illustration, page. 12). |
| |
Position the tops of chain brackets no more than 6” above the | String | |
bottom corners of the gate frame and secure with | ||
| ||
Illustration B). The chain brackets will work on gate frames | Quick Release Pin | |
| ||
13/4” to 21/2” in diameter or square tube gates. The | Chain Bracket | |
| ||
provided will work on 2” diameter pipe gate frames. |

Chain Bracket |
| position bracket so that string |
|
| |
|
| will be approximately 7" to 10" |
|
| from ground level at the point where |
|
| the operator will be mounted |
|
| STEP 3 |
|
| Insert a quick release pin into the center slot in each of the chain brackets |
Quick Release Pin | String | (see Illustration C). Tie a string to the end of each quick release pin so |
that the string is tight between the two chain brackets (the string will | ||
|
| be used to align the operator). The string should be |
|
| ground (see Illustration B). The chain brackets can be adjusted up or |
|
| down on the gate to achieve the proper height. The goal here is to set |
|
| the height of the operator so that when the housing is in place it will |
|
| clear the ground by 1” to 4” (see Illustration E). |

(centered between post) | ||
STEP 4 |
| |
Find the center point between the two roller/fence posts (see |
| |
Illustration D). This should coincide with the position of the | Illustration E | |
center point of the operator. Dig a hole approximately 12” x 28” | ||
Level | ||
wide x 28” deep. Place the operator in the hole on its legs and | ||
| ||
position the bottom idler sprockets on the top of the string and | ! | |
level the unit (see Illustration E). Make sure operator is level | ! | |
and plumb. With the unit level and in place, pour the concrete | Sprockets | |
and let set for 24 hours (checking the level periodically) before | String 7" to 10" | |
proceeding to the next step. | above ground | |
| ||
BEFORE POURING CONCRETE: 1] Make sure operator is | Housing | |
| ||
centered between roller posts and aligned with string; and, | 1" to 4" clearance | |
2] Determine method of installing conduit for wiring (see page | Ground Level | |
13)! | ||
