12 Installation Installation In order for the gate operator to function correctly it is important that the gate be level and swing smoothly and freely. If it does not, damage to the operator may result and the life expectancy will be greatly reduced. SW470 gate operators have provisions for both post and pad mounting. However, because of the high torque involved in most swing gate installations, pad mounting is the recommended method. NOTE: Instructions are for right hand operator installation. Left hand is opposite. 0 1 -G 0 66 5 F1 Figure 4 Post Mount for SW470 Operator Only 1 Locate mounting post and electrical conduit locations. The operator cabinet may be installed either parallel or perpendicular to the fence. 2 Excavate required areas for conduit installation and mounting posts. 3 Set mounting post and electrical conduit in place. Knockouts for 3" pipe clamps (not supplied) are provided in the operator. NOTE: Distance between mounting posts and the relative location to gate is very important. 4 Pour cement to secure mounting posts and allow to set for two days before installing power unit.
