Installation
Mounting brackets to the gate posts
There should not be any visible flexing of the mounting points under load.
To spread the load, all mounting holes should be used.
Use fasteners of at least 8 mm diameter x 75 mm length.
Height
Mount the centre line of the bracket either 10 or 5 mm higher than the centre line of the
gate bracket, depending on whether two or three pieces of post bracket are used. This is
to maintain a level actuator.
If the conditions are very dusty, for example around an unsealed driveway, do not mount
the actuators lower than 400 mm above the ground. This is to reduce the likelihood of dust
entering the screw mechanism.
Position relative to gate pivot
Refer to the diagram below for the typical co-ordinates of A and B.
Some guidelines for an easy installation are:
A + B < 340 for up to 90 degrees opening
A + B < 320 for up to 100 degrees opening
A + B < 310 for up to 110 degrees opening
Increase A for a slower but firmer stop open
Increase B for a slower but firmer stop closed
Optimum dimensions are:

The dimension P on the diagram must be:
less than 160 mm for 90 degrees of opening angle;
less than 130 mm for 100 degrees; and
less than 100 mm for 110 degrees.
