MOUNTING
HOW TO MOUNT:
Slide the body of the unit through the rubber gasket. Insert the unit into the panel. Slide the
brackets up the groove to press against the back of the panel, as shown in "FIG. A". Insert
the screws into the rear of the brackets.
Tighten the screws evenly and alternately. A panel less than .1" may distort if the clamps are
screwed too tightly. Do not over tighten! A normal level of torque is required. Maximum torque
should be 3" pounds.
