Figure 5 shows important dimensions and parts of the
vinyl power unit box.
There are two constraints to installing the power unit
box for the 750 Operator:
1. We recommend that you install the power unit box
so that the hydraulic lines between it and the drive unit
are no longer than 20 ft (6 m).
2. The power unit itself must be installed so that the
vent screw is on the top of the unit as shown in Figure
5.
The power unit box that ships with your operator
hinges on the left, but you can reverse the opening
direction of the door if necessary for your installation.
To reverse the opening direction, open the cover, and
then gently pull it off the box. The vinyl hinges can now
be placed in the hinge receptacles on the right-hand
side. Secure the hinges with the screws provided.
You may surface mount the power unit box to a vertical
surface or you may recess it.
Figure 4. Recommended dimensions for the concrete footing and foundation plate, side view
To mount the power unit box use the 3/16-in. holes
provided (relocating the holes in the box will
compromise its integrity).
If you recess the box, keep in mind that hydraulic hoses
and electrical wiring need to enter the bottom of the
box.
Also, recessing must not interfere with the hinge
assembly of the power unit box. You need to keep in
mind the following dimensions.
Height: 14 1/4 in. (36.2 cm)
Width: 10 in. (25.5 cm)
Depth: maximum of 2
1 /2 in. (6.5 cm)
At this time, you also need to remove the vent screw
located on the power unit. The vent screw is in the
middle of the top, left side of the power unit as shown
in Figure 5.
Caution: Failure to remove the vent screw in the
power unit may result in erratic operation of the 750
Operator.
Depth should be a
minimum of 24 in.
