Hardware Installation

The following instructions will guide you through installing the HelmView 750 display.

Inspecting Package Contents

each item for damage (which sometimes occurs during shipping). The items included in the
box are:

HV750 or HVS750 unit
Installation kit – P/N 78-00-0638 includes:

 4 ea. machine screws and flat washers
 4 Nylock nuts

 Installation manual – P/N 00-02-0803
 Operations Manual – P/N 00-02-0805

Dash-Mounted Installation
Tools needed.

 Drill with 5/32” size bit
 Jig Saw
 Wrench or socket 6-32 Nylock nuts (provided) to studs

Preparing the Dash

Determine the location of the HelmView in the dash. Use the Installation Template (included at
the end of the manual) as a guideline to cut a hole in the dash to the specified dimensions. Drill
holes where indicated on the template for the mounting screws.

NOTE: When using the paper template from the manual, if you downloaded this
document from the FW Murphy website, be aware that the pdf file may not
automatically print to scale. When submitting the file for print, you will need to
select “None” for Page Scaling. Check the accuracy of the printed template by

Mounting the Unit

1. Place the backside of the display through the opening in the dash.

2. Use the four screws to line up the unit with the drilled holes.

3. Push the unit through the opening and screws through the drilled holes until the back of
the case is flush.

4. Use the Nylock nuts provided to tighten unit to the dash. Use the appropriate wrench or
socket to tighten. Torque lock nuts to 8-10 inch pounds.

Flush Mounting the Dash

1. Cut the dash to allow for the display without bezel. Make sure enough material remains
to properly secure the display within the dash. Torque the 6-32 Nylock nuts to 5-inch
pounds.

2. Place the display behind dash and line up the four mounting holes on the display with
the holes in dash.

3. Install four bolts and tighten nuts.
