Installation
Display GS550
Important! Do not crack or puncture the membrane fascia. The GS550 display is splash
and rain proof. Waterproofing depends in part on the integrity of the membrane.
Important! Do not power wash the display. The GS550 display is not designed to
withstand high-pressure washing devices that can erode the membrane fascia seal or
create fissures in the membrane fascia. Power washing the display voids warranty
coverage.
Mounting Bracket
Step 1. Determine the mounting location. The display may be installed either inside or outside
the cab. It can be mounted on the dash, on a sidewall, or on the ceiling of the cab. To
ensure reliable radio communication between sensors and the GS550, the antenna
must not be in contact with metal and must have a direct and clear line of sight to the
antennas of all sensors. The mounting bracket requires a flat surface of at least
2 inches in diameter on both sides and where the back of the surface is accessible in
order to tighten the nuts.
Step 2. Drill ¼ inch boltholes through the mounting surface with a ¼ inch bit following either the
three, or the four, hole configuration.
Step 3. Install the display with the supplied bolts. Add the washers and the lock nut behind the
mounting surface and tighten sufficiently.
Tip: If the nuts are on the outside of the cab, caulk with silicone between the washers and the cab
to prevent water entry.
