2. One material in particular is 3M Professional Grade Rubberized
Undercoating, product code 03584. Another product that
works well is a Dominion Sure Seal rubberized undercoating
such as Gravel Guard Rocker Guard Coating.
3. After the system is completed and tested apply the undercoat
over the complete board using two coats. Do not use lacquer,
enamel paint, or plastic paint for auto bumpers as these
contain chemicals that will dissolve the conformal coating on
the board and cause malfunctions.
How to avoid damaging the display when mounting:
1. If mounting the display in a metal panel or wall there is a risk
of permanent damage due to a jagged opening or too small
of an opening. The metal panel can short circuit the display
rendering it inoperable and requiring the installer to replace
it. Ensure that the edges of the cutout are smooth and that
no material is bent outward where it can dig into the display.
Make sure that the cutout is large enough so that the display
can be easily inserted without having to angle it. There is a ½"
border all around the display to cover the edge of the hole, so
if the hole is a bit larger than the minimum requirement it will
still be covered by the display.
2. When fastening the display to the panel, make sure that it is
centered in the hole and not resting on one edge.
3. Non-conductive mounting spacers are available to help
prevent damaging the display. Contact Garnet for further
details.
How to avoid damaging the display or pump switch due to
excessive current:
1. Please be aware that the water pump switch circuit has a
limitation on current draw of 7.5 amps, some large pumps
can draw over 10 amps. These high drain pumps must use a
relay or the display console printed circuit will overheat and
damage the display permanently.
2. If the 12V supply line from the electrical panel does not have
a 7.5 amp fuse rating, please be sure to install the supplied
fuse holder with a 7.5 amp automotive style fuse inline on the
+12V red wire.
