3.3 Installation Procedure
• Prepare the mounting surface by making sure it is clean and flat.
Note(MDS-1R/8R/9R)
A template is provided for making fixing holes at installation site.
However it is recommended to check if the template matches with actual unit just in case the
template has dimensional change by reproduction or swelling by moisture.
• Use the template provided to mark the location of four mounting holes. Align the template
squarely with the center line of the vessel and with the arrow pointing forward.
• Drill four 1/2 in. (13 mm) diameter holes through the mounting surface.
• Check that each bolt (with lock washer and flat washer) protrude through the mounting
surface at least 5/16 in. (8 mm) but less than 9/16 in. (15 mm). The scanner will be
damaged if bolts protrude more than 9/16 in. (15 mm).
• Apply sealant around each mounting hole.
• Place the RADARpc scanner unit on the mounting surface. Orient the scanner with the
index mark on the housing facing forward (cable gland facing aft).
• Install and tighten four M10 x 25U (M10 x 1 in.) mounting bolts.
• Uncoil the scanner cable.
• Secure the cable near the scanner to support the weight of the cable and prevent strain on
the watertight cable seal. If the cable is to pass through tubing or a bulkhead, protect the
unfinished end. Do not use the unfinished wires or fabric braid to pull the cable. •
Route
the cable to the operator’s location, securing it at appropriate points along the way. Make a
drip loop and apply sealant at the entry point of an exterior bulkhead.
