Airmar ST600 Owner's Manual & Installation Instructions

OWNER' S GUIDE
Thru-Hull, Retractable with Valve
Speed & Temperature Sensor
Model ST600
Follow the precautions below for optimal product
performance and to reduce the risk of property
damage, personal injury, and/or death.
WARNING: Always wear safety goggles and a dust
mask when installing.
WARNING: The valve is not a watertight seal! Always
use the insert or blanking plug secured with the safety
wire for a watertight seal.
WARNING: The o-rings must be intact and well
lubricated to make a watertight seal.
WARNING: Always attach the safety wire to prevent the
insert or blanking plug from backing out in the unlikely
event that the cap nut fails or is screwed on incorrectly.
WARNING: Immediately check for leaks when the boat
is placed in the water. Do not leave the boat unchecked
for more than three hours. Even a small leak may allow
considerable water to accumulate.
CAUTION: Never use a fairing with a plastic housing;
the protruding sensor would be vulnerable to damage
from impact.
CAUTION: Never install a metal housing on a vessel
with a positive ground system.
CAUTION: Never pull, carry, or hold the sensor by its
cable; this may sever internal connections.
CAUTION: The arrow on the top of the insert must
point forward toward the bow.
CAUTION: Never use solvents. Cleaners, fuel,
sealants, paint, and other products may contain
strong solvents, such as acetone, which attack many
plastics, greatly reducing their strength.
IMPORTANT: Please read the instructions
completely before proceeding with the installation.
These instructions supersede any other instructions
in your instrument manual if they differ.
Applications
• Plastic housing recommended for fiberglass or metal hull only.
Never install a plastic housing in a wood hull since swelling of
the wood may fracture the plastic.
• Bronze housing recommended for wood or fiberglass hull only.
Never install a bronze housing in a metal hull because electrolytic
corrosion will occur.
Pretest
Connect the sensor to the instrument and spin the paddlewheel. Check for a
speed reading and the approximate air temperature (in appropriate). If there
is no reading(s) or it is inaccurate, check the connections and try again. If
there is still a problem, return the product to the place of purchase.
& INSTALLATION INSTRUCTIONS
Record the information found on the cable tag for future reference.

Tools & Materials
Safety goggles
Dust mask
Water-based anti-fouling paint (mandatory in salt water)
Electric drill with 10mm (3/8") or larger chuck capacity
Drill bit:
Hole saw:
Sandpaper
Mild household detergent or weak solvent (alcohol)
File (installation in a metal hull)
Marine sealant (suitable for below waterline)
Additional washer [for aluminum hull less than 6mm (1/4") thick]

Cable ties
Installation in a cored fiberglass hull (see page 3)
Hole saw for hull interior:
Fiberglass cloth and resin
or Cylinder, wax, tape, and casting epoxy
Mounting Location
CAUTION: Do not mount the sensor near water intake or
discharge openings; behind strakes, fittings, or hull irregularities
that will disturb the flow.
CAUTION: Never mount the sensor directly ahead of a depth
transducer, since turbulence generated by the paddlewheel's
rotation will adversely affect the depth transducer's performance,
especially at high speeds. Mount side by side.
CAUTION: Do not mount in line with trailer rollers or bunks that
may damage the transducer's face.
Turbulence-free water must flow under the paddlewheel at all
speeds. Choose an accessible spot inside the vessel. Allow a
minimum of 200mm (8") of headroom for the height of the
housing, tightening the nuts, and removing the insert.
• Displacement hull powerboats—Locate amidships near the
centerline.
• Planing hull powerboats—Mount well aft to ensure that it is in
contact with the water at high speeds.
• Fin keel sailboats—Mount on or near the centerline and
forward of the fin keel 300–600mm (1–2').
• Full keel sailboats—Locate amidships and away from the keel
at the point of minimum deadrise.
3mm or 1/8"
51mm or 2"
60mm or 2-3/8"
