Airmar Technology Corporation T42 Owner's Manual & Installation Instructions

OWNER' S GUIDE
Thru-Hull, NMEA 0183
High-Precision Temperature
WARNING: Always wear safety goggles and a dust
mask when installing to avoid personal injury.
WARNING: The power must be OFF before wiring if
the instrument is already connected to a power source
to avoid personal injury or death.
WARNING: The power supply voltage must be
12 VDC. Any other voltage may damage the sensor
and/or result in fire, causing damage to the boat,
personal injury, and/or death.
WARNING: A safe installation requires a 0.5 amp fast-
blow fuse or circuit breaker. Failure to do so may result
in fire, causing damage to the boat, personal injury,
and/or death.
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 can allow considerable water to accumulate.
CAUTION: Never install a metal sensor on a vessel
with a positive ground system.
CAUTION: Never install a bronze sensor in a metal
hull because electrolytic corrosion will occur.
CAUTION: Never pull, carry, or hold the sensor by its
cable; this may sever internal connections.
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: Read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
