Airmar P19 Owner's Manual & Installation Instructions

OWNER' S GUIDE
Thru-hull Depth Transducer
Low Profile, Flush, and Retractable Models
IMPORTANT : Please read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
CAUTION : NEVER USE SOLVENTS!
Cleaners, fuel, paint, sealants, and other products may
contain strong solvents, such as acetone, which attack
many plastics greatly reducing their strength.

Applications

• Plastic housing recommended for fiberglass or metal hulls only.
Never install a plastic transducer in a wood hull, since swelling
of the wood can possibly fracture the plastic.
• Bronze housing recommended for fiberglass or wood hulls.
Never install a bronze housing in an aluminum hull, because
electrolytic corrosion will occur.
• Stainless steel housing compatible with all hull materials.
Recommended for aluminum hulls to prevent electrolytic
corrosion provided the stainless steel housing is isolated from
the metal hull.
• Never install a metal housing in a vessel with a positive ground
system.

Mounting Location

Caution : DO NOT MOUNT near water intake or discharge
openings, or behind strakes, fittings, or hull irregularities.
• The water flowing under the hull must be smooth with a
minimum of bubbles and turbulence (especially at high speeds).
• The transducer must be continuously immersed in water.
• The transducer beam must be unobstructed by the keel or
propeller shaft(s).
• Choose a location away from interference caused by power and
radiation sources such as: the propeller(s) and shaft(s), other
machinery, other echosounders, and other cables. The lower
the noise level, the higher the echosounder gain setting that
can be used.
• Choose a location with a deadrise angle of 20º or less, so the
transducer beam will be aimed at the bottom.
• Choose an accessible spot inside the vessel with adequate
headroom for the height of the housing, tightening the nuts, and
removing any insert (see the table below).
