Airmar P19-12 Owner's Manual & Installation Instructions

OWNER' S GUIDE
Tilted Element Depth Transducer
Models: P19-12º, P19-20º, B22-12º, B22-20º,
B60-12º, B60-20º, SS565-12º, SS565-20º
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 can
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 thru-hull transducer in a wood hull, since
swelling of the wood may overstress the plastic causing a
fracture.
• Bronze housing recommended for fiberglass or wood hulls.
Never install a bronze housing in a metal hull, because
electrolytic corrosion will occur.
• Stainless steel housing compatible with all hull materials.
Recommended for metal hulls to prevent electrolytic corrosion.
A stainless steel housing must be isolated from a metal hull.
• Never install a metal housing in a vessel with a positive ground
system.
• Be sure your transducer model matches the deadrise angle
of your boat. The top of the transducer is imprinted with the angle
(see Figure 1).
12º models for deadrise angles from 8º to 15º
20º models for deadrise angles from 16º to 24º
To measure the deadrise angle of your hull at the selected
Mounting Location, use an angle finder or a digital level
(see Figure 2).
