Airmar Tilted Element™ Retractable with Valve—DT800: 0°/1 User Manual download pdf

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 YELLOW O-ring must be in place near

the top of the insert to make a watertight seal.

WARNING: To retrofit the insert in a housing without a

valve, the insert must have a BLACK O-ring near the top

to make a watertight seal.

WARNING: The O-rings must be intact and well

lubricated to make a watertight seal.

WARNING: The valve is not a watertight seal! Be sure

the insert or blanking plug is fully inserted into the

housing, and the cap nut is screwed on completely.

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.

WARNING: Stainless steel housing in a metal hull—

Be sure the washer contacts the hull. Do not tighten the

hull nut with the washer against the isolation bushing, as

the housing will not be firmly installed.

CAUTION: Plastic housing—Never use a fairing with a

plastic housing; the protruding sensor would be

vulnerable to damage from impact.

CAUTION: Metal housing—Never install a metal

housing in a vessel with a positive ground system.

CAUTION: Never pull, carry, or hold the transducer by its

cable; this may sever internal connections.

CAUTION: The arrow on the top of the transducer must

point toward the keel or centerline of the boat. This will

align the angle of the element inside the transducer with

the deadrise angle of your hull.

CAUTION: Stainless steel housing in a metal hull—

The stainless steel housing must be isolated from a metal

hull to prevent electrolytic corrosion. Use the isolation

bushing supplied.

CAUTION: Never use solvents. Cleaner, fuel, sealant,

paint, and other products may contain solvents that can

damage plastic parts, especially the transducer’s face.

IMPORTANT: 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 can fracture the plastic.

• Bronze housing recommended for fiberglass or wood hull.

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.

Match Tilt Angle of Transducer to Deadrise

Be sure your transducer model matches the deadrise angle of

your boat at the mounting location. See the top of the transducer

insert for the tilt angle (see Figure 1). To measure the deadrise

angle of your hull at the selected mounting location, use an angle

finder or a digital level (see Figure 2).

• 0° model for deadrise angles from 0° to 7°

• 12° model for deadrise angles from 8° to 15°

• 20° model for deadrise angles from 16° to 24°
