CAST

™

App for DST810

Download the Airmar CAST App to evaluate your

boat’s performance by viewing and analyzing

DST810 sensor data. With the CAST App you can

perform depth, speed, temperature, and attitude

calibrations.

Install the CAST App on your iOS or Android device with

Bluetooth

connectivity. Then view available NMEA data over a

wireless or network connection. Within the Cast App, you can link

to and download the CAST App User Guide.

Downloading the CAST App

1. Go to the App Store or Google Play Store.

2. Search on the word Airmar.

3. Download the free CAST App

Important

Read the instructions completely before proceeding with the

installation. These instructions supersede any other instructions in

your instrument manual if they differ.

Applications

• Best performance on hull deadrise angle through 7°.

Accommodates up to a 22° deadrise angle.

• Plastic housing recommended for fiberglass or metal hull only.

Never install a plastic housing in a wood hull, since swelling of

the wood can possibly fracture the plastic.

• Bronze housing recommended for fiberglass or wood hull.

Never mount a bronze housing in a metal hull because

electrolytic corrosion will occur.

• Stainless steel housing compatible with all hull materials.

Recommended for a metal hull to prevent electrolytic corrosion

provided the stainless steel housing is isolated from the metal

hull.

Pretest

Connect the sensor to the instrument and spin the paddlewheel.

Check for a speed reading and the approximate air temperature. If

there are no readings or they are inaccurate, check all the

connections and repeat the test. If there are still no readings or

they are inaccurate, return the product to the place of purchase.

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 glasses, a dust mask, and

ear protection when installing.

WARNING: The valve is not a watertight seal! Always

install the insert or blanking plug. Be sure it is fully inserted

into the housing and the cap nut is screwed on completely

for a watertight seal.

WARNING: All the O-rings must be intact and well lubricated

to make a watertight seal.

Do not dry fit the insert in the

housing. Attempting to install the insert without lubricating all

O-rings will damage them, possibly preventing full insertion

and a watertight seal.

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

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: 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 to align with the water flow.

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:

Stainless steel housing in a metal hull

—A

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.

CAUTION: Never power sand or pressure wash the sensor.

It may weaken the structure or damage the internal

components.
