Section 7 Initial Startup Procedures cont’d

INITIAL START PROCEDURE

The AirDog

is a self priming system, however, to prevent potential damage to the system, it

is recommended to fill only the pre-filter with diesel fuel before initial startup.

7-1.

Fill the pre-filter with diesel fuel.

7-2.

Turn the starter key to the on/run position.

NOTE: It may be necessary to momentarily engage the starter in order for the ECM
to energize the AirDog

7-3.

While the AirDog

is operating, bleed the air from the fuel line to the engine by

loosening the fuel line connection at the engine fitting. As soon as the line is purged
of air and pure fuel is observed, properly tighten the fuel fitting.

NOTE: put a rag or

shop towel over and around fitting to prevent splatter. Catch all spilled fuel and
dispose of properly.

7-4.

Start the engine!

RECHECK ALL FUEL FITTINGS FOR LEAKAGE AND PROPERLY TORQUE.
BE SURE ALL FUEL LINES ARE PROPERLY ROUTED TO PROTECT FROM
EXCESSIVE HEAT AND SECURED TO PROTECT FROM CHAFFING AND
ABRASION. RECHECK ALL ELECTRICAL LINES, SECURE AS NECESSARY.

Checking Pump Noise!

NOTE: Each AirDog

has been manufactured in a Quality Controlled process and fully

tested for operation and performance before shipment. This is a very quiet and smooth
running system. However, if any fuel fitting on the vacuum side, between the fuel tank and
the AirDog

or the pre-filter, has been left loose during the installation process, the system

may suck air at an excessive rate and will be very noisy. To check for this problem, unscrew
the pre-filter 3 or 4 full turns and activate the AirDog

by turning the ignition switch to on. If

the AirDog

runs quietly, then excessive air from a loose fitting or leaking water separator

seal is most likely the reason for the excessive noise. Correct as necessary.

The seal groove in the 3” filter is a snug fit and on occasion the seal has been found

to not be fully seated. Remove the pre-filter, remove the seal from the top of the nut

plate. Clean and lubricate the seal groove. Carefully replace the seal in the groove. Be

sure to fully seat the seal.

Check all fittings, especially the connection at the tank.
