Section 7 Initial Startup Procedures

INITIAL START PROCEDURE

The AirDog

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

life expectancy of the system, it is recommended to pre-fill only the water separator with

diesel fuel before initial startup.

7-1. Pre-fill the water separator with diesel fuel.

CAUTION: Check all of the fuel line connections to ensure that they are properly connected

and torque’d and BE ESPECIALLY SURE that the FUEL FILTER IS TIGHT to

PREVENT FUEL SPILLAGE!

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. With fuel or air alone, the AirDog® fuel pump will run very quietly. However, if any

fuel fitting on the vacuum side, between the fuel tank and the AirDog

or the water separator,

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 water separator 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.

A. 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 water separator, 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.

B. Check all fittings, especially the connection at the tank.
