Section 7 Initial Startup Procedures
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 water separator with diesel fuel.
7-2.
Turn the starter key to the on/run position.
7-3.
While the AirDog
®
is operating, bleed the fuel line to the engine of air 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 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 wet 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 pre-filter seal is most likely the reason
for the excessive noise. Correct as necessary.
A.
The seal groove in the 3” water separator 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 quick connect at the tank.
