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 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 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 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.
B. Check all fittings, especially the quick connect at the tank.
