Replacing the Fill Line with a NEW Fill Line
Using a wrench on the flats unscrew the QEV (Quick
Exhaust Valve) from the tank. The fill line will be
attached to the QEV. Secure the QEV in a bench
vice. Use a box end wrench on the fill line fitting
to unscrew the fill line from the QEV. Lubricate the
threads on the new fill line, with Loctite
®
545 or
similar sealant, and install it into the threaded base
of the QEV. Use a box end wrench on the fill line
fitting to securely tighten it into the QEV base. DO
NOT use an adjustable wrench to tighten the
fill line. The copper fitting will collapse before it is
securely tightened.
Installing the QEV-Fill Line Assembly
Before installing the QEV-Fill Line Assembly , the Air
Blaster Valve Assembly must be removed from the
tank through the discharge end. Failing to remove
the valve assembly can cause permanent damage
to the fill line. To remove the valve follow instructions
on page 20 - #1 and page 21 - #2. Prior to installing
the fill line assembly inspect the fill line end for burrs
or sharp edges that could cut or tear the o-ring. If
any are found remove with a file. Be sure to apply
Teflon
®
tape or equivalent, such as, Loctite
®
545, to
the QEV threads before inserting the assembly, fill
line first, through the tank opening. Screw the QEV
into the tank fitting. Tighten QEV securely using a
wrench on the flats. Center the fill line in the valve-
flange opening. See next page 25 - letter e.
The length of the fill line is critical. It must be
long enough to extend past the o-ring seal (1) in
the top of the Air Blaster valve cap, but must not
block the valve fill ports on the neck (2) of the valve
cap. Because of variances in the tank fabrication, fill
line and tank fittings, and pipe threads on the QEV,
the newly purchased fill line might be too long. If
the fill line is too long it will block the valve fill ports
causing the Air Blaster not to fill and fire properly.
The following procedure is necessary to check the
fill line length and adjust the length if necessary.
DO NOT skip this step. If the fill line is too
long the Air Blaster will not work and damage
to the fill line could occur making the new fill
line unusable.
