1. Remove the cover screws from the air eliminator cover

with a 1/2 inch wrench or socket, and pull the cover, vent

plate and seal ring from the housing.

2. Inspect the raised ridge of the vent port opening in the

middle of the valve plate for marring or debris. Inspect the

seal ring for damage.

3. Replace the seal ring and/or valve plate. Tighten the

cover screws to a torque of 17.5 - 20.5 ft-lbs.

The most common indication of mechanical air and

vapor eliminator failure is leakage in and around the

cover and valve plate area. Common causes of air

eliminator failure are valve plate wear, a broken reed

strip, a damaged cover gasket, and a punctured oat

lled with product.

All internal pressure must be relieved to zero pressure before disassembly or inspection of the strainer, vapor eliminator, any

valves in the system, the packing gland, and the front or rear covers.

6. Slowly crack the tting on top of the differential valve to

relieve product pressure in the system. Product will drain

from the meter system.

7. As product is bleeding from the differential valve, slowly

reopen and close the valve/nozzle on the discharge line.

Repeat this step until the product stops draining from the

differential valve and discharge line valve/nozzle.

8. Leave the discharge line valve/nozzle open while working

on the system.

1. Close the belly valve of the supply tank.

2. Close the valve on the vapor return line.

3. Close the manual valve in the supply line on the inlet

side of the meter. If no manual valve exists on the inlet

side, consult the truck manufacturer for procedures to

depressurize the system.

4. Slowly open the valve/nozzle at the end of the supply

line.

5. After product has bled off, close the valve/nozzle at the

end of the supply line.
