G. Remove the ejector from the ejector manifold assembly by squeezing the

ejector latch release mechanism, and pulling the ejector away from the

manifold.

H. Clean the outside of the ejector with a stiff brush.

I. Remove the two screws to separate the solenoid assembly from the main

valve assembly.

J. Thoroughly clean the plunger with a cloth moistened with denatured alcohol

or electrical contact cleaner. Wipe dry.

K. Flush out the inside of the solenoid assembly, the valve seat, and the cavity

holding the inlet filter screen with denatured alcohol or electrical contact

cleaner. Be careful not to dislodge the “O” ring type seal from its groove. It

is difficult to re-install.

L. Blow out the inside of the solenoid assembly, the valve seat, and the inlet

filter screen cavity with compressed air. Blow from the inside, through the

filter screen, toward the outside.

M. Re-assemble, making sure the “O” ring type seal is in place. The small hole in

the plunger will be located directly over the inlet filter screen. The solenoid

assembly must be oriented so that the electrical cable, the small hole in the

plunger, and the inlet filter screen are all located on the same side of the

ejector.

N. Re-Install an ejector by aligning its inlet and outlet ports with the

corresponding ports on the manifold and pushing in until the latches engage.

Install the electrical connector in the correct mating connector, and push in

until its latch engages.

O. Turn on the power and air.

P. Test the ejector according to Section 3.1.3.

4.8 SERVICING THE COMPRESSED AIR FILTER SYSTEM (See Figure 1-3)

The air filter system for the ScanMasterII consists of a PREFILTER and an OIL

REMOVAL FILTER.

Both filters are equipped with an automatic drain valve. A float actuates the valve

when liquid in the bowl reaches a certain level. The bottom of the valve has 1/8

female pipe threads connected to a tube to carry the liquid away from the machine.

Acting together, the PREFILTER and the OIL REMOVAL FILTER provide very clean air

for machine operation. They both must be inspected frequently and serviced

periodically in order to maintain this quality air. The frequency of this service is

determined by the quality of the air coming from the compressor/dryer.
