mounted on the compressor’s control
manifold.
2. Remove the top securing screw [

valve connected to the unit, and gently pull
the connector away from the solenoid block’s
connection pins [

].
3. Remove the wires connected to the valve
connector head [

4. Remove the collar from the pneumatic tube
connection [

] to separate the tube from the
body.
5. Remove the four (4) screws [
H
] securing the
solenoid block to the unit.
6. Position the new solenoid valve body so that
the four (4) mounting holes of the valve body
align with the four (4) holes on the unit
mounting surface. Note that the screw [

]
side of the new valve faces into the
compressor unit.
7. Use the four (4) mounting screws from the kit

connector head.
10. On the wire, replace the old connector collar
with the new one from the new connector
head.
11. Run the collar up the wire, and secure it to
the valve connector head.
12. Position the connector head onto the valve
body making sure the pins align correctly
before applying pressure.

6.6.9 DRAINING THE AIR TANK
Refer to
Figure 6-13
. The air tank reservoir may
accumulate a moisture build-up on the inside due to the
compression of air. The air tank should be checked daily
and allowed to drain by opening the drain cock on the ball
NOTE
If operating the machine in high
humidity, the drain valve can be left
partially open to relieve water build-up
during operation. This water may contain
a small amount of oil.
