Replace the the Wash Wash Fluid
Replace Replace the Wash
Check the wash fluid bottle level. If the level changes,
service the isolation valve seals.
1. Prepare the isolation system for service. Follow
the Prepare the Isolation System for Service,
page 90.
2. Use a flat blade screwdriver to open the cabinet.
3. Slide the electrostatic shield (82) up to remove.
4. Slide the electrostatic shield (12) to the left to
remove.
5. To remove the isolation valve cover (99), loosen
the top and bottom screws (99a).
6. Disconnect the push-to-connect tube from the
bottle cap of the wash fluid bottle (W).
7. Lift the sealed wash fluid bottle (W) out of the
system. Fill it with clean HydroShield cleansing
solution above the minimum line marked on the
bottle. Replace it in the cabinet.
8. Reconnect the push-to-connect tube to the bottle
cap of the wash fluid bottle (W).
9. Replace the isolation valve cover (99) and tighten
the top and bottom screws (99a).
10. Verify that the electrostatic shields (12 and 82)
are in place, and then close and latch the cabinet
door.

1. Check the ground rod (18):
a. Use Maintenance screen 5 to raise and lower
the ground rod. See
Valve Resets and Test, page
b. Activate the ground rod to raise it and
deactivate it to lower it several times. Listen
for the sound of the ground rod making
contact when raising and lowering. In both
cases, the ground rod should fully retract or
extend in less than 2 seconds.
2. If the ground rod takes more than 2 seconds to
fully retract or extend, use the following steps to
lubricate the cylinder.
3. Relieve pressure in the system. Follow the
Pressure Relief Procedure, page
4. Slide the electrostatic shield (82) up to remove.
5. Slide the electrostatic shield (12) to the left to
remove.
6. Lubricate the ground rod (18):
a. Clip the tie straps that hold the bleed resistor
(24) and ground rod together.
b. Remove the two screws (124), lock washers
(22), flat washers (19), and spacers (123)
that hold the ground rod to the back panel.
c. Tip the ground rod forward and put 5 drops
of lubricating oil in the small air exhaust hole
at the top of the cylinder.
d. To reassemble, tip the ground rod back into
the cabinet. Reattach the screws (124), lock
washers (22), flat washers (19), and spacers
(123). Fasten new tie straps around the
bleed resistor and ground rod.
e. This process may move the wires at the
bottom of the components. After the
reassembly is complete, check the continuity
between the fluid pressure regulator, bleed
resistor, and ground rod.
7. Reinstall electrostatic shields (12 and 82) inside
the cabinet.
8. Close the enclosure doors and reapply pressure
to the system.
9. Repeat step 1. Activate the cylinder 10 times and
then verify that the cylinder speed is less than
2 seconds.
