Tube Clamp Assembly 7-3
P/N 108755-US, Manual revision: AA
3. Unplug the power cord from the outlet. Remove the four nylon screws
from the clamp body.
4. Gently pull the clamp body (with the solenoid assembly attached) out of
the neck of the Shaker. Gently remove the gasket by pulling it off over the
clamp body and save the gasket for reinstallation of the clamp body. Al-
low the clamp body/solenoid assembly to rest on the shroud of the Shaker.
5. Disconnect the Shaker wiring harness and the solenoid wiring connec-
tion.
6. Inspect the tube holder for security and cracks.
7. Verify that the solenoid has not come loose from the clamp body. If it has,
use the self-tapping screw to replace.
8. While holding the clamp body in a downward position, push in on the
back of the solenoid plunger. The plunger should move in and out freely.
Rotate the plunger 1/16th turn clockwise and repeat the motion. The
plunger should move in and out freely. Repeat the process above at least
16 additional times. The plunger should move freely at each point it is
tested. If the solenoid sticks or is sluggish at any point, slightly loosen the
two screws that secure the solenoid to the clamp body to relieve binding.
Tighten until snug, repeating the above test to verify its motion. This pro-
cedure may need to be repeated several times to achieve the desired af-
fect.
9. Verify that the rubber gasket around the neck of the Shaker provides a
good seal to prevent fluid from entering the Shaker body.
10. Remove the mounting screws that secure the solenoid to the clamp body.
Update if necessary to the new, self-tapping screws. Grease when reas-
sembled. Verify the tube clamp has not worked loose from the solenoid
shaft. Remove tube clamp from solenoid shaft to inspect and clean.
11. Verify solder joints on solenoid are intact. Set aside solenoid shaft. Re-
move two Phillips head screws that secure tube holder to clamp body. Up-
date to the self-tapping threads (a large hole must be drilled).
12. Clean the surfaces of the Shaker using a soft cloth dampened with a mild
detergent, diluted disinfectant, or alcohol. Never spray solutions directly
onto the Shaker, but spray on a damp cloth and wipe surface clean.
Bleach solutions are extremely caustic and can damage a variety of mate-
rials. Full strength bleach should never be used on the Shaker. If bleach or
bleach solutions are used, it is recommended that bleach be diluted per
user standard operating procedures. The Shaker must then be wiped down
with a damp cloth to remove any bleach residue.
13. Inspect clamp body for cracks. If any are found, replace clamp holder.
14. Reinstall, tighten snug and verify tube holder is flat against the clamp
body. Set aside.
