Inspecting and Cleaning
Inspect and clean the disassembled components and parts as follows:
1. Use a cotton-swab to remove excess material from the seat extension, lower body, and
connector.
2. Use a cotton-swab and the recommended solvent to further clean the seat extension, lower
body, and elbow connector.
CAUTION! Protect the solenoid valve from contact with material or solvent. Contamination could
cause solenoid failure.
3. Further clean the seat extension, lower body, and elbow connector in a solvent bath ultra-sonic
cleaner.
4. Wipe the large needle clean with a solvent-soaked disposable towel.
5. Use an air gun to blow excess material from the DispenseJet fluid paths into a disposable towel.
6. Carefully inspect the interior of the cleaned components and parts to ensure they are free from
fluid residue and solvent. If parts are not clean, repeat steps 1 through 5 as necessary. When
clean, proceed with step 7.
CAUTION! The needle and seat extension are a precision-fitted set. If one item is worn or
damaged, both items must be replaced. Do not mix parts from the old set with the
new set.
7. Clean the nozzles by following the instructions for "Cleaning the Nozzle" earlier in this section.
8. If desired, clean the solenoid valve by wiping it with a dry disposable towel while it is installed on
the Z-head mounting plate.
9. Carefully inspect the o-rings, u-cup seals, and Teflon gasket for wear or damage. Obtain
replacements as needed.
Reassembling and Reinstalling the DispenseJet
Once the components and parts are cleaned and replacements of worn or damaged parts are obtained, the
DispenseJet can be reassembled and reinstalled to the Dispensing System.
To reassemble and reinstall the DispenseJet:
1. Gather the DispenseJet components, parts, and any replacement parts, on a flat surface.
2. Reassemble the lower body and the upper body as follows:
a. Carefully insert the small o-ring into the lower body.
b. Carefully install the lower body to the upper body and secure using the two hex head
screws.
