If you choose not to use the piston, please follow these instructions carefully:
1.
While holding the barrel upright in one hand, twist on an orange tip cap. Using the small funnel, fill
about 2/3 full with your fluid.
2.
Open the safety clip and attach the barrel to the adapter.
3.
Close the safety clip as tight as possible.
4.
Increase vacuum by turning vacuum control knob counterclockwise and set to 1.5 on the vacuum
pressure gauge.
5.
Then, without tipping the barrel upside down, remove the tip cap and attach the 25 gauge (red) tip.
6.
Open the safety clip. Your material may begin to bubble. Reduce vacuum by turning vacuum control
knob clockwise.
7.
If a drop begins to form at the end of the tip, slowly turn the vacuum control knob counterclockwise
to stop the drop from growing. Wipe the tip and adjust vacuum as necessary.
Now the fluid is in proper balance. It does not bubble or drip.
Repeat tests as before, keeping the air pressure low and adjusting the time for different deposit sizes. Contact
Drifton service if you have any questions.
Two things to remember (if you do not use the piston. when dispensing thin fluid)
1.
Do not tip the barrel upside down or lay flat, this will cause the liquid to run into the dispenser.
2.
When changing tips or attaching a tip cap, snap the safety clip completely closed to prevent any
dripping or bubbling.
5. Piston function
The pistons make barrel filling easier. As you load the fluid in, air is
trapped in the bottom and throughout the fluid. Simply insert a piston
and gently press down on the fluid as far as possible. This action forces
out most of the air and results in consistent deposits.
- Piston prevents fluids backflow
- No air gap when using the piston
Using piston has several advantages
1.
Vacuum adjustment is much less sensitive.
2.
The piston prevents fumes from the fluid being exhausted
into the work environment.
3.
The piston prevents fluid backflow into the dispenser if the
barrel is inadvertently turned upside down.
4.
Using the piston makes it easy and safe to change tips
without dripping.
