(3)Adjustment of dispensing time and interval
time
Mode switch on the rear panel of the unit
can be adjusted according to th
following table to suit different needs.
(a). Adjustment of dispensing time and interval time.
The dispensing time control button is located on the front panel of the unit.
The dispensing time can be set directly. Press the “+” button, and the
corresponding digit will increase by one. Similarly, press the “- ”button,
the corresponding digit will decrease by one. There are four digits in the
display, with a range from 0.01 second to 99.99 seconds, and the resolution
is 0.01 second.
(b). Interval Time Setup
The interval time control button is located on the front panel of the unit.
The interval time can be set directly. Press the “+” button will increase
the interval by one. Similarly, press the “- ”button will decrease the
interval by one. There are two digits in the display, with a range from 0.1
second to 9.9 seconds, and the resolution is 0.1 second.

With pedal switch pressed, dispense at controlled
time continually, or it will stop dispensing.
Dispense at controlled time continually and
automatically.
Note: Dispensing at controlled time means dispensing according to set dispensing time
and interval time.
(4)Internal air pressure control
The air pressure regulation knob controls internal air pressure. Air pressure
at 0.1-2.7bar (1-40Psi) is normally used.
(5)Vacuum control
The vacuum control knob regulates the ending dot in the air reflection, avoid connected
dots. Turn the knob clockwise will increase air reflection , otherwise, it will decrease.
(6)Set up
1. Connect the 7 bar dry and filtered air supply to the unit’s air input
plug.
2. Fill the barrel with syrup. Make sure the syrup level is not over the FULL
line,
(6)Operation
1. Turn the unit “on” by switching the red power to on position.
2. Pull the air pressure regulator knob outward and turn clockwise until the desired air
pressur e is in di ca te d.
3. Set the mode switch to proper position, referring to the adjustment of dispensing time
and interval time .
3. Helpful hints for making Proper de posit
1. Hold the barr el at approximately 60℃(+ or -20℃) angle(FI G1)
2. Lift the dispenser barr el vertically after making a drop, as shown (FIG2)
3. Do not let the syr up flow back into the controller as shown in FIG3.
4. Increase or decre ase dot size by ei t h er,

4. Cautions
1. The dispensed syrup maybe toxic and/or hazardous, refer to manufacturer’s
instructions for proper handling and safety precautions.
2. Compr essed air pressure s hould not ex ceed 7 bar (100 Psi). Oth erwise, it wi ll cause
negative effects (damage to objects or injury to the user).
3. Make certain air suppl y is clean and dr y.
4. Syru p should be ke pt above 5℃ to avoid change in density. Otherwise, the syrup
will be hard to dispense and proper dots can not be for med.
5. Th e air pressure should be r egula t ed at 0.1-0. 27Mpa ( 15-40Psi).
7. Clean the dispenser tip reg ul arly.
8. The suck-back vacuum should be adjusted in conjunct ion with air pressure, dispensing
cycle and drop size. Too stronger vacuum will break the dispensed lines, cause running
back of the syrup through the controller, resulting in permanent damages to the unit.
9. Avoid turning barrels upside down or lay down on its side. Syrup may run t hrough
air li ne to insid e of the di s penser and ca use comp onent damages.
10. Avoid hit the plastic barrel assemblies with hot or sharp objects.
11. Avoid exposing the dispenser to excessive moisture or solvent.
12. After use, clean t he barrel and needles as soon as possibl e by soaking them in clean
water for 5-10 minutes.
