(3)Adjustment of dispensing time and interval
time
(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.

(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
pressure is indicated.
3. Set the mode switch to proper position, referring to the adjustment of dispensing time
and interval time.

3. Helpful hints for making Proper deposit
1. Hold the barrel at approximately 60℃(+ or -20℃) angle(FIG1)
2. Lift the dispenser barrel vertically after making a drop, as shown (FIG2)
3. Do not let the syrup flow back into the controller as shown in FIG3.
4. Increase or decrease dot size by either,
Increase or decrease time only,
Or
Increase or decrease pressure only,
Or
Increase or decrease size of the tip.

4. Cautions
1. The dispensed syrup maybe toxic and/or hazardous, refer to manufacturer’s
instructions for proper handling and safety precautions.
2. Compressed air pressure should not exceed 7 bar (100Psi). Otherwise, it will cause
negative effects (damage to objects or injury to the user).
3. Make certain air supply is clean and dry.
4. Syrup should be kept above 5℃to avoid change in density. Otherwise, the syrup
will be hard to dispense and proper dots can not be formed.
5. The air pressure should be regulated at 0.1-0.27Mpa (15-40Psi).
7. Clean the dispenser tip regularly.
8. The suck-back vacuum should be adjusted in conjunction 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 through
air line to inside of the dispenser and cause component damages.
10. Avoid hit the plastic barrel assemblies with hot or sharp objects.
11. Avoid exposingthe dispenser to excessive moisture or solvent.
12. After use, clean the barrel and needles as soon as possible by soaking them in clean
water for 5-10 minutes.

loose connection.
Power light on, does 1.Check air supply and pressure gauge.
not dispense reset the regulator if necessary, remove barrel from
adapter .Depress foot switch to check air flow.
2.If solenoid clogged with foreign object from air compressor,
clean or replace it.
Solenoid buzzes 1.Voltage is too low
2.Air supply is insufficient.
3.Solenoid is not clean.
Burnt fuse 1.Checking fuse specifications.
2.Unplug power input, remove cover, and check internal
wiring for loose connection.
Inconsistent dots 1.Check needles tip, barrel, adapter and material for possible
clogging.
2.Check for air bubbles in the syrup.
3.Check air gauge for air pressure variation.
Dispensing ok, but 1.Check vacuum setting.
