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 exposing the 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.
