Safety

Safety Guidelines

The following are safety precautions that personnel must understand and follow when using or
servicing this product. These precautions may or may not be included elsewhere in this manual.

1. POTENTIAL SHOCK HAZARD - Repair procedures on PACE products should be
performed by Qualified Service Personnel only. Line voltage parts may be exposed
when the equipment is disassembled. Service personnel must avoid contact with these
parts when troubleshooting the product.

2. To prevent personnel injury, adhere to safety guidelines in accordance with OSHA and
other applicable safety standards.

3. Always use PACE systems in a well ventilated area. A fume extraction system such as
those available from PACE are highly recommended to help protect personnel from
solder flux fumes.

4. Exercise proper precautions when using chemicals (e.g., solder paste). Refer to the Material
Safety Data Sheet (MSDS) supplied with each chemical and adhere to all safety precautions
recommended by the manufacturer.

5. Do not exceed 7 Bar (100 PSI), otherwise damage to equipment, materials, and the operator
could occur.

6. Personnel who handle dispensing materials should wash their hands and face thoroughly
before eating, smoking or using rest room facilities.

7. Proper training should be given to personnel handling these materials.

8. The use of Safety Glasses is recommended when loading the barrels.

System Set-Up
Hose/Barrel Connection

1. Connect the shop air supply to the unit’s air input plug.

2. Attach the ridged end of the male quick connect hose mount Fitting to the Air Hose.

3. Insert the male hose mount fitting (attached to Air Hose) into the
female Dispensing Output Pressure Fitting.

4. Slide the Hose Clamp over the free end of the Air Hose. Push
clamp back 1 inch from the end of the Air Hose.

5. Attach the free end of the Air Hose to the nipple on the Barrel
Adapter (10 cc adapter is supplied).

6. Secure the Air Hose to the Barrel Adapter by sliding the Hose
Clamp down over the Air Hose/Barrel Adapter connection and screwing clamp down to secure in
position.

7. Attach the Barrel Adapter to a preloaded barrel (not supplied). Place the barrel in the
Dispenser Cubby.

10. Insure that the foot pedal is connected to the FOOT PEDAL Receptacle on the rear panel.

Material Loading

PACE recommends the use of preloaded barrels whenever practical to
minimize any handling or safety precaution requirements. When
loading is required, adhere to all precautions recommended by the
material manufacturer. Refer to the Material Safety Data Sheet
supplied with each material for information on important safety
procedures and a listing of any toxic chemical elements.

Loading of low viscosity materials are easily accomplished by placing
an empty Barrel (with barrel tip cap installed) into the Pik & Paste.
Pour the material slowly into the barrel using a Squeeze Bottle or small
funnel.

Caution: Fill the Barrel to a level of no more than 2/3 or the Barrel capacity. Dispensed amount

variations will be avoided and the material will be prevented from getting on the Barrel
adapter. Do not allow the Barrel to tip upside down or lay flat. Damage may occur to
the motor pump if fluid leaks back into the system through the air hose.

System Power Up

Plug the prong end (male end) of the power cord into an appropriate 3 wire grounded AC supply
receptacle.

NOTE: Make sure the power supply socket is properly grounded with the corresponding volta ge.

Operation

1. Turn the unit “on” by switching the red power button to the on position.

2. Pull the air pressure regulator knob outward and turn clockwise to increase the
air pressure until the desired pressure is indicated.

NOTE: The air pressure output should generally be used between 0.1-2.7bar

(1-40Psi).

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

4. Adjust the dispensing time via the buttons on the front panel. To
adjust, press the “+” button to increase the time and press the “-“
button to decrease the time. There are four digits in all; with the range
from 0.01 second to 99.99 seconds, and the resolution is 0.01 second.

5. Adjust the Interval Time via the buttons on the front panel. To adjust,
press the “+” button to increase the time and press the “-“ button to
decrease the time. There are two digits in all; with the range from 0.1
second to 9.9 seconds, and the resolution is 0.1 second.

6. Adjust the vacuum via the Vacuum Control Knob, which is located on the front panel. Turn
clockwise to increase the vacuum and turn the Vacuum Control Knob counterclockwise to
decrease the vacuum. The vacuum should be adjusted during the dispensing cycle. This
function is used to prevent the material from oozing after the material
has been dispensed.

NOTE: The barrel material will not drip or ooze unless it has a low

viscosity level. I dripping or oozing does not occur, leave the
Vacuum Control Knob set the fully counterclockwise position.
To high of a vacuum setting could case the material to be
sucked back into the system thus possibly damaging the
station.

7. Insure that the proper material (in barrel) and tip have been installed.

8. Wipe any material residue from the end of tip.

All Rights Reserved

9. Hold the barrel at approximately 60° (+ or -20°) angle, rest the tip on a piece of paper and
dispense a small amount of material. This initial dispensing will fill the tip with material.

10. Depress the foot pedal to dispense material.

11. Place barrel in Dispenser Cubby when dispensing operation is
complete.

NOTE: Condensation may occur in the air hose after extended

use. This is a normal occurrence. To remove the
condensation, disconnect the air hose from the barrel adapter and actuate the dispense
pump. The air pressure will blow the condensation from the air hose.

Adjustment of Dispensing Modes

The Mode Switch is located on the rear panel of the unit. Please refer to the table below for the
settings.

NOTE: Dispensing at controlled time means dispensing accordin g to set dispensing and interval

times.

Helpful Hints for Proper Dispensing

PACE recommends that the operator become familiar with the operation of the dispenser by first applying
the material to a piece of paper or scrap PC board. Use this method to obtain the desired results for each
dispensing material and application.

1. Do not permit the liquid to flow back into the controller as shown.

2. Increase or decrease the size of the dots by either, increasing or decreasing the time,
Or
Increasing or decreasing the pressure,
Or
Increasing or decreasing the size of the tip.

3. Make certain that the air supply is clean and dry.

4. The output air pressure should be regulated at 0.1-0.27 Mpa (15-40 PSI).

5. When dispensing different dot sizes, select a tip/time combination, which dispenses small dots.
These small dots may be dispensed in multiples to provide the deposition amount required. Use
of the feature in this manner can eliminate frequent tip changes and dispense cycle time
adjustments.

6. In situations where the metal tip may scratch or damage the work, install a short section of heat
shrinkable tubing or sleeving. The tubing (or sleeving) should extend 1.5 mm (1/16”) past the tip
end.

7. Keep all dispenser components clean to prevent clogging and/or irregular deposition.

All Rights Reserved

8. Avoid turning barrels upside down or laying barrel, so that material may run through the vacuum
line to the internal components.

9. Do not allow the barrel assemblies to contact hot or sharp objects.

10. Avoid exposing the liquid dispenser to excessive moisture or solvent situations.
NOTE: Dispose of all tips and barrels after use. Always use new tips and barrels to prevent

contamination, insure cleanliness and provide consistent, repeatable material deposition.

Tip Selection

Selection of the proper tip for the application is essential to obtain the optimum deposition rate and
amount. Check the specifications of the material manufacturer for recommended tip sizing. The tip size
and duration of the dispense cycle determine amount of material deposition (dot or bead size). Dispense
several dots (or beads) onto a piece of paper or scrap PC board to check for desired results.

Corrective Maintenance

Most malfunctions are simple and easy to correct.
