AFTER APPLYING SUPPLY AIR TO UNIT
1. To build fluid pressure, turn on the recirculation gun block as long as lines are
being returned back to material source.
a) Note: If equipped with UPMS-xxxx system. Check that ratios are
correct at this point and adjust if necessary.
b) Make sure that there is not a “dive” in the pump down stroke.
2. If there is no recirculation package installed, then do the following. Start with
pump air pressure at zero. Push the priming button down and hold. Slowly
increase pump air regulator pressure. Do not exceed ether one of the fluid
pressures established from (Final settings) section.
3. Check for any material or solvent leaks on the entire unit.
4. Once air has been purged from system, turn off recirculation or release priming
button.
5. Using the dispensing gun. Dispense small amount of material into waste bucket,
making sure that both material streams are constant with no interruptions or air.
6. Flush gun head and wipe down face with solvent.
7. Install mix chamber and any other mixing devices supplied with unit.
8. Set pump pressure to correct operating range.
9. Spray/Pour small sample to check for correct dispensing pattern, gel time and
cure.
10. Flush gun head.
11. Install mixers and nozzles to dispense gun head. To balance the fluid pressures,
dispense materials into a waste container, typically this should only take a couple
of pump strokes.
12. Check fluid pressures as set-up during the (Final settings) section before going
into production.
