Magnum Venus Plastech DP-1000 (EPO3) - Manual (Page 21)

(Figure 19. Almost Normal Spray Pattern) (Figure 20. Normal Spray Pattern)
Pattern Too Wide:
Heavy misting is seen and smelled, and there is significant overspray (material laid down
beyond the main pattern). The heavy frothing does not disappear within 2 minutes (see Figure 21)
Note: This is the most common problem in running the unit.
Solution F: Reduce the MAIN PRESSURE until the fan pattern fails, then increase the pressure until the
proper fan pattern returns.
Note: If frothing remains, the pressure is excessive and should be reduced. At this point, increase pressure to
the optional air assist nozzle from the front panel regulator labeled AIR ASSIST.
A properly adjusted air assist nozzle distributes material evenly across the spray fan without excessive fuming
or misting. If air assist adjustment does not produce a good pattern, increase the temperature at the in-line
heaters until the pattern improves. Upon completion of testing the spray pattern, pump accumulators should
be charged to their proper operating pressures.
