Startup

This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection and
splashing, keep fingers and other body parts away
from the spray tip.
To avoid injury from toxic fluids or fumes, such as
splashing in the eyes or on skin, wear appropriate
personal protective equipment.
1. Make sure the air line and the cables are correctly
connected to the system.
2. Locate the Power Switch (BD, page 9) at the left of
the PSM Control Box (F, page 7) and turn the
power on.
3. Press the Control Power on button (BB, page 9).
4. Go to the Advanced Screen of the PSM Control
Box (F, page 7), then select 'Reload valve' to turn
on Reload Valve (AD, page 8).

5. Adjust the Pressure Regulating Valve (C, page 7) so
the air pressure provided by the customer is at
least 80 psi (0.6 MPa, 6 bar), and no higher than
100 psi (0.7 MPa, 7 bar).

NOTE: If needed, add the pressure relief valve to
reduce pressure to 100 psi (0.7 MPa, 7 bar).
6. Perform Prime the System on page 39.
7. Dispense several full stroke shots until the PSM
Machine (H, page 7) is free of air and there is no
leakage at the Dispense Valve (AB, page 8) after
shutoff.
NOTE: Very viscous, compressible materials may
continue to leak after system is primed. Reduce flow
rate as required to produce air-free dispensation. Very
thin materials may require tilting the valve greater than
45 degrees and dispensing shots until material is
air-free.
NOTE: Air entering the machine should be filtered.
