Prime Empty System
3A0420V 25
Prime Empty System
Prime A and B Fluids
NOTE: The equipment is tested with mineral oil at
the factory. If necessary, flush out the oil with a
compatible solvent before spraying. See
Empty and
Flush Entire System (new system or end of job),
page 31.
Do not install the gun spray tip yet. To avoid splash-
ing, use the lowest pressure possible to prime.
1. Condition the materials prior to adding to the hop-
pers (J). Ensure that the resin materials are thor-
oughly mixed, homogenous, and pourable prior to
adding to the hopper. Stir the hardeners back into
suspension prior to adding material to hopper.
2. Fill the A and B reservoirs with proper materials. Fill
the A side (blue) with major volume of material; fill
the B side (green) with minor volume of material
(unless 1:1 mix ratio).
3. Move the recirculation lines (U) to empty containers.
4. Close the dual shutoff handle (AE) and open the cir-
culation handle (AC).
5. XP Systems only: Open the main air shutoff valve
(CA). Then slowly open the air regulator (CB).
6. XP-h Systems only: Set pump valve on. Then turn
down the pressure control knob.
7. Dispense fluid into the containers until clean fluid
comes out of the A and B recirculation lines.
8. Decrease air pressure. Close the main air shutoff
valve (CA).
9. Move the recirculation lines (U) back to the correct
hopper (J).
10. If using heaters, heat fluid throughout system before
spraying. See Recirculate Prior to Spraying or
Re-Prime After a Pump Runs Dry , page 27.
Wear gloves when using flush solvents and/or if the
fluid temperature exceeds 110°F (43°C).
