Setup - Graco 980 Instructions Manual

Connect the Fluid and Air Supply
NOTES:
D The HVLP Cart/Compressor provides the air supply
for the remote pressure pot.
D Circled letters in Fig. 1 indicate hose line
connections.
NOTE: Model 980 HVLP spray guns differ from
traditional non-bleeder guns by the constant low
velocity airflow designed to prevent restriction and
plugging of aircap orifices.
1. Connect gun air supply hose (A) between turbine
air outlet (B) and gun air inlet (C). DO NOT use
wrench to tighten connections; hand tighten only.
See Fig. 1.
2. If using a spray gun cup (D):

If using accessory remote pressure pots (F):
Connect fluid supply hose (G) between remote
pressure pot fluid outlet (H) and gun fluid inlet (E).
Connect pressure pot air hose (J) between
pressure pot air regulator inlet (K) and the cart
compressor air outlet.
