Recirculation Setting

Fluid can be circulated up to the mix manifold with the 
addition of Graco’s Circulation Kit. Consult your distribu-
tor. 

To set the ProMix Easy to circulate:

To terminate circulation, press 

.

To begin circulating again, press 

.

To begin spraying, turn function knob to 

, reset 

system to desired ratio, and adjust pump to spray pres-
sure.

During recirculation only the pump runs; A and B 
dispense valves do not operate. Material pumped 
in recirculation mode is not counted by the total-
izer.

1.

Decrease the pump air pressure supply to the mini-
mum required to maintain the desired circulation vol-
ume.

2.

Turn function knob to 

.

3.

Press .

CAUTION

Be sure recirculation valve does not leak material 
back to fluid supply while spraying.
