Spraying/Dispensing
Air is supplied to spray gun with gun piston
safety lock and gun fluid manifold valves A
and B closed (if present).
1.
Set function knob to Stop/Park
.
2.
Set Recirc/Spray valves to Spray.
3.
Turn function knob to Pressure Adjust
.
Keep turning to the right until fluid pressure
gauges show desired pressure.
4.
Check fluid pressure gauges to ensure proper
pressure balance. If imbalanced, reduce pres-
sure of higher component by slightly turning
Recirc/Spray valve for that component toward
Recirc, until gauges show balanced pressures.
The pressure imbalance alarm (Status Code 1)
is inactive for 10 sec after entering spray pres-
sure mode, to allow time to balance pressures.
Watch gauges for 10 sec to be sure pressure
holds on both sides and pumps are not mov-
ing.
5.
Open gun fluid manifold valves A and B
(impingement mix guns only).
On impingement guns, never open fluid mani-
fold valves or trigger gun if pressures are
imbalanced.
6.
Disengage piston safety lock.
7.
Test spray onto cardboard or plastic sheet. Ver-
ify that material fully cures in the required length
of time, and is the correct color. Adjust pressure
and temperature to get desired results. Equip-
ment is ready to spray.
In this example, B side
pressure is higher, so
use the B side valve to
balance pressures.
