Gun Setup
12.Set the air pressure.
A. Atomizing air is not used in the UNICARB process.
Close the air control valve (43) by turning it fully
clockwise.
B. Turn the ES ON-OFF lever (26) to ON.

C. Make sure the fluid supply is shut off.
D. Trigger the gun and adjust the air pressure with the
gun air regulator (H); use the Recommended Air
Hose Inlet Pressure chart, below, as a guide.

6 ft ((1.8 m) 40 psi (2.8 bar)
15 ft (5 m) 43 psi (3.0 bar)
25 ft (8 m) 45 psi (3.1 bar)
36 ft (11 m) 47 psi (3.2 bar)
50 ft (15 m) 50 psi (3.5 bar)
75 ft (23 m) 55 psi (3.8 bar)
100 ft (30.5 m) 60 psi (4.1 bar)
NOTE: Using higher than recommended air pressures
can reduce the life of the turbine/alternator. Lower
pressures can be used but may reduce electrostatic
wrap.
E. Check the voltage output of the gun using a high
voltage probe and meter.
NOTE: The gun’s normal high voltage reading is 60 to
70 KV. If a ball end high voltage probe is used, the gun
voltage will rise to about 85 KV. This will happen with
all resistive electrostatic guns.
