System Air Supply
See Figure 3-4. Supply compressed air to the controller at 4.0 − 7.6 bar
(58 − 110 psi).
NOTE: Compressed air should be supplied from an air drop equipped with
a self-relieving shutoff valve. The air must be clean and dry. A refrigerant or
desiccant-type air drier and air filters are recommended.
System Ground
Locate the ground wire with clamp shipped with the controller. Attach the
ground wire terminal to the ground stud at the rear of the controller, then
attach the clamp to a true earth ground or grounded booth base.
Gun Connections
1. See Figures 3-4 or 3-6. Connect 4-mm clear electrode air wash tubing to
the air wash connectors on the gun controller panels.
2. Connect the gun cables to the receptacles on the gun controller panels.
Tighten the cable nuts securely.
3. Route the air wash tubing and gun cables to the spray guns, bundling
them together with spiral-cut tubing. Protect the bundles from damage
and kinking.
4. See Figure 3-8. Connect the wash tubing to the barbed fitting (3)
(bar-mount gun) or tubing union (4) (tube-mount gun).
5. Connect the gun cable to the gun receptacle (5) and tighten the cable
nut securely.
6. Connect the powder hose to the hose connector (2). The connector can
be disconnected from the gun by unscrewing the retainer nut (1) and
