Perform the following steps to install the gun cable, powder feed hose,
and air tubing.
WARNING: All electrically conductive equipment in the spray
area must be grounded. Ungrounded or poorly grounded
equipment can store an electrostatic charge which can give
personnel a severe shock or arc and cause a fire or explosion.
NOTE: The spray gun is shipped with gun cable and air tubing
extensions connected to the back of the spray gun. This allows the gun
cable and air tubing connections to be made without having to
disassemble the spray gun.
NOTE: To increase powder flow and keep distribution of air in the
powder even, keep the powder feed hose as short as possible. The
powder feed hose should be no longer than 16 m (50 ft) long.
See Figure 3-2.
