SIPHON FEED CUP HOOKUP
Air pressure for atomization is controlled by the regulator on the
air source. The amount of fluid is adjusted by the fluid control
knob on the gun, the paint viscosity, and the air pressure. The
siphon cup must be vented to the atmosphere.
PRESSURE FEED CUP HOOKUP
Air pressure for atomization is controlled by the regulator on
the air source. The fluid pressure is set by adjusting the cup
regulator. The amount of fluid is also adjusted by the fluid control
knob. This method is required for heavy fluids and when using
internal mix nozzle spraying. This method generally requires a
special fluid tip, needle and air cap set.
PRESSURE FEED TANK HOOKUP
This method is similar to the pressure feed cup hookup with
the added benefit of being able to orient the gun in any position
independent of the tank. This method is useful for medium
production or large scale spraying applications where large
quantities of paint are used.
For medium production spraying (single regulator setup on tank),
air pressure for atomization is controlled by the regulator at the
air source. The amount of fluid is adjusted by the regulator on the
paint pressure tank.
For portable painting operations (double regulator setup on tank),
air pressure for atomization and fluid supply is regulated by two
individual air regulators on the paint pressure tank.
PRESSURE FEED CIRCULATING HOOKUP
For heavy production spraying, air pressure for atomization is
controlled by the regulator on the air source, The fluid pressure is
regulated by a separate fluid regulator at the paint source.
GRAVITY FEED CUP HOOKUP
This popular method is similar to the siphon feed with cup except
that the paint cup is mounted above the spray gun. This creates
a positive fluid pressure in the fluid nozzle while providing better
balance and comfort for the operator.

ASSEMBLY
9
All parts on a spray gun should be screwed in hand tight at first;
this
will avoid the possibility of cross threading the parts. If the parts cannot be
turned by hand easily, make sure you have the correct parts, unscrew by
hand easily, make sure you have the correct part, unscrew, realign, and try
again. NEVER use undue force in mating parts.
1) Connect the paint cup to the fluid inlet nipple and tighten to ensure a good seal, using spanner.
Use of the supplied filter screen is optional. This filter helps protect against small particle
contaminants. See parts drawing for proper filter placement.
2) Wrap the threads on the air inlet nipples of the spray
gun and the regulator with a couple of layers of
PTFE tape to help prevent air leaks.
3) Connect the regulator to the air inlet nipple at the
base of the gun handle.
4) Connect the air supply to the air inlet nipple on the
regulator.
