Install the Spray Tip
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
Relieve the pressure. Install the spray tip and tip guard
as explained in your separate gun manual, supplied.
The fluid output and pattern width depend on the size
of the spray tip, the fluid viscosity, and the fluid pres-
sure. Use the Spray Tip Selection Chart in your gun
instruction manual as a guide for selecting an
appropriate spray tip for your application.
Adjust the Spray Pattern
WARNING
FIRE AND EXPLOSION HAZARD
Do not plug in or unplug the power cord
in any area containing flammable fluids
or fumes, to avoid fire or explosion
resulting in serious injury.
1. Start the pump. Plug in the heater power cord.
Turn the 3-way valve (45) to CIRC.
2. Set the heater control to a trial point (4 or 5).
3. Circulate fluid through the pump for at least 10
minutes, at very low pressure. Check the tempera-
ture on the heater thermometer.
4. Adjust the fluid pressure and temperature to the
lowest settings necessary to get the desired re-
sults. Use the air regulator (F) to adjust the pump
speed and fluid pressure until the spray is
completely atomized. Refer to the back pressure
valve and heater manuals (supplied) for adjust-
ment procedures. Higher pressures and tempera-
tures may not improve the spray pattern and will
cause premature component wear.

Operation
exceed 100 psi (0.7 MPa, 7 bar) air input pressure
to the package. Never exceed 100 psi (0.7 MPa, 7
bar) air input pressure to the spray gun. Also refer
to the Technical Data on page 22 and to your sep-
arate component manuals.
Heat causes fluid to expand. If the heated fluid is
trapped with nowhere to expand, it can cause
component rupture. Be sure to keep the heated
fluid circulating (turn the 3-way valve to CIRC). Do
not install a fluid shutoff device between the heater
and the gun.
5. When applying the fluid, keep the gun a consistent
distance, about 8 to 12 inches (200 to 300 mm)
from the surface of the object being sprayed.
Always hold the gun at a right angle from the
surface. Do not make an arc with the gun as it
causes an uneven coat of fluid. Use a full-open,
full-close triggering action. Practice to find the best
length and speed of stroke.
6. To adjust the spray pattern, follow the instructions
in your gun manual, supplied.
7. With the pump and lines primed, and with ade-
quate volume supplied, the pump will continue to
cycle as long as air is supplied and the back
pressure regulator is open.
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If your
pump is running too fast, stop it immediately and
check the fluid supply. If the container is empty and
air has been pumped into the lines, refill the con-
tainer and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your package, which could cause com-
ponent rupture and serious injury, never
