, and/or substantial property damage.
Information
HVLP Compressor/Cart Information
The
GTS–ProCart HVLP Compressor/Cart when used
with a turbine sprayer and turbine spray gun can spray
most coatings or finishes currently being used for
automotive refinish, industrial, aerospace, marine,
wood, plastic and architectural applications.
The cart/compressor provides air pressure to a 2–1/2
gallon remote pressure pot or a 2 quart pressure pot.
Under pressure, fluid is propelled from the pot to
turbine spray gun.
See Fig. 1 for Component Identification and Function.
HVLP System Operation
The
spray gun of the HVLP system utilizes inbound air
pressure from the cart/compressor and HVLP turbine
sprayer to produce a high quality paint finish. The
spray gun produces a cone of air that carries and
directs the paint from the gun to the surface. Over
-
spray is minimized. Application is easier since fewer
paint passes are required to obtain coverage. In
-
creased system transfer ef
ficiency reduces material
requirements and clean-up time. The system allows
compliance with clean air laws for reduced VOC (vola
-
tile organic compounds) emissions.
Refer to the HVLP turbine sprayer manual 824–170 for
information on the operation and use of the HVLP
turbine sprayer
. Refer to the turbine gun manuals,
308–336 or 308–810, for information on the operation
and use of the turbine spray gun.
Dif
ferent configurations of, HVLP compressor/carts,
turbine sprayers, guns, and accessories are available
to meet specific application requirements.
Unpacking
Unpack the Graco cart/compressor from the shipping
carton and inspect for any possible shipping damage.
If necessary
, call your distributor
.

Grounding
WARNING
Improper

plug will result in a risk of electric shock, fire or
explosion that could cause serious injury or death.
120 V
ac Systems
1.
This equipment requires a 120 V
ac, 60 Hz, 15A
circuit with a grounding receptacle. See Fig. 2.

Grounding
Prong
Grounded
Outlets
2. Do
not alter the ground prong or use an adapter
.
3.
A 12 A
WG gauge, 50 ft extension cord may be
used with this equipment.
Prepare the Fluid
1. Always
strain the fluid before spraying; this
includes color
, reducer and hardeners if used.
2.
When using a turbine spray system, you need to
use a slower drying reducer or thinner to compen
-
sate for the faster drying time caused by the warm
air of the turbine.
Do not over reduce.
NOTE:
The performance of the turbine sprayer will
vary with viscosity of material used and hose length.
Keep hose length short to prevent pressure drop.
Paint Reduction – Automotive Type Finishes
Reduce and catalyze all paint to manufacturer
’
s speci
-
fications. T
o compensate for the faster drying time of
turbine systems, use a reducer one-step slower than
what is used for conventional air spray
.
Paint Reduction – Industrial or Domestic Coatings
Reduce and catalyze all paint to manufacturer
’
s speci
-
fications. If no reductions are given, first thoroughly
mix the fluid to be sprayed. Then gradually mix in the
proper reducer
, testing the fluid until you have the
correct spraying consistency
.
T
o test the consistency:
Remove the stir stick from the
thinned paint. When the paint stream running of
f the
stir stick breaks into droplets, the first few drops should
be about one second apart.
Setup/Use Options
The
HVLP compressor/cart has a variety of user
options. See Fig. 3 for compressor/cart uses.
NOTES:
D
Refer to turbine manual 824–170 for information on

.
NOTE:
2 quart remote pressure pot only:
lightly coat
the cover threads with petroleum jelly
.
CAUTION
If the 2 quart remote pressure pot is accidentally
tipped over or held at too great of an angle, fluid may
leak into the air regulator and cause damage. T
