Graco 3A0420T Manual De Usuario

1.

Locate the proportioner on a level surface.

2.

Position the proportioner for convenient operator 
access and maintenance, safe routing of air and 
fluid lines, and easy connection of components and 
accessories.

3.

For permanent mounting, remove wheels and 
mount the frame to the floor. See 

page 58.

4.

Ensure that the cart brake (L) is in the locked posi-
tion.

Pump: use ground wire and clamp (supplied). Loosen 
grounding lug locknut (W) and washer (X). Insert ground 
wire end (Y) into lug (Z) slot and tighten locknut 
securely. Connect ground clamp to a true earth ground.

Solvent Pump: use ground wire and clamp (supplied 
with solvent pump). Follow instructions in pump manual.

Air and fluid hoses: use only static dissipation type 
hoses with a maximum of 500 ft (150 m) combined hose 
length to ensure grounding continuity. Check electrical 
resistance of hoses regularly. If total resistance to 
ground exceeds 29 megohms, replace hose immedi-
ately. 

Air compressor: follow manufacturer’s recommenda-
tions.

 

ground through connection to a properly 

grounded fluid hose and pump.

Fluid supply container: follow local code.

Object being sprayed: follow local code.

Solvent pails used when flushing: follow local code. 
Use only conductive metal pails, placed on a grounded 
surface. Do not place the pail on a nonconductive sur-
face, such as paper or cardboard, which interrupts 
grounding continuity.

To maintain grounding continuity when flushing or 
relieving pressure: hold metal part of the spray gun 
firmly to the side of a grounded metal pail, then trigger 
the gun.

The XP35, XP50, and XP70 systems are approved 
for use in hazardous locations only if the base model, 
all accessories, all kits, and all wiring meet local, 
state, and national codes.

The equipment must be grounded. Grounding 
reduces the risk of static and electric shock by pro-
viding an escape wire for the electrical current due to 
static build up.
