Installation  
NOTES:  
D Fluid supply container: ground according to your  
local code.  
D Reference numbers and letters in parentheses in  
the text refer to the callouts in the figures and  
drawings.  
D Flammable liquids in the spray area: must be in  
approved, grounded containers. Do not store more  
than the quantity needed for one shift.  
D Accessories are available from your Graco  
representative. If you supply your own accessories,  
be sure they are adequately sized and  
D All solvent pails used when flushing: ground  
according to local code. Use only metal pails, which  
are conductive. Do not place the pail on a  
non-conductive surface, such as paper or  
cardboard, which interrupts the grounding  
continuity.  
pressure-rated to meet the system’s requirements.  
Grounding  
WARNING  
D To maintain grounding continuity when flushing or  
relieving pressure, hold a metal part of the valve  
firmly to the side of a grounded metal pail, then  
trigger the valve.  
FIRE AND EXPLOSION HAZARD  
To reduce the risk of fire, explosion, and  
serious injury, proper electrical ground-  
ing of every part of your system is es-  
sential. Read the warning section Fire  
and Explosion Hazard on page 4, and  
follow the grounding instructions below.  
How to Use the Valve Trigger Safety  
WARNING  
SKIN INJECTION HAZARD  
To prevent accidental triggering of the  
gun and reduce the risk of a serious inju-  
ry, including fluid injection or splashing in  
the eyes or on the skin, lock the gun trigger safety  
when you stop dispensing.  
The following grounding instructions are minimum  
requirements for a basic dispensing system. Your  
system may include other equipment or objects which  
must be grounded. Check your local electrical code for  
detailed grounding instructions for your area and type  
of equipment. Your system must be connected to a  
true-earth ground.  
1. If you are using one of the hand-held versions of  
the valve, lock the valve trigger safety by turning  
the latch to a right angle with the gun body. See  
Fig. 2.  
D Pump: ground the pump by connecting ground wire  
and clamp as described in your separate pump  
instruction manual.  
2. To unlock the valve trigger safety, push the latch  
out and turn it parallel with the gun body.  
D Air compressors and hydraulic power supplies:  
ground the equipment according to the  
manufacturer’s recommendations.  
D Fluid hoses: use only grounded fluid hoses with a  
maximum of 500 feet (150 m) combined hose  
length to ensure grounding continuity. Check the  
electrical resistance of your fluid hoses at least  
once a week. If your hose does not have a tag on it  
which specifies the maximum electrical resistance,  
contact the hose supplier or manufacturer for the  
maximum electrical resistance limits, replace the  
hose immediately.
