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.
