Grounding

WARNING

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.

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.

D Pump: ground the pump by connecting ground wire

and clamp as described in your separate pump

instruction manual.

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.

D Dispensing valve: ground the valve by connecting it

DFluid supply container: ground according to your local code.

DFlammable liquids in the spray area: must be in approved, grounded containers. Do not store more than the quantity needed for one shift.

DAll 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.

DTo 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.

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.

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.

2.To unlock the valve trigger safety, push the latch out and turn it parallel with the gun body.
