Check Fluid Resistivity

WARNING

Fire, Explosion, and Electric Shock Hazard

Check the fluid resistivity in a non-hazard- ous area only. Resistance Meter 722886 and Probe 722860 are not approved for use in a hazardous area.

Failure to follow this warning could cause fire, explosion, or electric shock and result in serious injury and property damage.

Graco Part No. 722886 Resistance Meter and 722860 Probe are available as accessories to check that the resistivity of the fluid being sprayed meets the require- ments of an electrostatic air spray system.

Follow the instructions included with the meter and probe. Readings of 25 megohms-cm and above provide the best electrostatic results.

Installation

Check Fluid Viscosity

To check fluid viscosity you will need:

•a viscosity cup

•a stopwatch.

1.Completely submerge the viscosity cup in the fluid. Lift the cup out quickly, starting the stopwatch as soon as the cup is completely removed.

2.Watch the stream of fluid coming from the bottom of the cup. As soon as there is a break in the stream, shut off the stopwatch.

3.Record the fluid type, elapsed time, and size of the viscosity cup.

4.If the viscosity is too high or too low, contact the material supplier. Adjust as necessary.

Install the Fabric Cover

1.Install a fabric cover (XX) over the front of the gun and slide it back to cover the exposed tubing and hoses at the back of the manifold. See FIG. 9..

2.Route the exhaust tube (YY) outside the cover. This enables you to monitor the exhaust tube for the presence of any paint or solvent. See Check for Fluid Leakage on page 28. Strap down the exhaust tube to prevent it from moving around.
