Grounding

334730F 9

Grounding

This sprayer includes a ground wire with an

appropriate ground contact.

The plug must be plugged into an outlet that

is properly installed and grounded in

accordance with all local codes and

ordinances.

Do not modify the plug provided; if it does not

fit the outlet, have the proper outlet installed

by a qualified electrician.

Power Requirements

•100-120V units require 100-120 VAC,

50/60 Hz, 15A, 1 phase.

•230V units require 230 VAC, 50/60 HZ,

10A, 1 phase.

Extension Cords

Use an extension cord with an undamaged

ground contact. If an extension cord is

necessary, use a 3-wire, 12 AWG (2.5 mm2)

minimum.

NOTE: Smaller gauge or longer extension

cords may reduce sprayer performance.

Pails

Solvent and oil-based fluids: follow local

code. Use only conductive metal pails,

placed on a grounded surface such as

concrete.

Do not place pail on a non-conductive surface

such as paper or cardboard which interrupts

grounding continuity.

Always ground a metal pail: connect a

ground wire to the pail. Clamp one end to the

pail and the other end to a true earth ground

such as a water pipe.

To maintain ground continuity when

sprayer is flushed or pressure is relieved:

hold metal part of spray gun firmly to the side

of a grounded metal pail then trigger the gun.

The equipment must be grounded to

reduce the risk of static sparking and

electric shock. An electric or static spark

can cause fumes to ignite or explode. An

improper ground can cause electric shock.

A good ground provides an escape wire for

the electric current.
