Grounding

ti24584a

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.

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

Grounding

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.

• 110-120V units require 100-120 VAC,

50/60 Hz, 13A, 1 phase.

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

8A, 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 mm minimum. NOTE: Smaller gauge or longer extension cords may reduce sprayer performance.

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.
