Grounding
3A4401A 9
Grounding
The sprayer cord includes a grounding wire
with an appropriate grounding 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.
Air and fluid hoses: Use only electrically
conductive hoses with a maximum of 500ft.
(150 m) combined hose length to ensure
grounding continuity. Check electrical
resistance of hoses. If total resistance to
ground exceeds 29 megaohms, replace hose
immediately.
Spray gun: Ground through connection to a
properly grounded fluid hose and pump.
Power Requirements
230V units require 230 VAC, 50/60 Hz, 16A,
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.
Grounding of Pails
Solvent pails used when flushing: Follow
local code. Use only conductive metal pails,
placed on a grounded surface. Do not place
the 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.
Circuit Protection
Connect sprayers only to circuits which have
the properly sized circuit breaker and/or
fuses (for unit power requirements see
Technical Specifications, page 49.
The equipment must be grounded to
reduce the risk of static sparking. Static
sparking can cause fumes to ignite or
explode. Grounding provides an escape
wire for the electric current.
