Ground the System
WARNING
FIRE AND EXPLOSION HAZARD
Improper grounding could cause static
sparking, which could cause a fire or
explosion. To reduce the risk of property
damage or serious injury, follow the
grounding instructions below.
The following grounding instructions are minimum
requirements for a 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.
1. Pump: Ground the pump by connecting a ground
wire and clamp between the fluid supply and a true
earth ground as instructed in your separate pump
instruction manual.
2. Air compressors and hydraulic power sup-
plies:
Ground them according to the manufacturer
recommendations.
3. Air , fluid, and hydraulic hoses connected to
the pump : Use only grounded hoses with a maxi-
mum of 500 feet (150 m) combined hose length to
ensure grounding continuity. Check the electrical
resistance of your air and fluid hoses at least once
a week. If the resistance exceeds the recom-
mended limits, replace the hose immediately.
4. Spray gun: Ground the gun by connecting it to a
properly grounded fluid hose and pump.
5. Fluid supply container: Ground it according to
local code.
6. Object being sprayed: Ground it according to
local code.
7. All solvent pails used when flushing: Ground
them 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 card-
board, which interrupts the grounding continuity.
8. To maintain grounding continuity when flush-
ing or relieving pressure:
Always hold a metal
part of the gun firmly to the side of a grounded
metal pail, then trigger the gun.
