Installation  
Gun: the gun is grounded by connecting it to the  
properly grounded fluid hose and by a ground wire  
in the cable. Check ground continuity between the  
gun body and the heat control ground lug.  
Ground the System  
Fluid supply container: ground according to the  
local code.  
Flammable liquids in the dispense area: must be  
kept in approved, grounded containers. Do not store  
more than the quantity needed for one shift.  
The following grounding instructions are minimum  
requirements for a basic dispensing system. Your sys-  
tem may include other equipment or objects that 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.  
All solvent pails used when flushing: ground  
according to local code. Use only metal pails, which  
are conductive. Do not place the pail on a non-con-  
ductive surface, such as paper or cardboard, which  
interrupts the grounding continuity.  
Fluid hoses: use only grounded fluid hoses with a  
maximum of 25 feet (7.5 m) combined hose length  
to ensure grounding continuity. Check electrical  
resistance of your fluid hoses at least once a week.  
If your hose does not have a tag on it that specifies  
the maximum electrical resistance, contact the hose  
supplier or manufacturer for the maximum resis-  
tance limits. If the hose resistance exceeds the rec-  
ommended limits, replace it immediately.  
To maintain grounding continuity when flushing or reliev-  
ing pressure: hold a metal part of the gun firmly to the  
side of a grounded metal pail, then trigger the gun. To  
reduce the risk of static sparking, ground the pump,  
object being dispensed to, and all other spraying/dis-  
pensing equipment used or located in the spraying/dis-  
pensing area. Check your local electrical code for  
detailed grounding instructions for your area and type of  
equipment.
