Grounding the System
WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of a fire, explosion,
and serious injury, proper electrical
grounding of every part of your system is
essential. Read the warning section,
FIRE AND EXPLOSION HAZARD, on
page 4 and follow the grounding
instructions below.
The following grounding instructions are minimum
requirements for a basic dispensing 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. Fluid hoses: use only grounded fluid hoses with a
maximum of 25 feet (7.5 m) combined hose length
to ensure grounding continuity. Check the electrical
resistance of your fluid hoses at least once a
week. If your hose does not have a tag on it which
specifies the maximum electrical resistance,
contact the hose supplier or manufacturer for the
maximum resistance limits. If the hose resistance
exceeds the recommended limits, replace it imme-
diately.
2. 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.
3. Fluid supply container: ground according to the
local code.
4. Flammable liquids in the dispense area: must
be kept in approved, grounded containers. Do not
store more than the quantity needed for one shift.
5. 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-conductive surface, such as paper or card-
board, which interrupts the grounding continuity.
6. To maintain grounding continuity when flush-
ing or relieving pressure: hold a metal part of
the gun firmly to the side of a grounded metal pail,
then trigger the gun.
