WARNING

Installation
3A7469D 7
Installation
Grounding
Check your local electrical code and pump
or sprayer manual for detailed grounding
instructions.
Spray gun: ground through connection to a
properly grounded fluid hose and pump.
Fluid hose: use only electrically conductive
hoses with a maximum of 500 ft. (150 m)
combined hose length to ensure grounding
continuity. Check electrical resistance of
hoses. If total resistance to ground exceeds
29 megohms, replace hose immediately.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
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 nonconductive surface, such as
paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when
flushing or relieving pressure: hold metal
part of the spray gun firmly to the side of a
grounded metal pail, then trigger the gun.
System Requirements
•Install a bleed-type master air valve on a
pneumatic pump air supply line to relieve
air trapped between this valve and pump
after air regulator is shut off. Trapped air
can cause the pump to cycle
unexpectedly.
•Install a fluid drain valve between the
pump and gun to relieve pressure in
displacement pump, hose, and gun.
Triggering to relieve pressure may not
be sufficient. See the Pressure Relief
Procedure, page 9.
Gun Trigger Lock
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.
To prevent injury when the gun is not in
use, always engage the gun’s trigger lock
if unit is being shut down or left
unattended. A wallet-sized warning card
with important injection treatment
information is included with the gun.
Additional cards are available at no
charge. Provide a card to all operators.
The trigger lock must move freely, and
easily snap into the locked position. If the
trigger lock is damaged or movement is
restricted, replace with new trigger kit (16)
immediately.
