Setup

Grounding

The equipment must be grounded.
Grounding reduces the risk of static and
electric shock by providing an escape wire
for the electrical current due to static build
up or in the event of a short circuit.
The following grounding instructions are mini-
mum requirements for a basic dispensing sys-
tem. The specific system being used may
include other equipment or objects that must
be grounded. Check local electrical codes for
detailed grounding instructions.
Pump: use ground wire and clamp (supplied
with pump). Connect ground clamp to a true
earth ground as shown in separate pump man-
ual.
Air and fluid hoses: use only electrically con-
ductive hoses with a maximum of 100 ft (30.5
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 total resistance to ground exceeds 25 meg-
ohms, replace the hose immediately.
NOTE: Use a meter that is capable of measur-
ing resistance at this level.
Air compressor: follow manufacturer's recom-
mendations.
Dispense valve: ground through connection
to a properly grounded fluid hose and pump.
3A1792A
Electric heated valves: Connect the electrical
cable plug to the connector on the heated
hose. Verify that pin 8 on the heated hose con-
nector is connected to a true earth ground.
See Wiring Diagram, page 29.
Fluid supply container: follow local code.
Object being sprayed: ground the object
being sprayed according to 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 ground-
ing continuity.
To maintain grounding continuity when
flushing or relieving pressure: hold metal
part of the dispense valve firmly to the side of a
grounded metal pail, then trigger the valve.

Flush Before Using Equipment

The equipment was tested with lightweight oil,
which is left in the fluid passages to protect
parts. To avoid contaminating your fluid with
oil, flush the equipment with a compatible sol-
vent before using the equipment.
