Grounding the System
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section
FIRE AND EXPLOSION
HAZARD
on page 4.
1.
Fluid Pump (not provided):
use a ground wire and
clamp. See Fig. 2. Loosen the grounding lug
locknut (W) and washer (X). Insert one end of a 12
ga (1.5 mm
@
) minimum ground wire (Y) into the
slot in lug (Z) and tighten the locknut securely.
Connect the other end of the wire to a true earth
ground. For a ground wire and clamp, order Part
No. 237569.

2.
Air and fluid hoses:
Use only electrically conduc-
tive hoses.
3.
Air compressor:
follow manufacturer’s recommen-
dations.
4.
Spray gun or dispensing valve:
ground through
connection to a properly grounded fluid hose and
pump.
5.
Object being sprayed:
follow your local code.
6.
Fluid supply drum:
follow your local code.
7.
Solvent pails used when flushing:
follow your local
code. Use only metal pails, which are conductive
and placed on a grounded surface.
Do not
place
the pail on a nonconductive surface, such as paper
or cardboard which interrupts the grounding conti-
nuity.
8.
To maintain grounding continuity when flushing or
relieving pressure
, hold a metal part of the spray /
dispensing gun firmly to the side of a grounded
metal
pail, then trigger the gun.
Flushing the System Before Initial Use
Flushing the system before its initial use can prevent
material contamination, which may cause the material
to fail or perform poorly.
CAUTION
Flush the system before performing the initial
material loading procedure.
The system was facto-
ry tested using a light soluble oil, a soybean oil, or
some other oil as tagged. Flush the system to avoid
contaminating the material that has been designated
for initial material loading.
To flush the system, perform the following procedure:
1.
Select the material for the initial material load.
2.
Verify whether the factory-test oil and the initial
material load are compatible:
a.
If the two substances are compatible, omit the
remaining steps in this procedure and perform
the
Initial System Startup Procedure
on
page 11.
b.
If the two substances are incompatible, per-
form the remaining steps in this procedure to
flush the system.
WARNING
Use fluids and solvents that are chemically compat-
ible with the equipment wetted parts. See the
Technical Data
sections of all the equipment
manuals. Always read the material manufacturer’s
literature before using fluid or solvent in this equip-
ment.
To avoid damaging the unit do not use fluids con-
taining halogenated hydrocarbons (HHC) to flush or
clean the system as HHC is not compatible with
aluminum. See technical data on page 24 for a list
of wetted parts.
3.
Select a drum containing a compatible material
that can dissolve, clean, and eliminate the factory-
test oil from the system. If necessary, check with
the material supplier for a recommended flush ma-
terial.
4.
Before flushing, be sure the entire system and
flushing drums are properly grounded. Refer to
Ground the System
, on page 7.
5.
Perform the
Initial System Startup Procedure
steps
on page 11 to load the drum containing the
solvent.
6.
Run the flush material through the system for
approximately 1 to 2 minutes.
7.
Remove the drum containing the flush material.
