WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
To reduce the risk of fire, explosion, or
electric shock, the system must be
properly grounded. Follow the
Fire,
Explosion, and Electric Shock Hazard
warnings on page 3 and follow the
instructions below.
a.
Connect the ground wire (R) supplied to the
ProMix control ground lug (Q). See Fig. 6.
Connect the ground wire clamp to a true earth
ground as defined in your local code.
b.
Ground the other system components (includ-
ing fluid supply units and spray gun) as
instructed in their separate instruction manu-
als.
c.
Use only grounded air and fluid hoses.
d.
Ground the fluid supply container according to
your local code.
e.
Ground the object being sprayed according to
your local code.
f.
Ground the solvent pails according to your
local code. Use only metal pails, which are
conductive, placed on a grounded surface. Do
not place the pail on a nonconductive surface,
such as paper or cardboard, which interrupts
the grounding continuity.
g.
Maintain grounding continuity when purging or
relieving pressure.
Follow the instructions in
your separate gun manual for safely grounding
your gun while purging.
15. Check grounding continuity.
Have a qualified electrician check the resistance
between each ProMix component and the true
earth ground. The resistance must be less than 25
ohms. If the resistance is greater than 25 ohms, a
different ground site may be required. Do not
operate the system until the problem is corrected.
