Installation
General Information
The T
ypical Installation shown in Fig. 2 is only a
guide for selecting and installing system compo
-
nents. Contact your Graco distributor or Graco
T
echnical Assistance (see back page) for assis
-
tance in planning a system to suit your needs.
Always use Genuine Graco Parts and Accessories.
Be sure all accessories are adequately sized and
pressure-rated to meet the system’s requirements.
Reference numbers and letters in parentheses refer
to the callouts in the figures and the parts lists on
pages 27–28.
V
ariations in color between the plastic components
of this pump are normal. Color variation does not
af
fect the performance of the pump.
T
OXIC FLUID HAZARD
Hazardous fluid or toxic fumes can
cause serious injury or death if splashed
in the eyes or on the skin, inhaled, or
swallowed.
1. Read T
OXIC FLUID HAZARD
on page 3.
2.
Use fluids and solvents which are compatible
with the equipment wetted parts. Refer to the
T
echnical Data
section of all equipment manu
-
als. Read the fluid and solvent manufacturer
’s
warnings.
WARNING
Tighten Screws Before First Use
After
unpacking the pump and before using it for the
first time, check and retorque the manifold screws
(106, 1
12) and the cover screws (107, 108). See
pages 18, 19, and 20 for torque specifications.
After the first day of operation, check and retorque the
screws again. Repeat this process every 2 months.
Grounding
FIRE AND EXPLOSION HAZARD
This pump must be grounded. Before
operating the pump, ground the system
as explained below. Also, read the sec
-
tion
FIRE AND EXPLOSION HAZARD,
on page 3.
Polypropylene and Kynar
are
not
conductive.
Attaching the ground wire to the grounding lug will
ground only the air motor
. When pumping conduc
-
tive flammable fluids,
always
make sure the fluid
has an electrical path to a true earth ground.
Possible methods of grounding the fluid are
through the fluid containers or piping. Contact your
Graco distributor for assistance in grounding your
system.
Never
use a polypropylene or a Kynar
pump with non-conductive flammable fluids as
specified by your local fire protection code. US
Code (NFPA 77 Static Electricity) recommends a
conductivity greater than 50 x 10
–12
Siemans/meter
(mhos/meter) over your operating temperature
range to reduce the hazard of fire. Consult your
fluid supplier to determine the conductivity or
resistivity of your fluid. The resistivity must be less
than 2 x 10
12
ohm-centimeters.
