WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE OR EXPLOSION
HAZARD on page 5.
1.
Pump: use the ground wire and clamp (supplied).
See Fig. 1. Loosen the grounding lug locknut (W)
and washer (X). Insert one end of the 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.

2.
Air and fluid hoses connected to the pump: Use
only electrically conductive hoses with a maximum
of 500 feet (150 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
29 megohms, replace the hose immediately.
NOTE: Use a meter that is capable of measuring
resistance at this level.
3.
Air compressor: follow manufacturer’s recommen-
dations.
4.
Spray gun/dispense valve: ground through connec-
tion to a properly grounded fluid hose and pump.
5.
Fluid supply container: follow your local code.
6.
Object being sprayed: follow your local code.
7.
Solvent pails used when flushing: follow 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 continu-
ity.
8.
To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Location
Position the ram so the air regulators for the pump and
the ram will be easily accessible. Ensure that there is
sufficient overhead clearance when the ram is fully
raised. Refer to Dimensions on page 19.
Using the holes in the ram base as a guide, drill four
holes for 1/2 in. (13 mm) anchors.
Check that the ram base is level in all directions. If
necessary, level the base using metal shims. Secure
the base to the floor using 13 mm (1/2 in.) anchors
which are long enough to prevent the ram from tipping.
Components and Accessories
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.
NOTE: Always use Genuine Graco Parts and Acces-
sories, available from your Graco distributor. Refer to
the Product Data Sheet, Form No. 305545 for Check-
Mate 200 Pumps. If you supply your own accessories,
be sure they are adequately sized and pressure rated
for your system.
Fig. 2 is only a guide for selecting and installing sys-
tem components and accessories. Contact your Graco
distributor for assistance in designing a system to suit
your particular needs.
