INSTALLATION

WARNING
Pressure Relief Procedure
Always relieve the system pressure whenever you
stop spraying, and before installing, removing or
cleaning any parts to avoid serious bodily injury
from high pressure fluid trapped in the system.
Always follow this procedure: shut off the pump,
trigger the spray gun, engage the trigger safety,
and slowly open the drain valve(s). Leave the
drain valve(s) open until you are ready to use the
system again.
The dimensional drawing on the back page gives
measurements needed for installing pump on a custom
designed mounting. See ACCESSORIES on back page
for available Grace mounting accessories.
NOTE:
Reference numbers and letters in paren-
theses in the text refer to the Typical Installa-
tion, Fig 1, 2, and Parts Drawing.

System Accessories
Refer to the Typical Installation drawing and the AC-
CESSORIES section for assistance in setting up your
system. If you supply your own accessories, be sure
they are adequately sized to meet your system re-
quirements.
We recommend installing an air line filter (A) to remove
harmful dirt and moisture from your compressed air
supply, an air line oiler (8) for automatic pump lubrica-
tion, a bleed-type master air valve (C), and an air
regulator (D) to control pump speed and material
pressure. See Accessories on back page.
Downstream from the pump in the fluid line, we recom-
mend installing a fluid shutoff valve (F), a fluid filter (G),
a drain valve (El, and a fluid pressure regulator (G).
Air and fluid valves are used to shut off and/or relieve
pressures in the system before adding, removing or ser-
vicing any parts of the system.
Connect Hoses
Connect a grounded air line hose (K), a grounded fluid
hose (H 1 and a suction hose to your system.
Connect a suction hose or siphon tube to the 3/a
intake (M) of pump.
Connect a l/2 in. ID (minimum) grounded air supply
hose (K) to the pump's l/2 npt(f) air inlet or the air
regulator's inlet fitting.
